Nzira yekugadzira ye lithium-ion mabhatiriyakaoma. Pakati pavo, kukosha kwekuita cycle performance kune lithium-ion mabhatiri zvisingatauri, uye kukanganisa kwayo pakushanda kwemabhatiri e-lithium-ion kwakakosha zvikuru. Pane iyo macro level, hupenyu hurefu hwekutenderera hunoreva kushomeka kwekushandisa. Hupenyu hwekutenderera kwebhatiri chiratidzo chakakosha chekuongorora kushanda kwebhatiri.

Rudzi rwemhando: Kusarudzwa kwezvinhu chinhu chinokanganisa kushanda kwe lithium-ion mabhatiri.

Positive and negative electrode compaction: Iyo yakanaka uye yakaipa electrode compaction yakawandisa, kunyangwe ichigona kuwedzera simba rebhatiri, asi zvakare inoderedza kutenderera kuita kwechinhu kusvika pamwero wakati.

Kunyorova: Kunyanya kunyorova kunokonzeresa maitiro epadivi neakanaka uye akaipa anoshanda zvinhu, kuparadza chimiro chayo uye kukanganisa kutenderera. Panguva imwecheteyo, mwando wakawandisa haugone kuumbwa kweSEI firimu.

Coating film density: Zvinenge zvisingaite kufunga nezve pesvedzero yefirimu density pakutenderera kwechinhu chimwe chete.

Yakawandisa yakaipa electrode: Kuwedzera kune pesvedzero yekutanga isingadzoreki simba uye density kutsauka kweiyo firimu rekupfekedza, chikonzero cheyakanyanya kunaka electrode inofungidzirwawo kukanganisa kwekuita kutenderera.

Electrolyte vhoriyamu: Pane zvikonzero zvikuru zvitatu zvekusakwana kwevhoriyamu ye electrolyte kukanganisa kutenderera. Imwe haina kukwana jekiseni vhoriyamu, uye chechipiri ndechekuti kunyangwe huwandu hwejekiseni hwakakwana, nguva yekuchembera haina kukwana kana iyo yakanaka uye yakaipa electrode haina kunyudzwa nekuda kwepamusoro compaction. Zvakakwana, chechitatu ndechekuti electrolyte mukati mebhatiri sero inopedzwa nekutenderera.

Pfupiso: Sezvakangoita dhiramu remapuranga musimboti, pakati pezvinhu zvakawanda zvinokanganisa kutenderera kuita kwe bhatiri, chinhu chekupedzisira chinogadzirisa ndicho chipfupi pakati pezvinhu zvakawanda. Panguva imwecheteyo, izvi zvinofurira zvinhu zvinewo maitiro ekudyidzana.
