What is a 21700 lithium ion battery?
21700 Li-ion battery cells are a popular and relatively new standard for rechargeable lithium-ion batteries. Named after their dimensions (21mm in diameter and 70mm in length), these cells offer a larger capacity and higher energy density compared to the older 18650 format.
Are 21700 battery cells a good choice?
In the past two years, 21700 battery cells have gained widespread use in the small power market due to their higher energy density and overall cost advantages compared to traditional 18650 cells.
What are the advantages of using a 21700 battery?
The 21700 battery type is popular in rechargeable and high current draining devices considering its higher degree of capabilities like 1000+ charge cycle and higher energy density. When compared to AA size and 18650 type cells, their height and diameter both are larger. They are not replacements for AA or AAA or 18650 size cells.
What is the production capacity of 21700 battery cells?
This is especially evident in applications such as two-wheeled transportation, smart homes, power tools, consumer electronics, and portable energy storage. The capacity of 21700 battery cells has continuously broken through as their application scope expands. Currently, the highest production capacity available in the market is 21700-5.3Ah.
What is a 21700 cell?
For this article we will concentrate on the 21700 format, but this is migrating towards the 46mm diameter 46xx class of cylindrical cells in a push to reduce cell manufacturing costs. The 21700 cell increased the working volume over the 18650 by a factor of >1.4x 21700 => ~21mm in diameter and ~70.0mm long
What is the length of a 21700 battery?
The 21700 battery has an approximate length of 70mm. The diameter is 21mm, but technically 21700 cell size is allowed with some tolerance in length and diameter.
