Batteries are usually divided into two categories:
Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and non-aqueous electrolyte solutions.
Lithium ion batteries: Lithium ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and non-aqueous electrolytes.
Although lithium metal batteries have a high energy density, theoretically they can reach 3860 watts per kilogram. However, due to its unstable nature and inability to charge, it cannot be used as a power battery for repeated use. Lithium ion batteries have been developed as the main power battery due to their ability to be repeatedly charged. However, due to the combination of different elements, the performance of the positive electrode materials varies greatly, leading to increased disputes in the industry over the routes of positive electrode materials.
The most commonly mentioned power batteries are lithium iron phosphate batteries, lithium manganese oxide batteries, lithium cobalt oxide batteries, and ternary lithium batteries (ternary nickel cobalt manganese).
