摘　　要：采用溶剂热法合成Ni(OH)_2/C复合电极材料,研究C对复合电极材料电化学性能的影响。测试结果表明,产物为片状不规则外观,且Ni(OH)_2未发生晶型结构改变,Ni(OH)_2/C复合电极材料表现出较好的电化学性能,首次放电比容量达到185.0 F·g^(-1)。当测试电流密度为0.5A·g^(-1)时,充放电循环200次后的比容量保持率为92.5%,说明复合材料具有较好的循环稳定性。The Ni(OH)2/C composite electrode material was synthesized by solvent thermal method and the effect of C on the electrochemical properties of composite electrode materials was studied.Test results showed that the product had an irregular appearance,and the crystal structure of Ni(OH)2 was not changed.The Ni(OH)2/C composite electrode material showed good electrochemical performance with the discharge capacity of the first time reaching 185.0 F/g.When the test current density was 0.5A/g,the specific capacity retention rate after 200 charge and discharge cycles was 92.5%,indicated the composite material had good cyclic stability.
