Inkqubo yokuvelisa i-electrode ngumxholo ongundoqo we-lithium yokuvelisa ibhetri yonke, ehambelana nokusebenza kwe-electrochemical yebhetri, kunye nomgangatho we-slurry ubaluleke kakhulu.

Enye, ithiyori esisiseko ye-slurry

I-lithium ion ibhetri ye-electrode slurry luhlobo lolwelo, ngokwesiqhelo lunokwahlulwa lube lulwelo lweNewtonian kunye nolwelo olungelulo olwaseNewtonian. Phakathi kwazo, i-non-Newtonian fluid inokwahlulwa ibe yi-dilatancy plastic fluid, ixesha elixhomekeke kwi-non-Newtonian fluid, i-pseudoplastic fluid kunye ne-binham yeplastiki ye-fluid. Ulwelo lwe-Newtonian lulwelo olusezantsi lwe-viscosity ekulula ukulukhubaza phantsi koxinzelelo kwaye uxinzelelo lwe-chear lulingana nezinga lokuguqulwa. Ulwelo apho uxinzelelo lwe-shear nakweyiphi na indawo ngumsebenzi womgca wesantya se-shear deformation. Ulwelo oluninzi kwindalo lulwelo lweNewtonian. Ulwelo oluninzi olusulungekileyo olunjengamanzi kunye notywala, ioyile encinci, izisombululo zekhompawundi yemolekyuli ephantsi kunye nesantya esisezantsi segesi eziqukuqelayo zizilwelo zeNewtonian.

Ulwelo lwe-non-newtonian lubhekisa kulwelo olungawonelisiyo umthetho wokulinga kaNewton we-viscosity, oko kukuthi, ubudlelwane phakathi koxinzelelo lokucheba kunye nesantya sokucheba alukho mgca. Ulwelo lwe-non-newtonian lufumaneka ngokubanzi ebomini, imveliso kunye nendalo. Iipolymers izisombululo ezigxininisiweyo kunye nokunqunyanyiswa kweepolymers ngokuqhelekileyo ayilulo lwe-Newtonian fluids. Ulwelo oluninzi lwebhayoloji ngoku luchazwa njengolwelo olungelulo olwaseNewtonian. Ulwelo lwe-non-newtonian lubandakanya igazi, i-lymph, kunye ne-cystic fluids, kunye “ne-semi-fluids” njenge-cytoplasm.

I-Electrode slurry yenziwe ngezinto ezahlukahlukeneyo ezinobunzima obuhlukeneyo kunye nobukhulu be-particle, kwaye ixutywe kwaye ihlakazwe kwisigaba esiqinileyo-solwelo. Udaka olwenziwe lulwelo olungelulo olwaseNewtonian. Udaka lwebhetri yeLithium lunokwahlulwa lube ludaka oluhle kunye nenegative slurry iindidi ezimbini, ngenxa yenkqubo yodaka (oyile, amanzi) eyahlukileyo, indalo yayo iya kwahluka. Nangona kunjalo, ezi parameters zilandelayo zingasetyenziselwa ukumisela iimpawu ze-slurry:

1. I-Viscosity ye-slurry

I-Viscosity ngumlinganiselo we-viscosity ye-fluid kunye nokubonakaliswa kwamandla olwelo kwi-friction yangaphakathi. Xa ulwelo luhamba, luvelisa ukukhuhlana kwangaphakathi phakathi kweemolekyuli zalo, ezibizwa ngokuba yi-viscosity yolwelo. I-Viscosity ibonakaliswa yi-viscosity, esetyenziselwa ukubonakalisa ukuchasana kwezinto ezinxulumene neempawu zolwelo. I-Viscosity yahlulwe ibe yi-viscosity eguqukayo kunye ne-viscosity enemiqathango.

