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.
What are some common uses of 21700 batteries?
21700 battery is one of the most popular and commonly found cells in the battery pack in electric vehicles, battery-powered construction equipment, portable power cutting/drilling tools, the emergency torch, flashlight, etc. after 18650 battery cells.
How big should a 21700 battery cell be?
The 21700 cell by definition should be 21mm in diameter and 70mm high. Clearly the cell sizes are quite variable. Plotting the volume lines onto this shows that the cells have a trendline of increasing diameter and hencing increasing the volume by up to 10%.
