【摘要】 研究了预热处理温度、时间以及沉积纳米氧化铝膜对低压铝箔化成比电容的影响。结果表明,铝箔沉积纳米氧化铝膜并进行适当热处理,在20V电压化成后铝箔的比电容比传统化成和预热处理后进行化成的比电容有显著提高,最大比电容提高幅度近30%,形成时间降低90%以上。更多还原

【Abstract】 The influence of preheat treatment and depositing nano-alumina films on the specific capacity of Al foil for 20V capacitor was researched.It is shown from the experimental results that the specific capacity of Al foil is markedly increased by formation at 20V with pre-heat treatment and depositing nano-alumina films compared with the traditional formation process,in which the maximum extent for the increase of the specific capacity is near 30%,while the decrease of formation time is over 90%.更多还原
