There are fewer manufacturers of domestic electrolytic capacitor aluminum foil, mainly because the market demand is not large, and the production technology has a big gap with advanced countries. However, aluminum electrolytic capacitors have good performance, low price and wide application, so the market prospect is very good. At present, Japan's annual demand is 45,000 tons, which is six times that of the Chinese market. With the development of the electronics industry and China becoming a major industrial production base, the market demand for electrolytic capacitor aluminum foil is broad.
