Chiyambi:
Pakadali pano, pali vuto lofala mu galimoto yatsopano yamagetsi ndipobatri ya lithiamumisika yosungiramo mphamvu, ndipo ndiko kuopa kuzizira. Palibe chifukwa china kupatula m'malo otentha kwambiri, magwiridwe antchito a mabatire a lithiamu amachepa kwambiri, kuwonetsa kutayika kwakukulu kwa mphamvu ndi mphamvu, zovuta zochaja, ndi zina zotero, kapena kulephera kugwira ntchito bwino.
Kumene kuli mavuto, palinso mwayi waukulu wopititsa patsogolo zinthu. Batire yapadera ya Xingdong Lithium Battery yotsika kutentha yapangidwira "kuzizira". Pa Ogasiti 8, pamsonkhano wa "2024 China Energy Storage Industry Ecological Conference" pa tsiku la 2024 World Battery and Energy Storage Industry Expo, Xingdong Lithium Battery idayambitsa mabatire anayi amphamvu kwambiri osagwirizana ndi kutentha kochepa omwe ali ndi mphamvu yayikulu yochapira komanso kutulutsa mphamvu yoposa 97%, zomwe zidapangitsa kuti mabatire a lithiamu iron phosphate asakhale otentha kwambiri komanso kuonetsetsa kuti mabatire a lithiamu iron phosphate amathanso kugwira ntchito bwino komanso mokhazikika nyengo yozizira.
Kodi mungatani kuti batire ya lithiamu isatenthe kwambiri?
"Pa kutentha kochepa, kuchuluka kwa mankhwala mkati mwa batri kumachepa ndipo liwiro la kayendedwe ka ma ayoni mu electrolyte limachepa, zomwe zimakhudzabatri ya lithiamumphamvu ya chaji ndi kutulutsa mphamvu. Kuphatikiza apo, kutentha kochepa kungayambitsenso kusintha kwa kapangidwe ka zinthu mkati mwa batri, zomwe zimakhudza magwiridwe antchito ndi moyo wa batri." Li Jia, purezidenti wa bizinesi yapadziko lonse ya Xingdong Lithium Battery, adati kuti athetse vuto la magwiridwe antchito otsika kutentha kwa mabatire, chofunikira ndikupanga zipangizo zomwe zimalekerera kutentha kochepa.
Kuyambira pa zipangizo ndi zina, Xingdong Lithium Battery yagonjetsa mavuto ndi kupanga bwino ukadaulo wopangidwa ndi patent. Yapanganso bwino kwambiri 4 low-temperaturemabatire a lithiamuzomwe zimatha kuchajidwa ndikutulutsidwa m'malo otentha pang'ono a -20℃, -25℃, -30℃, ndi -35℃, ndi mphamvu kuyambira 206Ah mpaka 314Ah, komanso mphamvu zofananira zochajidwa ndi kutulutsa mphamvu zopitilira 97%, 95%, 95%, ndi 90%, motsatana, zomwe zikutsogolera makampaniwa.
Ngati titayang'anitsitsa chinsinsichi, tidzapeza kuti kuphatikiza kwagolide kwa batri ya lithiamu ya Xingdong "4+N" kunali kofunikira kwambiri. 4 ikutanthauza ukadaulo waukulu anayi, ndipo N ikutanthauza ukadaulo wambiri wokhala ndi patent womwe umagwiritsidwa ntchito pamodzi:
1. Kudzera mu kuphatikiza kwa ma nanotubes a kaboni ndi graphene,batri ya lithiamuImpedance imachepa kwambiri, kukana kwamkati ndi ≤0.25mΩ, magwiridwe antchito amawonjezeka kwambiri, ndipo imatha kuthandizira 15C nthawi yomweyo yotulutsa mphamvu;
2. Ukadaulo wopaka diaphragm wokhala ndi patent umagwiritsidwa ntchito kuti upange chidutswa cha mtengo kukhala chogwirizana kwambiri panthawi yogwira ntchito, zomwe zimapangitsa kuti chitetezo cha batri chikhale bwino komanso magwiridwe antchito a nthawi yozungulira;
3. Electrolyte ya gel yomwe ili ndi patent imatengedwa, ndipo choyambitsa ndi cholumikizira chofanana ndi batire ya lithiamu iron phosphate zimawonjezedwa kuti batire ikhale yolimba kwambiri ku kutentha kochepa, ndipo kutentha kwa batire kumatha kufika -35℃ ~ 60℃;
4. Njira yopangira zinthu zambiri imagwiritsidwa ntchito, poyerekeza ndi njira yachikhalidwe yozungulira, kukana kwamkati kumachepetsedwa ndi 30%, ndi kukhazikika bwino kwa kapangidwe kake, chitetezo chapamwamba, moyo wautali wa kuzungulira, komanso kuchuluka kwa mphamvu ≥180Wh/kg;
5. Ndi ma patent 43 opanga zinthu zatsopano, dongosolo la lithiamu iron phosphate limatengedwa, kuphatikiza njira zapadera, ndipo kupanga kokha ndi mizere yolondola kwambiri zimagwiritsidwa ntchito kutsimikizira kuti maselo a batri ndi ofanana, ndipo zidzalimbikitsa kukweza ndi kubwerezabwereza kwa zinthu mosalekeza.
