CORNEX Showcased a 472Ah Energy Storage Cell (12,000 cycles) and a 4C Ultra-fast Charging Battery at CIBF

At the 17th China International Battery Fair (CIBF 2024), CORNEX made a significant impact on industry experts by showcasing its cutting-edge solutions for energy storage systems (ESS) and electric vehicles (EVs). Held at the World Convention and Exhibition Center in Shenzhen from May 15, the event served as a key stage for CORNEX to present innovative technologies that are transforming global energy infrastructure.

Game-Changing Energy Storage Solutions

CORNEX's 472Ah energy storage cell stole the show, marking a milestone as it enters mass production. This high-performance cell provides 1,510.4Wh per unit, offering a remarkable 50% increase in capacity compared to traditional cells. It boasts over 12,000 charge cycles, enhancing the longevity and efficiency of energy storage systems. When integrated into 20-foot battery containers, these systems reach a total capacity of 6.9MWh, cutting lifetime costs by 20%, making it a highly cost-efficient solution for large-scale and commercial storage applications.

Innovations in Electric Vehicle Battery Technology

CORNEX also revealed its 120Ah fast-charging cell, designed to support 800V architectures. With an impressive energy density of 191Wh/kg and the ability to charge at a 4C rate, this cell enables electric vehicles to achieve driving ranges between 350 and 750 km. The company also showcased specialized cells for a range of commercial electric vehicles, marine vessels, and construction machinery, demonstrating the versatility of their technology across different industries.

Next-Level Safety Solutions for Energy Systems

CORNEX's upgraded Submerge 2.0 safety platform garnered attention with its advanced features, including a 6-second fire suppression time, 27% enhanced cooling efficiency, and a 98% reduction in coolant usage. Combined with the CTP 3.0 liquid cooling system, which delivers over 80% volumetric efficiency in battery packs, these innovations address crucial thermal management issues, making them ideal for high-performance energy systems in extreme environments.

Addressing the diversified demands of the global energy transition, CORNEX has forged a strategy of "ESS+EV batteries", constructing a multi-dimensional green energy ecosystem spanning power systems, transportation, and end-user consumption.

At the exhibition, CORNEX showcased flagship products under such strategy. On the energy storage front, alongside the next-gen 472Ah cell, its "π Series" ultra-long cycle life and high-temperature-durable customized solutions attracted significant client interest. For EV applications, over a dozen high-performance EV cells cover models from Mini EVs to C+ segment, pure electric to hybrid, while 21Ah, 230Ah and 324Ah commercial cells are widely used in low-speed vehicles, construction machinery, and marine applications.

As of April 2025, CORNEX has filed nearly 5,000 patents globally, developed over 60 products in ESS and EV battery fields, and advanced technologies across lithium-ion, solid-state, sodium-ion, lithium manganese iron phosphate (LMFP), and cylindrical cell routes, with over 200 product certifications secured.

To bolster its global strategy, CORNEX has established a technical service network spanning 15 countries and regions, enabling 24/7 rapid response capabilities while securing authoritative international certifications including UL and IEC. Through technological innovation and localized service solutions, CORNEX products have successfully penetrated multiple overseas markets, with its global footprint continuously expanding.

CORNEX has formulated the "ESS+EV battery" strategy and built a multi-dimensional green energy ecosystem covering the power system, transportation and end-user consumption.

In the field of energy storage, in addition to the new generation of 472Ah battery cells, the "π series" of ultra-long cycle life and high-temperature resistant customized solutions have also been launched.

In the field of electric vehicle applications, more than ten high-performance electric vehicle battery cells cover a wide range of models from micro electric vehicles to C+ class, pure electric to hybrid vehicles, while 21Ah, 230Ah and 324Ah commercial battery cells are widely used in low-speed vehicles, construction machinery and Marine applications.

CORNEX continues to solidify its position as a global leader in energy innovation, with over 5,000 patents and 60+ commercialized products. The company is driving targeted international collaborations that further its commitment to the global energy transition:

· 2.5GWh ESS partnership with the UK-based Immersa to enhance energy storage solutions.

· Introduction of heat-resistant energy storage solutions tailored for the extreme climates of the Middle East.

· A 5GWh supply agreement in India, aimed at stabilizing the national power grid and enhancing energy reliability.

CORNEX’s technical service network now spans 15 countries and is supported by key global certifications, including UL and IEC. This extensive service infrastructure, combined with the company’s cutting-edge lithium-ion, solid-state, and sodium-ion battery research and development, allows CORNEX to push the boundaries of innovation across multiple battery technologies.

As the global push for decarbonization intensifies, CORNEX’s dual approach—focusing on both energy storage systems (ESS) and electric vehicle (EV) technologies—positions the company as a key player in grid resilience and sustainable transportation. With several innovations successfully transitioning from the lab to commercial markets, CORNEX is redefining the future of energy infrastructure with scalable and cost-efficient solutions.
