【摘要】 以机械混合及浸渍法分别将不同含量的氧化铈和氯化混合稀土加入EMD中,在不同温度下作前处理。用X射线衍射和热分析仪对其物相和氧化度(MnOx)X进行了分析和测定,并结合制成实用电池进行了放电实验和比较。结果表明:在EMD中加入适量此类添加剂,可明显提高电池的放电时间,热行为也与未加的显著不同。加入两类不同添加剂时,负极产物相同,正极产物不同。加入的氧化铈,电池反应后仍以原有形式存在。更多还原

【Abstract】 Two different anode materials were prepared by machamcal mixing and solution wetting of rare earth or mixture of rare earth compounds with EMD. The materials obtained were treated under various temperatures. The phase components and the degree of oxidation of Mn were analysed by X-ray diffraction, DSC and TG. The results were compared with the discharge characteristics of the materials. Optimum amount of additives and treating temperature were determined.更多还原
