“Dennis brings a compelling blend of strategic and financial knowledge with a successful career at both a multi-national technology organization and an energy sector start-up. which he helped propel into a $1B public company,” said 6K CEO, Dr. Aaron Bent. “He will play a key role as 6K transitions to its next stage of corporate development and expands our UniMelt® technology in the battery and additive manufacturing markets.”

“6K has made tremendous progress on its growth strategy with significant opportunity ahead in both battery and additive manufacturing markets,” said Fehr. “I’m excited to help advance 6K’s business as customers, policymakers, and investors increasingly recognize the importance of clean technology and the necessity of a domestic supply chain of critical materials. I look forward to partnering with 6K leadership to drive growth and create value for our shareholders.”

Mr. Davies is an experienced strategic and operational leader – this appointment follows a ten-year career at Cabot Corporation, where he was responsible for the industrial performance of eighteen global carbon black plants and chaired the company’s Manufacturing Council. At 6K Energy, Rob will oversee manufacturing expansion, including the full scale PlusCAM™ cathode material production scheduled to open in 2025, which is funded in part by the recently awarded $50M Department of Energy grant from the Bipartisan Infrastructure Law. 

Sam Trinch, 6K Energy president, added, “The appointment of Rob catapults 6K Energy into a new phase of our growth journey. With the inception of the COO role, I’m confident this will provide the leadership and vision to grow 6K Energy into the leading domestic supplier of battery materials. Having Rob on board gives us a high-velocity operating model and manufacturing vision that will empower our people to deliver an unmatched supply chain of material to our customers and partners as we scale up operations.”

“With the depth of industry knowledge, impressive growth strategy, and strong instincts for innovation and supply chain readiness, 6K Energy is poised for a powerful upward trajectory,” said Davies. “I am enthusiastic about the future of 6K Energy, and I look forward to leading the manufacturing expansion of the organization across the battery material industry.”
