To understand the similarities and differences between Lithium and Lithium-ion batteries, you need a basic understanding of what constitutes a battery, and how they work. All batteries are made up of the same three basic components; the anode (negative - side), the cathode (positive + side), and some sort of electrolyte. When the cathode and anode of a battery are connected to an electrical circuit, a chemical reaction occurs between the anode and electrolyte.
