On April 1, 2026, CORNEX showcased its full scenario energy storage solution at the ESIE2026 Energy Storage Exhibition, taking the lead in showcasing a 6.25MWh energy storage system solution based on the integration of 588Ah batteries and CTP3.0 non modular technology, which attracted high attention from the industry. As the industry's first solution to deeply integrate 588Ah large battery cells with CTP3.0 modular technology, it has demonstrated unique value in system integration efficiency, thermal management safety, and large-scale applications.

200GWh production capacity 'heavily invested' 588Ah: ultimate balance achieves leading performance

Against the backdrop of the industry's widespread focus on battery capacity improvement, CORNEX's new generation 588Ah energy storage battery not only maintains product performance leadership, but also further strengthens product dimensions such as "long cycle, high safety, and high reliability", reflecting its profound understanding of the essence of energy storage product applications.

In terms of performance parameters, the 588Ah battery achieved a leading performance with a mass energy density of 190Wh/kg, a volume energy density of 419Wh/L, and an energy efficiency of 96.5% in the lithium iron phosphate system. By applying three core technologies of positive electrode multi-stage particle size control, negative electrode stable skeleton design, and electrolyte self-healing technology, the 588Ah battery has achieved a cycle life of over 12000 cycles and high capacity retention rate.

In terms of safety, CORNEX has targeted the actual pain points of large-scale energy storage application scenarios during the product design phase, from inherent battery safety to system level protection. Through the dual efforts of structural innovation and material innovation, CORNEX has built a full stack safety system for the 588Ah battery, laying a solid foundation for the long-term stable operation of the energy storage system.

In terms of reliability, the 588Ah battery has shifted the mature material system and manufacturing process of Chu Energy's mass-produced batteries, and its core reliability has been verified in batches. At the same time, relying on a mature supply chain and large-scale production system, it can bring customers "predictable and reliable" stable quality.

It is worth noting that in the context of the increasingly prominent demand for large-scale high-quality production capacity in the industry, CORNEX has laid out a production capacity plan of over 200GWh for 588Ah batteries, which will provide a solid guarantee for the large-scale production of 588Ah batteries.

CTP3.0 Efficiency Breaks 60JPH, Empowering 6.25MWh System for Large Scale Security Applications

The 588Ah battery has laid a solid foundation in terms of performance, and the CTP3.0 module free integration technology is a key link in safely and efficiently applying it to the 6.25MWh system. CORNEX showcased its innovative application in the field of efficient integration of energy storage systems through the combination scheme of "588Ah battery+CTP3.0 platform+CORNEX M6 energy storage system".

Based on the 588Ah battery and CTP3.0 platform, CORNEX has further launched a new generation of CORNEX M6 energy storage system solution, constructing a set of progressive and collaborative optimization technology matrices. The system adopts a standard 20 foot prefabricated cabin design, with a rated power of 6250kWh. It is equipped with a top out wind and heat management system and an active balancing BMS, achieving comprehensive improvement in safety and stability at the system level.

Among them, the industry-leading CTP3.0 module free integration technology is an important breakthrough in the traditional energy storage PACK structure. According to on-site technicians, this integrated technology breaks the constraints of module homogenization. By simplifying redundant structures, the energy density of a single package can reach up to 280Wh/L, and the rated power can reach 195.68kWh, achieving the ultimate integration of batteries and battery packs in a limited space

More importantly, the CTP3.0 platform adopts the "suction protection dual method" process, integrating 104 588Ah batteries into the box, greatly optimizing the production process, not only improving intrinsic safety, but also pushing the production efficiency (60JPH) to four times the industry average efficiency (15JPH). This leapfrog improvement means that CORNEX will have significant cost advantages and delivery efficiency in large-scale manufacturing.

From the performance breakthrough of 588Ah battery, to the efficiency innovation of CTP3.0 module free technology, and to the efficient integration and implementation of 6.25MWh energy storage system, CORNEX has built a full chain innovation matrix from battery to system. The core logic of this matrix is clear and explicit: based on high-capacity batteries and powered by a modular structure, ultimately achieving a balance between safety and efficiency at the system level. At the critical juncture of continuously deepening the application value of products in the industry, CORNEX is driving its own "acceleration" through full chain innovation.Editor/Yang Meiling
