镁离子电池正极材料VS4制备及电化学性能
Preparation and electrochemical performance of VS4 cathode material for magnesium ion battery
摘要
Abstract
Recent progress in the field of energy storage has led to growing interest in magnesium ion batteries(MIBs).As an emerging energy storage technology,magnesium is abundant in resources,cost-effective,environmentally friendly,and less prone to dendrite formation during charging and discharging,making it a promising alternative to traditional lithium-ion batteries with better safety.Sulfide-based positive electrode materials typically exhibit high theoretical specific capacitance and good conductivity,making their research crucial for enhancing the performance of magnesium ion batteries.VS4 has a special atomic chain structure,a unique structure,high capacity,and long cycle life,which has attracted much attention.This study syntheses VS4 using the solvothermal method.A four-factor three-level orthogonal experiment is designed to investigate the effects of hydrothermal temperature,hydrothermal time,raw material ratio,and solvent ratio on the microstructure and size of the material.Nine groups of synthesized materials are made into electrode sheets,and magnesium foil is used as the negative electrode.A fully phenyl complex(APC)has been used as the electrolyte to assemble a magnesium ion battery for electrochemical performance testing.It is revealed that sample S3 exhibits the most compact particle size and superior electrochemical properties,reaching 369.1 mAh/g in the first discharge process.Even after 110 charge and discharge cycles,the specific capacity of the material can still be maintained at 80.1 mAh/g,showing good cycle stability.Experimental results have shown that different preparation conditions affect the microstructure and size of materials.Optimizing preparation conditions is beneficial for improving the electrochemical performance of magnesium ion batteries.关键词
