Study highlights rise in battery tech patents
Patenting activity in batteries and other electricity storage technologies grew at an average annual rate of 14 per cent between 2005 and 2018, a joint study has revealed.
The report published by the European Patent Office (EPO) and International Energy Agency (IEA) shows that lithium-ion (Li-ion) technology, dominant in portable electronics and electric vehicles, has fuelled most of the battery innovation since 2005.

In 2011, electric vehicles overtook consumer electronics as the biggest growth driver for Li-ion battery-related inventions and industry’s push to mass produce battery electric vehicles (BEVs) saw patent-filing activity for battery-related inventions rise to over 7,000 in 2018.
The report - ‘Innovation in batteries and electricity storage’ - shows that inventions in batteries accounted for 90 per cent of electricity storage patents filed at the EPO between 2000 and 2018. A rapid acceleration in patent-filing activity related to the manufacture of battery cells and other cell-related engineering was also noted in the three years to 2018.
