Njira yopanga batire ya lithiamu: njira yomaliza

M'mbuyomu, tidayambitsa njira yakutsogolo ndi yapakati yakupanga batire ya lithiamu mwatsatanetsatane. Nkhaniyi idzapitiriza kufotokoza ndondomeko ya kumbuyo.

Cholinga chopanga cham'mbuyo ndikumaliza kupanga ndi kuyika batire ya lithiamu-ion. M'kati mwa siteji yapakati, mawonekedwe ogwirira ntchito a selo apangidwa, ndipo maselowa amayenera kutsegulidwa pambuyo pake. Njira yayikulu m'magawo am'tsogolo ndi monga: mu chipolopolo, kuphika vacuum (kupukuta vacuum), jekeseni wa electrolyte, kukalamba, ndi mapangidwe.

Indi chipolopolo

Amatanthawuza kulongedza cell yomalizidwa mu chipolopolo cha aluminiyamu kuti athandizire kuwonjezera ma electrolyte ndikuteteza mawonekedwe a cell.

Kuphika utupu (vacuum kuyanika)

Monga amadziwika kwa onse, madzi amapha mabatire a lithiamu. Izi zili choncho chifukwa madzi akakumana ndi electrolyte, asidi wa hydrofluoric amapangidwa, zomwe zingawononge kwambiri batire, ndipo mpweya wotuluka umapangitsa kuti batire iwonongeke. Choncho, madzi mkati mwa lithiamu-ion batire selo ayenera kuchotsedwa msonkhano msonkhano pamaso jekeseni electrolyte kupewa kukhudza khalidwe la lithiamu-ion batire.

Kuphika kwa vacuum kumaphatikizapo kudzaza nayitrogeni, vacuum, ndi kutentha kwambiri. Kudzaza kwa nayitrojeni ndikulowetsa mpweya ndikuphwanya chofufumitsa (kuthamanga kwanthawi yayitali kungawononge zida ndi batri. Kudzaza kwa nayitrojeni kumapangitsa kuti mpweya wamkati ndi wakunja ukhale wofanana) kuti upangitse kutenthetsa kwamafuta ndikulola kuti madzi asungunuke bwino. Pambuyo pa njirayi, chinyontho cha batri ya lithiamu-ion chimayesedwa, ndipo ndondomeko yotsatira ikhoza kupitilizidwa pambuyo poti maselowa apambana mayeso.

Jakisoni wa electrolyte

Jekeseni amatanthauza njira yobaya electrolyte mu batri molingana ndi kuchuluka kofunikira kudzera mu dzenje losungika la jakisoni. Amagawidwa kukhala jekeseni woyambirira ndi jekeseni yachiwiri.

Kukalamba

Kukalamba amatanthauza kuyika pambuyo mlandu woyamba ndi mapangidwe, amene akhoza kugawidwa mu yachibadwa kutentha ukalamba ndi kutentha ukalamba. Njirayi imapangidwira kuti katundu ndi mapangidwe a filimu ya SEI apangidwe pambuyo pa malipiro oyambirira ndi mapangidwe okhazikika, kuonetsetsa kukhazikika kwa electrochemical batire.

Formation

Batire imatsegulidwa kudzera mu charger yoyamba. Panthawiyi, filimu yogwira ntchito (SEI filimu) imapangidwa pamwamba pa electrode yoipa kuti ikwaniritse "kuyambitsa" kwa batire ya lithiamu.

Kusankha

Grading, ndiko kuti, "kuwunika mphamvu", ndikulipiritsa ndikutulutsa ma cell pambuyo pakupanga molingana ndi mapangidwe apangidwe kuti ayese mphamvu yamagetsi yama cell kenako amasiyidwa molingana ndi mphamvu zawo.

Panjira yonse yakumbuyo, kuphika vacuum ndikofunikira kwambiri. Madzi ndi "mdani wachilengedwe" wa batri ya lithiamu-ion ndipo amagwirizana mwachindunji ndi khalidwe lawo. Kupanga ukadaulo wowumitsa vacuum kwathetsa bwino vutoli.

Dacheng mwatsatanetsatane vacuum kuyanika mankhwala mndandanda

Mzere wowumitsa wa vacuum wa Dacheng mwatsatanetsatane uli ndi zinthu zitatu zazikuluzikulu: uvuni wa vacuum wophikira mumsewu, uvuni wa vacuum wophikira monomer, ndi uvuni wokalamba. Iwo akhala akugwiritsidwa ntchito ndi pamwamba lithiamu batire opanga makampani, kulandira matamando mkulu ndi ndemanga zabwino.

Dacheng Precision ili ndi gulu la akatswiri a R&D omwe ali ndi luso lapamwamba, luso lazopangapanga komanso luso lolemera. Pankhani ya ukadaulo wowumitsa vacuum, Dacheng Precision yapanga ukadaulo woyambira wophatikizira ukadaulo wophatikizira mitundu yambiri, makina owongolera kutentha, komanso magalimoto ozungulira otumizira ovuni yowotchera vacuum, ndi zabwino zake zopikisana.
