Comparison of Lead-Acid to Lithium-ion in Stationary Storage Applications. Much wider temperature range than chemical batteries Operates at high temperatures: over 300 deg CĪvailable for utilities and large mini-grids Limited availability, mostly utility scale Laboratories developing versions safe at 55 deg C Battery Technologyġ,650 cycles at 50% DOD, 1050 cycles at 80% DODĬycle life degrades substantially above 25 deg C The following table outlines the cycle life, temperature sensitivity, round-trip efficiency, initial cost and specific energy of conventional, new and emerging battery technologies. ![]() ![]() Batteries that are more energy-dense reduce transportation costs and power-house size. ![]() Specific energy (in Wh/kg) is a measure of how much energy the battery can store per unit of mass.
