Ta yaya baturin lithium-ion ke aiki? Wane fa'ida yake da shi akan baturin gubar-acid? Yaushe ajiyar baturin lithium-ion zai biya?A baturi lithium-ion(Gajeriyar: Baturin Lit-ion batir) shine kalmar da ke tattare da tarin tarin abubuwa a cikin dukkan matakai guda uku, a cikin abubuwan da aka zaɓa da wa'azin, tantanin lantarki. Baturin lithium-ion yana da takamaiman takamaiman makamashi idan aka kwatanta da sauran nau'ikan batura, amma yana buƙatar da'irar kariya ta lantarki a yawancin aikace-aikacen, yayin da suke yin mummunan tasiri ga duka zurfafawa da caji.Ana cajin batirin hasken rana na Lithium ion da wutar lantarki daga tsarin photovoltaic kuma ana sake fitar dasu kamar yadda ake buƙata. Na dogon lokaci, ana ɗaukar batir ɗin gubar a matsayin mafi kyawun maganin hasken rana don wannan dalili. Koyaya, dangane da batirin lithium-ion suna da fa'idodi masu mahimmanci, kodayake siyan yana da alaƙa da ƙarin farashi, waɗanda, duk da haka, ana samun su ta hanyar amfani da niyya.Tsarin Fasaha da Halayen Adana Makamashi na Batura Lithium-ionBatura lithium-ion ba su bambanta asali da baturan gubar-acid a tsarinsu na gaba ɗaya. Mai cajin caji ne kawai ya bambanta: Lokacin da aka yi cajin baturi, ions lithium suna "yi ƙaura" daga tabbataccen lantarki zuwa madaidaicin lantarki na baturin kuma su kasance "a adana" a wurin har sai batirin ya sake fitarwa.
