CALB recently signed a formal procurement agreement with Japan’s GRF Corporation for a 220 MWh battery energy storage system (BESS) project. The partnership brings together two industry leaders to deepen their presence in Japan’s high-end energy storage market while extending their global green-energy storage footprint.
Looking ahead, the two companies will focus on core application areas including grid-side storage in Japan, renewable-plus-storage projects, and power backup for data centers, jointly exploring the global green storage market.
Notably, in March this year, CALB also signed a 380 MWh agreement with Namcha Barwa Co., Ltd(ナムチャバルワ), a Japanese energy storage developer. That project marked the recognition of CALB’s DC-side storage products in the Japanese market.
The newly announced project will feature CALB’s “Zhijiu” (Everlast) storage battery cells, leveraging the company’s proprietary core cell technology, liquid-cooling thermal management, and intelligent BMS. The system delivers three key advantages—high safety, high stability, and high energy density—enabling efficient energy storage, intelligent dispatch, and low-carbon utilization.
In 2025, CALB reported total revenue of RMB 44.40 billion (about $6.46 billion US), up approximately 60.0% year-on-year, and net profit of RMB 2.095 billion (about $308.4 million US), a year-on-year surge of about 148.4%. The company’s profitability achieved a significant leap, underscoring its sustained high-quality growth trajectory.
Within that, revenue from energy storage systems and other related products grew from RMB 8.201 billion (about $1.20 billion US) in 2024 to RMB 14.100 billion (about $2.07 billion US) in 2025, representing a 71.9% increase. The robust growth was primarily driven by the company’s continuous expansion in the energy storage system product segment, with annual shipments rising sharply. CALB ranked fourth globally in energy storage cell shipments for the year.
