A paper-like battery electrode developed by a Kansas State University engineer may improve tools for space exploration or unmanned aerial vehicles. Gurpreet Singh, associate professor of mechanical and nuclear engineering, and his research team have created the battery electrode using silicon oxycarbide-glass and graphene. The research recently appeared in a Nature Communications article.1
The battery electrode has all the right characteristics. It is more than 10% lighter than other battery electrodes. It has close to 100% cycling efficiency for more than 1,000 charge discharge cycles. It is made of low-cost materials that are byproducts of the silicone industry. And it functions at temperatures as low as -15°C, which gives it numerous aerial and space applications.
