The high voltage electrode of a big battery designed for grid-scale storage of renewable energy is based on copper hexacyanoferrate nanoparticles. After 40,000 charge cycles, 83% of the material's original charge capacity is retained, equivalent to a century of daily charges. Stanford University researchers are now developing the low voltage anode component.
