Synthesis, optical and electrochemical performance of CePO4 micro-rods

Abstract

In the present work CePO4 micro-rods with hexagonal prismatic cross-section have been prepared by a facile hydrothermal method. We observe the morphology evolution based on time-dependent experiments. The structure, optical and electrochemical properties of the obtained resultant are studied. Notably, a better electrochemical activity combined with stabilized reversible capacities of 316 mAh g−1 is firstly achieved after 100 cycles at 0.5 mA cm−2, along with an excellent rate capability (300 mAh g−1 at 5.0 mA cm−2), making it a potential prospect in the application of anode material for lithium-ion batteries (LIBs). The capacitive contribution analysis indicates that the electrochemical reaction was dominated by main ion diffusion and partial pseudocapacitive behavior.
