Summary

On page 1039 a research team reports the development of a new class of batteries that have greater capacity, a faster discharge rate, and are rechargeable. The difference is in the cathode, which is made from unusual iron-based molecules known as iron(VI), or "super-iron," compounds that absorb more electrons than the manganese dioxide currently used in most batteries.
