摘要: 应用共沉淀的方法在球型Ni(OH)2的表面包覆了一层Y(OH)3,并研究了包覆不同含钇量后的球型Ni(OH)2的高温充放电性能。研究结果表明:包覆Y(OH)3的球型Ni(OH)2具有良好的高温充放电性能。其中1C充放电条件下,包覆量为0.3%的Ni(OH)2较好,0.2C充放电条件下,包覆量为1%的Ni(OH)2较好。

Abstract: Spherical Ni(OH)2 coated with Y(OH)3 was prepared,and the effects of the crystal structures of yttrium compounds to the high-temperature properties of the spherical Ni(OH)2 was studied.The results show that the specific capacities of the spherical Ni(OH)2 coated with Y(OH)3 are higher than that of the regular at high temperatures.At 0.2C charge/ discharge rate the specific capacity of Ni(OH)2 coated with 1% Y(OH)3 is 60% higher than that of the regular. At 1C charge/discharge rate the specific capacity of Ni(OH)2 coated with 1% Y(OH)3 is 10% higher than of the regular.
Keywords: spherical Ni(OH)2 Y(OH)3 coat charge/discharge capacities
