Orginal Compact Ebike Battery 25Ah For Long Service Life Outdoor

Lithium-ion batteries use lithium ions as carriers. During charging and discharging, they carry electrons to the positive or negative electrodes. Lithium ions always carry a positive charge. The positive electrode is composed of lithium and CoO2 (cobalt dioxide), while the negative electrode is composed of carbon (carbon). During charging, under an applied potential, the negative electrode receives X charged lithium ions, transforming them into LixCn. The positive electrode remains unchanged, but loses X charged lithium ions.
