Information

The energy storage battery mainly provides electric energy storage and electric energy output. As the energy storage market where lithium batteries have not yet been greatly developed, what is the difference between the batteries used and power batteries? Can energy storage battery and power battery be used interchangeably? Although sometimes interchangeable, in fact it is not necessarily, and the specific situation needs to be analyzed in detail.

The general application scenarios of energy storage battery are the electricity consumption of some conventional electronic equipment, such as information base stations, some 3C electronic products, etc. Most of their discharge requirements are around 1C magnification. In this case, the battery used Material performance will be relatively poor. For example, in terms of separators, because low-rate discharge lithium batteries are not easy to generate heat, in terms of temperature resistance, separators will be worse than power batteries, and the price is relatively lower.

Furthermore, in terms of internal resistance, because the battery discharge current is small, energy storage batteries are generally larger than power batteries in terms of internal resistance.

In other words, although the energy storage battery and the power lithium battery use the same battery material type, the quality of the same material is slightly inferior to the energy storage lithium battery, and the internal resistance will be higher. Therefore, in terms of the overall price, generally speaking , Energy storage lithium iron phosphate batteries are cheaper than power lithium iron phosphate batteries.

Secondly, power batteries are used for energy storage.

After the design and configuration of the control system for the discharge size of the lithium battery, the lithium battery of the electric vehicle can be used as an energy storage battery. However, it may not be ideal in terms of economic benefits, after all, the cost of the battery and the cost of the power control system are high.

This is also one of the reasons why power batteries can be used in cascades.
