Kupita patsogolo kwaukadaulo mu mabatire a lithiamu-ion kwachedwa.Pakali pano, mabatire a lithiamu-ion ndi apamwamba kwambiri kuposa mabatire a lead-acid ndi nickel-metal hydride potengera kuchuluka kwa mphamvu, mawonekedwe apamwamba ndi otsika kutentha, komanso magwiridwe antchito ochulukitsa, komabe zimakhala zovuta kukwaniritsa kufunikira kwamphamvu kwazinthu zamagetsi. ndi magalimoto amagetsi.M'zaka zaposachedwapa, ochita kafukufuku agwira ntchito kuti apititse patsogolo mphamvu zowonjezera mphamvu (volume-to-volume ratio), mtengo, chitetezo, zotsatira za chilengedwe ndi moyo woyesera wa mabatire a lithiamu-ion, ndipo akupanga mitundu yatsopano ya mabatire.Koma Patherini akuti ukadaulo wa batri wa lithiamu-ion tsopano watsala pang'ono kutha, ndipo malo oti apititse patsogolo ndi ochepa.
Asayansi tsopano akugwira ntchito pa mabatire atsopano omwe ali ndi mphamvu zambiri zosungirako mphamvu komanso nthawi yayitali ya moyo, makamaka m'madera osiyanasiyana, chifukwa palibe amene ali oyenera minda yonse. chitukuko cha luso lamakono.Iwo ndi opepuka komanso okhalitsa, ndipo ali ndi phindu losayerekezeka pa chitukuko cha teknoloji ya ogula ma drone.
Osati kale kwambiri, asayansi aku China adapanga batri ya lithiamu-ion yomwe ingagwiritsidwe ntchito pa madigiri 70 Celsius, yomwe ingagwiritsidwe ntchito m'madera ozizira kwambiri komanso ngakhale kunja, zomwe zimamveka ngati tsiku loopsya. Malinga ndi ofufuza, atsopano batire ndi yotsika mtengo komanso yogwirizana ndi chilengedwe, koma nthawi yofunika kuti ikhale yogulitsa ndi yakuti mphamvu zake zimakhala zochepa kwambiri kuti zigwirizane ndi mabatire a lithiamu-ion.
Posachedwapa, luso lamakono mu gawo la batri. Gulu lofufuza pa yunivesite ya Harvard lapanga mtundu watsopano wa batire yothamanga pogwiritsa ntchito electrolyte yomwe ili yopanda poizoni, yosawononga, pH-neutral, ndipo imakhala ndi moyo wa zaka zoposa 10. Gululi akuti batire yothamanga ingagwiritsidwe ntchito osati mu mafoni a m'manja okha, komanso muzogwiritsira ntchito mphamvu zatsopano, kuphatikizapo mphamvu zowonjezereka, ndi chitetezo chabwino komanso moyo wautali kusiyana ndi zinthu zamakono zamakono, gululo linati.

Batire yamtundu wina wapanganso luso laukadaulo.Mtundu watsopano wa batri yolimba-boma ukupangidwa.Batire yolimba-boma ndi yaying'ono kuposa mabatire amtundu wa lithiamu-ion, electrode yolimba ndi electrolyte yolimba, yokhala ndi mphamvu zochepa, mphamvu zambiri. kachulukidwe, mphamvu yomweyo, voliyumu ya batri yolimba ndi yaying'ono kuposa mabatire a lithiamu-ion wamba.
