Cacisa ngokweenkcukacha izizathu ezithandathu zokuba kutheni iibhetri ze-ternary zihlala kwimarike edumileyo yezithuthi ezisulungekileyo zamandla amatsha.
Idatha ibonisa ukuba kwiinyanga ezine zokuqala zalo nyaka, ukuthunyelwa kwe-iron phosphate kunye ne-iron phosphate kuye kwanda xa kuthelekiswa nexesha elifanayo kunyaka odlulileyo. Phakathi kwazo, umthamo wokuthunyelwa kweebhetri ze-lithium iron phosphate yi-2.6Gwh, kwaye umthamo wokuthunyelwa kweebhetri ze-ternary lithium uphezulu njenge-771.51MWh.
Ukongezelela, izinga lokungena kwezixhobo ze-ternary kwizithuthi ezikhethekileyo kwi-2015 yayiyi-61%, kwaye imfuno yafikelela kwi-1.1GWh. Kwi-2016, izinga lokungena liya kufikelela kwi-65%, kwaye imfuno iya kuba yi-2.9Gwh; ngo-2020, izinga lokungena liya kufikelela kwi-80%, kwaye imfuno yemarike iya kuba yi-14.0Gwh.
Ingabonwa ukuba izinto ze-ternary kunye ne-lithium iron phosphate ngokuthe ngcembe zithatha i-mainstream ekusetyenzisweni kwezithuthi ezicocekileyo zombane, kwaye umlinganiselo wezinto ze-ternary uya kuba mkhulu kwaye ube mkhulu. Nangona kunjalo, indlela yezobugcisa eziza kuthatha izithuthi zombane ezihlambulukileyo kwixesha elizayo azixhomeki kuphela kwiteknoloji kunye nomgangatho weebhetri ze-lithium zamandla, kodwa nakwiimfuno zemarike kunye nokulawula amanyathelo.
Okokuqala, kutheni le nto izinto ezithathu zihlala kwezona ndlela ziphambili zezithuthi zombane ezisulungekileyo?
E-China, phakathi kwezithuthi ezihlambulukileyo zombane, iteknoloji ye-lithium yebhethri yeyona ndlela isetyenziswa kakhulu, ilandelwa yi-lithium iron phosphate ibhetri. Ngokuqinisekileyo, kwindlela efanayo yobugcisa, iiparitha zamandla e-lithium iibhetri eziphuhliswe ngabavelisi abahlukeneyo azifani. Ngokomzekelo, i-Tesla kunye ne-LG zisebenzisa izixhobo ze-ternary kwaye zineeparamitha ezahlukeneyo malunga nomgangatho webhetri, uluhlu lwebhetri, ubomi bomjikelezo, kunye noxinano lwamandla ebhetri. Kwaye ezinye iiparameters zihlala zitshintsha kunye nokuphuculwa okuqhubekayo kweteknoloji. Iiparamitha ezininzi ngamaxabiso apheleleyo.
Apha sithelekisa iingenelo kunye nokungonakali kwezixhobo ezahlukeneyo ze-lithium ibhetri ye-cathode ukuphendula umbuzo wokuba kutheni ezi zixhobo zintathu zihamba phambili kwiimoto ze-logistics.
Uhlalutyo olunzulu lwezizathu ezithandathu zokuba kutheni iibhetri ezintathu ezinkulu zithatha indawo yentengiso yezithuthi ezisulungekileyo zombane.
Uhlalutyo olunzulu lwezizathu ezithandathu zokuba kutheni iibhetri ezintathu ezinkulu zithatha indawo yentengiso yezithuthi ezisulungekileyo zombane.
Okokuqala, kunokubonwa kumzobo wokuba nokuba ukhuseleko lwesixhobo se-ternary alukho phezulu, uninzi lweenkampani zezithuthi ziya kuqwalaselwa ngokubanzi, okanye ziya kwamkela indlela ye-ternary ye-lithium ye-betri, enoluhlu oluphezulu lokuhamba, umthamo omkhulu okhethekileyo. , ubomi benkonzo ende, njl. inzuzo.
