Read moreIn recent years, the number of patent applications for electrochemical energy storage technologies has soared. According to a new study, 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.
