Fortunately [Adam Bender] is on hand with an extremely comprehensive two-part guide to designing and building lithium-ion battery packs from cylindrical 18650 cells. In one sense we think the two
Comparing 21700 vs 18650 lithium-ion battery cells, we find cordless power tools benefitting from more power density and better cooling tech.
The stronger heating and lower resistance of 21700 cells than the 18650 results in higher polarization in the 18650 and deviations between the voltage curves for the two formats at higher C rates. The 21700 has about 50% greater capacity and energy density than the 18650 for discharge rates up to about 3.75C.
The volumetric energy density and proportionately the specific energy have roughly doubled, through a combination of improved active materials and better engineering of the 18650 cell (Fig. 1). 10,11 Blomgren has provided an excellent review on the development and future of lithium-ion batteries. 12 In addition, Quinn et al. 13 and

18650 Battery. A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.. The cathode is made of a composite material (an intercalated lithium compound) and defines
