Envision AESC recently announced a strategic cooperation agreement with Prevalon Energy, a utility-scale battery energy storage system (BESS) integrator. Over the next three years, Envision AESC will supply more than 10 GWh of high-quality energy storage cells and modules to Prevalon, supporting the deployment of the latter’s utility-scale projects worldwide. The partnership targets critical applications including renewable integration, grid reliability enhancement, and power infrastructure for AI data centres (AIDC).
Prevalon Energy is a BESS joint venture between Mitsubishi Power Americas and EES. Focused on developing and deploying utility-scale storage solutions, the company has already installed or contracted over 6 GWh of storage projects globally and holds 1.3 GW of firm supply agreements tied to AI data centre power infrastructure.
As renewable energy capacity expands rapidly, system peak-load regulation and grid-stability pressures are intensifying, making the development of new energy storage a fundamental necessity for building modern power systems.
Industry data shows that global battery storage shipments reached 651.5 GWh in 2025, surging 76.2% year-over-year, a clear sign of accelerating market momentum. Chinese manufacturers dominated the sector, accounting for 614.7 GWh, or 94.4% of the global total. For most battery makers, energy storage has emerged as a second growth engine after electric vehicle (EV) batteries. In some companies, storage shipments have already begun to outpace their EV battery volumes.
Contemporary Amperex Technology Co. (CATL), for example, reported that storage batteries accounted for approximately 25% of its first-quarter 2026 sales. Over the past three years, the company has consistently reported a storage share of around 20% of total battery shipments.
Notably, it is not only Chinese players that are pivoting. South Korean battery manufacturers, including LG Energy Solution, SK On, and Samsung SDI, have also begun adjusting production capacity, gradually converting some EV battery lines to storage battery production.
In September 2025, SK On announced it would convert part of its NCM (nickel-cobalt-manganese) EV battery production lines at its Georgia plant in the US to LFP (lithium-iron-phosphate) storage battery lines. Separately, Samsung SDI revealed plans to retool its Indiana plant—operated through its joint venture with Stellantis—shifting from NCA (nickel-cobalt-aluminum) EV batteries to LFP batteries dedicated to energy storage systems (ESS).
Industry analysts believe that energy storage is currently a faster-growing segment than EV batteries, with global storage shipments expected to grow by roughly 70% in 2026, nearly double the growth rate of the EV battery market. For lithium-battery enterprises, the rapid expansion of the storage market represents a pivotal opportunity to break through their business “ceilings.”
As global EV sales growth continues to moderate, more lithium-battery companies are expected to shift strategic focus toward energy storage, which is poised to become a new lever for enhancing their competitive edge in the broader battery industry.
