Why are batteries so expensive?

There are two main drivers. One is technological innovation. We're seeing multiple new battery products that have been launched that feature about 30% higher energy density and lower cost. The second driver is a continued downturn in battery metal prices. That includes lithium and cobalt, and nearly 60% of the cost of batteries is from metals.

Are lithium ion batteries going down?

Lithium-ion batteries are the most commonly used. Lithium-ion battery cells have also seen an impressive price reduction. Since 1991, prices have fallen by around 97%. Prices fall by an average of 19% for every doubling of capacity. Even more promising is that this rate of reduction does not yet appear to be slowing down.

Why are battery prices falling?

Despite this, battery prices have kept falling – just not by as much as they otherwise would have. The world’s huge demand for lithium has led to strong growth in supply, as miners scramble to find new sources. CATL, for instance, is spending A$2.1 billion on lithium extraction plants in Bolivia.

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.

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.

Why are battery sales growing exponentially?

Battery sales are growing exponentially up classic S-curves that characterize the growth of disruptive new technologies. For thirty years, sales have been doubling every two to three years, enjoying a 33 percent average growth rate. In the past decade, as electric cars have taken off, it has been closer to 40 percent.
