An international team of engineers and materials scientists has developed a lithium-sulfur battery capable of retaining 80% of its charge capacity after 25,000 cycles. Their paper is published in ...

significantly improved the performance of a button-sized lithium-sulfur battery. The researchers found that the battery could hold its charge over 500 cycles, a significant improvement over ...

Sulfur-based battery cathodes have so far been unable to escape degradation during operation. But scientists in Germany may have a solution that brings to bear the abundant, cheaper material's ...
