Lithium Ion Battery Energy Storage Systems Using 18650 Cells

Background Small cylindrical Li-ion cells (18650 cells) provide unmatched levels of energy density, specific energy, packaging flexibility, production quality, and safety. Several first-tier manufacturers now offer 18650 cells at or above 220 Wh/kg at cell prices below $280/kWh. The high production volume of these cells is projected to result in ongoing improvements in performance and […]
