With the increasing global emphasis on renewable energy, the importance of energy storage systems is becoming increasingly prominent. Recently, an energy storage battery using microporous carbon coated copper foil performed well in grid stability testing and successfully passed multiple rigorous tests. This battery not only has higher energy storage capacity, but also can quickly respond to grid fluctuations, providing stable power support for the grid. Industry insiders say that the application of microporous carbon coated copper foil will bring a technological revolution to the energy storage field.
