Complete Portfolio from Utility-Scale to C&I and Emerging Applications

CALB used EES Europe and Intersolar Europe in Munich to launch its full ZHIJIU series of energy storage solutions. The lineup covers utility-scale plants, commercial and industrial parks, and new applications. It is built around long-cycle cells and standardized system platforms. With an integrated delivery model covering cells, systems, and after-sales service, CALB says it can lower the levelised cost of storage across the asset lifetime, giving developers a clearer path to safe, efficient, and cost-competitive green power.

Utility-Scale Liquid-Cooled Systems for European Grids

The utility-scale lineup uses a full-stack liquid-cooled integrated architecture designed to meet Europe's grid-code and environmental requirements. A 25-year design life and high energy density make these systems reliable foundation assets for front-of-meter storage.

661Ah Ultra-Large Laminated Long-Cycle Cell

The flagship product uses the industry's first third-generation lamination process combined with advanced lithium-compensation technology. Rated for 15,000 charge-discharge cycles, it shows zero capacity degradation over the first three years and a calendar life of 25 years.

588Ah Large-Capacity Wound Long-Cycle Cell

This wound cell uses mature manufacturing processes and long-cycle chemistry, designed as a proven workhorse for full-duration storage. It offers differentiated value for investors looking for reliable, bankable assets.

6.25MWh Second-Generation ZHIJIU Liquid-Cooled Container

The new container balances energy density and transport logistics within standard 20-foot dimensions. It delivers about 25% higher unit capacity than its predecessor while cutting system components by roughly 40%, simplifying installation and maintenance.

20ft 6.9MWh and 10ft "10MWh+" Modular Systems

The 20ft version offers higher density and lower capital expenditure. The 10ft decoupled architecture simplifies shipping and on-site assembly, speeding up construction and grid connection. This suits future long-duration storage projects where modularity and speed matter.

C&I Cabinets with Multi-Layer Fire Protection

For commercial and industrial parks, CALB showed two liquid-cooled outdoor cabinets at 261kWh and 418kWh. They come with ventilation and explosion-relief structures for multi-layer active fire protection. They support single or multi-parallel setups with full European and American certifications. Paired with long-cycle cells and full-range liquid cooling, the cabinets deliver better safety and life-cycle economics, shortening payback periods for commercial users.

Beyond Bulk Storage

CALB's long-cycle cell family, including its globally mass-produced 314Ah Gen2.0 cells, supports various emerging storage use cases from behind-the-meter peak shaving to hybrid renewable-plus-storage projects. CALB sees these cells as the core building block for next-generation energy systems needing both endurance and flexibility.

Positioning for the Global Energy Transition

With a comprehensive ecosystem spanning utility-scale, C&I, and diversified scenarios, CALB is positioning itself as a professional battery-technology partner for the global energy transition. The company says its combination of leading cell innovation, standardized system design, and full-scenario adaptability will help accelerate decarbonisation while keeping projects economically sustainable.
