摘　　要：针对传统超电容无法直接作为引信电源使用,是因为充放电速率、比容量以及强度不足的问题,提出了加钾离子及强度支撑体的超电容电源。该电源电极及电解液中添加额外导电离子,降低超电容充放电阻抗,提高超电容的快速充放电性能;电容电极集流体采用支撑体增加强度,提高抗冲击能力。试验表明:超电容满足简单快速的充电条件,较高空载电压持续时间大于450s;单体容量大于2F;放电电流大于100mA时,2V以上超过了30s时间;结构可承受马歇特锤击机23齿冲击,可在引信中应用。Because of the shortages of charging and discharging rate,capacity and strength,the traditional su-per-capacitor power could not be used directly as fuze power.To solve the problem,a new kind of super-capaci-tor based on potassium ions and strength support body was put forward.Potassium ions was added extra in elec-trode and electrolyte to reduce the overall impedance in charging and discharging,and improved the rapid char-ging and discharging performance.At the same time this structure could enhance the impact resistance.Tests showed that a single super-capacitor had a capacity greater than 2F.With the simple speedy charging condition, the no-load voltage could be longer than 450s.When discharging current was more than 100 mA,the voltage o-ver 2 V could last 30 s.this structure could endure 30000g over-load of Hammering Test.
