I. Characteristics of energy storage batteries

Energy storage battery cells are battery components that can store large amounts of electrical energy and release it quickly. Different from traditional dry cell, lithium battery and other batteries, energy storage battery cell has the following characteristics:

1. high voltage, high current: energy storage batteries commonly used voltage of 3.2-3.7V, the current can reach hundreds of amperes.

2. long life: energy storage batteries have a long life, capable of charging and discharging thousands of times.

3. Large capacity: Energy storage batteries usually have a large amount of power, which can realize high power output for a long time.

II. The application areas of energy storage battery cells

Energy storage batteries have a wide range of applications, commonly used in new energy vehicles, energy storage equipment, UPS uninterruptible power supply and other fields. In the field of new energy vehicles, energy storage batteries are one of the core components of electric vehicles, and their performance directly affects the range and safety of the vehicle; in the field of energy storage equipment, energy storage batteries are usually used in solar energy storage systems, wind energy storage systems and so on.

III. Criteria for categorizing energy storage batteries

At present, there is no uniform regulation in the industry for the classification standard of energy storage battery cell. However, energy storage batteries are usually categorized into two types: power batteries and digital batteries.

1. power core, refers to the electric core that can withstand high current and high power output, widely used in new energy vehicles, energy storage power stations and other power areas.

2. Digital battery cell refers to the application scenario of low power and long endurance, which is usually used in the fields of smart home and consumer electronics.

IV. How to choose an energy storage battery cell

The categorization of energy storage batteries is directly related to their field of use and standards. When choosing energy storage battery cells, you need to choose according to the category and performance requirements of the desired application. If a high-performance high power output battery is required, the power cell should be selected; if the application scenario requires that the low-power state can be sustained power supply for a long time, the digital cell should be selected.

In conclusion, energy storage battery cells belong to both power battery cells and digital battery cells, and their categorization depends on the usage scenarios and industry standards. When choosing energy storage battery cells, it is necessary to make a reasonable choice according to its performance characteristics, use scenarios and standard requirements.

【Conclusion】 Through the discussion in this paper, we understand the characteristics, application areas and industry standards of energy storage battery cells, and analyze the question of whether energy storage battery cells belong to power battery cells or digital battery cells. In the actual application, reasonable selection should be made according to the characteristics of the energy storage battery cell and the use scene to meet the actual demand.
