Izindleko eziphezulu zezinto zokusetshenziswa zezinto ze-ternary nazo zizoba nomthelela omubi ekuthuthukisweni kwamabhethri e-ternary lithium. I-Cobalt iyinsimbi ebiza kakhulu kumabhethri anamandla. Ngemva kokusikeka okuningana, isilinganiso samanje se-cobalt ye-electrolytic ngethani singaba ngu-280000 yuan. Izinto zokusetshenziswa zebhethri ye-lithium iron phosphate zicebile nge-phosphorus nensimbi, ngakho-ke izindleko kulula ukuzilawula. Ngakho-ke, nakuba ibhethri ye-lithium ye-ternary ingathuthukisa kakhulu ububanzi bezimoto ezintsha zamandla, ukuze kucatshangelwe ukuphepha nezindleko, abakhiqizi abazange babeke phansi ucwaningo lobuchwepheshe nokuthuthukiswa kwebhethri ye-lithium iron phosphate.

Ngonyaka odlule, inkathi ye-Ningde ikhiphe ubuchwepheshe be-CTP (iseli to pack). Ngokusho kwedatha ekhishwe izikhathi ze-Ningde, i-CTP ingakhuphula izinga lokusetshenziswa kwevolumu yephakethe lebhethri ngo-15% -20%, inciphise inani lezingxenye zephakethe lebhethri ngo-40%, ikhulise ukusebenza kahle kokukhiqiza ngo-50%, futhi ikhulise ukuminyana kwamandla. yebhethri yephakethe ngo-10% -15%. Ku-CTP, amabhizinisi asekhaya afana ne-BAIC new energy (EU5), i-Weilai automobile (ES6), imoto ye-Weima kanye nemoto ye-Nezha abonise ukuthi azosebenzisa ubuchwepheshe benkathi ye-Ningde. Inkampani ekhiqiza amabhasi yase-Europe iVDL, nayo ithe izoyethula ungakapheli unyaka.

Ngaphansi komkhuba wokwehla koxhaso lwezimoto ezintsha zamandla, uma kuqhathaniswa nesistimu yebhethri ye-lithium engu-3 yuan enezindleko ezingaba ngu-0.8 yuan /wh, intengo yamanje engu-0.65 yuan /wh yohlelo lwe-lithium iron phosphate inenzuzo kakhulu, ikakhulukazi ngemuva ukuthuthukiswa kobuchwepheshe, ibhethri le-lithium iron phosphate manje selingakwazi ukukhulisa i-mileage yemoto ibe ngu-400 km, ngakho-ke isiqalile ukuheha ukunaka kwamabhizinisi amaningi ezimoto. Imininingwane ikhombisa ukuthi ekupheleni kwesikhathi soguquko loxhaso ngoJulayi 2019, umthamo ofakiwe we-lithium iron phosphate ubalelwa ku-48.8% usuka ku-21.2% ngo-Agasti uya ku-48.8% ngoDisemba.

U-Tesla, umholi wemboni oseneminyaka eminingi esebenzisa amabhethri e-lithium-ion, manje kufanele ehlise izindleko zawo. Ngokohlelo luka-2020 olusha loxhaso lwezimoto zamandla, amamodeli wetramu angashintshisani anamayuan angaphezu kuka-300000 awakwazi ukuthola uxhaso. Lokhu kwenze uTesla wacabanga ukusheshisa inqubo yokushintshela imodeli 3 kubuchwepheshe bebhethri ye-lithium iron phosphate. Muva nje, i-CEO ye-Tesla u-musk uthe engqungqutheleni yakhe elandelayo "yosuku lwebhethri", uzogxila emaphuzwini amabili, eyodwa ubuchwepheshe bebhethri obusebenza kahle, enye ibhethri yamahhala ye-cobalt. Ngokushesha nje lapho izindaba ziphuma, amanani entengo ye-cobalt yamazwe ngamazwe ehla.

