The CATL 587 Ah cell has now entered full-scale commercial deployment, surpassing 2GWh in shipments, with total deliveries forecast to reach 3GWh within the year.
Manufactured at CATL’s high-throughput Jining base, the cell achieves cycle times under two seconds, daily output of more than 220,000 units, 42% lower production costs, and PPB-level safety. This marks one of the fastest transitions from pilot verification to GWh-scale commercialisation seen in the battery industry.
The milestone reflects CATL’s emphasis on long-term reliability and real-world validation – key differentiators in a sector often challenged by overstated claims and inconsistent quality. Proven system performance includes:
- 15 years of stable operation at the Zhangbei wind–solar–storage project, with no cell replacement, more than 80% residual capacity, and black-start capability.
- 20+ year expected lifespan at the Jinjiang LFP project, supported by 12,000+ cycle technology.
- Well-established warranty record, with a 3.8% provision and only 0.2% actual claims in 2024.
Beyond the CATL 587 Ah cell, the company continues to advance system-level solutions such as the 9MWh TENER Stack and the Naxtra Battery, designed for extreme temperatures ranging from -40°C to +70°C.
CATL is also strengthening partnerships across next-generation technologies and scale deployments. This includes a strategic sodium-ion collaboration with Ronbay Technology, securing over 60% of annual sodium-ion cathode demand, and a ≥200 GWh long-term supply agreement with Hyperstrong in the lithium battery sector. Globally, CATL has expanded across 2,000+ projects, deploying 256 GWh and contributing to more than 40 international standards.
