2026-05-16 | Eric

On May 13, the 18th China International Battery Technology Conference & Exhibition (CIBF 2026) grandly opened in Shenzhen. As a top-tier global event in the battery industry, CIBF 2026 gathered cutting-edge technologies and innovative achievements from across the industry chain. CORNEX New Energy, focusing on the core requirements of global new power systems for long-duration energy storage and grid stability, launched the 588Ah large-capacity energy storage dedicated battery + CTP3.0 + M6 energy storage system full-scenario solution. Through technological breakthroughs and system innovation, it provides the optimal full-lifecycle value choice for large-scale energy storage.

Currently, as global energy transition accelerates and large-scale integration of renewable energy sources such as wind and solar increases, their intermittency and volatility pose significant challenges to stable grid operation. Long lifespan, high efficiency, high safety, and low cost have become the core directions of energy storage technology development. CORNEX abandons traditional parameter competition thinking and deeply focuses on optimizing Levelized Cost of Storage (LCOS) across the full lifecycle. Through innovation in materials, processes, and system integration, it builds core competitiveness in energy storage. At the exhibition, the 588Ah battery and M6 energy storage system immediately attracted industry attention with their leading performance and innovative design.

The 588Ah battery is CORNEX’s benchmark product in the energy storage field. Through extreme breakthroughs in winding technology and deep optimization of the material system, it achieves a comprehensive performance leap. It has a gravimetric energy density of 190Wh/kg and a volumetric energy density of 419Wh/L, maximizing capacity within limited space. With a high energy efficiency of 96.5% and a stable cycle life of 12,000 cycles, it sets an industry benchmark, far exceeding traditional energy storage batteries. Relying on CORNEX’s intelligent manufacturing capacity planning of over 200GWh, the 588Ah battery is ready for large-scale, high-consistency mass production, providing solid support for long-term stable operation of large-scale energy storage stations and protecting asset value.

At the system integration level, CORNEX CTP3.0’s module-free integration technology breaks the constraints of traditional module architecture, significantly streamlining redundant structures and achieving extreme integration of battery cells and packs. The single pack volume density reaches 280Wh/L with a rated energy of 195.68kWh. Innovative “dual protection” and “four-step block formation” processes integrate 104 pieces of 588Ah batteries into a single pack, reducing production steps by 35% and increasing production line throughput (JPH) to over 60, achieving leading production efficiency and integration quality.

Building on these core technological breakthroughs, CORNEX has developed the M6 standardized energy storage system, adopting a 20-foot prefabricated container design. The system’s rated energy reaches 6,250kWh, suitable for various scenarios including large-scale energy storage stations, grid-side peak regulation, and industrial and commercial microgrids. The system comes standard with a top-exhaust thermal management system, ensuring precise temperature control and eliminating thermal risks. Equipped with the latest generation of active balancing BMS and AI intelligent operation & maintenance algorithms, it upgrades safety from “passive protection” to “active early warning,” monitoring battery status in real-time and predicting failure risks, significantly reducing O&M costs.

From battery R&D to system integration, from performance optimization to full lifecycle cost management, the CORNEX M6 energy storage system sets a new benchmark for large-scale energy storage systems with its “large battery × high integration” standard.

Looking forward, CORNEX will continue to focus on energy storage technology innovation, leveraging strong production capacity and technological reserves to provide safer, more efficient, and more economical energy storage solutions for global new power system construction. This will facilitate efficient renewable energy utilization, ensure grid stability, and promote the green energy transition to new heights.