I-Viscosity ichazwa njengeperi yamacwecwe ahambelanayo, indawo A, uGqr Apart, ezaliswe ngolwelo. Ngoku faka i-thrust F kwipleyiti ephezulu ukuvelisa utshintsho lwesantya se-DU. Ngenxa yokuba i-viscosity yolwelo idlulisela lo maleko wamandla ngokomaleko, umaleko ngamnye wolwelo nawo uhamba ngokufanelekileyo, wenze i- velocity gradient du/ Dr, ebizwa ngokuba yi-chear rate, emelwe yi-R ‘. I-F/A ibizwa ngokuba yi-chear stress, echazwa njenge-τ. Ubudlelwane phakathi kwesantya sokucheba kunye noxinzelelo lokucheba luloluhlobo lulandelayo:

(F/A) = eta (du/Dr)

I-Newtonian fluid ihambelana nefomula kaNewton, i-viscosity inxulumene kuphela nobushushu, hayi izinga lokucheba, τ lilingana no-D.

Ulwelo olungezo-newtonian aluhambelani nefomula kaNewton τ/D=f(D). I-viscosity kwi-τ/D enikiweyo yi-ηa, ebizwa ngokuba yi-viscosity ebonakalayo. I-viscosity yolwelo olungelulo olwase-Newtonian aluxhomekekanga kuphela kwiqondo lobushushu, kodwa nakwizinga lokucheba, ixesha, kunye nokucheba ukucheba okanye ukutyeba.

2. Iipropati ezinodaka

I-Slurry lulwelo olungelulo olwaseNewtonian, olungumxube oqinileyo wolwelo. Ukuze kuhlangatyezwane neemfuno zenkqubo yokugquma ilandelayo, uludaka kufuneka lube nezi mpawu zintathu zilandelayo:

① Ukusetyenziswa kwemali kakuhle. Ubumanzi bunokubonwa ngokuphazamisa udaka kunye nokuluvumela ukuba luhambe ngokwemvelo. Ukuqhubekeka kakuhle, ukucinywa nokucinywa okuthe gqolo kuthetha ukuba nombane okhoyo. Ulwelo lunxulumene nomxholo oqinileyo kunye ne-viscosity ye-slurry,

(2) leveling. The smoothness of the slurry affects the flatness and evenness of the coating.

③ Rheology. I-Rheology ibhekiselele kwiimpawu ze-deformation ye-slurry ekuhambeni, kwaye iimpawu zayo zichaphazela umgangatho we-pole sheet.

3. Isiseko sokusasazwa kwe-slurry

I-lithium ion ibhetri ye-electrode yokwenziwa, i-cathode paste ngokunamathela, i-agent eqhubayo, ukubunjwa kwezinto ze-cathode; I-paste engalunganga yenziwe nge-adhesive, i-graphite powder kunye nokunye. Ukulungiswa kwe-slurry emihle kunye nembi ibandakanya uluhlu lweenkqubo zobuchwepheshe, ezifana nokuxuba, ukuchithwa kunye nokusabalalisa phakathi kwezinto ezinolwelo kunye nolwelo, ulwelo kunye nezinto eziqinileyo, kwaye zihamba kunye nokutshintsha kweqondo lokushisa, i-viscosity kunye nokusingqongileyo kule nkqubo. Inkqubo yokuxuba kunye ne-dispersion ye-lithium ion ibhetri ye-slurry inokwahlulwa ibe yinkqubo yokuxuba i-macro kunye nenkqubo ye-dispersion micro, ehlala ihamba kunye nenkqubo yonke ye-lithium ion ibhetri yokulungisa i-slurry. Ukulungiswa kodaka ngokubanzi kuhamba kwezi zigaba zilandelayo:

① Umxube womgubo owomileyo. Amalungu anxibelelana ngohlobo lwamachaphaza, amachaphaza, iinqwelomoya, kunye nemigca,

② Inqanaba lokuxova udaka olomileyo. Kule nqanaba, emva kokuba i powder eyomileyo ixutywe ngokulinganayo, i-binder liquid okanye i-solvent yongezwa, kwaye izinto eziluhlaza zimanzi kwaye zinodaka. Emva kokuphazamiseka okunamandla komxube, izinto eziphathekayo zixhomekeke kwi-shear kunye ne-friction of force mechanical, kwaye kuya kubakho ukungqubuzana kwangaphakathi phakathi kweengqungquthela. Ngaphantsi kwamandla ngamnye, amasuntswana ezinto ezikrwada athande ukusasazeka kakhulu. Eli nqanaba linempembelelo ebaluleke kakhulu kubukhulu kunye ne-viscosity ye-slurry egqityiweyo.

