- Creating a new benchmark for long-life lithium battery energy storage: global debut of EVE Energy's Mr. Flagship series

HUIZHOU, China, Jan. 26, 2024/PRNewswire/ -- Under the global commitment to achieving peak carbon and carbon neutrality, the demand for large-scale and long-duration energy storage has become more prominent.

EVE Energy introduced its CTT technology in October 2022 and is one of the pioneers in the field of long-life lithium battery energy storage.

How to achieve a breakthrough in energy storage in long-life lithium batteries? On January 25, 2024, EVE Energy held an online launch conference for its Mr. Flagship series with the theme "Reliable Energy Storage with EVE Energy Big Batteries", introducing its Mr. Big battery cell and system. Mr. Giant.

The Mr. Big battery cell has a high capacity of up to 628 Ah and employs third-generation high-speed stacking technology, enabling 96% energy efficiency. The Mr. Giant system uses a standard 20-foot container, providing a power capacity of 5 MWh and a high energy efficiency of 95%.

Dr. Yuan Dingding, Chief Technology Officer of EVE Energy LFP Battery Division, explained that the newly launched Mr. Flagship series is based on electrochemical theories and technology and incorporates innovative technologies such as current harvesting, 3T technology and separator. of 14 μm, allowing minimal heat loss between charge and discharge cycles, and the products are "more efficient, simpler and safer", bringing a new definition of ESS (energy storage systems) and satisfying effectively meet the needs of the development of large-scale, long-duration energy storage.

According to calculations, a 1% increase in energy efficiency will result in an increase of RMB 3.6 million in customers' operating income over the entire life cycle.

To improve energy efficiency and improve customer profitability, EVE Energy R&D team maintains the research spirit of scientists and takes the lead in creating an innovative electrochemical current harvesting model in the industry based on the principle of electrochemistry. In this process, EVE Energy's R&D team created battery tabs and posts with "golden section ratio" positions and sizes, just as opening a "highway" for electronics, achieving a breakthrough in energy efficiency.

"The battery has its vitality and we always make each battery with reverence." This is the corporate culture of EVE Energy.

To solve the problem of temperature uniformity in a large battery volume space, EVE Energy invented 3T technology, which is one of the core technologies of Mr. Flagship series.

According to Yuan Dingding, the inspiration for the revolutionary 3T technology came from the science fiction classic The Three-Body Problem. In the book, there is a weapon called a two-dimensional sheet, which causes three-dimensional space to collapse into two-dimensional space. This idea inspired the R&D team.

EVE Energy incorporated "two-dimensional sheet" devices into its batteries to convert thermal diffusion in three-dimensional space during the batteries' charge-discharge cycle into heat exchange in two-dimensional space. It successfully solved the problem of heat generation with large capacity batteries and improved the energy efficiency of batteries and systems.

3T technology has reduced the temperature difference from 8°C to 1.5°C for Mr. Big batteries. It allows Mr. Giant systems to have up to 95% energy efficiency, with controlled temperature differences below 3°C and a 5°C decrease in maximum temperature.

With continued advancements in lithium battery technologies, optimized energy storage solutions will unleash the full potential of photovoltaics, ensure stable power supply during the day and night, and contribute to the restoration of the Earth.

Built on the reverence for batteries, EVE Energy consistently adheres to its original aspiration and approaches each product seriously.

Compared to the common 314 Ah solution, the Mr. Big integrated system with a capacity of 628 Ah has reduced the number of battery cells by 50%; In terms of package design, the comprehensive large package design has been adopted to reduce welding points, steel strips and end plates by 50%; At the system level, the number of information collection points and cables has been reduced by 50%.

Process innovation has always been at the center of EVE Energy's technological innovation. For example, the 14 μm spacers selected by EVE Energy for its Mr. Flagship series have a thickness that far exceeds the industry standard and significantly improves battery safety performance.

According to Yuan Dingding, this special coated separator technology has excellent thermal quenching effect. When the temperature reaches a critical value, the coating particles will melt and prevent potential dangers. In addition, a coating is made on both sides to guarantee greater safety of the separators.

As the first company to introduce and achieve rapid mass production of the Mr. Flagship series, EVE Energy has experienced a substantial leap in energy storage battery technology. This breakthrough will effectively drive the transformation of society towards a cleaner, more efficient and sustainable energy storage era and further lead the world towards the era of large-scale energy storage.
