Solvent engineered synthesis of layered SnO for high-performance anodes

Abstract Batteries are the most abundant form of electrochemical energy storage. Lithium and sodium ion batteries account for a significant portion of the battery market, but high-performance electrochemically active materials still need to be discovered and optimized for these technologies.
