Longer-duration storage, safety-driven procurement and Foreign Entity of Concern (FEOC) compliance in the United States are accelerating interest in alternative battery chemistries, even as lithium-ion remains dominant amid rising data center demand and tighter supply chain. Longer-duration storage, safety-driven procurement and Foreign Entity of Concern (FEOC) compliance in the United States are accelerating interest in alternative battery chemistries, even as lithium-ion remains dominant amid rising data center demand and tighter supply chain. Breakthroughs in battery technology are transforming the global energy landscape, fueling the transition to clean energy and reshaping industries from transportation to utilities. With demand for energy storage soaring, what's next for batteries—and how can businesses, policymakers, and investors. Battery storage is the fastest growing power technology today. In 2025, 108 GW of new battery storage capacity was deployed worldwide, 40% more than in 2024. Lithium‑iron phosphate (LFP) batteries now account for around 90% of deployments;. As demand for energy storage soars, traditional battery technologies face growing scrutiny for their cost, environmental impact, and limitations in energy density. From EV innovation to circular supply chains, several key trends are redefining energy storage.
