What are the types of cells used for energy storage batteries?

There are many types of energy storage cells, but here are some common ones:

1. Lithium-ion batteries: These are one of the most common and widely used Battery types, with advantages such as high energy density, long life and low self-discharge rate. Lithium-ion batteries are widely used in mobile devices, power tools and electric vehicles.

2. Nickel-Cadmium Battery : Nickel-cadmium batteries have high cycle life and good low temperature performance, but they contain harmful cadmium, and are gradually being phased out in some regions.

3. Nickel-Metal Hydride batteries: Nickel-metal hydride batteries are environmentally friendly energy storage batteries that do not contain the harmful substance cadmium, as opposed to nickel-cadmium batteries. However, NIMH batteries have a relatively low energy density.

4. Lead-Acid Battery: Lead-acid battery is a mature energy storage battery technology, mainly used in automotive starting, backup power and solar energy storage systems. It has low cost, high cycle life, but is larger and heavier.

5. Sodium-sulfur Battery: Sodium-sulfur battery is a high-temperature battery that uses the chemical reaction between Sodium and Sulfur compounds under high temperature conditions to store and release energy. Sodium-sulfur batteries have high energy density and long life, making them suitable for large-scale energy storage systems.

6. Sodium-ion batteries: Sodium-ion batteries are similar to lithium-ion batteries, but use Sodium ions as charge carriers. With relatively low cost and abundant resources, sodium-ion batteries are considered as potential candidates to replace lithium-ion batteries.

With the continuous progress of science and technology and research and development, new energy storage battery technologies are also emerging, and more types of cells may be developed and applied in the future.
