The reasonable design of nanostructure is the key to solving the inherent defects and realizing a high performance of Li2FeSiO4 cathode materials. In this work, a novel heterostructure CNT@Li2FeSiO4@C has been designed and synthesized and used as a cathode material for lithium-ion battery. It is revealed that the product has a uniform core-shell structure, and the thickness of the Li2FeSiO4 layer...
A core-shell graphene nanosheets (GNS) and amorphous carbon composite (GNS@a-C) was prepared by a chlorination method and used as a highly efficient catalyst support for oxygen reduction reaction. Herein, GNS as a shell, with excellent conductivity, high surface area, and corrosion resistance, served as a protecting coating to alleviate the degradation of amorphous carbon core. Platinum nanoparticles...
