A Kansas State University engineer has made a breakthrough
in rechargeable battery applications.
Gurpreet Singh, assistant professor of mechanical and
nuclear engineering, and his student researchers are the first to demonstrate
that a composite paper -- made of interleaved molybdenum disulfide and graphene
nanosheets -- can be both an active material to efficiently store sodium atoms
and a flexible current collector. The newly developed composite paper can be
used as a negative electrode in sodium-ion batteries.
