Latium polymer batri

lifiyamu polima batire

Mabatire a lithiamu-ion ndi lithiamu polima ndi mitundu ya batri yobwereketsa yomwe ili ndi lithiamu ngati chinthu chogwiritsa ntchito electrochemical. Mabatire a Li-ion ndi amodzi mwama cell omwe amadziwika kwambiri padziko lonse lapansi pazamagetsi zam'manja. M'zaka zaposachedwa, kupanga kwakukulu kwa ma cellwa kwalimbikitsidwa ndi kufunikira kwa magalimoto amagetsi ophatikizika ndi ma gridi osungira.

Mabatire a lithiamu-ion anali mabatire oyamba ochita bwino kubweza amitundu yonse, kuwapangitsa kudziwika bwino. Amayang'anira msika wamagetsi osunthika chifukwa cha kuchuluka kwa mphamvu zawo, kuthamangitsa mwachangu komanso kusowa kwa kukumbukira. Kutulutsa kwamphamvu kwamakono kwa zida zamphamvu za lithiamu-ion kumapangitsa kuti zikhale zabwino kwambiri pazogwiritsa ntchito monga matabwa, kubowola ndi kugaya.

Mabatire a lithiamu polima ndi opyapyala, mabatire athyathyathya okhala ndi anode yolumikizana ndi zida za cathode zolekanitsidwa ndi polima electrolyte. Ma electrolyte a polima amatha kuwonjezera kusinthasintha kwa batri, kupangitsa kuti ikhale yosavuta kunyamula m'malo ang'onoang'ono kuposa mabatire a lithiamu-ion.

Ambiri mawonekedwe a lithiamu polima batire ntchito lithiamu ion anode ndi organic electrolyte, ndi elekitirodi zoipa zopangidwa carbon ndi anode gulu cathode zakuthupi. Izi zimadziwika kuti lithiamu polymer primary cell.

Batire ya lithiamu-ion yochokera ku lithiamu-ion imagwiritsa ntchito anode yachitsulo ya lithiamu, cathode yakuda ya kaboni ndi organic electrolyte. Electrolyte ndi yankho la zosungunulira organic, mchere wa lithiamu ndi polyvinylidene fluoride. Anode ikhoza kupangidwa kuchokera ku carbon kapena graphite, cathode imapangidwa kuchokera ku manganese dioxide.

Mitundu yonse iwiri ya mabatire imagwira ntchito bwino pakutentha kotsika koma mabatire a lithiamu polima amakhala ndi magetsi ochulukirapo kuposa cell ya lithiamu-ion cell. Izi zimalola kuti pakhale ma batire ang'onoang'ono olongedza komanso opepuka kulemera kwazinthu zamagetsi zomwe zimagwiritsidwa ntchito ndi 3.3 volts kapena kuchepera, monga ma eReader ambiri ndi mafoni am'manja.

Mphamvu yamagetsi ya maselo a lithiamu-ion ndi 3.6 volts, pamene mabatire a lithiamu polima akupezeka kuchokera ku 1.5 V mpaka 20 V. Kulumikizana kwakukulu mu anode.
