The electrical category is further divided into. . Electrochemical Li-ion Lead accumulator Sodium-sulphur battery . Electromagnetic Pumped storage Compressed air energy storage . When it comes to energy storage, there are specific application scenarios for generators, grids and consumers. Generators can use it to match production with. . Independent energy storage stations are a future trend among generators and grids in developing energy storage projects. They can be monitored and scheduled. [pdf]

These battery systems are based on lithium-ion technology and are widely used in modern data centers for power security and energy management due to their high energy density, long lifespan, and fast charging capability.. These battery systems are based on lithium-ion technology and are widely used in modern data centers for power security and energy management due to their high energy density, long lifespan, and fast charging capability.. The Data Center Li-ion Batteries mentioned in this report refer to the AC lithium-ion battery that is paired with UPS, which are specifically designed to provide power storage and backup power for data centers and critical power supply scenarios. These battery systems are based on lithium-ion. . The global data center energy storage market size was estimated at USD 1.58 billion in 2024 and is projected to reach USD 2.67 billion by 2030, growing at a CAGR of 9.5% from 2025 to 2030, driven by the exponential increase in data generation and digital transformation across industries.

Energy storage systems are designed to save energy for later use in order to assist load balancing, peak shaving and integration of renewable energy sources. Based on data centers, the data center battery market is segmented into enterprise data centers, colocation data centers, hyperscale data centers, and edge data centers.
Data centers are increasingly adopting renewable energy sources such as wind and sunlight to power their operations. Sophisticated battery storage systems are needed for this integration in order to regulate the intermittent behavior of renewable energy sources and ensure a constant and uninterrupted power supply.
The market for data center battery was valued at USD 3.4 billion in 2024 and is expected to reach around USD 5.9 billion by 2034, growing at 5.5% CAGR through 2034. Data center battery market was valued at USD 3.4 billion in 2024 and is estimated to grow at a CAGR of over 5.5% from 2025 to 2034 driven by growing advancements in battery technology.
Based on application, the data center battery market is segmented into uninterruptible power supply, backup power systems, energy storage systems, and peak shaving & load balancing. The uninterruptible power supply segment dominated the market with market share of 52% in 2024.
Data centers invest in advanced battery systems due to policies which promote the use of energy-efficient technologies and renewable energy sources. Businesses and governments are putting recycling systems into place to securely recycle spent batteries.
This creates the rising energy demands of data centers that are met by China's dominance in battery technology and manufacture, especially in lithium-ion batteries. For instance, according to Reuters, China has invested almost USD 6.12 billion in new data centers in 2022 and 2023.

Additionally, this study examines China's current state of energy storage technology based on authorized patents and explores its future development trends across electric energy storage systems (EESS), mechanical energy storage systems (MESS), chemical energy storage systems (CESS), thermal energy storage systems (TESS), and hydrogen-based energy storage systems (HESS).

China is gradually forming an open electricity sales market with diversified competitors. With ancillary services as the main base, the two-part tariff business model is used for electricity price incentives. Due to its flexibility, energy storage should be widely used in competitive models.
However, China's energy storage is developing rapidly. The government requires that some new units must be equipped with energy storage systems. The concept of shared energy storage has been applied in China, which effectively promotes the development of energy storage. 4.3. Explore new models of energy storage development
“The Energy Development Strategic Action Plan (2014∼2020)”, “Made in China 2025”, “Guiding Opinions on Smart Grid Development” and other documents have made plans for China's energy development, they emphasize that the development of energy storage and its application scenarios have become the key goal of system reform .
In October 2017, China's first guiding policy for developing large-scale energy storage technology and applications “Guiding Opinions on Promoting the Development of Energy Storage Industry and Technology” was officially released.
It also introduces the application scenarios of energy storage on the power generation side, transmission and distribution side, user side and microgrid of the power system in detail. Section 3 introduces six business models of energy storage in China and analyzes their practical applications.
In China, generation-side and grid-side energy storage dominate, making up 97% of newly deployed energy storage capacity in 2023. In China, generation-side and grid-side energy storage dominate, making up 97% of newly deployed energy storage capacity in 2023. 2023 was a breakthrough year for industrial and commercial energy storage in China.
