Haɗin baturin lithium-ion

Haɗawa da sake yin amfani da baturin lithium-ion

Thebaturi lithium-ionAn hada da eletrolyte, SEPARATOR, cathode da anode da harka.

A electrolytea cikin baturin lithium-ion zai iya zama gel ko polymer, ko cakuda gel da polymer.

Electrolyte a cikin batirin Li-ion yana aiki azaman matsakaici don jigilar ions a cikin baturi.Yawanci ya ƙunshi gishirin lithium da kaushi na halitta.Electrolyte yana taka muhimmiyar rawa wajen jigilar ion tsakanin ingantattun na'urorin lantarki na baturin lithium-ion, tabbatar da cewa baturin zai iya samun babban ƙarfin lantarki da ƙarfin kuzari.Electrolyte gabaɗaya ya ƙunshi manyan kaushi mai tsafta, gishirin lithium electrolyte da abubuwan da ake buƙata a haɗe a hankali cikin ƙayyadaddun rabbai ƙarƙashin takamaiman yanayi.

Kayan cathodenau'ikan batirin lithium-ion:

• LiCoO2
• Farashin 2MnO3
• LiFePO4
• NCM
• NCA

 Kayan cathode sun ƙunshi sama da 30% na farashin batirin gabaɗaya.

A anodebaturin lithium-ion ya ƙunshi

Sannan anode na batirin lithium-ion ya ƙunshi kusan kashi 5-10 na ƙimar batirin gabaɗaya.Abubuwan anode na tushen Carbon abu ne na anode da aka saba amfani da shi don batir lithium-ion.Idan aka kwatanta da na gargajiya karfe lithium anode, yana da mafi girma aminci da kwanciyar hankali.Abubuwan anode na tushen carbon sun fito ne daga graphite na halitta da na wucin gadi, fiber carbon da sauran kayan.Daga cikin su, graphite shine babban abu, wanda ke da ƙayyadaddun yanki na musamman da wutar lantarki, kuma kayan carbon kuma suna da kwanciyar hankali mai kyau da sake amfani da su.Koyaya, ƙarfin kayan lantarki mara kyau na tushen carbon yana da ƙarancin ƙarancin ƙarfi, wanda ba zai iya biyan buƙatun wasu aikace-aikacen don babban ƙarfin aiki ba.Sabili da haka, a halin yanzu akwai wasu bincike akan sababbin kayan carbon da kayan haɗin gwiwa, da fatan ƙara haɓaka iya aiki da rayuwar sake zagayowar kayan lantarki mara kyau na tushen carbon.

Har yanzu yana da silica-carbon negtive electrode abu.Silicon (Si) abu: Idan aka kwatanta da na gargajiya carbon korau electrodes, silicon korau electrodes suna da mafi girma takamaiman iya aiki da makamashi yawa.Duk da haka, saboda girman girman girman kayan siliki, yana da sauƙi don haifar da haɓakar ƙarar wutar lantarki, ta haka yana rage rayuwar baturi.

Mai rabana baturin lithium-ion wani muhimmin bangare ne na tabbatar da aikin baturi da aminci.Babban aikin mai raba shi ne don raba ingantattun na'urori masu kyau da marasa kyau, kuma a lokaci guda, yana iya samar da tashar don motsin ion da kuma kula da mahimmancin electrolyte.An gabatar da ayyuka da sigogi masu alaƙa na mai raba baturin lithium-ion kamar haka:

1. Chemical kwanciyar hankali: Diaphragm ya kamata ya sami kyakkyawan kwanciyar hankali na sinadarai, juriya mai kyau da juriya na tsufa a ƙarƙashin yanayi mai ƙarfi na kwayoyin halitta, kuma yana iya kula da aikin barga a ƙarƙashin yanayi mai tsanani kamar yanayin zafi da zafi mai zafi.

2. Ƙarfin injina: Mai rarraba ya kamata ya sami isasshen ƙarfin injina da kuma elasticity don tabbatar da isasshen ƙarfi da juriya don hana lalacewa yayin haɗuwa ko amfani.

3. Ionic conductivity: A karkashin tsarin kwayoyin halitta, ion conductivity yana da ƙasa da na tsarin lantarki mai ruwa, don haka mai rarraba ya kamata ya kasance yana da halaye na ƙananan juriya da haɓakar ionic.A lokaci guda kuma, don rage juriya, kauri na mai raba ya kamata ya zama bakin ciki kamar yadda zai yiwu don sanya yankin lantarki ya zama babba kamar yadda zai yiwu.

4. Zaman lafiyar zafi: Lokacin da rashin daidaituwa ko gazawa irin su cajin da aka yi da yawa, zubar da ruwa, da gajeren kewayawa sun faru yayin aikin baturi, mai rarraba dole ne ya sami kwanciyar hankali mai kyau.A wani yanayi na zafi, diaphragm ya kamata ya yi laushi ko narke, ta haka zai toshe kewayen baturi da kuma hana haɗarin amincin baturi.

5. Isasshen wetting da tsarin pore mai sarrafawa: Tsarin pore da shafi na mai raba ya kamata ya sami isasshen ikon sarrafa jika don tabbatar da mai rarrabawa, don haka inganta wutar lantarki da rayuwar baturi.Gabaɗaya magana, polyethylene flake (PP) da polyethylene flake (PE) microporous diaphragms kayan aikin diaphragm ne gama gari a halin yanzu, kuma farashin yana da arha.Amma akwai wasu kayan raba batirin lithium-ion, irin su polyester, waɗanda ke da kyakkyawan aiki, amma farashin yana da inganci.
