CATL has recently adjusted the prices of its energy storage cells on its official online marketplace in China and published the pricing of its 587Ah energy storage cell for the first time. Compared with the previous model of mainly supplying large customers through GWh-scale orders, CATL is now using its online marketplace to provide standardized procurement channels for a broader range of small and medium-sized energy storage integrators.
According to CATL's online marketplace, 280Ah, 314Ah and 587Ah energy storage cells are currently available. Among them, the 587Ah cell is listed at a minimum price of RMB 0.415/Wh, becoming one of CATL's publicly available large-capacity energy storage cell products.
Meanwhile, the prices of 280Ah and 314Ah cells have increased slightly compared with early September. These prices are valid during CATL's online marketplace promotion period (September 3–September 30, China time). Whether prices will increase further after the promotion period has not yet been officially disclosed by CATL.
Note: The pricing information is based on changes observed on CATL's online marketplace and compiled through industry media comparisons.
However, the lowest prices displayed on the marketplace homepage do not necessarily represent the final prices for all procurement scenarios. According to the procurement page, actual prices vary when purchasing larger quantities:
For the industry, the first public pricing of the 587Ah cell is not simply the launch of another product. It reflects the continued shift of energy storage cell specifications toward larger capacities. Over the past few years, 280Ah and 314Ah cells have remained mainstream choices in the energy storage market. As large-scale storage projects place greater emphasis on system integration efficiency, space utilization and cost control, cells above 500Ah are becoming a new area of competition. With nearly twice the capacity of a 314Ah cell, the 587Ah cell can help reduce the number of battery clusters and simplify system integration.
At the same time, CATL's online marketplace is changing the traditional energy storage cell sales model. Previously, leading cell manufacturers mainly relied on long-term agreements and large-scale customer orders, while small and medium-sized storage integrators often purchased through distributors with limited price transparency. By making standardized product prices publicly available, CATL's marketplace provides the industry with a more direct pricing reference.
This shift is also closely connected with the growth of behind-the-meter and commercial & industrial energy storage markets. According to SNE Research data, user-side energy storage shipments reached 47.7 GWh in the first half of 2026, representing a year-on-year increase of 128%. Commercial and industrial energy storage shipments reached 39.6 GWh, growing 59% year-on-year. As more small and medium-sized storage projects enter the market, demand for standardized and small-batch cell procurement is increasing.
For CATL, the online marketplace represents not only a change in sales channels but also an approach to expanding its reach across more energy storage applications. From large-scale grid storage projects to commercial & industrial and distributed energy storage applications, the energy storage market is developing toward a more diversified customer structure.
