Chiyambi:
Pakalipano, pali vuto lofala mu galimoto yatsopano yamagetsi ndilithiamu batiremisika yosungirako mphamvu, ndipo ndiko kuopa kuzizira. Popanda chifukwa china kusiyana ndi malo otsika kutentha, ntchito ya mabatire a lithiamu imachepetsedwa kwambiri, kusonyeza kutayika kwakukulu kwa mphamvu ndi mphamvu, zovuta zolipiritsa, etc., kapena ngakhale kulephera kugwira ntchito bwino.
Kumene kuli malo opweteka, palinso mwayi waukulu wa chitukuko. Battery yapadera ya Xingdong Lithium Battery yotsika kwambiri idapangidwira "ozizira". Pa Ogasiti 8, pamwambo wa "2024 China Energy Storage Industry Ecological Conference" pa tsiku la 2024 World Battery and Energy Storage Industry Expo, Xingdong Lithium Battery idakhazikitsa mabatire anayi osamva kutentha kwambiri omwe ali ndi mtengo wokwanira komanso kutulutsa bwino. opitilira 97%, omwe adapanga zophophonya zotsika kutentha kwa mabatire a lithiamu iron phosphate ndikuwonetsetsa kuti mabatire a lithiamu iron phosphate amathanso kugwira ntchito mokhazikika komanso moyenera nyengo yozizira.
Momwe mungagonjetsere kutentha kwa lithiamu batire?
"Pansi pa kutentha kochepa, mphamvu ya mankhwala mkati mwa batire imachepa ndipo kuthamanga kwa ma ion mu electrolyte kumachepa, zomwe zimakhudzalithiamu batirekulipira ndi kutulutsa bwino. Kuphatikiza apo, kutentha pang'ono kungayambitsenso kusintha kwa zinthu mkati mwa batire, motero kusokoneza magwiridwe antchito ndi moyo wa batri." Li Jia, purezidenti wa bizinesi yapadziko lonse ya Xingdong Lithium Battery, adanena kuti kuthetsa vuto la kutentha kwa batire. , chinsinsi ndi kupanga zipangizo zolekerera kutentha kochepa.
Kuyambira pazida ndi zina, Battery ya Lithium ya Xingdong yagonjetsa zovuta ndikupanga bwino matekinoloje angapo ovomerezeka. Yapanganso bwino kwambiri 4 kutentha kochepamabatire a lithiamuyomwe imatha kulipitsidwa ndikutulutsidwa m'malo otentha otsika a -20 ℃, -25 ℃, -30 ℃, ndi -35 ℃, okhala ndi 206Ah mpaka 314Ah, komanso mphamvu zofananira ndi zotulutsa zokulirapo kuposa 97%, 95 %, 95%, ndi 90%, motero, kutsogolera makampani.
Tikayang'anitsitsa chinsinsicho, tipeza kuti kuphatikiza kwagolide kwa Xingdong lithiamu batire "4+N" kunatenga gawo lofunika kwambiri. 4 imatanthawuza matekinoloje anayi oyambira, ndipo N imatanthawuza matekinoloje angapo omwe amagwiritsidwa ntchito kuphatikiza:
1. Kupyolera mu kuphatikiza kwa carbon nanotubes ndi graphene, ndilithiamu batirekutsekereza kumachepetsedwa kwambiri, kukana kwamkati ndi ≤0.25mΩ, magwiridwe antchito amakula bwino, ndipo amatha kuthandizira 15C kutulutsa nthawi yomweyo;
2. Ukadaulo wopaka patenti wa diaphragm umatengedwa kuti upangitse kuti chidutswacho chikhale chomangika kwambiri panthawi yogwira ntchito, kuwongolera bwino chitetezo cha batri ndi magwiridwe antchito;
3. The patented in-situ gel electrolyte imatengedwa, ndipo choyambitsa ndi coagulant chofananira ndi batri ya lithiamu iron phosphate imawonjezedwa kuti batire ikhale yolimbana ndi kutentha kochepa, ndipo kutentha kwa batire kumatha kufika -35℃～60℃;
4. Njira yopangira ma stacking imatengedwa, poyerekeza ndi njira yachikhalidwe yokhotakhota, kukana kwamkati kumachepetsedwa ndi 30%, ndi kukhazikika kwapangidwe bwino, chitetezo chapamwamba, moyo wautali wautali, ndi mphamvu zowonongeka ≥180Wh / kg;
5. Ndi ma patent opangidwa ndi 43, dongosolo la lithiamu iron phosphate limatengedwa, kuphatikizidwa ndi njira zapadera, ndipo mizere yodziwikiratu yodziwikiratu komanso mizere yolondola kwambiri imagwiritsidwa ntchito kuwonetsetsa kuti ma cell a batri amagwirizana kwambiri, ndipo adzalimbikitsa kukweza kosalekeza ndi kubwereza kwa mankhwala.
