ES "Search found 24 matches: manganese dioxide"... again:

Starts:
A chemistry team at the University of Waterloo, Canada, has achieved what may be a major breakthrough in battery technology. Led by Chemistry Professor Linda Nazar, the team discovered that the performance of a lithium-sulfur battery can be boosted dramatically by using a nanosheet of manganese dioxide. The increase has the potential to propel an electric vehicle three times further than a lithium-ion battery of the same weight.
Includes:
The study revealed that the surface of the manganese dioxide nanosheet essentially transforms the sulfur cathode of a Li-S battery into a high-performance cathode that can recharge more than 2,000 times. Cathodes and anodes are the two electrodes on a battery, separated by an electrolyte solution. Sulfur, which is an extremely abundant, relatively light, and very cheap battery material, historically hasn’t worked as a cathode material because it dissolves into the electrolyte solution as the battery discharges.
