We usually only think about them when they need recharging, or when they catch fire. They can be an environmental nightmare if not recycled, and recycling lithium-ion batteries is still problematic.  

So I was intrigued to read about some efforts to rethink what a battery is.

Let’s start with some work done by Swedish tech company Sinonus, a spinout of Chalmers University of Technology and KTH Royal Institute of Technology. The company is all about carbon fiber; more specifically, integrating structural strength and storing energy.

It seeks to make things multipurpose: “Just think of your smartphone, today it seems farfetched to use a single purpose phone, camera and mp3 player when you can have them all in one. In the same way we can transform single purpose materials, such as structure materials and batteries, through our multipurpose carbon fiber composite solution.” 

Or, as TechRadar put it, “how the laptop could become the battery.”
