【摘要】 以不同原材料,采用共沉淀法制备了锌酸钙。XRD分析显示:合成的锌酸钙与标准样品的结构一致,化学组成为Ca[Zn(OH)3]2·2H2O。对电池进行100周充放电后,电极材料的晶体结构并未发生变化,但晶体尺寸变大。实验表明以硝酸锌和硝酸钙为原料制得的样品具有较小的粒径而显示出较好的充放电性能。更多还原

【Abstract】 Calcium zincate was prepared from various materials by coprecipitation method. The XRD analysis showed that the sample had the same structure as the criterion and the composition was Ca[Zn（OH）₃]₂·2H₂O.The structure of material didn’t charge after 100 cycles, but the particle size was bigger. The result showed that the material prepared from Zn（NO₃）₂·6H₂O,（ Ca（NO₃）₂·4H₂O had the best cyclic performance due to the least particle size.）更多还原
