In this study, scientists looked at using bio-waste carbon from jamun seeds to improve lithium-sulfur batteries. The bio-carbon had a lot of tiny holes and a large surface area. By adding bio-carbon as an interlayer, the battery performed much better, with the capacity increasing by two times. The bio-carbon helped reduce the shuttle current and boosted the battery's performance. When bio-carbon was used both as a scaffold and interlayer, the battery showed even better results, retaining more capacity and having higher efficiency. Even at high charging rates, the bio-carbon-enhanced cathodes performed well, mostly because of how easily the sulfur worked in the jamun seed carbon interlayer.
