Lithium battery energy storage is the mainstream choice in the current new energy storage market. Lithium battery energy storage technology is constantly iterating, and lithium replenishment has become an important means to improve the shortcomings of battery life. New energy storage technologies such as sodium batteries and flow batteries are also attracting market attention. The fierce competition in lithium battery energy storage will naturally divert companies to non-lithium energy storage markets, especially long-term energy storage markets, to find opportunities. Lithium battery energy storage technology continues to improve Lithium battery energy storage accounts for more than 90% of the market share in the current new energy storage and is the mainstream technical route. For lithium battery energy storage, extending battery life and reducing capacity attenuation are important technical breakthrough directions. Reporters learned at the summit that lithium replenishment technology is becoming a means to solve the above problems.
