...Between 2005 and 2018, the number of battery-related patents grew faster than other types of patents, by an average of 14%, year after year....
...Lithium-ion batteries in consumer electronics have become 90% cheaper since 1995 and electric vehicles have seen a similar fall since 2010. However, stationary batteries saw a smaller fall, of two-thirds, in the last decade.
An EPO spokesperson tells us: “So far, the boom in batteries has been driven by lithium-ion [cells], which can indeed generate spill-overs for stationary applications (see for example Tesla powerwalls). However, Li-ion is not the only, and possibly not the best, technology option for stationary storage.
“In particular, redox-flow batteries are an important technology in this context. It is important to keep in mind that the requirements for energy storage for vehicles are quite different from those for stationary applications. For vehicles, high-energy density is key, while stationary applications mainly require low costs and scalability.
“In this sense, stationary battery innovation can benefit from innovation in the field of batteries for automotive because technology that becomes less attractive for electric vehicles can be deployed at a lower cost for stationary applications on the grid. Therefore, we expect that also in the future, battery innovation initially focused on mobility applications will then at a later stage be beneficial also for stationary applications.â€...
