New materials could power clean energy without rare metals

May 29, 2026

The push for cleaner energy often hits a roadblock: the metals that make it possible are rare and expensive. Platinum, iridium, and ruthenium do their jobs well in hydrogen reactions, oxygen work, and battery chemistry, but they cost too much and don't last long enough for mass use. A different path

Boosting Battery Power: A New Way to Make Lithium-Sulfur Batteries Better

November 29, 2025

Lithium-sulfur batteries are a big deal. They can store a lot of energy, but they have a problem. The stuff inside them, called lithium polysulfides, moves around too much. This makes the batteries wear out faster. Scientists are trying to fix this by making better catalysts. These are like helpers
