A binder-free sulfur/reduced graphene oxide aerogel as high performance electrode materials for lithium sulfur batteries

Societies' increasing need for energy storage makes it necessary to explore new concepts beyond the traditional lithium ion battery. A promising candidate is the lithium-sulfur technology with the potential to increase the energy density of the battery by a factor of 3-5. However, so far the many problems with the lithium-sulfur system have not been solved satisfactory. Here we report on a new ...

Graphene oxide based conductive glue as a binder for ultracapacitor electrodes†

An adhesive and conductive glue was created by synergistic assembly of graphene oxide (GO), single walled carbon nanotubes (SWCNTs) and conjugate polymer PEDOT:PSS in aqueous solution. The GO–SWCNTs–PEDOT:PSS glue can be used as a binder to fabricate metal oxide nanoparticle based ultracapacitors. Since the functional nanoparticles are immersed in this conductive gel, uniform electrical and mec...

3-D binder-free graphene foam as a cathode for high capacity Li–O2 batteries

To provide energy densities higher than those of conventional Li-ion batteries, a Li–O2 battery requires a cathode with high surface area to host large amounts of discharge product Li2O2. Therefore, reversible formation of discharge products needs to be investigated in Li–O2 cells containing high surface area cathodes. In this study, a binder-free oxygen electrode consisting of a 3-D graphene s...
