Contour Energy Systems — the Caltech battery spinout formerly known as CFX Battery — has launched an opportunistic attack on a niche consumer market right in time for Christmas. The Azusa, Calif.-based company has  a line of disposable coin cell batteries specifically engineered for 3D TV glasses, and promises they’ll last about 60 percent longer than competitors batteries. It’s an opportunistic move because it lies outside Contour’s specialized carbon and fluorine-based chemistry — the 3D glasses batteries are lithium-based — and because they’re not being made at Contour’s own factory, but by an unnamed Chinese manufacturer. Still, it may represent the kind of niche application targeting that battery startups may have to tackle to differentiate themselves from the Energizers and Duracells of the world.
