Li-ion ndi batire yocheperako, mwayi womwe ma chemistry ena ambiri sanganene.Batire ilibe kukumbukira ndipo silifunika kuchita masewera olimbitsa thupi (kutulutsa mwadala) kuti ikhale yabwino.Kudzitulutsa pawokha ndikochepera theka la makina opangira nickel ndipo izi zimathandiza kugwiritsa ntchito gauge yamafuta.Mphamvu yamagetsi yamagetsi ya 3.60V imatha kupatsa mphamvu mafoni am'manja, mapiritsi ndi makamera a digito, kupangitsa kuti zikhale zosavuta komanso zochepetsera mtengo pamapangidwe amafoni ambiri.Zolepheretsa ndizofunika kwa mabwalo achitetezo kuti apewe kuzunzidwa, komanso mtengo wokwera.
Mitundu ya Mabatire a Lithium-ion

Li-ion ndi batire yocheperako, mwayi womwe ma chemistry ena ambiri sanganene.Batire ilibe kukumbukira ndipo silifunika kuchita masewera olimbitsa thupi (kutulutsa mwadala) kuti ikhale yabwino.Kudzitulutsa pawokha ndikochepera theka la makina opangira nickel ndipo izi zimathandiza kugwiritsa ntchito gauge yamafuta.Mphamvu yamagetsi yamagetsi ya 3.60V imatha kupatsa mphamvu mafoni am'manja, mapiritsi ndi makamera a digito, kupangitsa kuti zikhale zosavuta komanso zochepetsera mtengo pamapangidwe amafoni ambiri.Zolepheretsa ndizofunika kwa mabwalo achitetezo kuti apewe kuzunzidwa, komanso mtengo wokwera.
Batire yoyambirira ya Sony lithiamu-ion idagwiritsa ntchito coke ngati anode (mankhwala a malasha).Kuyambira 1997, ambiri opanga ma ion a Li ion, kuphatikiza Sony, adasinthiratu ku graphite kuti apeze njira yotulutsa bwino.Graphite ndi mtundu wa kaboni womwe umakhala wokhazikika kwa nthawi yayitali ndipo umagwiritsidwa ntchito m'mapensulo amtovu.Ndiwofala kwambiri wa carbon, wotsatiridwa ndi ma carbon olimba ndi ofewa.Ma carbon a Nanotube sanapezebe kugwiritsidwa ntchito kwa malonda ku Li-ion chifukwa amakonda kulowerera komanso kukhudza magwiridwe antchito.Zamtsogolo zomwe zimalonjeza kupititsa patsogolo ntchito ya Li-ion ndi graphene.
Chithunzi 2 chikuwonetsa mayendedwe amagetsi a Li-ion amakono okhala ndi graphite anode ndi mtundu woyambirira wa coke.
Zowonjezera zingapo zayesedwa, kuphatikiza ma aloyi opangidwa ndi silicon, kuti apititse patsogolo magwiridwe antchito a graphite anode.Zimatengera maatomu asanu ndi limodzi a carbon (graphite) kuti amangirire ku ion imodzi ya lithiamu;atomu imodzi ya silicon imatha kumangirira ma ion anayi a lithiamu.Izi zikutanthauza kuti anode ya silicon imatha kusunga mphamvu yopitilira 10 mphamvu ya graphite, koma kukulitsa anode panthawi yolipira ndizovuta.Silicone anode yoyera sizothandiza ndipo 3-5 peresenti yokha ya silicon ndiyomwe imawonjezedwa ku anode ya silicon-based kuti mupeze moyo wabwino wozungulira.
Kugwiritsa ntchito nano-structured lithiamu-titanate monga chowonjezera cha anode chimasonyeza moyo wozungulira, mphamvu zabwino zolemetsa, ntchito yabwino kwambiri yotsika kutentha komanso chitetezo chapamwamba, koma mphamvu zenizeni ndizochepa ndipo mtengo wake ndi wapamwamba.
Kuyesera ndi zinthu za cathode ndi anode kumalola opanga kulimbitsa mikhalidwe yamkati, koma chowonjezera chimodzi chikhoza kusokoneza china.Zomwe zimatchedwa "Energy Cell" zimakonza mphamvu zenizeni (mphamvu) kuti zikwaniritse nthawi yayitali koma mphamvu zochepa;"Power Cell" imapereka mphamvu zapadera koma zocheperako."Hybrid Cell" ndiyonyengerera ndipo imapereka pang'ono zonse ziwiri.
Opanga amatha kupeza mphamvu zenizeni komanso zotsika mtengo mosavuta powonjezera faifi tambala m'malo mwa cobalt yokwera mtengo, koma izi zimapangitsa kuti selo likhale lokhazikika.Ngakhale kampani yoyambira ikhoza kuyang'ana kwambiri mphamvu zenizeni komanso mtengo wotsika kuti uvomerezedwe mwachangu pamsika, chitetezo ndi kulimba sizingasokonezedwe.Opanga odziwika amaika kukhulupirika kwakukulu pachitetezo ndi moyo wautali.
Mabatire ambiri a Li-ion ali ndi mapangidwe ofanana omwe ali ndi chitsulo cha oxide positive electrode (cathode) chomwe chimakutidwa ndi chotengera chamakono cha aluminiyamu, electrode negative (anode) yopangidwa kuchokera ku kaboni / graphite wokutidwa pa chotolera chamkuwa, cholekanitsa ndi electrolyte. zopangidwa ndi mchere wa lithiamu mu zosungunulira za organic.Zambiri, pls pitani ndi teda battery.com.
Table 3 ikufotokoza mwachidule ubwino ndi malire a Li-ion.
