(April 18, 2015) The
key to better cellphones and other rechargeable electronics may be in tiny
"sandwiches" made of nanosheets, according to mechanical engineering
research from Kansas State University.
Gurpreet Singh, assistant professor of mechanical and
nuclear engineering, and his research team are improving rechargeable
lithium-ion batteries. The team has focused on the lithium cycling of
molybdenum disulfide, or MoS2, sheets, which Singh describes as a
"sandwich" of one molybdenum atom between two sulfur atoms.
