EVE Energy To Mass Produce Large Battery Cell For Energy Storage

In the energy storage industry, both systems and battery cells are expanding at an astonishing pace. While the global market is rapidly adopting the 300Ah+ battery cells primarily based on 314Ah, research and mass production of the next-generation 500Ah+ large-capacity battery cells are already in full swing.

As many companies rush to enter the market for 500Ah+ large-capacity battery cells, EVE Energy has become the first in the industry to achieve mass production of the 628Ah large battery cell.

On December 10th, EVE Energy’s first phase of the 60GWh Super Energy Storage Factory, Mr. Big, officially commenced operations in Jingmen, Hubei.

The company said that by the end of the third quarter of 2024, EVE Energy’s global energy storage battery cell shipment volume had firmly secured the top 2 position. As the single largest energy storage factory and the first to mass-produce the 600Ah+ large battery cell, the achievements added new values to the firm. Over the past two years, large-capacity battery cells have undoubtedly emerged as a significant trend in the energy storage field.

In fact, as early as 2022, when the market was still promoting 280Ah battery cells, EVE Energy, leveraging its keen market insight and foresight, proposed the trend of large-capacity battery cell development and launched the 560Ah battery cell. Now, after more than a year of development, EVE Energy has upgraded the cell capacity to 628Ah.

Advantages of increased cell capacity 

The advantages of increasing cell capacity are clear: it can reduce the cost and integration complexity of energy storage systems, improve energy density and safety, and reduce the use of components in the PACK stage, thus simplifying the assembly process and further lowering costs.

However, challenges remain, particularly concerning thermal management and overall efficiency for large-capacity battery cells. To tackle these issues, EVE Energy partnered with Professor Yang Hanxi from Wuhan University, a top global university, to create an electrochemical collection model based on electrochemical principles. Inspired by the “low drag” design found in automotive engineering, the company continuously optimizes the thickness of the collection medium, the positioning of the tabs, and the shapes and sizes of the terminals, paving a high-speed road for electrons.

Technology to boost energy storage 

This technology employs intelligent high-precision source perception to capture key signals throughout the entire lifecycle of the battery cell in real-time. Similar to how smartwatches monitor blood oxygen and heart rate, this technology can monitor gases, temperatures, and other critical information in real time, effectively identifying parameters from different characteristics based on a powerful database matching mechanism and performing advanced processing and analysis on the signals.

Once an anomaly is detected, timely warnings and defensive measures are taken. The intelligent battery cell technology acts as a guardian of safety and will open a new track for battery safety in the energy storage industry.

To support the mass production of Mr. Big’s large battery cells, EVE Energy’s 60GWh Super Energy Storage Factory officially commenced operations on December 10th. EVE Energy has established a virtual factory leveraging digital twin technology, creating a super-intelligent factory that integrates automation, digitization, and low-carbon processes.
