Batir mai cajin motar lantarki da kai da sauri wanda cibiyar wutar lantarki ta jami’ar jihar Pennsylvania da kuma dakin gwaje-gwajen injiniya na kasa na motocin lantarki na jami’ar fasaha ta Beijing suka samar da sabon ci gaba. An buga sakamakonsa a cikin mujallar ilimi ta kasa da kasa Journal Journal of the National Academy of Sciences. Gabaɗaya, lokacin da zafin batirin lithium-ion abin hawa na al’ada ya yi ƙasa da 10 ℃, ions lithium a cikin baturin za su taru su ajiye a carbon cathode, yana haifar da ƙarin cajin lokaci da attenuation na ƙarfin baturi.

Wannan sakamakon binciken zai iya fahimtar minti 15 na caji kowane lokaci a 0 ℃, tabbatar da hawan keke na 4500 kuma kawai 20% iya aiki. A ƙarƙashin yanayi guda, baturin lithium-ion na al’ada zai sami ƙarfin ƙarfin 20% bayan zagayowar 50. An fahimci cewa wannan sabon baturi na lithium-ion yana ƙara ɓangarorin siriri na nickel da na’urar gano yanayin zafi bisa tushen batirin lithium-ion na gargajiya don tabbatar da cewa electrons na iya samar da hanya ta cikin takardar nickel lokacin da zafin baturin ya yi ƙasa da ƙasa. zafin dakin. Ta hanyar juriya na thermal sakamako na karfe nickel, halin yanzu na iya zafi da bakin ciki takardar nickel. Da zarar zafin baturi ya hauhawa, zai fara amsawa ta atomatik na baturin lithium-ion kuma zai dawo da cajin al’ada da fitar da makamashi. Masu binciken sun ce samfurin gwajin na yanzu zai iya samar da ingantattun ra’ayoyi ga masu kera batirin lithium-ion don amfani da motocin lantarki ba tare da cutar da zafin waje ba ko da a wuraren sanyi.
