“A dramatic fall in the price of lithium-ion batteries over the past decade is transforming the economics of renewable energy as well as the affordability of electric vehicles.
Since 2010 the cost of a lithium-ion battery per kilowatt hour (kWh) has fallen almost 90%, from $1,183 in 2010 to just $156 in 2019.
