Natural structures in reed leaves could find use in advanced lithium-ion batteries, which could lead to a more sustainable way to create sophisticated energy-storage devices, scientists in China and Germany say.

Silicon-based materials can theoretically store more than 10 times charge than the carbon-based materials most commonly used in the anodes of commercial lithium-ion batteries, making them promising next-generation anode materials. However, silicon’s big...
