Mtengo wokwera wa zipangizo zopangira ternary udzakhudzanso kukwezedwa kwa mabatire a ternary lithium. Cobalt ndiye mabatire amphamvu okwera mtengo kwambiri achitsulo. Pambuyo podulidwa kangapo, avareji ya electrolytic cobalt pa tani iliyonse ndi pafupifupi 280000 yuan. Zipangizo zopangira za lithiamu iron phosphate zili ndi phosphorous ndi chitsulo chochuluka, kotero mtengo wake ndi wosavuta kuwongolera. Chifukwa chake, ngakhale batire ya ternary lithium imatha kusintha kwambiri magalimoto atsopano amphamvu, pofuna chitetezo ndi mtengo, opanga sanasiye kafukufuku waukadaulo ndi chitukuko cha batire ya lithiamu iron phosphate.

Chaka chatha, Ningde era idatulutsa ukadaulo wa CTP (kutengera pakiti). Malinga ndi deta yomwe idatulutsidwa ndi Ningde times, CTP ikhoza kuwonjezera kuchuluka kwa magwiritsidwe ntchito a batri ndi 15%-20%, kuchepetsa kuchuluka kwa zida za batri ndi 40%, kuwonjezera mphamvu yopangira ndi 50%, ndikuwonjezera kuchuluka kwa mphamvu ya batri ndi 10%-15%. Pa CTP, mabizinesi akunyumba monga BAIC new energy (EU5), Weilai automobile (ES6), Weima automobile ndi Nezha automobile awonetsa kuti agwiritsa ntchito ukadaulo wa nthawi ya Ningde. VDL, kampani yopanga mabasi ku Europe, idatinso idzayambitsa izi mkati mwa chaka chino.

Malinga ndi chizolowezi chotsika kwa ndalama zothandizira magalimoto atsopano amphamvu, poyerekeza ndi makina a batri a lithiamu a 3 yuan omwe ali ndi mtengo wa pafupifupi 0.8 yuan /wh, mtengo wapano wa 0.65 yuan /wh wa makina a lithiamu iron phosphate ndi wopindulitsa kwambiri, makamaka pambuyo pa kusinthidwa kwaukadaulo, batri ya lithiamu iron phosphate tsopano ikhoza kuwonjezera mtunda wa magalimoto kufika pafupifupi 400 km, kotero yayamba kukopa chidwi cha mabizinesi ambiri a magalimoto. Deta ikuwonetsa kuti kumapeto kwa nthawi yosinthira ndalama zothandizira mu Julayi 2019, mphamvu yoyikidwa ya lithiamu iron phosphate ndi 48.8% kuchokera pa 21.2% mu Ogasiti mpaka 48.8% mu Disembala.

Tesla, mtsogoleri wa makampani omwe akhala akugwiritsa ntchito mabatire a lithiamu-ion kwa zaka zambiri, tsopano ayenera kuchepetsa ndalama zake. Malinga ndi dongosolo latsopano la 2020 la ndalama zothandizira magalimoto amphamvu, ma tram osasinthana omwe ali ndi ma yuan opitilira 300000 sangalandire ndalama zothandizira. Izi zidapangitsa Tesla kuganizira zofulumizitsa njira yosinthira mtundu wachitatu kupita ku ukadaulo wa batire wa lithiamu iron phosphate. Posachedwapa, CEO wa Tesla musk adati pamsonkhano wake wotsatira wa "tsiku la batire", adzayang'ana kwambiri mfundo ziwiri, imodzi ndi ukadaulo wa batire wochita bwino kwambiri, inayo ndi batire yopanda cobalt. Nkhaniyo itangotuluka, mitengo ya cobalt yapadziko lonse idatsika.

