Graphene scaffold

While lithium metal-based batteries are attractive in theory, practical applications have run into problems ranging from rapid degradation to catastrophic failure. Researchers have tried to overcome these problems by creating a ‘scaffold’ on which lithium ions can be deposited. However, as the volume of lithium ions changes during the charging cycle, expansion can destroy the scaffold.
