5.Moemeli o thobang o mosehla
Li-ion tsa cationic ho lisebelisoa tse nolofatsang tse sebelisoang ha ho phetheloa liaparo li tla ba le oxidized ha li le tlas'a mocheso, leseli le maemo a mang.Seo se fella ka mosehla oa likarolo tse nolofatsang tsa lesela.
Le hoja mosehla o arotsoe ka mefuta e mehlano e boletsoeng ka holimo, ha e le hantle, liaparo tsa yellowing phenomenon hangata li bakoa ke mabaka a sa tšoaneng.
