Graphene advance for Li-ion batteries

Graphene has been cited as the saviour of lithium-ion rechargeable batteries for a while now. As an incredibly thin substance, it can massively increase the surface area of an electrode and thus increase the energy density of a battery. The big snag, however, is what researchers call pulverisation: the damage that these very flimsy nanostructured electrodes incur during recharging cycles.

Now, though, a team at the University of Science and Technology in China has managed to prevent the issue of pulverisation by using atom-thick cobalt oxide.
