CAP-XX to Sell Ioxus Large Supercapacitor Modules Under Exclusive Marketing Agreement with Ioxus

The companies are teaming to bring Ioxus supercapacitor modules to new geographies, leveraging CAP-XX’s distribution infrastructure in EMEA, APAC, Mexico, Central and South America, Australia and New Zealand

Sydney, Australia – August 4, 2022 – CAP-XX Limited (LSE:CPX), the leading manufacturer of ultra-thin prismatic, cylindrical, and Lithium-Ion supercapacitors, has entered a joint marketing agreement with Ioxus to bring Ioxus supercapacitor modules to new geographies by leveraging CAP-XX’s strong worldwide distribution and sales networks. CAP-XX will sell CAP-XX-branded versions of Ioxus supercapacitor modules in EMEA, APAC, Mexico, Central America, South America, Australia and New Zealand. Ioxus will continue to sell its supercapacitor modules in North America and Japan.

The large, powerful Ioxus supercapacitor modules are designed for power management in demanding applications such as transportation subsystems, engine start modules, regen energy capture, microgrid/grid/power correction, UPS/ride through power, wind turbine pitch control and hybrid energy storage.  CAP-XX will sell all 22 of Ioxus’ customer-configurable modules, branded as CAPMOD, as well as uSTARTs, branded as CAPSTART.

Ioxus modules, made using large 3000F cylindrical supercapacitor cells, boast a high voltage range (up to 2000V), can deliver and absorb a high current, can perform under a wide range of climate conditions, and offer the highest life cycle in the market. They will accelerate CAP-XX’s ability to enter a number of fast-growing markets including:

  • Electric vehicles
  • Regenerative braking and energy recycling for vehicles and heavy equipment
  • Vehicle engine starting
  • Wind turbines
  • Solar installations and other microgrid applications
  • Grid Energy Storage and Stabilization

“We are excited about this synergistic agreement, which gives us a range of powerful supercapacitor modules and truck start modules to access new markets in demanding microgrid applications, and gives Ioxus a geographic sales path where CAP-XX is already well established,” said Anthony Kongats, CEO at CAP-XX.

“This is a win-win agreement, allowing us to expand our market coverage through CAP-XX in geographies where we don’t have a physical presence,” said Scottie Johnson, CEO at Ioxus.
