Phys.org  October 25, 2022 Metal batteries that directly use active metals as anodes are promising solutions for energy upgrade of battery technologies, but they suffer from dendrite problems. Researchers in China have demonstrated that functional carbon materials (FCMs) can suppress metal dendrites. They reviewed recent progress in using FCMs to deal with dendrite problems. The review focused on the surface chemistry and multi-dimensional carbon material engineering, which systematically overcomes the problems through diverse methods, such as reinforcing desolvation, improving interface compatibility, homogenizing electric field, buffering volume expansion and lattice mismatch. They refined the long-standing debate about whether surface defects in […]
