Difference Between Power Lithium Battery and Energy Storage Lithium Battery

At present, low-carbon has become the main development direction of the world, and the demand for lithium batteries is rising with the support of national policies. With the gradual maturity of lithium battery technology, according to the differences in battery application scenarios, lithium batteries on the market are mainly divided into two categories: power batteries and energy storage batteries.

What is a power battery? 
 

Power batteries are mostly used in new energy vehicles, electric trains, light electric vehicles, etc., and are lithium batteries that provide power for these vehicles.

What is an energy storage battery?
 

Energy storage batteries are often used in household energy storage, solar and wind power plants, portable power supplies, communication base stations, etc., and renewable energy storage batteries.

The main difference between power lithium batteries and energy storage lithium batteries is that their design and use are different.

Power lithium batteries are generally used to provide high power output, such as electric vehicles, hybrid vehicles, and so on. This type of battery needs to have the characteristics of high energy density, high discharge rate, and long life to adapt to the high-intensity charge-discharge cycle.

Energy storage lithium batteries are used for long-term storage of energy, such as solar power generation systems, wind power generation systems, etc. This type of battery requires a higher energy density and lower cost to meet the needs of the energy storage system and is generally required to have a long life and a lower self-discharge rate.

Therefore, although both types of lithium batteries use lithium ions as electrolytes, their design and performance indicators are different in adapting to different application scenarios.

Power lithium batteries are generally used in scenarios that require high power output:

1, electric vehicles, hybrid vehicles, and other transportation driving energy;

2, power tools, drones, and other portable equipment power sources.

Energy storage lithium batteries are used in scenarios that require long-term energy storage:

1, solar photovoltaic power generation system, wind power generation system, and other distributed energy system energy storage equipment;

2, power grid peak energy storage, emergency backup power supply, and other industrial and civil energy storage equipment.

In addition, with the continuous progress of technology and the continuous expansion of application scenarios, power lithium batteries have also begun to be applied to some lower-power scenarios, such as smart homes, the Internet of Things, and other fields, while lithium energy storage batteries are also gradually expanding their application range, such as the secondary utilization of electric vehicles, graphene-enhanced lithium-ion batteries, and other new materials.
