What are the patent directions of the energy storage industry

Can patents be used to map energy storage technologies?

Albeit a gush of recent work using patents in connection with energy storage for particular technologies (e.g. , , , ), patents remain under-exploited for conducting integrative mapping exercises of battery development, i.e. across types, geographies and long stretches of time (some exceptions being , , ).

How fast do batteries & electricity storage technology develop?

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. Innovation in Batteries and Electricity Storage - Analysis and key findings. A report by the International Energy Agency.

Which technologies grew in relevance to battery patenting?

We find that several battery-related technologies and applications, such as energy storage systems, battery management systems, wireless power transmission, electric vehicle charging, and uncrewed aerial vehicles (i.e., drones), grew in relevance both in absolute terms and relative to general battery patenting activity.

Why do we need patents for green innovation?

Recently, patents have been increasingly mobilized to track developments in green innovation, including in strategic emerging sectors like clean technology and renewable energy , .

Why is battery patenting a global trend?

We find that global battery patenting activity grew significantly in the 2000–2019 period. This stylized fact means that the comparative advantages of secondary approaches (rechargeable, redeployable, reusable batteries) have been continuously on the rise driven by innovation, making a direct contribution to socio-technical circularity.

Are national battery patent applications considered in IEA & EPO?

Given the IPF constraint deployed for this study and the IEA and EPO report , these solely nationally filed applications are not considered in either one. In fact, in the current study’s dataset, IPFs make up only 19.4% of all battery patent families.
