Lithium metal battery: A disposable battery typically consisting of lithium metal or lithium mixture as the anode.

Lithium ion batteries: Lithium ion batteries (abbreviated as Li ion batteries) are made by using a compound of lithium as the positive electrode, a carbon material that can embed and remove lithium ions instead of pure lithium as the negative electrode, and a mixed electrolyte as the electrolyte. It is a reusable battery commonly used in the consumer electronics industry.

Batteries produced from different lithium-ion battery cell materials can also be divided into polymer batteries, square type batteries, and cylindrical type batteries (usually 18650 cells).

The technical definitions of batteries and battery cells mentioned in the United Nations testing and standards manual are as follows:

A "battery" refers to two or more battery cells connected together by electrical circuits and equipped with necessary devices for use, such as a casing, electrode terminals, markings, and protective devices.

Single cell batteries are considered 'battery cells' (treated as battery cells during UN38.3 testing). A "battery cell" is a single, enclosed electrochemical device consisting of a positive electrode and a negative electrode, with a potential difference between the two electrodes. Regardless of whether they are referred to as "batteries" or "single cell batteries" outside of these rules and United Nations testing standards and manuals, they are referred to as "battery cells" rather than batteries in our rules and United Nations testing standards and manuals. In DGR, single cell batteries should be considered as battery cells rather than batteries for limitation.
