摘要
An hierarchical porous graphene material is readily fabricated via CaO-templated chemical vapor deposition for the first time. Microsized in-plane vacancies, mesosized wrinkled pores, and macrosized strutted cavities render the as-obtained material a favorable scaffold for lithium–sulfur battery cathodes with superior rate capability, high coulombic efficiency, and excellent stability. A remarkable capacity of 357 (656 ) is manifested at a high current rate of 5.0 C, exhibiting a 74% retention of the capacity at 0.1 C.
