Kugwiritsa ntchito kwa mabatire a lithiamu-ionzasintha kwambiri moyo wa anthu. Komabe, ndi chitukuko chofulumira cha anthu amakono, anthu akufuna kuthamanga kwambiri komanso kuthamanga kwapamwamba, kotero kafukufuku wokhudza kuthamanga kwachangu kwa mabatire a lithiamu-ion ndi ofunika kwambiri. Izi mkulu-mphamvu-kachulukidwebatri ya lithiamu-ionukadaulo wothamangitsa mwachangu udzakhala ndi mwayi wogwiritsa ntchito zida zamagetsi zam'manja, zida zamagetsi zamphamvu kwambiri, ndi magalimoto amagetsi. Komabe, kafukufuku wapano wothamangitsa mwachangu walepheretsedwa ndi zopinga zambiri, monga kusinthika kwa lithiamu kumbali yolakwika ya elekitirodi. Kuti tiwongolere kuthamangitsa mwachangu kwa mabatire a lithiamu-ion, tiyenera kumvetsetsa bwino kusintha kwa zinthu za elekitirodi panthawi yabwino komanso yoyipa.

Posachedwapa, Dr. Tanvir R. Tanim wochokera ku United States adafalitsa zolemba zokhudzana ndi kafukufuku. Nkhaniyi ikuphatikiza kusanthula kwa electrochemical, zitsanzo zolephera komanso mawonekedwe pambuyo poyesedwa kuti aphunzire za kuyitanitsa mwachangu (XFC) pazinthu za cathode pamasikelo angapo. Zitsanzo zoyeserera zikuphatikiza 41 G/NMCmabatire a thumba. Kuthamanga kwachangu (1-9 C) ndikuzungulira mpaka nthawi 1000 poyang'anira boma. Anapeza kuti m'zaka za mkombero oyambirira vuto la elekitirodi zabwino anali laling'ono kwambiri, koma pa mapeto a moyo batire, ndi elekitirodi zabwino anaonekera ming'alu zoonekeratu ndi limodzi ndi limagwirira kutopa, zabwino elekitirodi kulephera anayamba imathandizira. Panthawi yozungulira, mawonekedwe akuluakulu a electrode abwino amakhalabe osasunthika, koma zikhoza kuwonedwa kuti tinthu tating'onoting'ono tating'ono tating'ono tating'ono tapangidwanso kwambiri.

Kupyolera mu kusanthula, zikhoza kupezeka kuti ngakhale pa mlingo wochepa kwambiri, kuzama kwapamwamba kwambiri kudzachititsa kuti cathode iwonongeke. Izi ndichifukwa choti kuzama kwachabechabe kumapangitsa kuti kupsinjika komwe kumapangidwa mkati mwa tinthu tating'onoting'ono ta elekitirodi kuchuluke, kotero kuti kupindika komwe kumadutsako kumakhalanso kwakukulu, zomwe zimapangitsa kuwonongeka kwakukulu pakazungulira.
