摘要
针对热电池正极材料氯化镍激活时间偏长、制备工艺复杂等缺点,对氯化镍正极热电池的激活时间、峰值电压、工作时间、负载能力及电极配方等进行了探索,并进行了高温、低温及不同电流密度下常温的放电实验。结果表明,在正极材料氯化镍中添加20%的羰基镍粉对热电池放电初期激活时间的改善是有利的;电解质配方和制备工艺的不同将直接影响氯化镍正极热电池的性能;当电流密度为1.0～1.5A·cm—2时,单体电池的工作电压峰值可以达到2.2～2.4V。
Nickel chloride as anode material for thermal battery is provided with many advantages, such as high voltage, strong loading ability, good thermal stability and etc, meanwhile, long activation time and complex manufacture technology are also involved. Through discharge tests at high,low and normal temperature under different current densities, the article illustrated study on nickel chloride thermal battery about activation time, peak voltage, discharge time, loading ability and electrode composition. Tests prove that adding 20% nickel powder to nickel chloride can improve activation time during discharging initial stage of thermal batteries. The difference in electrolyte prescriptions and manufacture technology will directly effect the performance of nickel chloride thermal battery, peak voltage of cell may achieve 2.2-2.4 V when current density is 1.0-1.5 A·cm^-2.
