Why 21700 Cells Are Replacing 18650 in Industrial Applications

The shift from 18650 to 21700 lithium cells represents a major technological evolution. 21700 batteries deliver higher capacity, lower internal resistance, and greater energy density, all within a slightly larger format. This upgrade provides equipment manufacturers with improved power efficiency and longer battery life. For industrial energy systems, e-mobility devices, and power tools, 21700 cells are rapidly becoming the new standard.
