铁镍蓄电池Fe2O3负极材料的制备及添加剂的研究

Study on preparation and additives of Fe2O3 anode material for Fe/Ni battery

通过焙烧七水合硫酸亚铁制备Fe2O3负极材料,确定了最佳热分解温度,同时研究了金属硫化物添加剂对铁镍蓄电池放电性能的影响。结果表明:以900热分解制得的Fe2O3,在加入多种金属硫化物添加剂时,放电比容量均显著提升。

Fe2O3 anode material was made by calcination of FeSO4·7H2O.The best calcination temperature was determined,and the influence of metal sulfide addition to the anode on the discharge performance of Fe-Ni battery was studied.The results show that Fe2O3 calcined at 900℃ when several metal sulfide was added to the anode,discharge specific capacity is significantly improved.