Zotsatira pamakampani a batri la lithiamu
Pamlingo waukadaulo, mabatire ambiri pamsika amatha kugwira ntchito pamlingo wa -20 ℃ ~ 60 ℃, pomwe kutentha kwa Xingdong Lithium Battery kutsika.lithiamu batireimatha kugwira ntchito pa kutentha kwa -35 ℃～60 ℃, yomwe imayenera kulimbikitsa kukweza ndi kukonzanso ukadaulo wa batri wocheperako ndikuwongoleranso;
Pamsika wamakampani, Battery ya Lithium ya Xingdong imalimbana mwachangu ndi vuto la mabatire otsika kutentha ndikuyambitsa zinthu zotsogola m'makampani. Pakati pawo, -35 ℃ otsika kutenthalithiamu batireali ndi malipiro ndi kutulutsa mphamvu zoposa 90%, zomwe sizimangopanga phindu losiyanitsidwa, komanso zikutanthauza kuti makampaniwa adzakwaniritsadi ufulu wofanana wa mphamvu kumpoto ndi kum'mwera, kukhala chinthu china chofunika kwambiri pa chitukuko cha teknoloji ya batri;
Mumsika wamsika, chimodzi mwa zovuta zomwe zikukumana nazo panopa ndi zida zankhondo zapamwamba kwambiri ndikuti pamene kukwera kwa ndege kumawonjezeka, malo otsika kwambiri a kutentha pamtunda angapangitse kuti ntchito ya batri ikhale yochepa; madera otsika kutentha m'nyengo yozizira monga Inner Mongolia ndi Xinjiang akugwira ntchito mwakhama kuti alimbikitse kumanga migodi yobiriwira; Misika yakunja monga Europe ndi United States ili ndi nyengo yozizira kwambiri, kuthekera kolumikizana ndi gridi yofooka, komanso mitengo yamagetsi yokwera. Anthu okhalamo ayenera kufananiza njira zosungiramo mphamvu zochepetsera kutentha kuti zitsimikizire kugwiritsa ntchito magetsi mokhazikika m'nyengo yozizira ...
Kufuna msika kwa mkulu-ntchito otsika kutenthamabatire a lithiamundizofunikira kwambiri, ndipo mabatire otsika kwambiri a Xingdong Lithium sangangokwaniritsa zofunikira zazomwe tatchulazi, komanso apangidwa mochuluka ndipo atha kugwiritsidwa ntchito mwachangu.
Pamlingo wochepetsera mtengo wobiriwira, pokha poyendetsa luso laukadaulo komanso luso la mafakitale titha kufulumizitsa chitukuko cha zokolola zatsopano ndikukwaniritsa zolinga za "carbon wapawiri". Mabatire otsika kwambiri a Xingdong Lithium amaphwanya zoletsa ndipo amatha kugwiritsidwa ntchito kwambiri popangira magetsi pazida zolemera zamainjiniya, komanso kusungirako mphamvu / mphamvu m'madera otsika kutentha padziko lonse lapansi.
Mapeto
Zonse,makampani a lithiamu batireakhala akuyankha mwachangu ku zovuta zamsika, kuwongolera nthawi zonse ndikudumphadumpha, ndikupereka njira zatsopano komanso zotsika mtengo zaukadaulo kwa omwe akufunafuna batire ya lithiamu. Kuyambira malo opweteka a makasitomala, amagwira ntchito mwakhama kuti apititse patsogolo chitukuko chokhazikika chamakampani mtsogolomu. Ichinso ndi tanthauzo ndi chithumwa cha chitukuko cha zamakono.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, musazengereze kuterokufikira kwa ife.
