How do you build a Li-ion battery pack?

Building a Li-ion battery pack begins by satisfying voltage and runtime requirements, and then taking loading, environmental, size and weight limitations into account. Portable designs for consumer products want a slim profile and the choice is a prismatic or pouch cell.

What is a Li-ion battery pack?

At the base of every Li-ion battery pack is the battery cell or cells. A pack can contain one cell or many cells configured to achieve higher capacity or output voltage. This is achieved by connecting cells in parallel or series, and we'll explore this much further in our next blog.

What is a Li-ion battery?

We’ve already provided some basics about Li-ion cells in our previous blog posts, including different form factors and chemistry types. At the base of every Li-ion battery pack is the battery cell or cells. A pack can contain one cell or many cells configured to achieve higher capacity or output voltage.

What are the components of a lithium ion battery?

A lithium-ion battery is composed of many individual cells. Each of these cells always has the same structure and contains the following components: Positive electrode: The cathode of the lithium-ion battery consists of lithium metal oxide, which may contain variable amounts of nickel, manganese and cobalt.

What is Li-ion battery 101?

Welcome back to Li-ion Battery 101! So far, the blogs in this series have covered a variety of topics related to Li-ion batteries at the cell level. Li-ion cells are the basic building blocks for Li-ion battery packs which can consist of one or more cells and other components.

What is the difference between 18650 and AA batteries?

The 18650 (18mm diameter and 65mm length ) battery is a size classification of lithium-ion batteries. It is the same shape, but a bit larger than a AA battery. AA batteries, by comparison, are sometimes called 14500 batteries because they have a 14mm diameter and 50mm height.
