中文摘要
    论述了活性炭超级电容器材料充放电性能的测试方法步骤和测试结果,在此基础上,通过模拟,确定放电电流随时间的变化规律。建立物理模型,用固体物理理论,从微观角度研究材料的电阻随温度的变化,进而得到活性炭超级电容器材料放电电流强度随温度和放电时间变化规律的解析式,探讨材料原子的非简谐振动对电极材料放电性能的影响。结果表明:(1)电极材料放电电流随时间的变化并不遵从将它作为线性元件处理时的按时间的负指数规律变化,而是非线性减小,减小的情况与温度有关;(2)活性炭超级电容器材料的电阻随温度升高而增大。增大情况与原子振动情况有关:将原子振动作简谐近似处理时,材料的电阻的倒数几乎与温度成反比,考虑到原子非振动后,其电阻随温度升高而增大的情况加剧, 温度愈高,非简谐振动项的影响愈大;(3)本文提出的物理模型和采用的理论,能对活性炭超级电容器电极材料放电性能进行有效的研究。
英文摘要
    This paper discusses test method, step, and result for charge-discharge performance of active carbon super capacitor material, and determines variation law of discharge current with time according to solid-state physics. It obtains analytic expression of discharge current intensity variation law of active carbon super capacitor material with changes of temperature and discharging time after established physical model according to solid state physics and researched changes in material resistance with different temperature from microcosmic angle, furthermore, it explores influence of non-simple harmonic oscillation of atomic material on discharge performance of electrode material. The result shows as follows: Firstly the changes of electrode material discharge current with time reduce nonlinearly rather than obey the negative index change with time when it is considered as linear element, and the reduction is related to temperature. Secondly the resistance of active carbon super capacitor material increases when temperature is raised. The increase is related to atomic vibration, when atomic vibration is in approximate harmonic process, reciprocal of material resistance is almost in inverse ratio with temperature, resistance increases obviously with the temperature increase after atomic non-vibration is considered, the influence of non-harmonic vibration is larger when temperature increases higher. Thirdly the physical model and theory discussed in this paper can help researching charge-discharge performance of active carbon super capacitor material effectively.
