NiCoO2@FC复合材料的制备及储锂性能研究
Preparation and Lithium Storage Properties of NiCoO2@FC Composites
摘要
Abstract
In this paper,NiCoO2@fluorocarbon(NiCoO2@FC)composite is prepared using the hydrothermal method combined with an annealing process,which is applied to the anode of a lithium-ion battery.The electrochemical results show that the reversible specific capacity of the NiCoO2@FC composite remains at 663.8 mA·h·g-1 after 100 cycles,which is significantly high-er than that of NiCoO2(482.8 mA·h·g-1).The improved electrochemical performance of the composite is attributed to the coating of the fluorocarbon coating.Fluorocarbon provides a good con-ductive network,which promotes the transport kinetics of lithium ions and electrons.Moreover,it also provides more active sites by introducing carbon defects,thereby improving the specific capaci-ty of the composite.This work provides a design strategy for preparing anode materials with good electrochemical performance for lithium-ion batteries.关键词
