588Ah! CORNEX New Generation Energy Storage Battery Released!

2025-09-30 | Eric

On September 25th, CORNEX held a product launch event in Yichang, where CORNEX Executive Vice President Bu Xiangan unveiled the new 588Ah large-capacity energy storage battery. CORNEX Chairman Dai Deming, President Huang Feng, along with hundreds of partners, financial institutions, and media guests, witnessed this important moment.

This energy storage product release marks another milestone under CORNEX's "renewal" strategy, which includes new equipment, new production lines, new processes, and new technologies. It reflects CORNEX's deep commitment to technological research and development and its leadership in driving innovation within the energy storage industry, marking the entry of CORNEX's large-capacity energy storage battery technology into a new phase.

Ultimate Innovation Redefines Energy Limits

As a steadfast innovator in the global energy storage industry, CORNEX has always placed value creation for customers at the core of its development, continuously driving product iterations and technological innovations. From 280Ah, 306Ah, and 314Ah to 472Ah, each product iteration has not only refreshed technical parameters but also precisely responded to market and customer needs.

The newly released 588Ah energy storage battery integrates CORNEX's cutting-edge technological achievements in material systems, structural processes, and intelligent manufacturing, accumulated over years. A single battery breaks the limits of the winding process to reach 588Ah, with a mass energy density of 190Wh/kg, a volumetric energy density of 419Wh/L, and an energy efficiency of up to 96.5%, reaching industry-leading levels.

On top of refreshing technical parameters, the 588Ah battery also offers significant advantages of "high reliability, high safety, and long lifespan".

• High Reliability: The 588Ah battery adopts the mature material system and manufacturing process of the already mass-produced 472Ah battery, with core reliability validated through preliminary testing. This effectively controls risks for the new product, ensuring customers receive a "predictable and dependable" stable quality and quick mass production delivery.
• High Safety: High safety is the cornerstone for the large-scale application of the 588Ah battery. CORNEX has built a comprehensive safety system from "prevention" to "in-process control" and "post-protection". Through innovative structural material designs, the risks of internal short circuits and lithium precipitation are effectively reduced; a unique directional pressure relief channel design achieves millisecond-level directional pressure release for high-temperature airflow.
• Long Lifespan: Long lifespan ensures the full lifecycle benefits of the 588Ah battery. With three core technologies—multilevel particle size control for the cathode, stable skeleton design for the anode, and electrolyte self-healing technology—this battery effectively addresses the issue of battery degradation, achieving over 12,000 cycles with excellent capacity retention, proving its value over time.

Smart Integration Empowering Diverse Scenarios

Also launched alongside the 588Ah battery is the CORNEX 588-CTP2.0 energy storage PACK solution and the "Versatile King Kong" system platform.

Thanks to its simple module-free design, the CTP2.0 energy storage PACK solution reduces the types and quantities of materials by 20%. The energy density of individual PACK units reaches 170Wh/kg, and volumetric energy density reaches 285Wh/L, leading the industry. By adopting a 1000℃ heat-resistant isolation layer design, it effectively prevents thermal spread, extending high safety from the battery level to the system level, creating a strong barrier for power station operations. The industry's first "dual protection" process boosts production efficiency by 35%, enhancing large-scale delivery capacity.

The "Versatile King Kong" system platform is named for its highly modular, flexible configuration, and fast deployment features. The standard 10-foot container has a capacity of 3.13MWh, and the standard 20-foot container has a capacity of 6.26MWh. It can be flexibly combined and expanded according to specific project requirements (such as power, capacity, and site conditions) like building blocks, perfectly adapting to diverse application scenarios from the power generation side, grid side, to large-scale industrial and commercial settings. This design greatly enhances the product's adaptability to different customer needs and complex application environments, reducing project delivery times and providing clients with a tailored integrated solution.

By applying the "Versatile King Kong" system platform, the land area required for a 100MW station is expected to decrease by 20%, the number of prefabricated cabins will decrease by 27%, and operating costs will be reduced by more than 20%.

By 2035, global energy storage installations are expected to increase to 2TWh/year. The launch of the 588Ah energy storage battery aims to precisely address the global energy storage market's urgent demand for "higher capacity, better cost, and ultimate safety". In response to the challenges posed by the large-scale development of the new energy industry, CORNEX presents a solid answer with its forward-looking technological layout and robust manufacturing capabilities. CORNEX will continue to inject powerful and reliable "CORNEX strength" into the global energy transition, empowering the creation of a cleaner, safer, and more efficient energy future.
