Battery energy storage is widely used in power generation, transmission, distribution and utilization of power system . In recent years, the use of large-scale energy storage power supply to participate in power grid frequency regulation has been widely concerned.
For electrochemical energy storage, the specific energy and specific power are two important parameters. Other important parameters are ability to charge and discharge a large number of times, to retain charge as long time as possible and ability to charge and discharge over a wide range of temperatures.
The growing popularity of electric vehicles requires greater energy and power requirements—including extreme-fast charge capabilities —from the batteries that drive them. In addition, stationary battery energy storage systems are critical to ensuring that power from renewable energy sources is available when and where it is needed.
