This rising demand is mainly fueled by increased digitalization, with more industries and consumers adopting digital technologies for communication, automation, entertainment, and data handling. Aluminum foil used in electrolytic capacitors improves electronic device performance by offering high conductivity and efficient energy storage, which ensures stable voltage regulation and power supply. For example, in May 2024, the Japan Electronics and Information Technology Industries Association, a trade organization based in Japan, reported that Japan’s electronic device production reached ¥339,582 million (approximately USD 2.17 billion), up from ¥272,154 million (approximately USD 1.74 billion) in May 2023. Thus, the rising demand for electronic devices is boosting the growth of the aluminum foil for electrolytic capacitor market.

The growth of the electric vehicle (EV) market is also expected to support the expansion of the aluminum foil for electrolytic capacitor market. Electric vehicles are cars powered fully or partially by electricity, typically using rechargeable batteries instead of traditional internal combustion engines. The increasing adoption of EVs is driven largely by environmental concerns, as they produce no tailpipe emissions and contribute to reducing greenhouse gases, thereby promoting cleaner air and climate change mitigation efforts. Aluminum foil for electrolytic capacitors is essential in EVs because it enables compact, high-performance energy storage components that facilitate efficient power conversion and stable electronic control systems. For instance, in December 2024, the U.S. Energy Information Administration, a government agency, reported that the combined market share of hybrid vehicles, plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs) in total new light-duty vehicle sales rose from 19.1% in the second quarter (Q2 2024) to 21.2% in the third quarter (Q3 2024). Therefore, the expansion of the EV market is propelling the growth of the aluminum foil for electrolytic capacitor market.

Key players in the aluminum foil for electrolytic capacitor market are focusing on innovation by developing coated aluminum foil products to boost capacitor performance. These coatings enhance conductivity, increase resistance to corrosion, and support faster charging. Coated aluminum foil refers to aluminum foil covered with a thin layer of protective or functional material to improve its properties. This coating enhances corrosion resistance, electrical conductivity, and adhesion, which is valuable for electrolytic capacitors and battery electrodes. For example, in March 2024, SiAT (Sino Applied Technology Co., Ltd.), a Taiwan-based manufacturer, collaborated with C.S. Aluminum Corporation, also based in Taiwan and specializing in rolled aluminum products, to introduce carbon nanotube (CNT)-coated aluminum foil. This foil is designed to improve fast charging and extend the lifespan of lithium-ion batteries, sodium batteries, and supercapacitors. The CNT coating offers conductivity ten times higher than carbon black, protects aluminum foil from corrosion, strengthens the bond between electrode materials and current collectors, and reduces interface contact resistance, thereby enhancing battery performance. SiAT combines its expertise in CNT nanomaterial dispersion with CSAC’s aluminum foil manufacturing capabilities to deliver high-quality, customizable CNT-coated aluminum foil tailored to specific customer requirements.
