2025-09-15 | Calvin

From September 9 to 11, the largest renewable energy exhibition in North America, RE+ 25, was held in Las Vegas, USA. CALB showcased a range of innovative products, including the mass-produced second-generation 314Ah long-life cell and the 6MWh+ liquid-cooled energy storage container system. For the first time, the company also unveiled two major series of ultra-high-capacity long-life cells — 500Ah+ and 600Ah+. By advancing along both winding and large-format stacking technology routes, CALB provides cutting-edge solutions for diverse energy storage scenarios, redefining benchmarks for industry economics and reliability.

Three Key Technological Highlights

Ⅰ. 600Ah+ Stacked Cell: Industry First, Performance Breakthrough

• Revolutionary process and outstanding performance: Featuring third-generation stacking technology, achieving 15,000 cycles, 430Wh/L energy density, and 96.5% system efficiency;
• Enables 20-foot containerized energy storage systems to reach an energy density of over 6.9MWh, setting a new industry benchmark.

Ⅱ. 500Ah+ Wound Cell: Mature Technology, Broad Compatibility

• Cycle life up to 12,000 cycles, adaptable to a wide range of applications, suitable for various temperature, rate, and load conditions;
• Stable cathode material system ensures high efficiency throughout a 20-year lifecycle.

Ⅲ. Second-Generation 314Ah Long-Life Cell: Built to Last, the “Super Cell”

• Ultra-long cycle life: Up to 15,000 cycles, delivering more than 20% longer service life compared to mainstream products;
• Significantly reduces levelized cost of storage (LCOS) by as much as 20% over its lifetime.
