Passivation a cikin Batirin Lithium
Passivation a cikin batirin lithium, musamman waɗanda ke amfani da lithium thionyl chloride (LiSOCl2) ilmin sunadarai, yana nufin wani al'amari na kowa inda wani siririn fim ya fito a kan lithium anode. Wannan fim ɗin ya ƙunshi galibi na lithium chloride (LiCl), samfurin sinadari na farko a cikin tantanin halitta. Yayin da wannan layin wucewa na iya yin tasiri ga aikin baturi, musamman bayan dogon lokaci na rashin aiki, kuma yana taka muhimmiyar rawa wajen haɓaka rayuwar rayuwar baturi da amincinsa.
Samuwar Layer Passivation
A cikin batirin lithium thionyl chloride baturi, passivation yana faruwa ta dabi'a saboda halayen da ke tsakanin lithium anode da thionyl chloride (SOCl2) electrolyte. Wannan halayen yana samar da lithium chloride (LiCl) da sulfur dioxide (SO2) a matsayin abubuwan da aka samar. Lithium chloride a hankali yana samar da sirara, mai kauri akan saman lithium anode. Wannan Layer yana aiki azaman insulator na lantarki, yana hana kwararar ions tsakanin anode da cathode.
Amfanin Passivation
Layer passivation ba gaba ɗaya mai lahani bane. Babban fa'idarsa shine haɓaka rayuwar rayuwar baturi. Ta iyakance adadin fitar da kai na baturi, layin wucewa yana tabbatar da cewa baturin yana riƙe da cajin sa na tsawon lokaci na ajiya, yana sa batir LiSOCl2 ya dace don aikace-aikace inda dogaro na dogon lokaci ba tare da kiyayewa yana da mahimmanci ba, kamar a cikin gaggawa da ƙarfin ajiya. kayayyaki, soja, da na'urorin kiwon lafiya.
