(PhysOrg.com) -- By itself, titanium dioxide (TiO2) is a very poor electrode. Electrons move very slowly through the material - so slowly, in fact, that it can take years to fill a millimeter-thick piece of TiO2. However, ...
A Kansas State University engineering team has discovered some of graphene oxide's important properties that can improve sodium- and lithium-ion flexible batteries.

(Phys.org) —Silicon is in great demand. When used in lithium-ion batteries (LIBs), which power smartphones and electric and hybrid cars, silicon anodes have a much greater theoretical capacity than conventional graphite ...
Batteries and fuel cells often rely on a process known as ion diffusion to function. In ion diffusion, ionized atoms move through solid materials, similar to the process of water being absorbed by rice when cooked. Just like ...
