II-VI Incorporated Introduces Lithium-Sulfur/Selenium Cathode Technology for High-Energy and High-Power Lithium-Ion Batteries

II-VI invited to present at Battery 500 Consortium workshop on next-generation lithium metal batteries

II‐VI Incorporated (Nasdaq: IIVI), a leader in engineered materials, today announced that it will introduce its lithium-sulfur/selenium cathode technology for high-energy and high-power lithium-ion batteries at the Li Metal Battery R&D, Manufacturing and Supply Chain Workshop hosted by the Battery 500 Consortium. 

Dr. Chris Koeppen, Chief Technology Officer, will present the recent progress in II-VI’s seven years of development of lithium-sulfur/selenium materials for cathodes, which are compatible with high-capacity anodes and emerging solid-state electrolyte chemistries for Li-ion batteries. II-VI’s proprietary cathode technology has the potential to significantly enhance the performance of lithium-ion batteries for ground, sea, and air transportation infrastructures; the deployment of energy storage at scale; and consumer electronics. II-VI’s cathode technology is free of cobalt, a designated conflict mineral.

“We are excited about the high performance of our cathode technology in battery cell testing, and we look forward to sharing the results at the workshop with major battery end users and technology experts,” said Dr. Koeppen. “II-VI’s cathode technology can be tailored to the application by adjusting the mix of sulfur and selenium: Greater sulfur content maximizes energy storage while greater selenium content maximizes power delivery and reduces charging time.”

Pacific Northwest National Laboratory (PNNL) of the U.S. Department of Energy leads the Battery 500 Consortium. Participants in this workshop include various invited end users and companies involved in the supply chain of emerging battery technology.

II-VI is also currently exhibiting at the Virtual Battery Exhibition until May 3, 2021. For more information, visit http://virtualbatteryexhibition.de/.
