摘要:
铝电解电容器是具备性能优良、大容量、价格低廉的优点被广泛应用于光电产品、消费电子产品、军事装备、髙速铁路、航空及汽车工业等领域的一种高性能储能元件。随着铝电解电容器的广泛应用,对于阳极箔的要求越来越高,特别是耐630 V的超高压阳极箔。选择六偏磷酸钠(SHMP)作为磷酸盐缓蚀剂,研究了其对高压铝阳极箔的作用机制。采用质量损失测试法、电化学阻抗谱(EIS)和动电位极化测量技术分析了缓蚀剂加入对铝箔腐蚀机制及阳极箔比电容的影响。结果表明:在2 mol/L HNO3溶液中制备高压铝阳极箔时,六偏磷酸钠是一种阴极型缓蚀剂; 当六偏磷酸钠质量分数为0.10%时,缓蚀效果最优,比电容达到最大值为0.692 μF/cm2,较未加入缓蚀剂增加了9.4%。
Abstract:
Because of excellent performance, high capacity and low cost, the energy storage component aluminum electrolytic capacitor is widely used in optoelectronics, consumer electronics, military equipment, idle rail, aviation and automotive industry fields. With the widely used of aluminum electrolytic capacitors, the demand for anode foils is becoming higher and higher, especially in 630 V super-voltage anode foils. Sodium hexametaphosphate(SHMP)were selected as polyphosphate corrosion inhibitor to investigate the action mechanism on high voltage anodic foil. Effects of corrosion inhibitor on the corrosion mechanism of aluminum foil and the special capacitance of the anode foil were analyzed by mass loss, electrochemical impedance spectroscopy(EIS)and potentiodynamic polarization measurements. Results showed that SHMP was a cathodic corrosion inhibitor in the preparation of high pressure aluminum anode foil in 2 mol/L nitric acid solution, and the special capacitance was up to 0.692 μF/cm2 with an increasing nearly by 9.4% for 0.10%(mass ratio)SHMP.
