Izindleko eziphezulu zezinto zokusetshenziswa zezinto ze-ternary nazo zizoba nomthelela omubi ekuthuthukisweni kwamabhethri e-ternary lithium. I-Cobalt iyinsimbi ebiza kakhulu kumabhethri kagesi. Ngemva kokusika okuningana, isilinganiso samanje se-electrolytic cobalt ngethani singaba ngu-280000 yuan. Izinto zokusetshenziswa zebhethri le-lithium iron phosphate zicebile nge-phosphorus ne-iron, ngakho-ke izindleko kulula ukuzilawula. Ngakho-ke, yize ibhethri le-ternary lithium lingathuthukisa kakhulu uhla lwezimoto ezintsha zamandla, ngenxa yokuphepha kanye nokucabangela izindleko, abakhiqizi abazange babeke phansi ucwaningo lobuchwepheshe kanye nokuthuthukiswa kwebhethri le-lithium iron phosphate.

Ngonyaka odlule, i-Ningde era ikhiphe ubuchwepheshe be-CTP (ukuya kuseli) . Ngokusho kwedatha ekhishwe yi-Ningde times, i-CTP ingakhuphula izinga lokusetshenziswa kwevolumu yephakethe lebhethri ngo-15%-20%, inciphise inani lezingxenye zephakethe lebhethri ngo-40%, ikhuphule ukusebenza kahle kokukhiqiza ngo-50%, futhi ikhuphule ubuningi bamandla ephakethe lebhethri ngo-10%-15%. Ku-CTP, amabhizinisi asekhaya afana ne-BAIC new energy (EU5), i-Weilai automobile (ES6), i-Weima automobile kanye ne-Nezha automobile abonise ukuthi azosebenzisa ubuchwepheshe besikhathi se-Ningde. I-VDL, umenzi wamabhasi waseYurophu, nayo ithe izoyethula phakathi nonyaka.

Ngaphansi komkhuba wokwehla kwezibonelelo zezimoto ezintsha zamandla, uma kuqhathaniswa nohlelo lwebhethri le-lithium elingu-3 yuan olunezindleko ezingaba ngu-0.8 yuan /wh, intengo yamanje engu-0.65 yuan /wh yohlelo lwe-lithium iron phosphate inenzuzo enkulu, ikakhulukazi ngemuva kokuthuthukiswa kobuchwepheshe, ibhethri le-lithium iron phosphate manje lingandisa futhi ibanga lemoto libe cishe ngamakhilomitha angu-400, ngakho-ke seliqalile ukuheha ukunaka kwamabhizinisi amaningi ezimoto. Idatha ikhombisa ukuthi ekupheleni kwesikhathi sokushintsha kwezibonelelo ngoJulayi 2019, amandla afakiwe e-lithium iron phosphate alinganiselwa ku-48.8% kusukela ku-21.2% ngo-Agasti kuya ku-48.8% ngoDisemba.

I-Tesla, umholi wemboni obesebenzisa amabhethri e-lithium-ion iminyaka eminingi, manje kufanele yehlise izindleko zayo. Ngokusho kohlelo lokuxhaswa kwezimoto ezintsha zamandla luka-2020, amamodeli e-tram angashintshisani anama-yuan angaphezu kuka-300000 awakwazi ukuthola uxhaso. Lokhu kwashukumisela i-Tesla ukuthi icabangele ukusheshisa inqubo yokushintshela kwemodeli 3 kubuchwepheshe bebhethri le-lithium iron phosphate. Muva nje, i-CEO ye-Tesla uMusk uthe engqungqutheleni yakhe elandelayo "yosuku lwebhethri", uzogxila emaphuzwini amabili, elilodwa ubuchwepheshe bebhethri obusebenza kahle kakhulu, elinye ibhethri elingenayo i-cobalt. Lapho nje izindaba ziphuma, amanani e-cobalt aphesheya kwezilwandle ehla.

