Ka&39;idar baturi na lithium ion baturin lithium ion ya ƙunshi ingantacciyar lantarki, anode, diaphragm, da electrolyte. Ana murɗa Layer ɗin lantarki mai kyau da mara kyau tare, kuma an raba Layer da Layer daga insulator, kuma tabbatacce da korau suna nutsar da su cikin electrolyte. An yi amfani da batirin Silindrical da baturan murabba&39;i azaman baturin tsarin baturin lithium ion wanda ya ƙunshi mahaɗan lithium-insertic daban-daban, bi da bi.

Tabbataccen kayan lantarki yana da ƙarfi na ƙarfe oxide, ƙarfe oxide, ƙarfe sulfide, da makamantansu. kasuwanci Kyakkyawan kayan lantarki da aka saba amfani da su a cikin batura lithium-ion shine mafi yawan amfani da anode abu don miƙa mulki karfe oxides. The anode abu ne tam inorganic wadanda ba karfe kayan, karfe-non karfe composites, karfe oxides, da makamantansu.

lithium iron phosphate tabbatacce da korau abu An samar da kayan lantarki na lantarki akan kayan sarrafawa yana ƙayyade ƙarfin lantarki da ƙarfin ƙarfin baturin a matsayin wani yanki mai ƙarfi na baturin lithium ion, kuma yana kunna sha&39;awar watsawa na yanzu yayin cajin baturi da fitarwa. Don hana abubuwan da aka yi amfani da su a cikin electrolyte a cikin bayani na electrolytic, an raba abubuwan da ke da kyau da kuma mummunan abin da ke cikin electrolyte. Ana ɗaukar LI daga ingantacciyar wutar lantarki, kuma ana sanya wutar lantarki mara kyau a cikin gurɓataccen lantarki, ingantaccen lantarki yana cikin yanayin lithium, cajin diyya na electrons ana ba da shi ta kewayen waje don tabbatar da daidaiton caji.

Fitarwa yana da alaƙa da fitarwa, kuma ana cire Li daga gurɓataccen lantarki kuma an saka shi cikin kayan cathode ta hanyar lantarki. Karkashin yanayin caji na yau da kullun, ions lithium ana sakawa kuma ana cire su tsakanin kayan da aka yi da sinadarai na carbon da sifofi, wanda yawanci ke haifar da canje-canje a cikin tazarar kayan abu ba tare da lalata tsarin su na crystal ba. Yayin aiwatar da caji da fitarwa, tsarin sinadarai na kayan lantarki mara kyau baya canzawa.

Ma&39;aunin amsawar ion yana ƙara yuwuwa ƙara matakan tsaro a cikin baturin, saboda yana neman ƙarin ƙarfi don ƙara rayuwar baturi. Daga sayar da batirin lithium-ion na 1991 zuwa wannan hayar, ƙarfin ƙarfin batirin lithium-ion ya ƙara hanyar fashewar batirin lithium-ion sau huɗu ko biyar. Don haka mun fahimci yadda yake aiki, don haka zamu iya fahimtar abin da asalin ya haifar da fashewar baturi na lithium ion.

Caji da fitar da baturin girma na reshen lithium shine komawar ion lithium. Yayin caji, ions lithium suna raguwa zuwa ƙarfe lithium da aka saka a cikin gurɓataccen lantarki. Gabaɗaya, ana iya shigar da lithium a cikin tsarin interlayer, wanda zai iya girma a saman na&39;urar lantarki saboda rashin tabbas na girma, kuma Layer ɗin girma yana da tsari iri ɗaya da reshe, wanda zai iya lalata diaphragm na baturin, yana haifar da gajeriyar kewayawa a cikin baturin.

Da fashewar baturi. Idan baturin ya kasance m, da karfe barbashi gama tabbatacce korau electrode ta cikin baturi ta insulating Layer, canza shugabanci na halin yanzu, haifar da ciki abu zuwa ƙasƙanta, sabõda haka, da sinadaran dauki ya rasa iko, saki more zafi, ƙone baturi kunshin baturi Cajin mu na yanzu baturi yana da tsarin kariya, feedback baturi ƙarfin lantarki, tare da faɗakarwa a kan caja, wanda zai iya haifar da overcharge, bar baturi kariya tsarin ko cajin baturi faruwa a lokacin da cajin baturi ya faru. Ci gaba da cirewa da sanyawa a cikin kayan lantarki mara kyau. Idan an kai madaidaicin lithium da ke cikin carbon korau electrode, abin da ya wuce kima zai ajiye akan abu mara kyau a cikin nau&39;in ƙarfe na lithium, yana rage ƙarfin ƙarfin baturin.

Ko da fashewa yana da alaƙa da baturin lithium-ion, ba wai kawai ƙarfin baturi shine haɓakawa ba, amma aikin aminci ba za a iya watsi da shi ba. A yau, wasu masana&39;antun batir suna da babban ma&39;aunin aminci, har ma don gano batura. Mun fahimci cewa lokacin da ƙusa ya shiga cikin baturi, zai haɗa kai tsaye zuwa mummunan mummunan, wanda zai haifar da gajeren kewayawa na ciki.

Gel electrolyte da kuma polymer electrolyte suma suna ci gaba da bincike, musamman ma haɓakar polymer electrolyte, babu wani ruwa na kwayoyin halitta a cikin baturi, wanda ke inganta lafiyar baturi sosai.
