Mabatire a lithiamu-ion ali ndi ubwino wokhala ndi mphamvu zazikulu, moyo wautali wautali, komanso osakumbukira. Akhala batire yokondeka pazinthu zamagetsi zamagetsi padziko lonse lapansi komanso batire yayikulu yamagetsi atsopano. Kuonjezera ma conductive agents kuzinthu zabwino zama elekitirodi ndi njira yabwino yopititsira patsogolo magwiridwe antchito a mabatire a lithiamu.
Itha kukulitsa kwambiri ma elekitirodi abwino komanso oyipa, kuwonjezera kuchuluka kwa mphamvu ya batri, ndikuchepetsa kukana. , kuonjezera kuthamanga kwa deintercalation ndi kuyika kwa lithiamu ion, kumapangitsanso kwambiri kuchuluka kwa batire ndi kutulutsa ntchito, komanso kupititsa patsogolo kuyendetsa mofulumira kwa magalimoto amagetsi. zinthu mu electrode batire.

Mwachidziwitso, ma elekitirodi a graphene amatha kukhala ndi kuwirikiza kawiri mphamvu yeniyeni ya graphite. Komanso, ngati graphene ndi mpweya wakuda zimasakanizidwa ndikuwonjezedwa ngati zowonjezera zowonjezera ku mabatire a lithiamu, kukana kwamkati kwa batire kumatha kuchepetsedwa bwino, ndipo kuchuluka kwa batire ndi kuchuluka kwa batire. magwiridwe antchito komanso moyo wozungulira ukhoza kuwongolera.
Kuphatikiza apo, kupindika kwa batire sikumakhudzanso kuwongolera ndi kutulutsa, chifukwa chake ma elekitirodi amapangidwa ndi graphite. Pambuyo pa zida za graphene, batire imakhala ndi mtengo wokwera komanso kutulutsa, chifukwa chake mabatire a graphene amathamangitsa mwachangu.