Kubikwa nokuthi isikhathi seTesla neseNingde sixoxa ngokubambisana kwamabhethri e-cobalt aphansi noma angewona ama-cobalt, kanti i-lithium iron phosphate ingahlangabezana nezidingo zemodeli eyisisekelo 3. Ngokusho koMnyango Wezimboni Nobuchwepheshe Bolwazi, ibanga lokukhuthazela lemodeli eyisisekelo 3 lingamakhilomitha angama-450, ubukhulu bamandla besistimu yebhethri bungamakhilomitha angama-140-150wh / kg, kanti umthamo kagesi uwonke ungamakhilomitha angama-52kwh. Njengamanje, ukunikezwa kwamandla okuhlinzekwa yi-Ningde era kungenza kufike ku-80% ngemizuzu eyi-15, kanti ubukhulu bamandla bephakethe lebhethri elinomklamo olula bungafinyelela ku-155wh / kg, okwanele ukuhlangabezana nezidingo ezingenhla. Abanye abahlaziyi bathi uma iTesla isebenzisa ibhethri le-lithium iron, izindleko zebhethri elilodwa kulindeleke ukuthi zehlise ama-yuan angama-7000-9000. Kodwa-ke, iTesla iphendule ngokuthi amabhethri angenayo i-cobalt akusho ukuthi amabhethri e-lithium iron phosphate.

Ngaphezu kwenzuzo yezindleko, ubuningi bamandla ebhethri le-lithium iron phosphate uma selifinyelele ophahleni lobuchwepheshe bukhuphukile. Ekupheleni kukaMashi kulo nyaka, i-BYD ikhiphe ibhethri layo le-blade, elithe ubuningi bamandla alo buphakeme cishe ngo-50% kunebhethri le-iron lendabuko ngobuningi obufanayo. Ngaphezu kwalokho, uma kuqhathaniswa nebhethri le-lithium iron phosphate lendabuko, izindleko zebhethri le-blade zincishiswe ngo-20% - 30%.

Ibhethri okuthiwa i-blade empeleni ubuchwepheshe bokuthuthukisa ukusebenza kahle kokuhlanganiswa kwephakethe lebhethri ngokwandisa ubude beseli nokwenza iseli libe yi-flat. Ngenxa yokuthi iseli elilodwa lide futhi liyisicaba, libizwa ngokuthi “blade”. Kuyaqondakala ukuthi amamodeli amasha ezimoto zikagesi ze-BYD azosebenzisa ubuchwepheshe “bebhethri le-blade” kulo nyaka nakulo nyaka ozayo.

Muva nje, uMnyango Wezezimali, uMnyango Wezimboni Nobuchwepheshe Bolwazi, uMnyango Wezesayensi Nobuchwepheshe, kanye neKhomishini Yentuthuko Nokuguqulwa Kazwelonke bakhiphe isaziso ngokuhlanganyela mayelana nokulungisa nokuthuthukisa inqubomgomo yoxhaso lwezimoto ezintsha zamandla, okwakwenza kwacaca ukuthi inqubo yezokuthutha zomphakathi kanye nokufakwa kukagesi ezimotweni emikhakheni ethile kufanele isheshiswe, futhi izinzuzo zokuphepha kanye nezindleko ze-lithium iron phosphate kulindeleke ukuthi zithuthukiswe. Kungabikezelwa ukuthi ngokusheshisa kancane kancane kwejubane lokufakwa kukagesi kanye nokuthuthukiswa okuqhubekayo kobuchwepheshe obuhlobene bokuphepha kwebhethri kanye nobuningi bamandla, amathuba okuba khona kwebhethri le-lithium iron phosphate kanye nebhethri le-lithium eliyi-ternary kuzoba makhulu esikhathini esizayo, kunokuba ubani ozolithatha indawo.

Kuyafaneleka futhi ukuqaphela ukuthi isidingo esimeni sesiteshi esiyisisekelo esingu-5g sizokwenza isidingo sebhethri le-lithium iron phosphate sikhuphuke kakhulu sifinyelele ku-10gwh, kanti umthamo ofakiwe webhethri lamandla le-lithium iron phosphate ngo-2019 ungama-20.8gwh. Kulindeleke ukuthi isabelo semakethe se-lithium iron phosphate sizokhula ngokushesha ngo-2020, sizuze ekunciphiseni izindleko kanye nokuthuthukiswa kokuncintisana okulethwa yibhethri le-lithium iron.
