Large-scale energy storage capacity for the development of new energy is essential, lithium-ion batteries has a very good application prospects in the field of large-scale storage． First of all, it can solve the problem of peak-valley regulation of grid electricity consumption. Secondly, clean energy sources such as wind energy, solar energy and tidal energy are intermittent energy sources. Lithium energy storage equipment cooperates with the above clean energy sources，energy storage while generating electricity, release energy during breaks, can effectively ease the current situation of China's energy shortage.
Energy storage technology has certain application prospects in improving the utilization of renewable energy and all aspects of the power system. It relieves the power supply voltage, improves the stability of the power system and improves the power supply quality. Our lithium-ion battery have the advantage of high energy density and high power, is the development potential of the battery system, widely used in new energy power and other fields.
