Maxwell Technologies is a pioneering global leader in developing, manufacturing and marketing ultracapacitors, with millions of units now performing reliably around the clock worldwide. Ultracapacitors are energy storage and power delivery products that enable design engineers to create systems that optimize energy efficiency, performance, reliability and cycle life. We have been developing and producing power products since 1965, and have invested more than $100 million in research and product development that today translates into solutions that meet the stringent requirements of a broad range of electrical energy applications. Maxwell’s investments in research and development are protected by more than 100 issued U.S. patents and pending patent applications.
A critical element of Maxwell ultracapacitors’ industry-leading cost position and unparalleled longevity and performance lies in our proprietary electrode fabrication process. Through this unique, environmentally compatible, solvent-free process, high-purity activated carbon powder is formed into carbon film and laminated onto aluminum foil substrate to produce super-capacitive double-layer electrode material. Wound or folded electrode and separator material are then sealed in a robust, hermetically sealed package and impregnated with high-performance electrolyte. The resulting ultracapacitors are extremely durable, maintenance-free products in a variety of form factors and capacitance ratings to meet the needs of applications ranging from hand-held devices to hybrid transit buses, wind turbines and more.
