Wearables: great, apart from the fact that batteries last about five minutes. Samsung, though, may have a solution: it's just announced a new type of battery which is so flexible that it can be rolled up into a hoop.

The announcement, made at InterBattery 2014 in Seoul—how about that for an expo name?—claims that the new style of battery can work even when it's rolled up into the shape of a paper cup. While details are scant according to a report by G for Games, the new flexibility apparently stems from changes in structural design and improved materials.

It may be a little early to get too excited though: these things certainly aren't ready for the masses yet. Indeed, the reliability of the cells is apparently still low, which suggests that, even if they do work when deformed, that performance doesn't last for long.

G for Games claims that "reports claim that the units will be commercially available within the next three years." But, even if that's accurate, three years is quite a long time; flying cars might exist in three year's time, to be honest. Still, it's a leap forwards in terms of battery design—let's just hope it arrives, from Samsung or anyone else for that matter, sooner than those reports suggest. [G for Games]
