以乙二醇为溶剂和还原剂，采用溶剂热法成功制备了石墨烯/银纳米复合添加剂。系统研究了石墨烯/Ag对Mg-Ni-La非晶合金的表面改性效果。结果表明，电极的放电容量、循环寿命、放电电位特性和电化学动力学性能均得到显著改善。表面改性提高了合金的电催化活性，降低了电极的接触电阻。石墨烯/Ag电极的Mg 65 Ni 27 La 8具有最大放电容量814.8 mAh g-1，是未使用石墨烯/Ag电极的1.33倍，并且具有更好的电化学动力学。
A new graphene/Ag nanohybrid nanocomposite additive was prepared successfully through solvothermal method using ethylene glycol as solvent and reducing agent. The effects of surface modification of amorphous Mg–Ni–La alloy by introduction of graphene/Ag have been systematically investigated. The results showed that the discharge capacity, cycle life, discharge potential characteristics and electrochemical kinetics of the electrodes were all improved significantly. The surface modification enhanced the electrocatalytic activity of the alloy and reduced the contact resistance of the electrodes. The Mg65Ni27La8with graphene/Ag electrode has the largest discharge capacity of 814.8 mAh g−1, which is 1.33 times that of the electrode without graphene/Ag, and the better electrochemical kinetics.