③ Inqanaba lokuncipha kunye nokusasazwa. Emva kokuxova, i-solvent yongezwa ngokucothayo ukulungisa i-slurry viscosity kunye nomxholo oqinileyo. Kweli nqanaba, ukusasazeka kunye ne-agglomeration zihlala kunye, kwaye ekugqibeleni zifikelele kuzinzo. Kweli nqanaba, ukusasazwa kwemathiriyeli kuchaphazeleka ikakhulu ngamandla oomatshini, ukuxhathisa phakathi komgubo kunye nolwelo, amandla okucheba ngesantya esiphezulu, kunye nentsebenziswano yempembelelo phakathi kodaka kunye nodonga lwesikhongozeli.

Umfanekiso

Uhlalutyo lweeparamitha ezichaphazela iipropati ezinodaka

It is an important index to ensure the consistency of the battery in the process of battery production that the slurry should have good stability. With the end of the combined slurry, mixing stops, slurry will appear settlement, flocculation and other phenomena, resulting in large particles, which will have a greater impact on the subsequent coating and other processes. The main parameters of slurry stability are fluidity, viscosity, solid content and density.

1. I-Viscosity ye-slurry

I-viscosity ezinzileyo kunye efanelekileyo ye-electrode paste ibaluleke kakhulu kwinkqubo yokwaleka kwephepha le-electrode. I-viscosity iphezulu kakhulu okanye iphantsi kakhulu ayihambisani ne-polar piece coating, i-slurry ene-viscosity ephezulu ayilula ukugqithiswa kwaye i-dispersion iya kuba ngcono, kodwa i-viscosity ephezulu ayihambisani nesiphumo sokulinganisa, ayihambisani nokugqoka; I-Viscosity ephantsi kakhulu ayilungile, i-viscosity iphantsi, nangona ukuhamba kwe-slurry kulungile, kodwa kunzima ukuyomisa, ukunciphisa ukomisa ukusebenza kakuhle kwe-coating, i-coating cracking, i-slurry particle agglomeration, i-face density consistency ayilungile.

Ingxaki ehlala isenzeka kwinkqubo yethu yokuvelisa kukutshintsha kwe-viscosity, kwaye “utshintsho” apha lunokwahlulwa lube yinguqu ekhawulezileyo kunye notshintsho olusisigxina. Utshintsho oludlulayo lubhekiselele kutshintsho olukhulu kwinkqubo yovavanyo lwe-viscosity, kwaye utshintsho olusisigxina lubhekiselele kutshintsho lwe-viscosity emva kwexesha. I-viscosity iyahluka ukusuka phezulu ukuya phantsi, ukusuka phezulu ukuya phezulu. Ngokuqhelekileyo, izinto eziphambili ezichaphazela i-viscosity slurry yisantya sokuxuba udaka, ulawulo lwexesha, umyalelo wezithako, ubushushu bendalo kunye nokufuma, njl. I-viscosity ye-slurry inqunywe ngokuyisiseko sisibophelelo. Khawucinge ukuba ngaphandle kwe-binder ye-PVDF / CMC / SBR (FIG. 2, 3), okanye ukuba i-binder ayihlanganisi into ephilayo kakuhle, ngaba i-slid live matter kunye ne-conductive agent yenza i-non-Newtonian fluid kunye neengubo ezifanayo? Musa ukwenza! Ke ngoko, ukuhlalutya kunye nokusombulula isizathu sokutshintsha kwe-slurry viscosity, kufuneka siqale kubume be-binder kunye ne-slurry dispersion degree.

Umfanekiso

IKHIWANE. 2. Ubume bemolekyuli yePVDF

Umfanekiso

Umzobo 3. Ifomula yemolekyuli yeCMC

(1) i-viscosity iyanda

Iinkqubo ezahlukeneyo zodaka zinemithetho eyahlukeneyo yokutshintsha i-viscosity. Okwangoku, inkqubo yodaka oluqhelekileyo ludaka oluhlelekayo lwePVDF/NMP inkqubo yeoli, kunye ne-negative slurry yigraphite/CMC/SBR inkqubo yamanzi.

