Njengexesha lenkxaso-mali yelizwe lam elitsha lemoto yemoto yehla ngokupheleleyo, i-LG Chem, i-Samsung SDI, i-Panasonic kunye namanye amandla aphesheya kwe-lithium-ion ibhetri yeengxilimbela ziqokelela amandla azo ngasese, zijonge ukuthatha ithuba lenzuzo ekhokelayo kwi-nugget engeyiyo ezayo. imarike exhaswa ngemali.

Enye yeenzuzo zabo eziphambili luphando lwetekhnoloji yebhetri kunye nenzuzo yophuhliso ekhokelela kuphuhliso lweshishini lebhetri ye-lithium-ion yamandla ehlabathi.

➤LG Chem: Uphando olusisiseko + utyalo-mali oluphezulu oluqhubekayo

I-LG Chem isebenzisana nee-OEM ezigubungela iimveliso ezininzi zehlabathi ezifana neMelika, iJapan kunye neKorea. Ineenzuzo zophando olunzulu kwicandelo lezinto ezisisiseko, kwaye kwangaxeshanye ijonga “iZiko loPhuhliso lweBattery yeMoto” njengombutho ozimeleyo okwicandelo leshishini lebhetri, njengoko kubonisiwe kulo mfanekiso ulandelayo:

Ngamashumi eminyaka yeenzuzo kuphando lwezinto eziphathekayo, i-LG Chem inokwazisa itekhnoloji ekhethekileyo kwizinto ezintle nezimbi, abahluli, njl., Kuyilo lwemveliso okokuqala, kwaye ibonise ngokuthe ngqo iteknoloji ekhethekileyo kuphando lweseli kunye nenkqubo yophuhliso. Iyakwazi ukubonelela yonke iphothifoliyo yemveliso ehambelana namandla eebhetri ze-lithium-ion ukusuka kwiSeli, imodyuli, i-BMS, kunye nophuhliso lwePakethi kwinkxaso yobugcisa.

Ukuxhasa uphando kunye nophuhliso lwetekhnoloji ye-LG Chem lugcina utyalo-mali oluphezulu lwenkunzi. Ngokwedatha yophando, inkxaso-mali iyonke ye-LG Chem ye-R&D kunye notyalo-mali lwabasebenzi luqhubekile nokunyuka ukusukela ngo-2013. Ngo-2017, utyalo-mali lwe-R&D lufikelele kwi-3.5 yeebhiliyoni zeeyuan (RMB), lubekwe kwindawo yokuqala phakathi kweenkampani zebhetri zehlabathi kutyalo-mali lwe-R&D ngaloo nyaka.

Izibonelelo zezibonelelo zezinto eziluhlaza kunye nokukwazi ukuzimela koqhagamshelwano lwemveliso kunika isiqinisekiso esiqinileyo se-LG Chem ye-ternary soft package kunye neendleko eziphezulu ezibanzi kunye nemigangatho ephezulu yobugcisa.

Ngokumalunga nokuphuculwa kwendlela yobugcisa, i-LG Chem okwangoku isebenza nzima ukusuka kwiphakheji ethambileyo ye-NCM622 ukuya kwi-NCM712 okanye i-NCMA712.

Kudliwanondlebe namajelo eendaba, i-CFO ye-LG Chemical yachaza ukuba indlela yokuphucula izinto ze-electrode yenkampani ukusuka kwi-622 ukuya kwi-712 okanye nakwi-811, i-LG inezicwangciso ezihlukeneyo zokumatanisa indlela yephakheji ethambileyo kunye nendlela ye-cylindrical kunye nokusetyenziswa komlambo osezantsi. iimodeli (iphakheji ethambileyo ayiyi kuphuhliswa ixesha 811 , Kwaye i-cylindrical NCM811 okwangoku isebenza kuphela kwiibhasi zombane).

Nangona kunjalo, nokuba yi-NCMA ye-electrode efanelekileyo okanye i-NCM712 ye-electrode efanelekileyo, isicwangciso sokuvelisa ubuninzi be-LG Chem sicwangciselwe ubuncinci iminyaka emibini, ebaluleke kakhulu kunesicwangciso sendlela ye-nickel ephezulu ye-Panasonic.

➤Samsung SDI: Intsebenziswano namaziko ophando + utyalo-mali oluqhubekayo olukwizinga eliphezulu

I-Samsung SDI ithatha imodeli yentsebenziswano efana naleyo ye-CATL kwinkalo yophando kunye nophuhliso: isebenzisana namaziko ophando eyunivesithi yasekhaya nakwamanye amazwe ukuseka imiba ebalulekileyo yobugcisa, ukusombulula uphuhliso lwezorhwebo kunye, kunye nokukhuthaza ngokudibeneyo iiprojekthi zophando ukudala i-synergies.

▼Itshathi ye-Samsung SDI yoMbutho

I-Samsung SDI kunye ne-LG Chem zineendlela ezahlukeneyo zobugcisa. Ubukhulu becala zimile okwesikwere. Kwangaxeshanye, balandela ngenkuthalo ukuveliswa kweebhetri ezingama-21700. Izinto ze-cathode zisebenzisa ikakhulu i-ternary NCM kunye ne-NCA izinto. Nangona kunjalo, utyalo-mali lwayo kuphando kunye nophuhliso lunamandla kakhulu.

