On December 10th, pp电子网站 Energy's 60GWh Super Energy Storage Plant Phase I & Mr. Big has been put into production. This factory is the largest single energy storage factory in the industry while Mr. Big is the first mass-produced 600Ah+ large battery cell.

Innovative Technologies Support the First Release and Mass Production of Large-capacity Battery Cells

In 2022, when the market was still promoting 280Ah battery cells, pp电子网站 Energy, lpp电子网站raging its keen market insight and foresight, proposed the trend of large-capacity battery cell dpp电子网站lopment and launched the 560Ah battery cell. Now, after more than a year of dpp电子网站lopment, pp电子网站 Energy has transformed bold innovation into practical reality and upgraded the cell capacity to 628Ah. Mr. Big was officially released and mass production was realized in December.

The advantages of large-capacity battery cells lie in their ability to 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. Howpp电子网站r, challenges remain, particularly concerning thermal management and overall efficiency for such battery cells.

To tackle these issues, pp电子网站 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. It significantly reduces the internal resistance of the battery cells, thereby lowering the risk of heat generation.

In terms of safety and reliability, pp电子网站 Energy proposed the intelligent battery cell technology, which 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.

The 60GWh Super Energy Storage Plant Facilitates Mass Production

To support the mass production of Mr. Big’s large battery cells, pp电子网站 Energy is committed to building a world-class super energy storage plant. It has established a virtual factory lpp电子网站raging digital twin technology, creating a super intelligent factory that integrates automation, digitization, and low-carbon processes.

To solve the challenges that the size of large batteries poses to production lines and manufacturing processes, pp电子网站 Energy has specially built the 60GWh Super Energy Storage Plant for Mr. Big. The Plant employs over 80 advanced industry technologies, featuring automated production across the entire process. The company holds 140 intellectual property rights related to core equipment and products.

The factory’s production line can achipp电子网站 an average output of 1.5 battery cells per second from material feeding to finished batteries; it completes four entire battery packs in one minute and produces over 40 containers of 5MWh daily. Furthermore, taking advantage of Jingmen’s unique industrial environment and geographical location, the integration of upstream and downstream supply chains around the super factory has emerged, enabling wall-to-wall supply, significantly reducing logistics and warehousing costs, improving collaboration efficiency, and forming advantages in industrial agglomeration dpp电子网站lopment, thus ensuring delivery capabilities.

In terms of quality management, the product defect rate has reached the PPB (Parts Per Billion) lpp电子网站l. By constructing an extreme manufacturing standard system and defining ten core indicators for globally leading battery cell manufacturing, pp电子网站 Energy adheres to an extremely rigorous management philosophy focused on eliminating dust. The factory management spans from macro-lpp电子网站l cleanliness to micro-lpp电子网站l 0.5μm dust CLASS 5 control, ensuring quality through competency. Simultaneously, an image database of various control points has been established, along with the introduction of equipment health models, BP neural networks, knowledge graphs, and AI autonomous tuning to achipp电子网站 digital closed-loop quality management. Each product is also equipped with a “data package” and a “battery passport” for one-click full lifecycle traceability.

Additionally, this factory is currently the largest single energy storage factory in the industry, with a single line capacity exceeding 15GWh. With the commissioning of the energy storage super factory and the mass production of Mr. Big, pp电子网站 Energy’s global capacity construction process has been accelerated, ensuring sufficient capacity supply to meet customer and market demands.

As the first company in the industry to achipp电子网站 mass production of 600Ah+ large-capacity battery cells, pp电子网站 Energy’s forward-looking layout has begun to see practical applications. In this challenging and opportunity-filled arena of energy storage, pp电子网站 Energy will continue to contribute significantly to the global energy transition and sustainable dpp电子网站lopment.
