How is a lithium ion battery made?

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.
