‘Hybrid’ cathodes could provide more power for a given weight and volume. Researchers around the globe have been on a quest for batteries that pack a punch but are smaller and lighter than today’s versions, potentially enabling electric cars to travel further or portable electronics to run for longer without recharging. Now, researchers at MIT and in China say they’ve made a major advance in this area, with a new version of a key component for lithium batteries, the cathode.
The team describes their concept as a “hybrid” cathode, because it combines aspects of two different approaches that have b...
