A rechargeable battery made from materials sourced from recycled glass bottles has been shown to store almost four times more energy than conventional ones.
Used glass bottles can be ground into a fine powder to create silicon based anodes.
They could improve the battery life of devices such as smartphones and even extend the driving range of electric cars.
HOW THEY DID IT
To create the anodes, the researchers used a three-step process that involves crushing and grinding the glass bottles into a fine white powder.
They then ground the powder with magnesium and heated it up in a chemical reaction, eventually coating the resulting mixture with carbon.
This makes the silicon nanoparticles more stable and boosts their energy storage capacity.
