Cornex Unveils Next-Generation 588Ah Battery for Energy Storage

YICHANG, China – September 25 – Cornex New Energy showcased its latest innovation in energy storage with the launch of its next-generation 588Ah large-capacity specialized battery at a product release event held here. The occasion was witnessed by Cornex leadership, including Chairman Dai Deming and President Huang Feng, alongside hundreds of partners, financial institutions, and media guests.

This new product marks a significant milestone under Cornex's comprehensive renewal strategy, which focuses on new equipment, production lines, processes, and technologies. It underscores the company's deep commitment to R&D and its role in leading innovation within the energy storage industry, signaling a new phase for large-capacity battery technology.

Pushing the Limits of Innovation
Positioned as a steadfast innovator in the global energy storage sector, Cornex consistently anchors its development on creating value for customers, driving continuous product evolution. From 280Ah to 472Ah, each iteration has not only advanced technical specifications but also precisely responded to market and client needs.

The new 588Ah battery incorporates Cornex's cutting-edge achievements in material science, structural design, and intelligent manufacturing. It breaks through the limits of winding technology to achieve a single-cell capacity of 588Ah, with a mass energy density of 190 Wh/kg, a volumetric energy density of 419 Wh/L, and an energy efficiency of 96.5%, placing it at the forefront of the industry.

Beyond these parameters, the battery is engineered with three core advantages: high reliability, enhanced safety, and long service life.

• High Reliability: The 588Ah battery utilizes the mature material system and manufacturing processes of the already mass-produced 472Ah battery. This transfer of proven technology mitigates risks associated with new products, ensuring predictable, dependable quality and facilitating rapid mass production and delivery.

• High Safety: Safety is a cornerstone of the 588Ah battery's design. Cornex has implemented a full-stack safety system encompassing prevention, control, and protection. Innovative structural materials reduce the risk of internal short circuits and lithium plating, while a unique directional venting channel design enables millisecond-level pressure release in extreme conditions.

• Long Life: Addressing lifecycle value, the battery employs three core technologies—multi-level particle size control for the cathode, a stable skeleton design for the anode, and a self-repairing electrolyte—to precisely combat degradation. This results in an ultra-long cycle life exceeding 12,000 cycles and excellent capacity retention.

Integrated Solutions for Diverse Applications
Accompanying the cell launch were the Cornex 588-CTP 2.0 PACK solution and the versatile "Variable King Kong" system platform.

The CTP 2.0 PACK's minimalist, modular design reduces the number and types of components by 20%, achieving a leading mass energy density of 170 Wh/kg and volumetric density of 285 Wh/L. Safety is extended to the system level with a heat-resistant barrier capable of withstanding 1000°C, effectively blocking thermal propagation. An industry-first production process boosts manufacturing efficiency by 35%, enhancing large-scale delivery capabilities.

The "Variable King Kong" platform is defined by its high modularity, flexibility, and rapid deployment. A standard 10-foot cabinet offers 3.13 MWh, while a 20-foot cabinet reaches 6.26 MWh. Like building blocks, the system can be flexibly configured and scaled to meet specific project requirements for power, capacity, and site conditions, seamlessly adapting to generation-side, grid-side, and large-scale commercial and industrial applications. This design significantly shortens project delivery times and provides clients with tailored, integrated solutions.

The application of this platform is projected to reduce the footprint of a 100-megawatt-level storage station by 20%, decrease the number of prefabricated cabins by 27%, and lower operational costs by over 20%.

With global energy storage installations projected to rise significantly by 2035, the introduction of the 588Ah battery directly addresses the market's urgent demand for higher capacity, improved cost-effectiveness, and utmost safety. Through forward-looking technology and solid manufacturing prowess, Cornex is providing a powerful and reliable answer for the global energy transition.
