If you want a smartwatch with week-long battery life, then you're better off with something like Pebble than a color touchscreen watch – they typically only last a day or two. But South Korea's LG Chem, the country's largest chemical company and part of the same corporate LG umbrella that also makes smartphones like the LG G4 and the LG G Watch Urbane smartwatch, reportedly has taken a step towards addressing the issue with a new hexagonal smartwatch battery.

LG said on Sunday that it had begun making the coin-sized batteries at its large battery factory in China and that it plans to begin selling them to tech companies around the world. It claims the hexagonal design, which improves storage capacity by 25 percent over rectangular batteries and is a better fit for round smartwatches, is an industry first.

The battery was reportedly developed through a collaboration with another large technology company that LG declined to identify, although Apple and LG Electronics are said not to be the collaborator. LG has recently prided itself on producing flexible batteries in novel shapes and sizes, an effort it refers to as its "free form battery" division.

If the company's claims hold true, the new battery will mean about an extra four hours of use per charge for smartwatch users. It expects more companies to introduce round-face smartwatches this year.

So far, round watches like the Moto 360 and LG G Watch Urbane have received some degree of critical acclaim, but have yet to become major bestsellers.
