Lithium battery energy storage is still mainstream

         Lithium battery energy storage occupies more than 90% market share in the current new energy storage, which is the mainstream technology route. For lithium battery energy storage, extending battery life and reducing capacity degradation is an important technical breakthrough direction. The reporter learned at the summit that lithium replenishment technology is becoming a means of solving the above problems. Lithium-ion battery life of about 15 years, less than one-third of the traditional pumped storage life of 50 years, but also lower than the power industry core components of the design standard of 20 years of life. Therefore, lithium batteries for energy storage urgently need to further break through the life bottleneck.
          Energy storage market, there are diversified technology routes are competing with lithium-ion battery technology routes. With lithium-ion battery principle is basically the same as the sodium-ion battery is one of them.
　　In the first half of 2024, sodium-ion battery energy storage projects frequently landed. in May, the world's first set of 10MWh sodium-ion battery grid-side energy storage system officially put into operation in nanning, guangxi. on June 30, datang hubei 100MW/200MWh sodium-ion new energy storage power plant science and technology innovation demonstration project phase i project was completed and put into operation, put into operation 50MW/100MWh. this is the world's largest sodium-ion battery energy storage projects. sodium-ion battery energy storage project in the world.
         The commercial operation of sodium-ion battery energy storage has entered a new stage. Sodium-ion battery is a key supporting technology for China to build a new type of power system and an important direction to cultivate strategic emerging industries.
