With the rapid development of renewable energy, energy storage batteries are more and more widely used in them. Renewable energy sources such as wind and solar energy are intermittent and unstable, and energy storage batteries can store these unstable energy sources to achieve stable power supply. However, the application of energy storage batteries in the field of renewable energy also faces many challenges. On the one hand, the cost of energy storage batteries is still high, restricting its large-scale application in the field of renewable energy; On the other hand, the safety performance and life of energy storage batteries also need to be further solved. Nevertheless, with the continuous progress of technology and the reduction of costs, I believe that the application prospect of energy storage batteries in the field of renewable energy is still broad.
