CALB Launches “ZhiJiu Series” Featuring Groundbreaking 588AH and 684A Cells, Forging Alliances to Accelerate Global Energy Storage Expansion
BEIJING – November 13, 2024 – CALB (China Aviation Lithium Battery), a leading global innovator in lithium battery technology, made a significant stride in the energy storage sector at its “Co-building AI Ecosystem, Co-creating Energy Civilization” 2025 Global Partners Conference. The event was marked by the grand unveiling of the ZhiJiu (To-Longevity) Series, a new lineup of energy storage products headlined by two next-generation storage cells: the CALB 588AH and the CALB 684A.
These new cells are engineered to set a new benchmark for safety, longevity, and efficiency in large-scale energy storage applications.
Breakthrough Performance of CALB 588AH and CALB 684A Cells
The CALB 588AH and the higher-capacity CALB 684A cells incorporate cutting-edge technologies designed to address key industry challenges:
-
Uncompromising Safety: Utilizing a proprietary热电分离 (Thermo-Electric Separation) design and dual insulation technology, the cells effectively isolate thermal runaway pathways, ensuring enhanced operational safety.
-
Industry-Leading Longevity: With full-lifecycle lithium replenishment technology, the cells demonstrate zero capacity degradation for the first three years. They are rated for an exceptional 15,000+ cycles, drastically reducing the levelized cost of storage (LCOS) over the system’s lifetime.
-
High Energy Density: Achieving an impressive energy density of 450 Wh/L, the cells enable more compact and powerful energy storage solutions, optimizing space utilization.
Complete Storage System Solutions
Leveraging the CALB 588AH and CALB 684A cells, CALB also introduced its comprehensive ZhiJiu Series Energy Storage Systems. This portfolio includes:
