On November 13, CALB hosted its 2025 Global Partners Conference under the theme "Building an AI Ecosystem, Creating an Energy Civilization," debuting the "Zhi Jiu Series" of energy storage innovations.
The series includes 588Ah and 684Ah energy storage cells, incorporating thermal-electrical separation and dual insulation for safety, along with full-lifecycle lithium replenishment to achieve zero degradation over three years, over 15,000 cycles, and an energy density of 450Wh/L.
The "Zhi Jiu Series" energy storage systems comprise a 20-foot 6.25MWh standard unit and a long-duration platform, with variants including 10-foot 3.45MWh, 20-foot 6.9MWh, and 30-foot 12.5MWh capacities to accommodate diverse deployment scenarios.
These systems utilize a highly integrated design, cutting components by 30% versus conventional products, reducing failure rates by 20%, and lowering the levelized cost of storage by 5.8% compared to prior generations. Enhanced efficiency delivers superior returns, while a 20-year lifespan aligns with photovoltaic systems to minimize replacement expenses.
Currently, the 6.25MWh standard system has obtained GB, IEC, and UL certifications and is in mass production and delivery phases.
