Old chemistry gives jolt to modern batteries
Manganese dioxide stops lithium-sulfur strategy from dissolving
SAN JOSE, Calif. — Some very old chemistry may provide a new trick for making better batteries.
Scientists have developed a strategy that makes sulfur-based batteries much more efficient by exploiting chemical reactions discovered in the 1800s. The research, described February 14 at the annual meeting of the American Association for the Advancement of Science, brings scientists closer to developing cheap, long-lasting batteries to power cars and computers or store energy for the electricity grid.
