Inqubekelaphambili yezobuchwepheshe kumabhethri e-lithium-ion ihambe kancane.Njengamanje, amabhethri e-lithium-ion aphakeme kakhulu kunamabhethri e-lead-acid kanye ne-nickel-metal hydride ngokwenani lamandla, izici zokushisa eziphakeme neziphansi, nokusebenza okuphindaphindekayo, kodwa kusenzima ukuhlangabezana nesidingo esikhuphuka ngokushesha semikhiqizo kagesi. kanye nezimoto zikagesi.Eminyakeni yamuva nje, abacwaningi baye basebenzela ukuthuthukisa ukuminyana kwamandla (i-volume-to-volume ratio), inani, ukuphepha, umthelela wemvelo kanye nempilo yesilingo yamabhethri e-lithium-ion, futhi baklama izinhlobo ezintsha zamabhethri.Kodwa i-Patherini ithi ubuchwepheshe bebhethri ye-lithium-ion bendabuko manje sebusondela ekuvinjweni, futhi isikhala sokwenza okwengeziwe silinganiselwe.
Ososayensi manje basebenzela amabhethri amasha anokugcina amandla amaningi nempilo ende, ikakhulukazi emikhakheni ehlukene, ngoba ayikho efanelekile kuzo zonke izinkambu.Esimeni samanje sokuthuthukiswa kobuchwepheshe bebhethri ye-lithium-ion, ibhethri ye-lithium-ion inomthelela ukuthuthukiswa kobuchwepheshe obusha.Zilula futhi zihlala isikhathi eside, futhi zinenani elingenakulinganiswa ekuthuthukisweni kobuchwepheshe babathengi be-drone.
Esikhathini esingeside esidlule, ososayensi baseShayina bathuthukise ibhethri ye-lithium-ion engasetshenziswa ku-minus 70 degrees Celsius, engasetshenziswa ezindaweni ezibandayo kakhulu ngisho nasemkhathini, okuzwakala njengosuku olusabekayo.Ngokocwaningo, entsha ibhethri alibizi futhi lihambisana nemvelo, kodwa isikhathi esibalulekile sokutholakala kwezentengiso ukuthi ukuminyana kwamandla alo kuphansi kakhulu ukuze kufane namabhethri e-lithium-ion endabuko.
Muva nje, ukusungulwa okusha kwezobuchwepheshe emkhakheni webhethri.Ithimba labacwaningi eNyuvesi yaseHarvard lenze uhlobo olusha lwebhethri eligelezayo lisebenzisa i-electrolyte engenabo ubuthi, engagqwali, engathathi hlangothi i-pH, futhi ephila iminyaka engaphezu kweyi-10. Ithimba ithi ibhethri lokugeleza lingasetshenziswa hhayi kuphela kuma-smartphones, kodwa nasezinhlelweni ezintsha zamandla, okuhlanganisa amandla avuselelekayo, ngokuphepha okungcono nokuphila isikhathi eside kunemikhiqizo yebhethri yamanje, kusho ithimba.

Olunye uhlobo lwebhethri nalo lenze impumelelo kwezobuchwepheshe.Kuthuthukiswe uhlobo olusha lwebhethri yesimo esiqinile.Ibhethri lesimo esiqinile lincane kunamabhethri e-lithium-ion endabuko, i-electrode eqinile ne-electrolyte eqinile, enamandla aphansi, amandla aphezulu. ukuminyana, amandla afanayo, ivolumu yebhethri yesimo esiqinile incane kunamabhethri e-lithium-ion avamile.
