Kushandiswa kwelithium-ion mabhatiriyakavandudza mararamiro evanhu zvikuru.Nekudaro, nekukurumidza kusimukira kwevanhu vemazuvano, vanhu vari kuda kumhanya kwakakwira uye kwakakwira, saka tsvakiridzo yekukurumidza kuchaja mabhatiri e-lithium-ion yakakosha.Iyi yakakwirira-simba-densitylithium-ion bhatirikukurumidza kuchaja tekinoroji ichave neyakakura tarisiro yekushandisa mune nharembozha midziyo yemagetsi, maturusi emagetsi epamusoro-soro, uye mota dzemagetsi.Nekudaro, iyo yazvino yekukurumidza kuchaja tsvagiridzo yakadziviswa nezvipingamupinyi zvakawanda, senge lithium evolution padivi regetsi remagetsi.Kuti tivandudze kukurumidza kuchaja kushanda kwemabhatiri e-lithium-ion, tinofanira kunyatsonzwisisa shanduko yemagetsi emagetsi panguva yemaitiro akanaka uye asina kunaka.
Nguva pfupi yadarika, Dr. Tanvir R. Tanim vekuUnited States vakaburitsa mapepa etsvagurudzo anechekuita.Ichi chinyorwa chinosanganisa kuongororwa kwe electrochemical, kukundikana modhi uye hunhu mushure mekuyedza kudzidza mhedzisiro yekuchaja nekukurumidza (XFC) pane cathode zvinhu pazvikero zvakawanda.Mienzaniso yekuedza inosanganisira 41 G/NMCmabhatiri ehomwe.Fast charge rate (1-9 C) uye kutenderera kusvika ku1000 times in charge state.Zvakaonekwa kuti panguva yekutanga kutenderera, dambudziko reiyo electrode yakanaka raive diki, asi pakupera kwehupenyu hwebhatiri, iyo yakanaka electrode yakaonekwa kuputika kwakajeka uye ichiperekedzwa nekuneta mashandiro, iyo yakanaka electrode kutadza kwakatanga kukurumidza.Munguva yekutenderera, chimiro chikuru cheiyo yakanaka electrode inoramba yakasimba, asi inogona kucherechedzwa kuti zvidimbu zviri pamusoro zvakagadziridzwa zvakanyanya.
Kuburikidza nekuongorora, zvinogona kuwanikwa kuti kunyangwe padanho rakaderera, kudzika kwechaji yepamusoro kuchaita kuti cathode iderere.Izvi zvinonyanya kuitika nekuti kudzika kwechaji kwepamusoro kunoita kuti kushushikana kunoitwa mukati meiyo yakanaka electrode particles kuwedzere, saka deformation yainosangana nayo yakakurawo, zvichikonzera kukuvadzwa kukuru pane imwe neimwe.
