Contemporary Amperex Technology Co Ltd (CATL) has started large-scale commercialization of its next-generation high-capacity battery cells for energy storage systems, after shipments of its 587-ampere-hour (Ah) product reached 2 gigawatt-hours (GWh), Chinese media outlet Jiemian reported.
Shipments of the 587-Ah cell are expected to rise to about 3 GWh this year, the report said. The product was launched in June as CATL’s latest iteration following its earlier 280-Ah and 314-Ah energy storage batteries.

The company’s production base in Jining, in China’s Shandong province, supports a daily output of more than 220,000 units of the 587-Ah cell, according to the report. Average production time is under two seconds per cell, with manufacturing costs down about 42% and safety failure rates at the parts-per-billion level.
CATL said at its June launch event that the 587-Ah cell delivers an energy density of 434 watt-hours per litre, about 10% higher than its predecessor, after three years of research and testing. The company added that its cumulative global deployment of energy storage systems has exceeded 256 GWh across more than 1,000 projects worldwide.
