Battery manufacturers are competing to produce large battery cells.

Since July, the dynamics of battery manufacturers in the field of large energy cells for energy storage have been particularly intense:

On July 30th, Rongjie Energy signed a 5GWh supply memorandum with Indian power company JSW, and will provide the latter with two types of 5MWh and 6.26MWh containerized and CKD spare parts, respectively, which are equipped with 314Ah and 588Ah batteries.

On July 27th, Pengcheng Unlimited and Jiayang Energy signed a long-term 25GWh battery supply contract, which includes a 5GWh supply scale of 587Ah large-capacity batteries. The delivery will be completed between 2027 and 2028.

On July 24th, Xinhua Wangda announced that its subsidiary Xinhua Wangda Power intends to conduct a C+ round of capital increase and share expansion. Suning Power will invest 655 million yuan, and the collaboration relationship between the two regarding 684Ah batteries has thus come to the forefront. On the same day, the semi-annual report released by Ningde Time showed that its 587Ah large batteries have achieved large-scale delivery; in addition, public information indicates that as of April this year, the cumulative shipment of its 587Ah batteries has exceeded 5GWh.

On July 15th, the Yancheng Super Factory of Envision Power was put into production. The first batch of 790Ah large batteries produced there were rolled off the production line and shipped to Germany immediately, for delivery to overseas energy storage customers.

The hot orders confirm the strong market demand. In May, Yiliu Lithium disclosed on the interactive platform that its energy storage battery business had full orders and was in a state of full production and sales. In the first quarter, its energy storage battery shipment reached 20.38GWh, a year-on-year increase of 60.82%. In June, it landed several energy storage strategic cooperation projects within three days, with a cumulative signing scale exceeding 67GWh.

At the same time, capacity expansion has also been intense. Statistical data from institutions show that among the expansion projects in the past year, there are 9 that clearly mainly produce large-capacity energy storage batteries, among which 8 projects mention 500+Ah batteries, with a total capacity of over 200GWh, involving battery manufacturers such as Yiliu Lithium Energy, Zhengli New Energy, Haidun Energy Storage, and Pengcheng Unlimited.

Overall, from the top-level design of policies to the capacity positioning of enterprises, from the large-scale deployment in the domestic market to the large-scale release of demand in Europe, America, Australia, and emerging markets, the energy storage industry is undergoing a profound transformation from "quantity" to "quality". As long-duration energy storage gradually upgrades to a "grid necessity", battery capacity is accelerating towards 500+Ah or even higher, but from the laboratory to the grid, the market is the ultimate tester.