Kubikwa futhi ukuthi inkathi ye-Tesla ne-Ningde ixoxa ngokubambisana kwebhethri ephansi ye-cobalt noma i-non-cobalt, futhi i-lithium iron phosphate ingahlangabezana nezidingo zemodeli eyisisekelo 3. Ngokusho koMnyango Wezimboni kanye nobuchwepheshe bolwazi, i-endurance mileage ye- imodeli eyisisekelo 3 imayelana 450km, ukuminyana amandla uhlelo ibhethri mayelana 140-150wh / kg, futhi umthamo kagesi ingqikithi mayelana 52kwh. Njengamanje, ukunikezwa kwamandla okuhlinzekwa yinkathi ye-Ningde kungenza kufike ku-80% ngemizuzu engu-15, futhi ukuminyana kwamandla ephakethe lebhethri elinomklamo ongasindi lingafinyelela ku-155wh / kg, okwanele ukuhlangabezana nezidingo ezingenhla. Abanye abahlaziyi bathi uma uTesla esebenzisa ibhethri ye-lithium iron, izindleko zebhethri eyodwa kulindeleke ukuthi zinciphise i-7000-9000 yuan. Kodwa-ke, uTesla uphendule ngokuthi amabhethri angenayo i-cobalt awasho ngempela amabhethri e-lithium iron phosphate.

Ngaphezu kwenzuzo yezindleko, ukuminyana kwamandla ebhethri le-lithium iron phosphate uma selifinyelele ophahleni lobuchwepheshe liye landa. Ekupheleni kukaMashi kulo nyaka, i-BYD yakhipha ibhethri layo eliyi-blade, elathi ukuminyana kwayo kwamandla kwakucishe kube ngama-50% ngaphezu kwebhethri yensimbi evamile ngevolumu efanayo. Ngaphezu kwalokho, uma kuqhathaniswa nephakethe lebhethri le-lithium iron phosphate yendabuko, izindleko zephakethe lebhethri le-blade zehliswa ngo-20% - 30%.

Okubizwa ngebhethri ye-blade empeleni kuwubuchwepheshe bokuqhubeka nokuthuthukisa ukusebenza kahle kokuhlanganiswa kwephakethe lebhethri ngokwandisa ubude beseli nokuthambisa iseli. Ngenxa yokuthi iseli elilodwa lide futhi liyisicaba, libizwa ngokuthi “blade”. Kuyaqondakala ukuthi izinhlobo ezintsha zezimoto zikagesi ze-BYD zizosebenzisa ubuchwepheshe be- “blade battery” kulo nyaka nangemva kwalokho.

Muva nje, uMnyango wezeziMali, uMnyango wezezimboni nobuchwepheshe bolwazi, uMnyango wezeSayensi nobuchwepheshe, kanye neKhomishana kazwelonke yezokuThuthukiswa nokuBuyekezwa bakhiphe ngokuhlanganyela isaziso sokulungisa nokuthuthukisa inqubomgomo yoxhaso lwezimoto ezintsha ezisebenza ngamandla, okubeke kwacaca ukuthi inqubo yokuthutha umphakathi kanye nokufakwa kukagesi wezimoto emikhakheni ethile kufanele isheshiswe, futhi izinzuzo zokuphepha nezindleko ze-lithium iron phosphate kulindeleke ukuthi zithuthukiswe. Kungabikezelwa ukuthi ngokusheshisa kancane kancane kwejubane lokufakwa kukagesi kanye nokwenza ngcono okuqhubekayo kobuchwepheshe obuhlobene bokuphepha kwebhethri namandla amakhulu, amathuba okuba khona kwebhethri ye-lithium iron phosphate kanye nebhethri ye-ternary lithium kuzoba kukhulu esikhathini esizayo, kunokuba ngubani ozothatha indawo yazo.

Kuyaqapheleka futhi ukuthi isidingo sesimo sesiteshi esingu-5g sizophinda senze isidingo sebhethri ye-lithium iron phosphate sikhuphuke kakhulu siye ku-10gwh, kanye nomthamo ofakiwe webhethri lamandla e-lithium iron phosphate ngo-2019 ngu-20.8gwh. Kulindeleke ukuthi isabelo semakethe se-lithium iron phosphate sikhule ngokushesha ngo-2020, sizuze ekwehlisweni kwezindleko kanye nokwenza ngcono ukuncintisana okulethwe ibhethri le-lithium iron.
