Abubuwan da ke cikin Lithium Electrolytes na gama gari
Abubuwan kaushi na halitta sune manyan abubuwan da ke cikin electrolyte, suna lissafin kusan 80% ~ 90%. Wadannan kaushi sun hada da ethylene carbonate (EC), dimethyl carbonate (DMC), propylene carbonate (PC), diethyl carbonate (DEC), ethyl methyl carbonate (EMC), da dai sauransu.
Gishirin lithium wani sinadari ne na electrolyte kuma shine asalin tushen lithium. Waɗannan gishirin lithium sun haɗa da lithium hexafluorophosphate (LiPF6), lithium bis (fluorosulfonyl) imide (LiFSI), lithium tetrafluoroborate (LiBF₄), lithium perchlorate (LiClO₄), da dai sauransu.
Additives lissafin kusan 5% na electrolyte. Waɗannan abubuwan ƙarawa sun haɗa da fim -ƙaddamar ƙararrawa, harshen wuta{3}}abin da ake ƙarawa, masu daidaitawa, da sauransu. Misali, fim ɗin gama-gari{5}}ƙara irin su vinyl carbonate (VC), fluorinated vinyl carbonate (FEC).
Gabaɗaya, aikin lithium electrolyte ya dogara ne akan tasirin synergistic na kaushi, gishiri lithium da ƙari. Misali, hadewar EC/DMC hade da sauran ƙarfi da LiPF6iya daidaita duka ionic conductivity da kwanciyar hankali.
Tasirin Kasancewar Ruwa A Cikin Electrolytes
Wadancan abubuwan suna da matukar kula da aikin sinadarai na lantarki, ruwa da datti na iya yin tasiri sosai ga samarwa da ingancin batirin lithium. Misali:
Ruwa na iya mayar da martani ta hanyar sinadarai tare da gishirin lithium a cikin electrolyte don samar da abubuwa masu cutarwa irin su hydrofluoric acid (HF) da lithium fluoride (LiF), wanda zai iya lalata tsarin baturi, haifar da ɗigo ko gajeriyar kewayawa, da rage ƙarfin baturi.
Fim ɗin da aka samar da shi da fim ɗin - abubuwan da ke haifarwa na iya lalacewa ta hanyar ruwa, yana rasa yawansa da daidaito, wanda ke haifar da haɓaka juriya na ciki na baturi da raguwar ƙarfin fitarwa.

Sieves Na Halitta Don Rashin Ruwan Ruwa
Aikace-aikacen sieves na kwayoyin halitta a cikin electrolytes sun bambanta dangane da takamaiman dalilansu, kamar bushewar ƙarfi, bushewar electrolyte da deacidification, sabuntawar electrolyte, da haɓaka aikin lantarki.
Nau'in 5A Zeolite Molecular Sieve shine mafi fifiko ga rashin ruwa na electrolyte, kuma yana iya cire ruwa yadda yakamata daga electrolyte, yana hana haɓaka juriya na ciki da halayen lantarki, ta haka inganta aiki da amincin batirin lithium.
