Mixing a form of rust and water might help to make inexpensive battery electrodes with long cycle lives a real possibility.  If they have much higher energy densities than more expensive “conventional” electrodes used in lithium batteries, so much the better. Zhaolin Liu of the A*STAR (Agency for Science, Technology and Research)  Institute of Materials Research and Engineering, Singapore; Aishui Yu of Fudan University, China, and co-workers have created an electrode material that’s not only  inexpensive, but scalable to large-scale manufacturing. Normally, lithium batteries “shuttle” lithium ions between two electrodes connected in a circuit.  According to A*STAR, “During charging, lithium ions escape from the cathode, which is made from materials such as lithium cobalt oxide. The ions migrate through a …
