Researchers at Stanford University have used nanoparticles of copper hexacyanoferrate to create electrodes that could lead to large batteries for storing excess power from the electrical grid for future use. These might be best used in wind and solar farms, the researchers stated in a paper published recently. The nanoparticles allow for faster charging and discharging of electricity and could allow the creation of low-cost large batteries that have a relatively long life.
