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 Universitдt Mьnchen, the largest volume of applications is submitted by developers of lithium batteries. The study offers a first differentiated analysis of which technologies will be viable in the exit from fossil-fuel energy. European and US companies are falling behind economically, as Asian companies apply for a substantially higher number of patents.