Zotsatira zake pamakampani opanga mabatire a lithiamu
Pa mlingo waukadaulo, mabatire ambiri pamsika pakadali pano amatha kugwira ntchito pamlingo wa kutentha wa -20℃ ~ 60℃, pomwe Xingdong Lithium Battery ndi kutentha kochepa.batri ya lithiamuimatha kugwira ntchito pa kutentha kwa -35℃～60℃, zomwe zingapangitse kuti pakhale kukweza ndi kupanga zatsopano kwa ukadaulo wa batri wotentha pang'ono ndikuyamba kutsogolera;
Pa mlingo wa mafakitale, Xingdong Lithium Battery imagwira ntchito mwakhama polimbana ndi vuto la mabatire otentha pang'ono ndipo imayambitsa zinthu zotsogola mumakampani. Pakati pawo, -35℃ kutentha kochepabatri ya lithiamuili ndi mphamvu yolipirira ndi kutulutsa mphamvu yoposa 90%, zomwe sizimangopanga phindu losiyana, komanso zikutanthauza kuti makampaniwa adzapezadi ufulu wofanana wamagetsi kumpoto ndi kum'mwera, kukhala chinthu china chofunikira kwambiri pakukula kwa ukadaulo wa batri;
Mu Pamsika, chimodzi mwa mavuto omwe akukumana nawo pakali pano ndi zida zankhondo zapamwamba kwambiri ndikuti pamene kutalika kwa ndege kukukwera, malo otentha pang'ono pamalo okwera kwambiri angayambitse kuchepa kwa magwiridwe antchito a batri; madera otentha pang'ono m'nyengo yozizira monga Inner Mongolia ndi Xinjiang akugwira ntchito molimbika kuti alimbikitse kumanga migodi yobiriwira; misika yakunja monga Europe ndi United States ili ndi nyengo yozizira kwambiri, kuthekera kosagwirizana ndi ma gridi, komanso mitengo yamagetsi yokwera. Anthu okhala m'deralo ayenera kufananiza njira zosungira mphamvu zotentha kwambiri kuti atsimikizire kuti magetsi amagwiritsidwa ntchito bwino m'nyengo yozizira...
Kufunika kwa msika kwa kutentha kochepa komwe kumagwira ntchito bwinomabatire a lithiamundi yofunika kwambiri, ndipo mabatire a Xingdong Lithium omwe amatentha pang'ono sangakwaniritse zosowa za momwe zinthu zilili pamwambapa, komanso apangidwa mochuluka ndipo angagwiritsidwe ntchito mwachangu.
Pa mlingo wochepetsa ndalama zobiriwira, pokhapokha ngati titayendetsa luso laukadaulo ndi luso la mafakitale, tingafulumizitse chitukuko cha kupanga zinthu zatsopano zabwino ndikukwaniritsa bwino zolinga za "dual carbon". Mabatire a Xingdong Lithium otsika kutentha amaswa malamulo ndipo angagwiritsidwe ntchito kwambiri popereka magetsi ku zida zolemera zaukadaulo, komanso kusungira mphamvu/mphamvu m'malo otentha pang'ono padziko lonse lapansi.
Mapeto
Ponseponse,makampani a batri a lithiamuakhala akuyankha mwachangu mavuto amsika, akusintha nthawi zonse ndikupambana, komanso akupereka njira zatsopano komanso zotsika mtengo zaukadaulo kwa omwe akufuna mabatire a lithiamu ogwira ntchito bwino. Kuyambira pazovuta zamakasitomala, amagwira ntchito molimbika kuti chitukuko chamakampani chikhale chokhazikika mtsogolo. Ichi ndi tanthauzo komanso chithumwa cha chitukuko chaukadaulo.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, chonde musazengereze kutifunsatitumizireni uthenga.
