Experimental and theoretical investigations of nitro-group doped porous carbon as a high performance lithium-ion battery anode

Abstract
The lithium adsorption abilities of various functional groups (NH2, NO2, SO3H, Cl, Br, I) are studied by first-principles quantum chemical calculations which are doped at the edge of graphene sheets. Among all the groups, the nitro-group shows the best properties.
