Developing high-performance, robust, and economic supercapacitor is a promising path to the future electric vehicle’s technology. Herein, a hierarchically porous CeO2 micro rice was attached on the Ni foam surface...
A graphene-like N-doped hierarchical porous carbon array on a 3D metal substrate is obtained by a green and one-step vacuum de-metal assisted carbonization process for high performance potassium-ion batteries.
Self-supporting carbon fibers with unique hierarchical porous structures and abundant Fe/N adsorption–nucleation centers enable the construction of high performance Li–S batteries.
1D oriented ordered cross-linking hierarchical porous carbon fibers were fabricated successfully. The prepared cross-linking hierarchical porous carbon fibers (CHPCF) as the sulfur immobilizer demonstrated excellent cycling stability and high C-rate performance in Li–S batteries.
