We are a top manufacturer of electric double-layer capacitors (EDLC) that are rapidly increasing in demand worldwide! We also offer high-performance batteries from XSP.

Ioxus is a comprehensive energy storage device manufacturer that handles everything from capacitors to batteries. Starting as a top manufacturer of electric double-layer capacitors (EDLC), since its establishment in North America in 2007, it has advanced the development and mass production of EDLCs, raising output density and energy density to the highest levels in the industry. As the only manufacturer in the industry to mass-produce cylindrical (iCAP) cells and pouch (THiNCAP) cells, we offer a wide range of products tailored to our customers' needs. EDLCs are safe energy storage devices with rapid charge/discharge characteristics and ultra-long lifespan properties. Leveraging unique features not found in other energy storage devices, Ioxus has provided solutions for a wide range of applications, including UPS, AGV transport, hybrid buses, peak-cut power supplies, and jump starters. In recent years, we have also been adopted in new markets such as renewable energy, grids, and nuclear fusion. Ioxus will continue to develop its unique technology protected by IP, providing more user-friendly and high-performance products to the market. Since 2020, we have started supplying high-performance batteries manufactured by XSP, including AGM lead batteries and lithium-ion batteries.
