Kukwera kwa Mabatire Olimba a State: Kutsegula Nyengo Yatsopano Yosungirako Mphamvu

Kupambana kwaukadaulo wa Battery wa Solid State
Makampani opanga mabatire olimba kwambiri atsala pang'ono kusintha kwambiri, pomwe makampani angapo akupita patsogolo kwambiri paukadaulo, kukopa chidwi cha osunga ndalama ndi ogula. Ukadaulo wotsogola wa batirewu umagwiritsa ntchito ma electrolyte olimba m'malo mwa ma electrolyte amadzimadzi azikhalidwe zamabatire a lithiamu-ion ndipo akuyembekezeka kusintha njira zosungira mphamvu m'magawo osiyanasiyana, makamaka magalimoto amagetsi (EVs).

Pamsonkhano wachiwiri wa China All-Solid State Battery Innovation and Development Summit Forum womwe unachitikira pa February 15, Shenzhen.BYDLithium Battery Co., Ltd. yalengeza mapulani ake amtsogolo olimba a batri. BYD CTO Sun Huajun adanena kuti kampaniyo ikukonzekera kuyambitsa kuwonetsera kwakukulu kwa mabatire amtundu uliwonse mu 2027 ndikukwaniritsa ntchito zazikulu zamalonda pambuyo pa 2030. Ndandanda yokhumba iyi imasonyeza kuti anthu akudalira kwambiri teknoloji yolimba komanso kuthekera kwake kukonzanso malo a mphamvu.

Kuphatikiza pa BYD, makampani opanga nzeru monga Qingtao Energy ndi NIO New Energy alengezanso mapulani opangira mabatire olimba kwambiri. Nkhaniyi ikuwonetsa kuti makampani opanga makampani akupikisana kuti apange ndikugwiritsa ntchito ukadaulo wapamwambawu, kupanga gulu limodzi. Kuphatikiza kwa R&D ndikukonzekera msika kukuwonetsa kuti mabatire olimba akuyembekezeka kukhala yankho lalikulu posachedwa.

Ubwino wa mabatire olimba
Ubwino wa mabatire olimba ndi ambiri komanso okakamiza, zomwe zimawapangitsa kukhala njira yabwino yosinthira mabatire amtundu wa lithiamu-ion. Chimodzi mwazabwino kwambiri ndi chitetezo chawo chachikulu. Mosiyana ndi mabatire achikhalidwe omwe amagwiritsa ntchito ma electrolyte amadzi oyaka, mabatire olimba a boma amagwiritsa ntchito ma elekitirodi olimba, omwe amachepetsa kwambiri chiopsezo cha kutayikira ndi moto. Chitetezo chokhazikikachi ndi chofunikira kwambiri pamagalimoto amagetsi, pomwe chitetezo cha batri ndichofunika kwambiri.

Ubwino winanso waukulu ndi kuchuluka kwamphamvu kwamagetsi komwe mabatire olimba atha kukwaniritsa. Izi zikutanthauza kuti akhoza kusunga mphamvu zambiri kuposa mabatire achikhalidwe mu voliyumu imodzi kapena kulemera kwake. Zotsatira zake, magalimoto amagetsi okhala ndi mabatire olimba amatha kupereka nthawi yayitali yoyendetsa, kuthana ndi nkhawa imodzi yomwe ogula amakhala nayo pakutengera magalimoto amagetsi. Kutalikitsa moyo wa batri sikuti kumangowonjezera luso la wogwiritsa ntchito, komanso kumapangitsa kuti mphamvu zonse ziziyenda bwino.

Kuphatikiza apo, zinthu zamabatire olimba-boma zimawapatsa moyo wautali wozungulira, womwe umachepetsa kuwonongeka kwa electrolyte pakulipiritsa ndi kutulutsa. Kukhala ndi moyo wautali kumatanthauza kutsika mtengo pakapita nthawi chifukwa ogula safunikira kusintha mabatire pafupipafupi. Kuonjezera apo, mabatire olimba kwambiri amagwira ntchito modalirika pa kutentha kwakukulu, kuwapangitsa kukhala oyenerera ntchito zosiyanasiyana kuchokera kumagetsi ogula magetsi kupita ku magalimoto amagetsi omwe amagwira ntchito m'madera ovuta kwambiri.

Kulipiritsa mwachangu komanso zopindulitsa zachilengedwe
Kutha kulipira mwachangu kwa mabatire olimba ndi mwayi wina wofunikira womwe umawasiyanitsa ndi ukadaulo wamba wa batri. Chifukwa cha kuchuluka kwa ma ionic conductivity, mabatire awa amatha kulipiritsidwa mwachangu, zomwe zimapangitsa ogwiritsa ntchito kuti azikhala ndi nthawi yochepa akudikirira kuti zida zawo kapena magalimoto azilipiritsa. Izi ndizowoneka bwino kwambiri pamagalimoto amagetsi, chifukwa nthawi yocheperako imatha kupangitsa kuti eni ake agalimoto yamagetsi azikhala osavuta komanso ochita bwino.

Kuphatikiza apo, mabatire olimba-boma ndi okonda zachilengedwe kuposa mabatire a lithiamu-ion. Mabatire olimba amagwiritsira ntchito zipangizo zochokera kuzinthu zokhazikika, kuchepetsa kudalira zitsulo zosowa, zomwe nthawi zambiri zimagwirizanitsidwa ndi kuwonongeka kwa chilengedwe ndi nkhani zamakhalidwe. Pamene dziko likugogomezera kwambiri kukhazikika, kukhazikitsidwa kwa ukadaulo wa batri wokhazikika kumagwirizana ndi zoyesayesa zapadziko lonse lapansi zopanga njira zothetsera mphamvu zobiriwira.

Mwachidule, makampani opanga mabatire olimba kwambiri ali pachiwopsezo chachikulu, ndikupita patsogolo kwaukadaulo komwe kukutsegulira njira yatsopano yosungira mphamvu. Makampani monga BYD, Qingtao Energy, ndi Weilan New Energy akutsogolera, akuwonetsa kuthekera kwa mabatire olimba kuti asinthe msika wamagalimoto amagetsi ndi kupitilira apo. Ndi zabwino zambiri monga chitetezo chowonjezereka, kuchulukitsidwa kwamphamvu kwamphamvu, moyo wautali wozungulira, kuthamangitsa mwachangu, komanso zopindulitsa zachilengedwe, mabatire olimba amathandizira kwambiri m'tsogolo posungirako ndikugwiritsa ntchito mphamvu. Pamene makampaniwa akupitirizabe kukula, ogula angathe kuyembekezera malo okhazikika komanso ogwira ntchito amphamvu omwe amayendetsedwa ndi teknoloji yatsopanoyi.
