Use Intentionally Blemished Graphene Paper To Create Easy-To-Make,
Quick-Charging Lithium-ion Battery With High Power Density
Engineering researchers at Rensselaer Polytechnic Institute
made a sheet of paper from the world’s thinnest material, graphene, and then
zapped the paper with a laser or camera flash to blemish it with countless
cracks, pores, and other imperfections. The result is a graphene anode material
that can be charged or discharged 10 times faster than conventional graphite
anodes used in today’s lithium (Li)-ion batteries.
