Power/Performance Bits: Nov. 23


Increasing lithium battery density Researchers at Columbia University developed a new method to increase the energy density of lithium batteries using a trilayer structure that is stable in ambient air. "When lithium batteries are charged the first time, they lose anywhere from 5-20% energy in that first cycle," said Yuan Yang, assistant professor of materials science and engineering at C... » read more

Graphene-based device enables next-gen energy storage Monash University researchers have brought next generation energy storage closer with an engineering first: a graphene-based device that is compact, yet lasts as long as a conventional battery. A research team in the Department of Materials Engineering has developed a completely new strategy to engineer graphene-based supercapacitors (SC... » read more