Okwesibini, i-mileage yezithuthi ezihlambulukileyo zombane zichaphazela iimeko zokusebenza kunye nokusebenza kakuhle kwezithuthi. Kwizithuthi zombane ezisulungekileyo, okubalulekileyo kukuphela kokuhanjiswa kwezinto, uthutho lwasezidolophini, izindlu kunye nezinye iimarike. Kuyafuneka ukuba kuqinisekiswe ukuba umsebenzi wothutho ugqityiwe ngosuku olunye, ngakumbi ngexesha leeyure eziphakamileyo ezifana ne-Double Eleven, kunye nohambo olukhulu. Inqanaba loluhlu luxhomekeke kwinani leebhetri kunye nokuhambelana kwenkqubo yokubonelela ngombane.
Okwesithathu, ngoku, inkxaso-mali karhulumente iyarhoxiswa, kwaye izibonelelo zomhlaba zihlala zincipha. Kwiindawo ezininzi, inkxaso-mali iphantsi njenge-400 ye-yuan nge-kilowatt ngeyure. Umzekelo, eJiangsu naseHangzhou, abanye abaqhubi bezithuthi ezisulungekileyo zombane bathi loo nkxaso-mali iphantsi , Ayikwazi ukudlala. Kwiinkampani zeemoto, kunengqiqo ukufuna indlela yobugcisa engabizi kakhulu. Iindleko zeebhetri ze-lithium zemoto ziphezulu. Okwangoku, uncediso-mali kwiindawo ezininzi luqhutyelwe phambili yinkampani, kwaye itekhnoloji yokwenziwa kwemoto yothutho ayiphakami njengezinye izithuthi. Iindleko zebhetri ye-lithium ye-lithium iphantsi kunebhetri ye-lithium yensimbi ye-phosphate, kwaye iimfuno zobugcisa azikho ngaphezu kwebhetri ye-lithium iron phosphate. Oku kusindisa kakhulu izibonelelo zentlalo kunye neendleko zokuvelisa. Okwesine, enye yezona zithende ezinkulu ze-Achilles ze-lithium iron phosphate yintsebenzo ephantsi yokushisa ephantsi, nokuba i-nano kunye ne-carbon coatings ayizisombululi le ngxaki. Uphononongo lubonise ukuba ibhetri enomthamo we-3500mAh, ukuba iqhutywe kwi–10 ° C, emva kwemijikelezo engaphantsi kwe-100 yokukhutshwa kwentlawulo, amandla ayo aya kubola ngokukhawuleza kwi-500mAh kwaye ngokusisiseko achithwa. Izinto ze-ternary zinokusebenza kakuhle kweqondo lokushisa eliphantsi, kwaye ukuthotywa kwenyanga yi-1 ukuya kwi-2%. Kwiqondo lokushisa eliphantsi, izinga layo lokuhla alikho phezulu njenge-lithium iron phosphate.
Okwesihlanu, izixhobo ze-terpolymer zihlala kwindawo ephambili, ubukhulu becala ngenxa yefuthe leenkampani zeemoto zangaphandle. Uninzi lwezithuthi zamandla amatsha kwiinkampani zemoto zangaphandle zisebenzisa iibhetri ze-lithium ze-ternary, uninzi lwazo ziiseli ze-18650. Kwakhona kunokubonwa kwiibhetshi ze-286 zezaziso zemoto entsha ukuba uninzi lwezithuthi zombane ezicocekileyo zisebenzisa iibhetri ze-18650 ze-ternary lithium. Inqanaba elinye lamandla ombane ligama eliqhelekileyo li-3.6V okanye i-3.7V; ubuncinci bokuphela kombane wokukhupha ngokuqhelekileyo yi-2.5-2.75V. Umthamo oqhelekileyo yi-1200 ~ 3300mAh. Ibhetri ye-18650, kodwa ukuhambelana kuhle kakhulu; ibhetri egciniweyo ingenziwa ibe nkulu (20Ah ukuya kwi-60Ah), enokunciphisa inani leebhetri, kodwa ukuhambelana kubi. Ngokuchaseneyo, kweli nqanaba, kunzima kubaxhasi bebhetri ukuba batyale imali eninzi yabasebenzi kunye nezixhobo zokuphucula inkqubo yokuvelisa iibhetri ezipakishweyo.
