Lithium batteries come out on top in the search for electrochemical energy storage technologies
Asian inventions dominate energy storage systems
In recent years, the number of patent applications for electrochemical energy storage technologies has soared. According to a study by the Technische Universität München (TUM), the largest volume of applications by far is submitted by developers of lithium batteries. The study offers a first differentiated analysis of which energy storage technologies will be viable in the exit from fossil-fuel energy. In this area, European and US companies are falling behind economically, as Asian companies apply for a substantially higher number of patents.
