Two groups of researchers in South Korea and America have added silicon and sugar as ways of gaining more energy from two different types of batteries. The 10X Battery at Last? Researchers at Pohang University of Science & Technology (POSTECH) in South Korea have developed a “layering-charged, polymer-based stable high-capacity anode material.” POSTECH professors Soojin Park (Department of Chemistry) and Youn Soo Kim (Department of Materials Science and Engineering) and Professor Jaegeon Ryu (Department of Chemical and Biomolecular Engineering) of Sogang University think their discovery could increase current electric vehicle range “at least 10-fold.” As noted in this blog many times, the idea of a 10X battery has been a matter of intense research from Yi Cui at Stanford and his research partner Jaephil Cho in South Korea, along with John Goodenough at Rice University and Jeff Dahn at Canada’s Dalhousie University – among others. Silicon and Polymeric Benders One of the bigger problems with using silicon in a battery …
