List and comparison of 18650 and other small cylindrical Li-Ion cells

WE DO NOT SELL THESE CELLS

This is a list of sources for some 500 different small cylindrical Li-Ion battery cells of any chemistry: LiFePO4, NMC, LiCo, etc.

This information does not constitute an endorsement of any of these companies and products.

While the information presented here is believed to be accurate, this site takes no responsibility for any errors.

Please send us comments, corrections and additions.

Most of these data come from Henrik K. Jensen's great site FlashLight information, and specifically the cell comparator.

The rest of the data are from testing done at Elithion or from the manufacturer's published spec sheets. Unlike the sources of data listed above, this page gives practical tools to select cells for power applications, energy applications, or both; it does so by listing the Short Discharge Time and Energy Density of the cells. Modified Ragone Chart This chart (similar to a Ragone chart, except that it uses Short Discharge Time instead of Power Density) displays all the cells, color coded by use: Power: cells with a SDT less than 55 s; these cells are ideal for a high power battery (high power but low energy)

Energy: cells with a SDT between 120 and 250 s, and a Energy Density higer than 600 Wh/l; these cells are ideal for a high power battery (high energy but low power)

Both: cells that have a ratio of SDT / ED above 5, and are not already included in the above sets; these cells offer a good compromise between energy and power

Mediocre: cells that have a ratio of SDT / ED above 2, and are not already included in the above sets; low performance, but acceptable

Inadequate: all other cells; not recommended at all

Best cells for power along the left edge; best cells for energy in the middle of the top edge; best cells for both along the top-left diagonal Best cells for power along the left edge; best cells for energy in the middle of the top edge; best cells for both along the top-left diagonal

Energy cells

These are small cylindrical cells with the highest Energy Density.

They are ideal for energy batteries: slow discharge, highest possible energy

Highest energy density (best) first