① I-viscosity yodaka olulungileyo luyanda emva kwethuba lexesha. Esinye isizathu (ukubekwa kwexesha elifutshane) kukuba isantya sokuxuba i-slurry sikhawuleza, i-binder ayichithwanga ngokupheleleyo, kwaye i-PVDF powder iyachithwa ngokupheleleyo emva kwexesha elithile, kwaye i-viscosity iyanda. Ngokuqhelekileyo, i-PVDF idinga ubuncinane iiyure ze-3 ukuba ichithe ngokupheleleyo, kungakhathaliseki ukuba isantya esichukumisayo asikwazi ukuguqula le nto impembelelo, okubizwa ngokuba “ukukhawuleza kwenza inkunkuma”. Isizathu sesibini (ixesha elide) kukuba kwinkqubo yokuma kwe-slurry, i-colloid iyatshintsha ukusuka kwi-sol state ukuya kwi-gel state. Ngeli xesha, ukuba i-homogenized ngesantya esicothayo, i-viscosity yayo inokubuyiselwa. Isizathu sesithathu kukuba isakhiwo esikhethekileyo senziwe phakathi kwe-colloid kunye nezinto eziphilayo kunye neengqungquthela ze-agent eqhubayo. Le meko ayinakuguqulwa, kwaye i-slurry viscosity ayikwazi ukubuyiselwa emva kokunyuka.

The viscosity of the negative slurry increases. The viscosity of the negative slurry is mainly caused by the destruction of the molecular structure of the binder, and the viscosity of the slurry is increased after the oxidation of the molecular chain fracture. If the material is excessively dispersed, the particle size will be greatly reduced, and the viscosity of the slurry will also be increased.

(2) i-viscosity iyancitshiswa

① I-viscosity yodaka oluhle iyahla. Esinye sezizathu, i-adhesive colloid iguqula umlingiswa. Kukho izizathu ezininzi zokutshintsha, njengamandla anamandla okucheba ngexesha lokudluliselwa kwe-slurry, utshintsho olusemgangathweni lokufunxa kwamanzi nge-binder, utshintsho lwesakhiwo kunye nokuthotywa kwayo kwinkqubo yokuxuba. Isizathu sesibini kukuba ukushukuma okungalinganiyo kunye nokusabalalisa kukhokelela kwindawo enkulu yokuhlala yezinto eziqinileyo kwi-slurry. Isizathu sesithathu kukuba kwinkqubo yokuvuselela, i-adhesive ixhomekeke kwi-shear force enamandla kunye ne-friction yezixhobo kunye nezinto eziphilayo, kunye nokutshintsha kweepropati kwiqondo lokushisa eliphezulu, okubangelwa ukuhla kwe-viscosity.

The viscosity of the negative slurry decreases. One of the reasons is that there are impurities mixed in CMC. Most of the impurities in CMC are insoluble polymer resin. When CMC is miscible with calcium and magnesium, its viscosity will be reduced. The second reason is sodium hydroxymethyl cellulose, which is mainly the combination of C/O. The bond strength is very weak and easily destroyed by shear force. When the stirring speed is too fast or the stirring time is too long, the structure of CMC may be destroyed. CMC plays a thickening and stabilizing role in the negative slurry, and plays an important role in the dispersion of raw materials. Once its structure is destroyed, it will inevitably cause slurry settlement and viscosity reduction. The third reason is the destruction of SBR binder. In the actual production, CMC and SBR are usually selected to work together, and their roles are different. SBR mainly plays the role of binder, but it is prone to demulsification under long-term stirring, resulting in bond failure and viscosity reduction of slurry.

(3) Iimeko ezikhethekileyo (ijeli ngexesha elifanelekileyo eliphezulu naphantsi)

Kwinkqubo yokulungiselela i-paste enhle, i-paste ngamanye amaxesha ijika ibe yi-jelly. Kukho izizathu ezibini eziphambili zoku: okokuqala, amanzi. Ukuqwalasela ukuba ukufunxa ukufuma kwezinto eziphilayo kunye nokulawulwa komswakama kwinkqubo yokuxuba akulungile, ukufunxa ukufuma kwezinto eziluhlaza okanye ukufuma kwendawo yokuxuba kuphezulu, okubangelwa ukufunxa kwamanzi nge-PVDF kwijeli. Okwesibini, ixabiso le-pH le-slurry okanye izinto eziphathekayo. Ukuphakama kwexabiso le-pH kukuba, ulawulo lomswakama lungqongqo ngakumbi, ngakumbi ukuxuba izinto eziphezulu ze-nickel ezifana ne-NCA kunye ne-NCM811.

