Average lithium-ion battery pack costs fell 8% to $108/kWh in 2025, a 93% drop since 2010. China leads at $84/kWh with LFP, while stationary storage packs hit benchmark lows of $50/kWh amid innovation and hedging strategies. . In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are developed from an analysis of recent publications that include utility-scale storage costs. Global lithium-ion battery prices continued their downward trajectory in. . DOE's Energy Storage Grand Challenge supports detailed cost and performance analysis for a variety of energy storage technologies to accelerate their development and deployment The U. Department of Energy's (DOE) Energy Storage Grand Challenge is a comprehensive program that seeks to accelerate. . In 2026, you're looking at an average cost of about $152 per kilowatt-hour (kWh) for lithium-ion battery packs, which represents a 7% increase since 2021. Energy storage systems (ESS) for four-hour durations exceed $300/kWh, marking the first price hike since 2017, largely driven by escalating raw. . In 2023, lithium-ion batteries averaged $150-$200 per kWh globally – a 90% drop since 2010. But what drives these numbers, and where will they stabilize? Three factors dominate battery storage costs: Germany's residential battery installations hit 430,000 units in 2023 despite per-kWh costs. .
