Maxwell Technologies Inc. has formed a toll manufacturing alliance with Belton Technology Group, a major Chinese manufacturer of precision components, flex circuits, circuit boards and other products, to support Maxwell's BOOSTCAP ultracapacitors and multicell modules for automotive and other markets.

Maxwell president and chief executive officer Dr. Richard Balanson said the alliance enables his firm to tap into Belton's large factories, supply chain operations and 20,000-person skilled production workforce to ensure that Maxwell can ramp ultracapacitor production as required. He said that Maxwell will continue to produce its proprietary carbon powder electrode material internally and deliver it to Belton plants for assembly into finished ultracapacitor cells and modules.
