On July 26, 2026, CATL announced during an investor event that its 587Ah large-format energy storage cells have achieved scalable delivery. The company's combined sales of power and energy storage batteries grew approximately 60% year-on-year in the first half of 2026, with energy storage accounting for about a quarter of total sales volume.
According to the investor relations record released by CATL, the sales structure shows that domestic energy storage sales slightly outpaced international markets, with energy storage systems accounting for nearly 70% of total energy storage revenue. This indicates strong global demand for utility-scale and commercial energy storage solutions.
CATL noted that the energy storage market will maintain rapid growth through this year and next. The company's capacity utilization was near saturation in H1 2026, reflecting robust order books. In response, CATL is actively building inventory and expanding production capacity to meet accelerating customer demand, particularly for its next-generation 587Ah cells.
This means B2B buyers in the energy storage sector should anticipate potential supply chain tightness in the short term but can benefit from CATL's increased production capacity and inventory buildup, which may shorten lead times for large-scale battery procurement.
CATL also expressed strong optimism about the Artificial Intelligence Data Center (AIDC) business, offering comprehensive energy innovation solutions that combine high-density storage with intelligent power management systems.
CATL's scalable delivery of 587Ah cells confirms the rapid industrialization of ultra-large-format batteries. For B2B clients in the drone and high-performance battery sector, this trend emphasizes the need for rapid, flexible sourcing of specialized cells.
