A team of researchers in MIT are reinventing the battery. Quite interesting .
"A new kind of flow battery is fueled by semi-solid suspensions of
high-energy-density lithium storage compounds that are electrically ‘wired’ by
dilute percolating networks of nanoscale conductor particles. Energy densities
are an order of magnitude greater than previous flow batteries; new applications
in transportation and grid-scale storage may result"
