Enkulaakulana eyaakakolebwa mu nkola z’okuzuula, enkola y’okucaajinga mu ngeri ey’amagezi, n’ebintu ebirongooseddwa bifunza ekituli wakati w’ebyo abakozesa bye baagala n’ebyo bbaatule bye zisobola okutuusa obulungi. Real-Time plating detection achieving 99% accuracy, nga egattibwa wamu ne adaptive charging protocols, kitegeeza nti batteries kati zisobola okusemberera ekkomo lyazo ery’omubiri okumpi awatali kusala mu territory ya bulabe.

Ku muntu yenna akola ne bbaatule za lithium-ion-ka kibeere mu Ebikes, Smartphones, oba mmotoka ez'amasannyalaze-Okutegeera Lithium plating kiwa amagezi lwaki bbaatule zeeyisa nga bwe zikola. Ebyo ebikoma ku vvulovumenti, okuziyiza sipiidi y’okucaajinga, n’okulabula kw’ebbugumu biriwo olw’ensonga z’amasannyalaze ennywevu, okukuuma eby’obugagga bya lithium ebisalawo ebbanga bbaatule yo ly’eneekuweereza.
