At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when the sun doesn’t shine.
Our analysis shows that the past very high storage costs are now rapidly falling. This suggests that the financial appeal of electric cars and stationary storage is set to keep increasing considerably in years ahead.
First introduced by Sony in 1990, lithium-ion batteries are already the dominant type of battery for technologies such as mobile phones, laptops and electric cars, and are expected to remain so for some time. Their strength lies in being able to store a high amount of energy in a relatively small and lightweight package, as well as being capable of charging and discharging thousands of times while retaining most of their storage capacity.
