Chemists create carbon materials for energy storage device from brewery waste

Modern energy storage systems are an important building block for a climate-friendly future. “Modern” means not only that their performance meets the demands of a high-tech society, but also that they can be produced and recycled sustainably. In the search for new resources, scientists sometimes hit upon surprising raw materials—for example brewery waste.

Improving the durability of lithium metal batteries using carbon fiber paper as the anode

Due to the worldwide growth of electric vehicles, there has been a rise in demand for next-generation secondary batteries with higher capacity and faster charging than the lithium-ion batteries currently in use. Lithium metal batteries have been recognized as promising rechargeable batteries because a lithium metal anode exhibits a theoretical capacity 10 times higher than a commercial graphite anode. During charging-discharging processes, however, lithium dendrites grow on the anode, leading to poor battery performance and short-circuits.
