What are cells, batteries, and battery packs?

Many friends who do not know about lithium battery well often ask me what are cells, batteries, and battery packs?

They generally think the battery pack produced by the battery manufacturer as a large battery. In fact, the lithium battery we use is actually the same as the lead-acid battery, the cells are obtained in parallel and/or in series.

Here let's introduce the concept of cells, batteries and battery packs.

Cell: the most basic element that makes up Batteries and a battery pack. Generally, the voltage can be supplied between 3v and 4v. For example, our VCELL lithium ion battery cell has LFP cell(3.2v) and NCM cell(3.6V).

Batteries: a collection of multiple cells that form a single physical module that provides higher voltage and capacity. For example, a battery module that uses four cells in series to provide a nominal 12V voltage, or multiple cells in parallel to provide greater capacity.

Battery pack: generally consists of a collection of multiple Batteries. At the same time, adding the battery management system (BMS), etc., which is the final product provided by the battery manufacturer to the user.

In addition, cells are generally divided into three types in a package: cylindrical, prismatic, and pouch.
