Abstract

The surface of low voltage formed foil for Al electrolysis capacitors is treated with phosphoric acid solution.The effects of concentration of phosphoric acid solution,temperature and process time on specific capacitance and the time of hydration resistance with standing voltage are studied.The optimum condition is presented.The properties of low voltage formed foil have been improved by applying this method on the product line.
