To review its structure more specifically, a battery cell can be further disassembled into the following components: Anode (Negative Electrode): Anode is typical made of lithium or

Battery Module: A group of interconnected battery cells that increases voltage and capacity compared to individual cells. It includes wiring and connectors and may feature a basic battery management system (BMS) for monitoring. Battery Pack: A complete energy storage system containing one or more modules.
In modern energy storage systems, batteries are structured into three key components: cells, modules, and packs. Each level of this structure plays a crucial role in delivering the performance, safety, and reliability demanded by various applications, including electric vehicles, renewable energy storage, and portable devices.
A lithium-ion battery pack is the largest and most complex assembly in the hierarchy of battery systems. It consists of multiple modules arranged in a specific configuration to meet the voltage and energy requirements of a particular application.
Lithium-ion battery cells come in three main formats: cylindrical, prismatic, and pouch cells. Cylindrical battery cells were the first lithium-ion batteries to achieve mass production. They’re made by winding the cathode, anode, and separator in a specific order into a cylinder shape and then housing it in a metal casing.
