Mabatire a lithiamu-ion amathandizira miyoyo ya anthu mamiliyoni ambiri tsiku lililonse.Kuchokera pamalaputopu ndi mafoni a m'manja mpaka ma hybrids ndi magalimoto amagetsi, ukadaulo uwu ukukula kutchuka chifukwa cha kulemera kwake, kuchulukira kwamphamvu, komanso kuthekera kowonjezera.
Ndiye zimagwira ntchito bwanji?
Makanema awa amakuyendetsani.
ZOCHITIKA
Batire imapangidwa ndi anode, cathode, separator, electrolyte, ndi otolera awiri apano (zabwino ndi zoyipa).Anode ndi cathode amasunga lithiamu.Electrolyte imanyamula ayoni a lithiamu kuchokera ku anode kupita ku cathode ndi mosemphanitsa kudzera pa olekanitsa.Kuyenda kwa ayoni a lithiamu kumapanga ma elekitironi aulere mu anode yomwe imapangitsa kuti pakhale mtengo wokhometsa wapano.Mphamvu yamagetsi imayenda kuchokera ku chosonkhanitsa chamakono kudzera pa chipangizo chomwe chimayendetsedwa (foni yam'manja, kompyuta, ndi zina zotero) kupita ku chosonkhanitsa chamakono.Cholekanitsa chimatchinga kuyenda kwa ma elekitironi mkati mwa batire.
KULIMBITSA/KUTHA
Pamene batire ikutulutsa ndikupereka mphamvu yamagetsi, anode imatulutsa lithiamu ion ku cathode, ndikupanga kutuluka kwa ma electron kuchokera mbali imodzi kupita ku imzake.Mukalumikiza chipangizocho, zosiyana zimachitika: Lithiamu ion amatulutsidwa ndi cathode ndikulandiridwa ndi anode.
ENERGY DENSITY VS.KUCHULUKA KWA MPHAMVU Mfundo ziwiri zodziwika bwino zomwe zimagwirizanitsidwa ndi mabatire ndi kuchuluka kwa mphamvu ndi kuchuluka kwa mphamvu.Kuchuluka kwa mphamvu kumayesedwa mu maola a watt pa kilogalamu (Wh/kg) ndipo ndi kuchuluka kwa mphamvu zomwe batire lingasunge potengera kulemera kwake.Kuchuluka kwa mphamvu kumayesedwa mu watts pa kilogalamu (W/kg) ndipo ndi kuchuluka kwa mphamvu zomwe zingapangidwe ndi batire potengera kulemera kwake.Kuti mujambula bwino, ganizirani za kukhetsa dziwe.Kuchuluka kwa mphamvu kumafanana ndi kukula kwa dziwe, pamene mphamvu yamagetsi ikufanana ndi kukhetsa dziwe mwamsanga.Ofesi ya Vehicle Technologies Office imagwira ntchito yokulitsa kuchuluka kwa mphamvu zamabatire, ndikuchepetsa mtengo wake, ndikusunga mphamvu zovomerezeka.Kuti mudziwe zambiri za batri, pls pitani:
