Learn MoreA Li-ion battery is composed of the active materials (negative electrode/positive electrode), the electrolyte, and the separator, which acts as a barrier between the negative electrode and positive electrode to avoid short circuits. The active materials in Liion cells are the components that - participate in the oxidation and reduction reactions.
Learn MoreIn general, an electrode is an electrical conductor which makes contact with a non-metallic part of a circuit. In a battery, the electrodes connect the battery terminals to the electrolyte. The electrode at the positive terminal is known as the cathode and the electrode at the negative terminal is known as the anode.
