文摘

Three-dimensional porous LiFePO4/N-CNTs is synthesized by a freeze-drying method. The N-CNTs conductive network enhances the electron transport within the LiFePO4 electrode. The continuous pores accelerate the diffusion of lithium ions. LiFePO4/N-CNTs demonstrates an excellent electrochemical Li-insertion performance.
