Lithium-ion cells used in electric car batteries have two electrodes – positive and negative. They are separated by an electrolyte in the form of liquid, gel or solid, which function is to transfer charges between them. Lithium-ion batteries available on the market may vary in chemical composition and design; however charge carriers are always lithium ions. Their manufacturers are still working on increasing energy density, widening the range of operating temperature, shortening the charging time and, above all, improving operational safety.
