Codsiga ee baytariyada lithium-ionayaa si weyn u wanaajisay qaab nololeedka dadka. Si kastaba ha noqotee, horumarka degdega ah ee bulshada casriga ah, dadku waxay dalbanayaan xawaare sare oo sarreeya, sidaas darteed cilmi baarista ku dallacaadda degdegga ah ee baytariyada lithium-ion waa mid aad muhiim u ah. Cufnaantan-tamarta-sarebaytari lithium-ionTignoolajiyada dallacaadda degdega ah waxay yeelan doontaa rajooyin ballaadhan oo ku saabsan aaladaha elektiroonigga ah ee mobilada, aaladaha korantada ee awoodda sare leh, iyo baabuurta korantada. Si kastaba ha ahaatee, cilmi-baarista degdegga ah ee hadda jirta waxaa hor istaagay caqabado badan, sida horumarinta lithium ee dhinaca korantada taban. Si loo hagaajiyo waxqabadka degdega ah ee ku dallaca baytariyada lithium-ion, waa in aan si buuxda u fahamsanahay isbeddelada qalabka electrode inta lagu jiro hababka togan iyo kuwa taban.

Dhawaan, Dr. Tanvir R. Tanim oo u dhashay Maraykanka ayaa daabacay waraaqo cilmi-baaris oo la xidhiidha. Maqaalkani waxa uu isku daraa falanqaynta korantada, moodooyinka guuldarada iyo sifada ka dib marka la tijaabiyo si loo darso saamaynta ku dallacaadda degdega ah (XFC) ee walxaha cathode ee miisaanyo badan. Tusaalooyinka tijaabada ah waxaa ka mid ah 41 G/NMCbaytariyada boorsada. Sicirka dallaca degdega ah (1-9 C) oo wareeg ilaa 1000 jeer gobolka masuulka. Waxaa la ogaaday in inta lagu guda jiro wareegga hore, dhibaatada electrode togan uu ahaa mid aad u yar, laakiin dhamaadka nolosha batteriga, electrode wanaagsan u muuqday dildilaaca cad oo ay la socdaan habka daalka, failure electrode togan bilaabay inuu dardar. Inta lagu jiro wareegga, qaabka ugu muhiimsan ee korantada togan ayaa weli ah mid sax ah, laakiin waxaa la ogaan karaa in qaybaha dusha sare ay si weyn u habeeyeen.

Falanqaynta, waxaa la ogaan karaa in xitaa heer aad u hooseeya, qoto dheer oo sarreeya ayaa sababi doona awoodda cathode inay hoos u dhacdo. Tani waxay u badan tahay sababtoo ah qoto dheer ee dallacadu waxay sababtaa walbahaarka ka soo baxa gudaha walxaha elektiroonigga ah inay kordhaan, sidaas darteed qallafsanaanta ay ku dhacdo ayaa sidoo kale ka weyn, taasoo keentay dhaawac weyn oo wareeg ah.
