6 Frequently Asked Questions about “Battery system costs over the years”

How has the cost of battery storage changed over the past decade?

The cost of battery storage systems has been declining significantly over the past decade. By the beginning of 2023 the price of lithium-ion batteries, which are widely used in energy storage, had fallen by about 89% since 2010.

How has battery quality changed over the past 30 years?

As volumes increased, battery costs plummeted and energy density — a key metric of a battery's quality — rose steadily. Over the past 30 years, battery costs have fallen by a dramatic 99 percent; meanwhile, the density of top-tier cells has risen fivefold.

Are lithium-ion battery prices falling?

The price of lithium-ion battery cells declined by 97% in the last three decades. A battery with a capacity of one kilowatt-hour that cost $7500 in 1991 was just $181 in 2018. That's 41 times less. What's promising is that prices are still falling steeply: the cost halved between 2014 and 2018. A halving in only four years.

Are battery storage costs based on long-term planning models?

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.

Why are battery costs falling?

Over the past 30 years, battery costs have fallen by a dramatic 99 percent; meanwhile, the density of top-tier cells has risen fivefold. As is the case for many modular technologies, the more batteries we deploy, the cheaper they get, which in turn fuels more deployment. For every doubling of deployment, battery costs have fallen by 19 percent.

Are battery technologies reducing energy costs?

The improvements we've seen in battery technologies are not limited to lower costs. As Ziegler and Trancik show, the energy density of cells has also been increasing. Energy density measures the amount of electrical energy you can store in a liter (or unit) of battery. In 1991 you could only get 200 watt-hours (Wh) of capacity per liter of battery.
