Lansing, Michigan-based XG Sciences, Inc. announced on 15 October that it had been selected by the US Department of Energy (DOE) to develop lithium-ion battery materials for use in extended range EV applications, leading a team including LG Chem Power, Inc. and the Georgia Institute of Technology.
XG Sciences says its silicon-graphene nanocomposite anode materials have demonstrated significant increases in energy storage capacity over traditional graphite and are manufactured with a “commercially-proven, low-cost process using widely-available and economical starting materials.”
“This DOE contract will accelerate product commercialisation by targeting 600mAh/g reversible anode capacity and 1,000 cycle life in 250mAh cells,” said Rob Privette, XG Sciences’ Vice President, Energy Markets. “Our Silicon-graphene energy storage materials deliver significant improvements in battery cycle life over traditional Silicon-based materials due to a unique and highly-conductive graphene support network. We believe this research will help enable customers to benefit from extended battery run-time in automotive, portable electronics and grid-scale energy storage applications.”
XG Sciences’ energy storage materials are based on the company’s xGnP graphene nanoplatelets and trademarked XG Leaf graphene sheet products that can be formulated into electrodes, with high charge storage and superior current carrying characteristics for batteries, ultracapacitors and fuel cells.
XG Sciences Inc. says it supplies xGnP graphene nanoplatelets as bulk materials and custom graphene-based products to more than 500 customers.
