Tsarinbatirin lithium

Abubuwan da ke cikin batirin lithium galibi sun haɗa da kayan lantarki masu kyau, kayan lantarki masu kyau, masu rabawa, electrolytes, da casings.

1. Daga cikin kayan lantarki masu kyau, kayan da aka fi amfani da su sune lithium cobaltate, lithium manganate, lithium iron phosphate da kayan ternary (polymers na nickel, cobalt da manganese). Kayan lantarki masu kyau suna da babban rabo (rabo na kayan lantarki masu kyau da marasa kyau shine 3:1~4:1), saboda aikin kayan lantarki masu kyau yana shafar aikin batirin lithium-ion kai tsaye, kuma farashinsa kuma yana ƙayyade farashin batirin kai tsaye.
2. Daga cikin kayan lantarki masu cutarwa, graphite na halitta da graphite na wucin gadi a halin yanzu sune manyan kayan lantarki masu cutarwa. Kayan da ake binciken su sun haɗa da nitrides, polyaspartic acid, oxides na tin-based, tin alloys, nano-anode kayan, da sauran mahaɗan ƙarfe. A matsayin ɗaya daga cikin manyan kayan batirin lithium guda huɗu, kayan lantarki masu cutarwa suna taka muhimmiyar rawa wajen inganta ƙarfin baturi da aikin zagayowar, kuma suna kan gaba a tsakiyar masana'antar batirin lithium.
3. Kayan diaphragm da ake amfani da su a kasuwa galibi su ne diaphragms na polyolefin, waɗanda galibi an yi su ne da polyethylene da polypropylene. A cikin tsarin mai raba batirin lithium, mai raba yana ɗaya daga cikin mahimman abubuwan ciki. Aikin mai raba yana ƙayyade tsarin haɗin gwiwa da juriyar ciki na batirin, wanda ke shafar ƙarfin baturi, zagayowar da aikin aminci kai tsaye. Mai raba baturi mai kyakkyawan aiki yana taka muhimmiyar rawa wajen inganta aikin batirin gabaɗaya.
4. Ana yin electrolyte ɗin ne da sinadarai masu ƙarfi na halitta, gishirin lithium na electrolyte, ƙarin abubuwa masu mahimmanci da sauran kayan aiki a wani yanki a ƙarƙashin wasu yanayi. Elektrelu yana taka rawar da ke tafiyar da ions tsakanin electrodes masu kyau da marasa kyau na batirin lithium, wanda shine garantin babban ƙarfin lantarki da kuma babban kuzari na batirin lithium ion.
5. Akwatin batirin: an raba shi zuwa kwandon ƙarfe, kwandon aluminum, kwandon ƙarfe mai ɗauke da nickel (don batirin silinda), fim ɗin filastik na aluminum (marufi mai laushi), da sauransu, da kuma murfin baturin, wanda kuma shine tashoshi masu kyau da marasa kyau na batirin.
6. Ka'idar aikin Baturi
7. Idan aka yi caji da batirin, ana samar da ions na lithium akan na'urar lantarki mai kyau ta batirin, kuma ions na lithium da aka samar suna motsawa zuwa na'urar lantarki mai kyau ta hanyar electrolyte. Tsarin carbon na na'urar lantarki mai kyau yana da ramuka da yawa, kuma ions na lithium da suka isa ga na'urar lantarki mai kyau suna cikin ƙananan ramuka na layin carbon. Da yawan ions na lithium da aka saka, haka nan ƙarfin caji zai yi girma. Lokacin da aka fitar da batirin, ions na lithium da aka saka a cikin layin carbon na na'urar lantarki mai kyau suna fitowa kuma suna komawa zuwa na'urar lantarki mai kyau. Da yawan ions na lithium da suka koma na'urar lantarki mai kyau, haka nan ƙarfin fitarwa ya fi girma. Gabaɗaya, ƙarfin fitarwa yana nufin ƙarfin fitarwa. A lokacin caji da fitarwa na batirin lithium, ions na lithium suna cikin yanayin motsi daga na'urar lantarki mai kyau zuwa na'urar lantarki mai kyau. Idan an kwatanta hoton batirin lithium da kujera mai girgiza, ƙarshen kujera mai girgiza su ne na'urorin lantarki masu kyau da marasa kyau na baturi, kuma ions na lithium kamar 'yan wasa ne, suna gudu da gaba tsakanin ƙarshen kujera mai girgiza. Don haka ana kiran batirin lithium batirin kujera mai girgiza.