I-viscosity ye-slurry iguquguquka, esinye sezizathu ezinokuthi i-slurry ayizinzi ngokupheleleyo kwinkqubo yokuvavanya, kwaye i-viscosity ye-slurry ichaphazeleka kakhulu ngubushushu. Ngokukodwa emva kokusasazwa ngesantya esiphezulu, kukho iqondo lokushisa elithile kwiqondo lokushisa langaphakathi le-slurry, kwaye i-viscosity yeesampuli ezahlukeneyo ayifani. Isizathu sesibini kukusasazwa kakubi kwe-slurry, izinto eziphilayo, i-binder, i-agent eqhubayo ayisasazeki kakuhle, i-slurry ayikho i-fluidity enhle, i-viscosity ye-slurry yendalo iphezulu okanye iphantsi.

2. Ubungakanani bodaka

Emva kokuba i-slurry idibaniswe, kuyimfuneko ukulinganisa ubungakanani bayo, kwaye indlela yokulinganisa ubungakanani be-particle ngokuqhelekileyo i-scraper method. Ubungakanani be-particle yiparameter ebalulekileyo yokubonakalisa umgangatho we-slurry. Ubungakanani be-particle bunempembelelo ebalulekileyo kwinkqubo yokugquma, inkqubo yokuqengqeleka kunye nokusebenza kwebhetri. Ngokwethiyori, incinci isayizi ye-slurry, ingcono. Xa ubukhulu be-particle bukhulu kakhulu, ukuzinza kwe-slurry kuya kuchaphazeleka, i-sedimentation, i-slurry consistency ihluphekile. Kwinkqubo yokwaleka kwe-extrusion, kuya kubakho imathiriyeli yokuthintela, i-pole yome emva komgodi, okukhokelela kwiingxaki zomgangatho wepali. Kule nkqubo ilandelayo yokuqengqeleka, ngenxa yoxinzelelo olungalinganiyo kwindawo yokwambatha embi, kulula ukubangela ukuqhekeka kwepali kunye nee-micro-cracks zendawo, eziya kubangela ingozi enkulu ekusebenzeni kwebhayisikile, ukusebenza komlinganiselo kunye nokusebenza ngokukhuselekileyo kwebhetri.

Izinto ezisebenzayo ezintle nezimbi, izinto ezincamathelayo, ii-conductive agents kunye nezinye izinto eziphambili ezinobukhulu obuhlukeneyo kunye noxinaniso. Kwinkqubo yokuvuselela, kuya kubakho ukuxuba, i-extrusion, i-friction, i-agglomeration kunye nezinye iindlela zoqhagamshelwano ezahlukeneyo. Kwizigaba zemathiriyeli ekrwada ixutywa ngokuthe ngcembe, imanziswe sisinyibilikisi, ukuqhekeka kwezinto ezinkulu kwaye ngokuthe ngcembe zithande ukuzinza, kuya kubakho ukuxubana kwezinto ezingalinganiyo, ukunyibilika okuncamathelayo okungekuhle, ukudityaniswa okunzulu kwamasuntswana amahle, utshintsho kwiimpawu zokuncamathelisa kunye nezinye iimeko, eziya kuthi. kukhokelela ekuveliseni amasuntswana amakhulu.

