Innovation in Batteries and Electricity Storage

A global analysis based on patent data

This joint study by the International Energy Agency and European Patent Office underlines the key role that battery innovation is playing in the transition to clean energy technologies. It provides global data and analysis based on the international patent families filed in the field of electricity storage since 2000 (over 65 000 in total). It reveals that between 2005 and 2018, patenting activity in batteries and other electricity storage technologies grew at an average annual rate of 14% worldwide, four times faster than the average of all technology fields.