Zanenedwanso kuti nthawi ya Tesla ndi Ningde ikukambirana za mgwirizano wa mabatire otsika a cobalt kapena osakhala a cobalt, ndipo lithiamu iron phosphate ikhoza kukwaniritsa zosowa za chitsanzo choyambira 3. Malinga ndi Unduna wa Zamalonda ndi Ukadaulo wa Chidziwitso, kutalika kwa mtunda wa chitsanzo choyambira 3 ndi pafupifupi 450km, kuchuluka kwa mphamvu ya dongosolo la batri ndi pafupifupi 140-150wh / kg, ndipo mphamvu yonse yamagetsi ndi pafupifupi 52kwh. Pakadali pano, magetsi omwe amaperekedwa ndi nthawi ya Ningde amatha kupanga 80% mu mphindi 15, ndipo kuchuluka kwa mphamvu ya paketi ya batri yokhala ndi kapangidwe kopepuka kumatha kufika 155wh / kg, zomwe ndizokwanira kukwaniritsa zofunikira zomwe zili pamwambapa. Akatswiri ena amati ngati Tesla igwiritsa ntchito batire yachitsulo ya lithiamu, mtengo wa batire imodzi ukuyembekezeka kuchepetsa 7000-9000 yuan. Komabe, Tesla anayankha kuti mabatire opanda cobalt satanthauza mabatire a lithiamu iron phosphate.

Kuwonjezera pa phindu la mtengo, kuchuluka kwa mphamvu ya batire ya lithiamu iron phosphate ikafika padenga laukadaulo kwawonjezeka. Kumapeto kwa Marichi chaka chino, BYD idatulutsa batire yake ya blade, yomwe idati kuchuluka kwa mphamvu yake kunali kokwera pafupifupi 50% kuposa batire yachikhalidwe yachitsulo pamlingo womwewo. Kuphatikiza apo, poyerekeza ndi batire yachikhalidwe ya lithiamu iron phosphate, mtengo wa batire ya blade umachepetsedwa ndi 20% - 30%.

Batire yotchedwa blade kwenikweni ndi ukadaulo wopititsa patsogolo kugwira ntchito bwino kwa batire powonjezera kutalika kwa selo ndikupangitsa kuti selo likhale losalala. Chifukwa selo limodzi ndi lalitali komanso lathyathyathya, limatchedwa "blade". Zikumveka kuti mitundu yatsopano ya magalimoto amagetsi a BYD idzagwiritsa ntchito ukadaulo wa "batire la blade" chaka chino ndi chamawa.

Posachedwapa, Unduna wa Zachuma, Unduna wa Zamakampani ndi Ukadaulo wa Chidziwitso, Unduna wa Sayansi ndi Ukadaulo, ndi National Development and Reform Commission pamodzi adapereka chidziwitso chokhudza kusintha ndikusintha mfundo zothandizira magalimoto atsopano amphamvu, zomwe zidawonetsa momveka bwino kuti njira yoyendetsera magalimoto apagulu ndi magetsi m'magawo enaake iyenera kufulumizitsidwa, ndipo chitetezo ndi ubwino wa lithiamu iron phosphate zikuyembekezeka kupititsidwa patsogolo. Zingathe kunenedweratu kuti ndi kufulumira pang'onopang'ono kwa kuthamanga kwa magetsi komanso kusintha kosalekeza kwa ukadaulo wokhudzana ndi chitetezo cha mabatire ndi kuchuluka kwa mphamvu, kuthekera kokhala pamodzi kwa batire ya lithiamu iron phosphate ndi batire ya lithiamu ternary kudzakhala kwakukulu mtsogolo, m'malo mongowalowetsa m'malo mwake.

Ndikofunikanso kudziwa kuti kufunikira kwa batri ya lithiamu iron phosphate kukwera kwambiri kufika pa 10gwh, ndipo mphamvu yokhazikika ya batri ya lithiamu iron phosphate mu 2019 ndi 20.8gwh. Akuyembekezeka kuti gawo la msika wa lithiamu iron phosphate lidzakwera mofulumira mu 2020, kupindula ndi kuchepetsa ndalama ndi kusintha kwa mpikisano komwe kumabwera chifukwa cha batri ya lithiamu iron.