Emva kokuba siqonde oko kubangela ukuba amaqhekeza avele, kufuneka sijongane nale ngxaki ngamachiza afanelekileyo. Ngokuphathelele ukuxuba umgubo owomileyo wezinto eziphathekayo, mna ndicinga ukuba isantya somxube sinempembelelo encinci kwiqondo lokuxuba umgubo owomileyo, kodwa bafuna ixesha elaneleyo lokuqinisekisa ukufana komxube womgubo owomileyo. Ngoku abanye abavelisi bakhetha i-adhesive powdery kwaye abanye bakhetha isisombululo solwelo sokuncamathelisa okulungileyo, izincamathelisi ezimbini ezahlukeneyo zimisela inkqubo eyahlukileyo, ukusetyenziswa kwe-adhesive powdery kufuna ixesha elide ukunyibilika, kungenjalo emva kwexesha kuya kubonakala ukudumba, ukuphindaphinda, utshintsho lwe-viscosity, njl. i-agglomeration phakathi kwamasuntswana amahle ayinakuphepheka, kodwa kufuneka siqinisekise ukuba kukho ukukhuhlana okwaneleyo phakathi kwezinto ukwenzela ukuba amasuntswana agglomeration abonakale e-extrusion, etyumzayo, enceda ukuxuba. Oku kufuna ukuba silawule umxholo oqinileyo kwizigaba ezahlukeneyo ze-slurry, umxholo ophantsi kakhulu oqinileyo uya kuchaphazela ukusasazeka kwe-friction phakathi kwamaqhekeza.

3. Umxholo oqinileyo wodaka

Umxholo oqinileyo we-slurry uhambelana ngokusondeleyo nokuzinza kwe-slurry, inkqubo efanayo kunye nefomula, iphakamileyo umxholo oqinileyo we-slurry, i-viscosity enkulu, kunye nokunye. Kuluhlu oluthile, i-viscosity ephezulu, iphezulu ukuzinza kwe-slurry. Xa siyila ibhetri, ngokubanzi sifumanisa ubukhulu be-core-core ukusuka kumthamo webhetri ukuya kuyilo lwephepha le-electrode, ngoko ke uyilo lwephepha le-electrode lihambelana kuphela noxinzelelo lomphezulu, ukuxinana kwezinto eziphilayo, ubukhulu. kunye nezinye iiparameters. Iiparamitha zephepha le-electrode zihlengahlengiswa yi-coater kunye ne-roller press, kwaye umxholo oqinileyo we-slurry awunayo impembelelo ngqo kuyo. Ke, ngaba inqanaba lomxholo oqinileyo we-slurry lincinci?

(1) Umxholo oqinileyo unempembelelo ethile ekuphuculeni ukusebenza kakuhle kokuvuselela kunye nokusebenza kakuhle kokwambathisa. Ukuphakama komxholo oqinileyo, ixesha elifutshane lokuvuselela, ukusetyenziswa kwe-solvent encinci, iphezulu ukomisa ukomisa ukusebenza kakuhle, ukonga ixesha.

(2) Umxholo oqinileyo uneemfuno ezithile zezixhobo. I-Slurry enomxholo ophezulu oqinileyo inelahleko ephezulu kwisixhobo, kuba iphezulu umxholo oqinileyo, ubuzaza ngakumbi isixhobo sokunxiba.

(3) I-slurry enomxholo ophezulu oqinileyo uzinzile ngakumbi. Iziphumo zovavanyo lokuzinza kwezinye i-slurry (njengoko kuboniswe kumzobo ongezantsi) zibonisa ukuba i-TSI (instability index) ye-1.05 ekuvuseleleni okuqhelekileyo iphezulu kune-0.75 kwinkqubo yokuvuselela i-high-viscosity, ngoko ukuzinza kwe-slurry kufunyenwe yi-high-viscosity. inkqubo yokuvuselela ingcono kunaleyo ifunyenwe ngenkqubo eqhelekileyo yokuvuselela. Kodwa i-slurry enomxholo ophezulu oqinileyo iya kuchaphazela umbane wayo, onzima kakhulu kwizixhobo kunye neengcali zenkqubo yokugquma.

Umfanekiso

(4) I-slurry enomxholo ophezulu oqinileyo inokunciphisa ubukhulu phakathi kweengubo kunye nokunciphisa ukuxhathisa kwangaphakathi kwebhetri.

4. Ubuninzi be-Pulp

Ubuninzi besayizi yiparameter ebalulekileyo ukubonisa ukuhambelana kobukhulu. Isiphumo sokusasazeka kobukhulu sinokuqinisekiswa ngokuvavanya ubuninzi bobungakanani kwiindawo ezahlukeneyo. Kule nto ayiyi kuphinda iphindwe, ngesishwankathelo esingentla, ndiyakholwa ukuba silungiselela i-electrode paste enhle.
