High-Performance Cathode Material of FeF(3)·0.33H(2)O Modified with Carbon Nanotubes and Graphene for Lithium-Ion Batteries
The FeF(3)·0.33H(2)O cathode material can exhibit a high capacity and high energy density through transfer of multiple electrons in the conversion reaction and has attracted great attention from researchers. However, the low conductivity of FeF(3)·0.33H(2)O greatly restricts its application. General...

description | The FeF(3)·0.33H(2)O cathode material can exhibit a high capacity and high energy density through transfer of multiple electrons in the conversion reaction and has attracted great attention from researchers. However, the low conductivity of FeF(3)·0.33H(2)O greatly restricts its application. Generally, carbon nanotubes (CNTs) and graphene can be used as conductive networks to improve the conductivities of active materials. In this work, the FeF(3)·0.33H(2)O cathode material was synthesized via a liquid-phase method, and the FeF(3)·0.33H(2)O/CNT + graphene nanocomposite was successfully fabricated by introduction of CNTs and graphene conductive networks. The electrochemical results illustrate that FeF(3)·0.33H(2)O/CNT + graphene nanocomposite delivers a high discharge capacity of 234.2 mAh g(−1) in the voltage range of 1.8–4.5 V (vs. Li(+)/Li) at 0.1 C rate, exhibits a prominent cycling performance (193.1 mAh g(−1) after 50 cycles at 0.2 C rate), and rate capability (140.4 mAh g(−1) at 5 C rate). Therefore, the electronic conductivity and electrochemical performance of the FeF(3)·0.33H(2)O cathode material modified with CNTs and graphene composite conductive network can be effectively improved. |
