We're resigned to the fact that the constantly increasing power demands of modern gadgets will always outstrip slow increases in the energy density of batteries: however, high energy density is not the only factor that goes into making a good battery.

This type of battery has an unusually high energy density, which means the units can be smaller and thus lighter for a given amount of power than traditional batteries.
