Kukwera mtengo kwazinthu zopangira zida za ternary kudzakhalanso ndi vuto pakulimbikitsa mabatire a ternary lithiamu. Cobalt ndiye chitsulo chokwera mtengo kwambiri pamabatire amphamvu. Pambuyo mabala angapo, pafupifupi panopa electrolytic cobalt pa tani pafupifupi 280000 yuan. The zopangira lithiamu chitsulo mankwala batire ndi wolemera phosphorous ndi chitsulo, kotero mtengo ndi zosavuta kulamulira. Choncho, ngakhale ternary lifiyamu batire akhoza kwambiri kusintha osiyanasiyana magalimoto mphamvu zatsopano, chifukwa chitetezo ndi kuganizira mtengo, opanga sanaike pansi kafukufuku luso ndi chitukuko cha batire lifiyamu chitsulo mankwala.

Chaka chatha, nthawi ya Ningde idatulutsa ukadaulo wa CTP (cell to pack). Malinga ndi zomwe zatulutsidwa ndi nthawi za Ningde, CTP imatha kuonjezera kuchuluka kwa magwiritsidwe ntchito a batri ndi 15% -20%, kuchepetsa kuchuluka kwa batire ndi 40%, kuonjezera kupanga bwino ndi 50%, ndikuwonjezera kachulukidwe wamagetsi a batri ndi 10% -15%. Kwa CTP, mabizinesi apakhomo monga BAIC new energy (EU5), Weilai automobile (ES6), Weima galimoto ndi Nezha magalimoto awonetsa kuti atengera ukadaulo wa nthawi ya Ningde. VDL, wopanga mabasi ku Europe, adatinso iziyambitsa chaka chino.

Pansi pa kutsika kwa ndalama zothandizira magalimoto amagetsi atsopano, poyerekeza ndi 3 yuan lithiamu batire yamagetsi yomwe ili ndi mtengo wa pafupifupi 0,8 yuan / wh, mtengo wapano wa 0,65 yuan / wh wa lithiamu iron phosphate system ndiwopindulitsa kwambiri, makamaka pambuyo pakukweza luso, batire ya lithiamu iron phosphate imathanso kukulitsa chidwi chagalimoto chomwe chili ndi 400 km kukopa chidwi chagalimoto. mabizinesi. Deta ikuwonetsa kuti kumapeto kwa nthawi yosinthira ndalama mu Julayi 2019, kuchuluka kwa lithiamu iron phosphate kumakhala 48.8% kuchokera 21.2% mu Ogasiti mpaka 48.8% mu Disembala.

Tesla, mtsogoleri wamakampani omwe wakhala akugwiritsa ntchito mabatire a lithiamu-ion kwa zaka zambiri, tsopano akuyenera kuchepetsa ndalama zake. Malinga ndi chiwembu chatsopano cha 2020 chothandizira magalimoto atsopano, ma tram osasinthana omwe ali ndi ma yuan opitilira 300000 sangalandire thandizo. Izi zidapangitsa Tesla kuganizira zofulumizitsa njira ya 3 yosinthira kuukadaulo wa batri wa lithiamu iron phosphate. Posachedwapa, Tesla CEO musk adanena kuti pamsonkhano wake wotsatira wa "tsiku la batri", adzayang'ana pa mfundo ziwiri, imodzi ndi teknoloji ya batri yapamwamba, ina ndi batri ya cobalt yaulere. Nkhaniyo itangotuluka, mitengo ya cobalt yapadziko lonse idatsika.

Amanenanso kuti Tesla ndi Ningde nthawi akukambirana mgwirizano wa otsika cobalt kapena sanali cobalt mabatire, ndi lifiyamu chitsulo mankwala akhoza kukwaniritsa zofunika chitsanzo chitsanzo 3. Malinga ndi Utumiki wa mafakitale ndi zamakono zamakono, kupirira mtunda wa chitsanzo zofunika 3 ndi za 450km, kachulukidwe mphamvu ya batire dongosolo makilogalamu 150wh ndi pafupifupi 150wh / electric mphamvu pafupifupi 140 52kw pa. Pakali pano, magetsi operekedwa ndi nthawi ya Ningde amatha kufika 80% mu mphindi 15, ndipo kachulukidwe kake ka batri kamangidwe kamene kamakhala kopepuka kumatha kufika 155wh / kg, yomwe ndi yokwanira kukwaniritsa zomwe zili pamwambazi. Akatswiri ena amanena kuti ngati Tesla amagwiritsa ntchito lithiamu chitsulo batire, mtengo wa batire limodzi akuyembekezeka kuchepetsa 7000-9000 yuan. Komabe, Tesla adayankha kuti mabatire aulere a cobalt samatanthawuza mabatire a lithiamu iron phosphate.

Kuphatikiza pa mtengo wamtengo wapatali, kuchulukitsitsa kwamphamvu kwa batri ya lithiamu iron phosphate ikangofika padenga laukadaulo kwawonjezeka. Kumapeto kwa Marichi chaka chino, BYD idatulutsa batire yake yamasamba, yomwe idati kachulukidwe ake amphamvu anali pafupifupi 50% kuposa batire yachitsulo yachikhalidwe pa voliyumu yomweyo. Kuphatikiza apo, poyerekeza ndi batire yachikhalidwe ya lithiamu iron phosphate battery, mtengo wa batire la blade umachepetsedwa ndi 20% - 30%.

Chomwe chimatchedwa blade batire kwenikweni ndi ukadaulo wopititsa patsogolo luso la kuphatikiza kwa paketi ya batri powonjezera kutalika kwa cell ndikuwongolera cell. Chifukwa selo limodzi ndi lalitali komanso lathyathyathya, limatchedwa "tsamba". Zikumveka kuti mitundu yatsopano yagalimoto yamagetsi ya BYD idzatengera ukadaulo wa "batire latsamba" chaka chino komanso chotsatira.

Posachedwapa, Unduna wa Zachuma, Unduna wa zamakampani ndi ukadaulo wazidziwitso, Unduna wa Sayansi ndi Umisiri, ndi National Development and Reform Commission ogwirizana adapereka chidziwitso pakusintha ndikuwongolera malamulo a subsidy kwa magalimoto amagetsi atsopano, zomwe zidawonetsa kuti njira zoyendera anthu onse ndi magetsi agalimoto m'magawo enaake ziyenera kufulumizitsidwa, ndipo chitetezo ndi mtengo wabwino wa lifiyamu chitsulo phosphate chimayembekezeredwa. Iwo akhoza ananeneratu kuti ndi mathamangitsidwe wapang'onopang'ono wa mayendedwe a magetsi ndi mosalekeza kusintha kwa matekinoloje okhudzana ndi chitetezo batire ndi kachulukidwe mphamvu, kuthekera kukhala limodzi lifiyamu chitsulo mankwala batire ndi ternary lithiamu batire adzakhala wamkulu m'tsogolo, osati amene m'malo mwawo.

Ndizofunikiranso kudziwa kuti kufunikira kwa 5g base station station kupangitsanso kufunikira kwa batire ya lithiamu iron phosphate kukwera kwambiri mpaka 10gwh, komanso mphamvu yoyika ya lithiamu iron phosphate power battery mu 2019 ndi 20.8gwh. Akuyembekezeka kuti msika wa lithiamu iron phosphate uchulukirachulukira mu 2020, kupindula ndi kuchepetsa mtengo komanso kuwongolera mpikisano komwe kumabwera ndi batri yachitsulo ya lithiamu.
