Researchers in China have developed a method to convert dragon fruit peels into a carbon film for use in lithium-sulfur batteries. This material acts as a functional interlayer that helps reduce the shuttle effect, which typically degrades battery performance over time. While not yet ready for mass production, this approach demonstrates how agricultural waste can provide low-cost carbon materials to improve energy density. Such advancements are critical for developing lighter batteries for electric vehicles, drones, and aviation.