Ngokwedatha yophando, utyalo-mali lwe-R&D lwe-Samsung SDI ngo-2014 lufikelele kwi-620,517 yezigidi eziphumeleleyo, ezibalelwa kwi-7.39% yokuthengisa; Utyalo-mali lwe-R&D ngo-2017 luyi-2.8 yeebhiliyoni zeeyuan (RMB). Ngokuphathelele kwimiba ebalulekileyo kwicandelo leebhetri zesizukulwana esilandelayo kunye nemathiriyeli, ngokuxhasa uphuhliso lwamalungelo awodwa abenzi bamachiza anxulumene ngokusondeleyo nemiba, siya kuphonononga amalungelo awodwa abenzi bokukhuphisana kwaye sivule iindawo ezintsha zoshishino.

Ibhetri yeprismatic ye-Samsung SDI ifikelele kwinqanaba le-210-230wh/kg yoxinzelelo lwamandla.

Ngokutsho kuka-Wei Wei, usekela-mongameli we-Samsung SDI yelizwe lam kwiForam yeZithuthi zoMbane walo nyaka, i-Samsung iya kuphuhlisa ngamandla isizukulwana sesine seemveliso ezivela kwizinto ze-cathode (i-NCA indlela), i-electrolyte kunye neteknoloji ye-anode kwixesha elizayo. Emva kokuqalisa ibhetri yesizukulwana sesine kunye noxinzelelo lwamandla lwe-270-280wh / kg, iceba ukuqhubeka nokuphuhlisa imveliso yesihlanu kunye nesicwangciso samandla esicwangcisiweyo se-300wh / kg kwindlela ephezulu ye-nickel.

Umkhombandlela wophuhliso lwesikweri wenkampani ukwabandakanya “iibhetri ezinobude obuphantsi” ezinomgangatho ophuculweyo wemodeli, ukwaziswa kwezixhobo zokutshaja ngokukhawuleza, kunye neepakethe ezikhaphukhaphu ngokubanzi. Ukongeza kwiibhetri zeprismatic, i-Samsung SDI nayo inokwakheka kwintsimi yeebhetri eziqinileyo kunye neebhetri zecylindrical. Kwi-2017, i-Samsung SDI ibonise iibhetri eziqinileyo kunye neemodyuli zebhetri ezisekelwe kwiiseli ze-cylindrical ze-21700 kwi-North American Auto Show, ebonisa amandla okuphuhlisa kwiindlela ezininzi.

Kufanelekile ukukhankanya ukuba i-Samsung SDI ixhaswa yi-R&D yeQela le-Samsung elomeleleyo kunye namandla omthombo, kwaye ikwanako nokubonelela ngezisombululo zebhetri ze-lithium-ion kulo lonke ikhonkco loshishino.

➤Panasonic: Izibonelelo zangaphakathi zesilinda + ezixhasa uTesla

Kwi-1998, i-Panasonic yaqala ukuveliswa kweebhetri ze-lithium-ion ze-cylindrical kwiikhompyutheni ze-notebook kwaye yakha umgca wemveliso ohamba phambili kwishishini kwiibhetri ze-lithium-ion. NgoNovemba 2008, iPanasonic yazisa ukudibanisa kunye neSanyo Electric kwaye yaba ngumthengisi omkhulu wehlabathi weebhetri ze-lithium-ion.

I-Panasonic ye-R & D layout kwintsimi yamandla ebhetri ye-lithium-ion isekelwe kwintsebenziswano yexesha elide kunye neempawu ezifana neTesla kunye neToyota, igxile kwiimarike zaseJapan kunye neMelika. Isiseko esiluqilima esisiqokelele kwishishini lebhetri ye-lithium yabathengi iye yandisa inzuzo yendalo yendlela ye-cylindrical yetekhnoloji eqolileyo kunye nokuhambelana okuphezulu, kwaye iphumelele ubuninzi obunamandla kunye nemodyuli yebhetri yomjikelo ozinzileyo ofanelekileyo kwiimodeli zeTesla.

Ukujonga emva kwizizukulwana ezidlulileyo zeebhetri zePanasonic ezixhotyiswe ukusuka kwi-Roadster ukuya kwi-Model 3 namhlanje, ukuphuculwa kwinqanaba lendlela yezobugcisa kugxininiswe ekuphuculeni izinto ze-cathode kunye nobukhulu be-cylinder.

Ngokubhekiselele kwizinto ze-cathode, uTesla wasebenzisa i-lithium cobalt oxide cathodes kwiintsuku zokuqala, i-ModelS yaqala ukutshintshela kwi-NCA, kwaye ngoku ukusetyenziswa kwe-NCA ephezulu ye-nickel kwi-Model 3, i-Panasonic iye yaba yinkokeli yoshishino ekuphuculeni izinto ze-cathode ekuphishekeleni. yoxinaniso lwamandla aphezulu.

Ukongeza kwizinto ezintle ze-electrode, indlela ye-cylindrical iye yavela kwi-18650 uhlobo ukuya kuhlobo lwe-21700, kwaye umkhwa wokufuna umthamo omkhulu wombane weseli enye ikhokelwa yiPanasonic. Ngelixa kukhuthazwa ukuphuculwa kokusebenza kwebhetri, iibhetri ezinkulu zinciphisa ubunzima bolawulo lwenkqubo yokupakisha kunye nokunciphisa iindleko zezakhiwo zentsimbi kunye nokudibanisa okuqhubekileyo kweepakethi zebhetri, ngaloo ndlela ukunciphisa iindleko kunye nokwandisa amandla ombane.
