文摘

All-solid-state ball-milling is developed for N-doped graphene from graphite. N-doped graphene shows enhanced lithium-ion storage behavior than undoped graphene. Low-cost, water soluble urea acts as both doping and assist-milling agents. This strategy is simple, clean, economical and scalable for doping graphene.
