Flexible nitrogen-doped graphene/SnO2 foams promise kinetically stable lithium storage

The balanced design of flexible nitrogen-doped graphene/SnO2 (NG-SnO2) foam with an integrated film structure on a macroscale and interconnected micro-/nano-porous architecture on a microscale triggers a novel synergistic electrochemistry on Li storage, leading to kinetically-stable Li-storage performances.252
