Scientists have created a biodegradable paper battery that could help reduce the thousands of tons of regular batteries that end up in the landfill. The battery itself is a hybrid “biobattery” that uses a mixture of paper and engineered polymers.
The polymers are the key to making the battery biodegradable and mean it can break down in water without any special facilities or chemicals. The batteries are lightweight, cheap and flexible, and it is their flexibility that is central to their success: the power of the battery can be improved by simply folding or stacking it.
According to the team behind the batteries – at Binghampton University, State University of New York – they are easy to produce, modify and configure. Each year we dispose of billions of batteries around the world, all of which contain potentially toxic or corrosive materials.
Professor Sean Choi said: “There’s been a dramatic increase in electronic waste and this may be an excellent way to start reducing that.
