On September 25, CORNEX hosted a product launch event in Yichang. Executive Vice President Bu Xiangan unveiled the new 588Ah large-capacity energy storage battery. Chairman Dai Deming, President Huang Feng, alongside hundreds of partners, financial institutions, and media representatives, witnessed this significant milestone.
This launch marks another major achievement under CORNEX's "Renewal" strategy, encompassing new equipment, production lines, processes, and technologies. It highlights CORNEX's profound dedication to R&D and its leadership in driving innovation within the energy storage sector, signifying that CORNEX's large-capacity energy storage battery technology has entered a new era.
As a steadfast innovator in the global energy storage industry, CORNEX consistently prioritizes customer value creation, continuously advancing product iterations and technological breakthroughs. From 280Ah, 306Ah, and 314Ah to 472Ah, each product generation has not only pushed technical boundaries but also precisely met evolving market and customer demands.
The newly released 588Ah energy storage battery incorporates CORNEX's cutting-edge advancements in material systems, structural design, processes, and intelligent manufacturing. A single cell breaks winding process limits to achieve 588Ah, with a mass energy density of 190 Wh/kg, a volumetric energy density of 419 Wh/L, and an energy efficiency of up to 96.5%, positioning it at the forefront of the industry.
Beyond impressive specs, the 588Ah battery excels in "High Reliability, High Safety, and Long Lifespan."
High Reliability: It utilizes the mature material system and manufacturing processes of the already mass-produced 472Ah battery, with core reliability validated through prior testing. This effective risk control ensures customers receive a "predictable and dependable" product with stable quality and rapid mass-production delivery.
High Safety: Superior safety is foundational for the large-scale application of the 588Ah battery. CORNEX has established a comprehensive safety system covering "prevention," "in-process control," and "post-event protection." Innovative structural and material designs effectively mitigate risks like internal short circuits and lithium plating. A unique directional pressure relief channel design enables millisecond-level, targeted venting of high-temperature gases.
Long Lifespan: Longevity ensures the full lifecycle value of the 588Ah battery. Leveraging three core technologies—multilevel cathode particle size control, stable anode skeleton design, and electrolyte self-healing—this battery effectively counteracts degradation, achieving over 12,000 cycles with excellent capacity retention, proving its value over time.
Launched alongside the 588Ah cell are the CORNEX 588-CTP2.0 energy storage PACK solution and the "Versatile King Kong" system platform.
The module-free CTP2.0 PACK design reduces material types and quantities by 20%. Its energy density reaches 170 Wh/kg, and volumetric energy density hits 285 Wh/L, leading the industry. A 1000°C heat-resistant barrier design effectively prevents thermal runaway propagation, extending high safety from the cell to the system level and creating a robust safeguard for power station operation. An industry-first "dual protection" process boosts production efficiency by 35%, enhancing large-scale delivery capabilities.
The "Versatile King Kong" system platform earns its name from high modularity, flexible configuration, and rapid deployment features. A standard 10-foot container offers 3.13 MWh capacity, while a 20-foot container provides 6.26 MWh. Like building blocks, it can be flexibly combined and scaled according to project specifics (e.g., power, capacity, site conditions), seamlessly adapting to diverse scenarios from generation and grid-side applications to large-scale commercial and industrial use. This design significantly enhances adaptability to varying customer needs and complex environments, shortening project delivery times and offering clients tailored integrated solutions.
Utilizing the "Versatile King Kong" system platform, a 100 MW station is projected to require 20% less land area, 27% fewer prefabricated cabins, and see operational costs reduced by over 20%.
By 2035, global annual energy storage installations are projected to reach 2 TWh. The launch of the 588Ah energy storage battery directly addresses the global market's urgent need for "higher capacity, improved cost-effectiveness, and ultimate safety." In response to challenges posed by the large-scale development of the new energy industry, CORNEX presents a robust answer with its forward-looking technology roadmap and strong manufacturing capabilities. CORNEX remains committed to injecting powerful and reliable "CORNEX Strength" into the global energy transition, empowering the creation of a cleaner, safer, and more efficient energy future.
