Kupambana kwakukulu: 500Wh / kg lithiamu chitsulo batri, idakhazikitsidwa mwalamulo!

Lero m'mawa, kuwulutsa kwa CCTV "Chao Wen Tianxia",batire ya lithiamu zitsulo yopikisana padziko lonse lapansimzere wopanga zidatsegulidwa mwalamulo ku Hefei.Mzere wopanga womwe unayambika nthawi ino wapeza kupambana kwakukulu mukachulukidwe kamphamvu ka m'badwo watsopano wa mabatire a lithiamu zitsulo500Wh/kg.Zikumveka kuti iyi ndi mzere woyamba wodzipatulira wopanga makina opangira batire a lithiamu zitsulo ku China komanso padziko lonse lapansi.

Pulofesa Zhang Yuegang wa ku yunivesite ya Tsinghua adanena pazochitikazo kuti ndi kusintha kwa mphamvu padziko lonse ndi kupititsa patsogolo, vuto la "kupirira nkhawa" likupitiriza kukankhira malire a zamakono zamakono, zomwe zimafuna kuti mphamvu ya batri ipitirire kukwera.Mabatire achitsulo a lithiamu amagwiritsa ntchito zitsulo zoyera za lithiamumonga electrode negative, ndi ultra-high theoretical mphamvu yeniyeni ndi mphamvu zochepa kwambiri, zomwe zimapangitsa mabatire a lithiamu zitsulo akuyembekezekakupitilira kuwirikiza kawiri kuchuluka kwa magalimoto amagetsi. Ndi ukadaulo wotsogola wotsogola pamsika wamakono wa batri. mayendedwe ofunikira achitukuko.

Kutsegula kwathunthu kwa mzere wopanga batire ya lithiamu zitsulo ku Hefei kukuwonetsa kuti ChinaKuthekera kwa batch ya 500 Wh/kg yamphamvu yamagetsi yamphamvu kwambiri yatsogola kwambiri padziko lonse lapansi, ndikuzindikira kukula kwa mabatire a lithiamu zitsulo kuchokera ku labotale (TRL3) mpaka Kupambana mu gawo loperekera batch ( TRL6-8).M'tsogolomu, zogulitsazo zikuyembekezeka kukhala ndi gawo lalikulu pakuyendetsa ndege zamagetsi, magalimoto amagetsi atsopano ndi mafakitale ena.Mzere wodzipatulirawu wopangidwa ku Hefei udzalimbikitsanso kukweza kwa mafakitale ndi chitukuko chapamwamba, kubweretsa mwayi wambiri wotsegulira zochitika zapansi pa mtsinje wa mabatire atsopano a mphamvu.

Malinga ndi chidziwitso chamagetsi, mzere wapadera wopangira 500Wh/kg zodziwikiratu za lithiamu zitsulo zopanga batire zimazindikirika ndi Anhui Mengwei New Energy Technology Co., Ltd. yomwe ili ku Feiqidi Science and Technology City, Economic Development Zone, Hefei City.Mu June chaka chatha, Anhui Mengwei New Energy Technology Co., Ltd. akwaniritsa yojambula yaikulu mu kachulukidwe mphamvu m'badwo watsopano wa mabatire zitsulo lithiamu 500Wh/kg.Mzere wodzipatulira wamakono wopanga batire ya lithiamu zitsulo ukuwonetsa kuti batire ya chitsulo ya 500Wh/kg ya kampaniyo yakhala yovomerezeka.adalowa mugawo la kupanga malonda ambiri.

Malinga ndi luso lamagetsi,mu Novembala 2021, Anhui Mengwei New Energy Technology Co., Ltd. ndi Hefei Economic and Technological Development Zone anasaina mgwirizano ndalama kwa dongosolo latsopano mphamvu batire R&D ndi kupanga m'munsi polojekiti, ndi Mengweixin dongosolo mphamvu batire R&D ndi kupanga m'munsi polojekiti mwalamulo anakhazikika mu Hefei.Monga wofufuza mabatire a lithiamu zitsulo, kukhazikitsidwa kwa mphamvubatireR&D ndi kupanga m'munsi polojekiti ya Mengweixin dongosolo chizindikiro kuti lifiyamu kutsogolera dzikomabatire achitsulo adzatsogolera pakuzindikira kupanga kwakukulu ku Hefei.

Gulu pachimake Mengwei New Energy wapangidwa luso sayansi ndi luso ndi osankhika makampani ku mayunivesite odziwika bwino ndi mabizinesi benchmarking kunyumba ndi kunja monga Tsinghua University, University of Science and Technology of China, Chinese Academy of Sciences, etc.gulu luso lifiyamu zitsulo batire luso luso ndi waukulu kupanga mankhwala, ndipo ali angapo mayiko mpikisano kutsogolera luso m'madera okhudzana monga lifiyamu batire cathode ndi anode kapangidwe zinthu, electrolyte kukhathamiritsa, diaphragm kusinthidwa, kupanga selo ndi wanzeru. kupanga zokha. .

Kodi lingaliro la 500 Wh / kg ndi chiyani?Malinga ndi malipoti, kutenga Tesla ya 2019Mtundu wautali wa S/X wokhala ndi maulendo ataliatali kwambiri omwe akugulitsidwa mwachitsanzo, kuchuluka kwa mphamvu zama cell a batri omwe amagwiritsidwa ntchito ndi pafupifupi 243 Wh/kg.Kuchulukana kwamphamvu kwa batire kuli pafupi ndi 500 Wh/kg, komwe kuli kofunika kwambiri, ndiko kuti, kumatha kuwirikiza kawiri kuchuluka kwa magalimoto amagetsi apano..

Mabatire achitsulo a lithiamu ndi mitundu yatsopano ya mabatire okhala ndi zitsulo za lithiamu monga electrode yoyipa. Makampani ambiri amazindikira kuti olimba-boma mabatire adzakhala m'badwo wotsatira teknoloji batire, ndi olimba boma electrolytes akhoza kwenikweni kutenga mwayi wawo mkulu kachulukidwe mphamvu pamene pamodzi ndi lithiamu zitsulo zoipa maelekitirodi.Anhui Mengwei Chatsopano Energy wayala malonda a mabatire zitsulo lifiyamu pasadakhale, mwachangu anatsegula "makilomita otsiriza" za labotale ndi ntchito malonda, ndipo akufuna kuyamba malonda a luso olimba boma batire kupereka zambiri apamwamba ndi opepuka. mphamvu zopangira magetsi ndege ndi magalimoto.Kumbali ya chitetezo, chimene anthunkhawa kwambiri, Mengwei New Energy a lithiamu zitsulo batire alinso ndi ntchito yabwino.Kaya ndi zovuta malire a kutentha otsika ndi kutentha kwambiri, kapena mayesero chitetezo monga zitsulo singano puncture, Mengwei New Energy a lithiamu zitsulo batire luso lafika pa mlingo mayiko kutsogolera.
