Why has the price of energy storage lithium batteries fallen recently

MIT researchers find the biggest factor in the dramatic cost decline for lithium-ion batteries in recent decades was research and development, particularly in chemistry and materials science.

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. To reduce emissions, the world needs to rapidly transition towards a low-carbon energy system.

MIT researchers find the biggest factor in the dramatic cost decline for lithium-ion batteries in recent decades was research and development, particularly in chemistry and materials science. This outweighed gains achieved through economies of scale, which was the second-largest category of reductions.

Since last summer, lithium battery cell pricing has plummeted by approximately 50%, according to Contemporary Amperex Technology Co. Limited (CATL), the world’s largest battery manufacturer. In early summer 2023, publicly available prices ranged from 0.8 to 0.9 RMB/Wh ($0.11 to $0.13 USD/Wh), or about $110 to 130/kWh.

Lithium-ion batteries, those marvels of lightweight power that have made possible today’s age of handheld electronics and electric vehicles, have plunged in cost since their introduction three decades ago at a rate similar to the drop in solar panel prices, as documented by a study published last March.

6 FAQs about [Why has the price of energy storage lithium batteries fallen recently ]

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 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.

How much does a lithium ion battery cost?

Lithium-ion batteries are used in everything, ranging from your mobile phone and laptop to electric vehicles and grid storage.3 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.

Why are lithium-ion batteries falling?

Behind clean energy today is a sharp, continuing drop in photovoltaic solar-cell prices. And behind the scenes, the prices of lithium-ion batteries are plummeting just as quickly.

How much does a lithium battery cost in 2023?

Why do companies buy lithium-ion batteries?

Instead, manufacturers buy lithium-ion batteries and build them into electronics and cars. Large companies like Apple or Tesla buy batteries by the millions, or manufacture them themselves, for prices that are negotiated or internally accounted for but never publicly disclosed.
