Hierarchical holey reduced graphene oxide–carbon quantum dot hybrid conductive additives enabling high-rate and long cycle life LiFePO 4 cathodes

Graphene oxide was etched with H 2 O 2 , mixed with carbon quantum dots and annealed to prepare HRGO/CQDs composite. Its stable holey structure and active sites make it a promising high-rate conductive additive for long cycle life LiFePO 4 batteries.
