Lithium battery energy storage technology

Lithium-ion battery energy storage technology is important for the storage of electrical energy. The stored energy can be used as an emergency energy source, or it can be used to store energy when the grid load is low and output energy when the grid load is high, which can be used to cut peaks and fill valleys and mitigate grid fluctuations.

So far, for different fields and different needs, people have proposed and developed a variety of energy storage technologies to meet the application, and lithium-ion battery energy storage is currently the most feasible technical route.

In terms of the economics of energy storage technologies, lithium-ion batteries have a strong competitive edge, while sodium-sulfur batteries and vanadium-liquid flow batteries are not industrialized, have limited supply channels and are expensive. From the point of view of operation and maintenance costs, sodium-sulfur batteries to continuous heating, vanadium liquid flow batteries to pump for fluid control, added the cost of operation, while lithium-ion batteries almost do not maintain.

Public data show that China’s lithium-ion battery storage projects have 20, the total installed capacity of 39.575MW. energy storage is an important means to solve the intermittent volatility of new energy wind power, photovoltaic, peak shaving function, energy storage lithium-ion battery as an emerging application scenario is also gradually gaining attention.
