Energy storage battery technology is one of the most important technologies in the field of renewable energy, and its development will have a profound impact on future energy storage. With the widespread application of renewable energy, energy storage battery technology is also constantly developing, and it will become a mainstream energy storage technology in the future.

The development trend of energy storage battery technology includes the following aspects:

(1) An increase in energy density. Energy density refers to the energy stored per unit volume or weight of a battery. With the continuous development of energy storage battery technology, the improvement of energy density will become an important development trend of energy storage battery technology. The energy density of future energy storage batteries should be able to be increased to a sufficiently high level to meet the needs of various application scenarios.

(2) Improved security. Energy storage battery technology may be affected by various factors during the process of storing energy, such as overcharging, discharging, short circuits, etc. Therefore, the improvement of the safety of energy storage battery technology will become an important development trend.

(3) Improvement of environmental friendliness. Energy storage battery technology may generate some pollutants such as carbon dioxide, mercury, etc. during the process of storing energy. Therefore, the improvement of environmental friendliness in energy storage battery technology will become an important development trend.
