Menene juriya na ciki na baturin lithium?
Lokacin da halin yanzu ke gudana ta cikin cikin baturi, yana fuskantar juriya, yana haifar da raguwar ƙarfin ƙarfin batirin. Wannan juriya ana kiranta juriyar ciki ta baturi. Saboda juriya na ciki na baturi, wutar lantarkin tasha yayi ƙasa da ƙarfin lantarki kuma yana buɗewa- ƙarfin lantarki yayin fitarwa. Yayin caji, wutar lantarki ta ƙarshe ya fi ƙarfin lantarki da buɗewa{4}} ƙarfin lantarki. Juriya na ciki na baturi muhimmin ma'auni ne na tushen wutar lantarki. Yana tasiri kai tsaye ƙarfin ƙarfin aiki na baturi, aiki na yanzu, ƙarfin fitarwa, da ƙarfin aiki. Don tushen wutar lantarki mai amfani, ƙananan juriya na ciki, mafi kyau.
Juriya na ciki na baturi baya dindindin; ya bambanta a lokacin fitarwa ya dogara da abun da ke cikin kayan aiki, ƙaddamarwar electrolyte, zafin baturi, da lokacin fitarwa. Juriya na ciki na baturi ya haɗa da juriya na ciki na ohmic (R₀) da juriya na ciki na polarization (Rf) wanda wayoyin lantarki ke nunawa yayin halayen lantarki. Jimlar waɗannan biyun ana kiranta jimlar ƙarfin ciki na baturi (Rw).
Juriya na ciki na Ohmic ya ƙunshi juriya na ciki na kayan lantarki, electrolyte, SEPARATOR, da juriyar hulɗar abubuwa daban-daban. Yana da alaƙa da girman baturin, tsarinsa, hanyar samar da lantarki (misali, manna{3}nau'in da tubular electrodes a cikin gubar{4}}batir ɗin acid, da akwatin{5}nau'in da sintered electrodes a cikin batura na alkaline), da matsewar taro. Juriya na ciki na Ohmic yana biyayya da dokar Ohm.
Juriya na ciki yana nufin juriya na ciki da ke haifar da polarization tsakanin ingantattun na'urorin lantarki masu inganci da mara kyau na tushen wutar sinadari yayin halayen lantarki. Jimlar juriya ce ta haifar da polarization na electrochemical da maida hankali

Juriya na ciki na polarization yana da alaƙa da yanayin kayan aiki, tsarin lantarki, da tsarin kera batir, musamman masu alaƙa da yanayin aiki na baturi; fitarwa na halin yanzu da zafin jiki suna da tasiri mai mahimmanci. A lokacin babban yawan fitarwa na yanzu, duka polarization electrochemical da maida hankali polarization suna ƙaruwa, mai yuwuwa har ma haifar da wucewar gurɓataccen lantarki, don haka ƙara juriya na ciki. Ƙananan yanayin zafi yana tasiri mummunan tasiri na polarization electrochemical da ion diffusion; saboda haka, juriya na ciki na batir ɗin yana ƙaruwa a ƙarƙashin ƙananan yanayin zafi{2}. Sabili da haka, juriya na polarization ba koyaushe ba ne, amma canje-canje tare da yawan fitarwa, zazzabi da sauran yanayi.
