As carbon peak and carbon neutral become a global consensus, the proportion of new energy in the entire energy system will rapidly increase. However, due to the natural instability of renewable energy such as wind power and photovoltaic power generation, supporting energy storage is required to eliminate peak valley differences in power, achieve smooth output, peak shaving, frequency modulation, and standby capacity of new energy such as photovoltaic and wind power, and meet the smooth access of new energy power generation to the grid, Large-scale energy storage batteries are one of the important means to solve the problem of grid connection and consumption of renewable energy.

Policy support

In recent years, China's policies have strongly supported the development of energy storage batteries. The Guiding Opinions on Accelerating the Development of New Energy Storage Technologies propose to adhere to the diversification of energy storage technologies, and promote the continuous decline in the cost and commercialization of relatively mature new energy storage technologies such as lithium ion batteries. With favorable policies, it is expected that the rapid development of energy storage batteries will help China achieve the goal of carbon neutrality.

Battery costs have decreased

The rapid growth of renewable energy power system construction has laid the foundation for the deployment of large-scale energy storage systems. At the same time, technological progress and the expansion of production scale have driven down the cost of energy storage batteries. In addition, the rapid development of the power battery industry has also led to the application of related technologies in energy storage batteries, driving down the cost of energy storage batteries. As the cost of energy storage batteries continues to decline, the energy storage battery market will usher in a stage of rapid development and large-scale development, which will help China's energy low-carbon transformation.

Battery performance upgrade

Lithium battery has high single voltage, wide operating temperature range, high energy density and efficiency, and low self-discharge rate. The use of protection and equalization circuits can improve safety and life. At the same time, the lithium battery industry chain is relatively mature, stable, reliable, and environmentally friendly, helping energy storage batteries achieve China's "dual carbon" plan.
