Lithium-ion batteries are easily confused with the following two types of batteries:

(1) Lithium battery: Use metal lithium as the negative electrode.

(2) Lithium-ion battery: Use non-aqueous liquid organic electrolyte.

(3) Lithium ion polymer battery: use polymer to gel liquid organic solvent, or directly use all solid electrolyte. Lithium-ion batteries generally use graphite-based carbon materials as the negative electrode.