(2) Imilo kunye nobukhulu, ngenxa yokuba iintlobo ezintathu ezingundoqo zahlukile, kukho iiyantlukwano, kunye nobukhulu bohlobo olufanayo nabo bahlukile. Zintathu iindidi zeebhetri ze-ternary, enye yi-soft pack battery, efana ne-A123, iVientiane, kunye ne-polyfluorine. Enye ibhetri yecylindrical, njengekaTesla. Kukwakho neebhetri ze-square-shell hard-shell, ezifana ne-BYD kunye ne-Samsung. Phakathi kweefom ezintathu, ixabiso lemveliso yeegobolondo ezinzima liphezulu, lilandelwa ziingxowa ezithambileyo, kwaye ekugqibeleni iisilinda. Enye imbono kukuba ukhuseleko lwesikhwama esithambileyo siphezulu kunesilinda, kwaye isakhiwo se-cylinder senza kube nzima ukusombulula ngokupheleleyo ingxaki yokhuseleko. Okwangoku, uninzi lweetekhnoloji zokupakisha ezithambileyo ze-ternary zisetyenzisiwe kwiimoto zelizwe lam. Nangona kunjalo, iimfuno zobugcisa zokupakishwa okuguquguqukayo ziphezulu kakhulu, ngakumbi kwitekhnoloji yokupakisha. Ukupakishwa okulambathayo kuya kubangela iingxaki ezinjengokugquma nokuvuza, kwaye kubangele iingozi zokhuseleko. Ngamanye amazwi, ukusetyenziswa kweebhetri ze-ternary kusekelwe kumaqokobhe esinyithi esikwere. Iqokobhe lentsimbi elisikweri lineengenelo zokubeka emgangathweni, ukwahlulahlulwa ngokulula, kunye namandla athile aphezulu. Ukungalungi kwakhona kukuba isiphumo sokutshatyalaliswa kobushushu sibi.
3. Uyilo lwebhetri ye-lithium yamandla
Ubume bebhetri ye-lithium yamandla kufuneka icwangciswe ngokuhambelana ne-chassis yesithuthi sombane esicocekileyo, kuthathelwe ingqalelo ubunzima bomzimba kunye nezinye izinto, ngokubanzi kwi-trunk yesithuthi, ngokweemodeli ezahlukeneyo zombane ococekileyo. isithuthi solungiselelo. Ngokomzekelo, iilori kunye neelori ezincinci zicwangciswe ngokwahlukileyo. Isishwankathelo: 1. Kuyimfuneko ukuqwalasela indawo yokubeka ibhetri ye-lithium yamandla. 2. Yintoni umthwalo? Umthwalo wemoto. 4 ibhalansi. Kufuneka kubekho iimfuno ezithile zokusebenza zokutshatyalaliswa kobushushu. Ukwanelisa ubuncinci bokucoceka komhlaba, i-angle yokudlula i-longitudinal kunye nezinye iimfuno zokudlula. Ukuhlangabezana nemfuno eqhubekayo yokunxibelelana kwabantu nekhompyuter. Kufuneka ihambelane nemigaqo yongquzulwano lwesizwe. Inomgangatho othile weemfuneko zokutywinwa. Qinisekisa imfuno yombane onamandla aphezulu.
Ukongeza, ukulungelelaniswa kwebhetri ye-lithium yamandla kufuneka kuqwalaselwe ukhuseleko lomqhubi. Ukuba ihlelwe phantsi kwesihlalo, ukuba ibhetri ibamba umlilo, ixhoba lamva nje ngumqhubi. Ukuba uhlobisa umzantsi wenqwelo, into yokuqala ezisa intlekele ngumthwalo, kwaye umqhubi unethuba eliphezulu lokubaleka.
