How does a graphitic negative electrode work?
The copper collector of graphitic negative electrodes can dissolve during overdischarge and form microshorts on recharge. Preventing this is one of the functions of the battery management system (see 2.1.3). The electrode foils represent inert materials that reduce the energy density of the cell. Thus, they are made as thin as possible.
What are the components of a Li-ion battery?
A 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 Li-ion cells are the components that participate in the oxidation and reduction reactions.
