Pakadali pano, lithiamu batri yamagetsi komanso yosungira mphamvu ya lithiamu imakhala yofunika kwambiri pamsika.

Pakadali pano, kugwiritsa ntchito ukadaulo wa lithiamu batire posungira mphamvu kumayang'ana kwambiri zamagawo amagetsi oyimitsira gridi, makina osungira kunyumba, magalimoto amagetsi ndi malo opangira zida zamagetsi, zida zamaofesi kunyumba ndi zina. Munthawi ya 13 ya Zaka Zisanu, msika wogulitsa magetsi ku China uzitsogolera pantchito zothandiza anthu, ndikulowerera kuchokera pakupanga magetsi ndikutumiza mbali kupita kwa wogwiritsa ntchito. Malinga ndi zomwe zidafotokozedwazi, kuchuluka kwa ntchito ya lithiamu batri yosungira magetsi mu 2017 inali pafupifupi 5.8gwh, ndipo gawo lamsika la batri ya lithiamu-ion lipitilizabe kukula chaka ndi chaka mu 2018.

Malinga ndi momwe ntchito imagwiritsidwira ntchito, mabatire a lithiamu-ion amatha kugawidwa pakugwiritsa ntchito, mphamvu ndi kusungira mphamvu. Pakadali pano, lithiamu batri yamagetsi komanso yosungira mphamvu ya lithiamu imakhala yofunika kwambiri pamsika. Malinga ndi kuneneratu kwa akatswiri odalirika, kuchuluka kwa batri ya lithiamu yamagetsi pamagetsi onse a lithiamu ku China akuyembekezeka kukwera mpaka 70% pofika 2020, ndipo batri lamagetsi ndi lomwe lidzagwiritse ntchito lifiyamu. Mphamvu ya lithiamu batri idzakhala mphamvu yayikulu ya lithiamu batri

Kukula mwachangu kwa mafakitale a lithiamu makamaka chifukwa cha mfundo zomwe zikulimbikitsa chitukuko chamakampani opanga magetsi. Mu Epulo 2017, Unduna wa zamakampani ndi ukadaulo wazidziwitso ku People's Republic of China udanenanso mu "pulani yapakatikati komanso yayitali yopanga magalimoto" kuti kupanga ndi kugulitsa magalimoto amagetsi atsopano kuyenera kufika 2 miliyoni mu 2020, ndi kuti magalimoto amagetsi atsopano ayenera kuwerengera zopitilira 20% zamagalimoto komanso kugulitsa pofika 2025. Zitha kuwonedwa kuti mphamvu zatsopano komanso kupulumutsa mphamvu zobiriwira ndi mafakitale ena oteteza zachilengedwe adzakhala mafakitole ofunikira m'mbuyomu.

Mukutengera kwamtsogolo kwaukadaulo wamagetsi wamagetsi, ternary ikukhala chizolowezi chachikulu. Poyerekeza ndi lithiamu cobalt oxide, lithiamu iron phosphate ndi lithiamu manganese dioxide mabatire, ternary lithiamu batri ali ndi mawonekedwe a mphamvu yayikulu, nsanja yamagetsi, kukwera kwapopopera, magwiridwe antchito oyenda bwino, kukhazikika kwamagetsi ndi zina zambiri. Ili ndi zabwino zowonekera pakukweza magalimoto atsopano amagetsi. Nthawi yomweyo, ilinso ndi maubwino amphamvu zotulutsa, magwiridwe antchito otentha otsika, ndipo imatha kusintha kutenthetsera nyengo. Pamagalimoto amagetsi, palibe kukayika kuti ogula ambiri ali ndi nkhawa ndi kupilira ndi chitetezo chake, ndipo batire ya lithiamu-ion mwachidziwikire ndi chisankho chabwino.

Ndi kuwonjezeka kofulumira kwa magalimoto amagetsi, kufunika kwa batire yama lithiamu-ion kwawonjezeka kwambiri, komwe kwakhala komwe kumayambitsa kukula kwa mafakitale a batri ya lithiamu-ion. Lithiamu batri ndichinthu chovuta kwambiri. Adabadwa mu 1980s ndipo adakhalapo nthawi yayitali yamvula komanso luso laumisiri. Nthawi yomweyo, ziribe kanthu kapangidwe kapena chiwonongeko cha lithiamu batri sichimavulaza chilengedwe, zomwe zikugwirizana kwambiri ndi zomwe zikuchitika pachitukuko cha anthu. Chifukwa chake, batire ya lithiamu yakhala chinthu chofunikira kwambiri m'badwo watsopano wamagetsi. M'masiku apakatikati, kukweza ukadaulo wapano pano ndiye maziko a kukweza ukadaulo wapadziko lonse lapansi. Monga chinthu chofunikira kwambiri chothandizira pakukweza ukadaulo waukadaulo, batire yama lithiamu yamagetsi ikuyenera kukhala ndi chitukuko chachikulu m'zaka zotsatira za 3-5.
