Lithium battery is currently the most common energy storage technology on the market. And the battery pack are widely used in various personal electronic products, mobile devices and electric vehicles battery.
Energy storage lithium battery is used in photovoltaics(PV) or UPS. Its internal resistance is relatively large, and the charging & discharging speed is relatively slow, generally 0.5~1C(50~100A).
Power lithium battery is generally used in electric vehicles. With low internal resistance and fast charging and discharging speed generally reach 3~5C(300~500A). And the price of power battery is about 1.5 times more expensive than energy storage batteries.
