Scientists from NTU (Nanyang Technological University) have found a way to create components for lithium-ion batteries made using waste paper such as single-use packaging, bags, and cardboard boxes.
First, the researchers carbonise the paper by exposing it to high temperatures. Then they transform the fibres from the paper into electrodes, which can be put to use in rechargeable batteries that can power smartphones or electric cars.
Waste paper makes up around 26 per cent of the rubbish in landfills worldwide. This invention aids in the upcycling and transformation of some paper waste.
Additionally, the recycled paper alternative contributes to the reduction of fossil fuels needed in the production of conventional batteries while cutting down on the overall cost.
The NTU team aims to commercialise within the next five years and has filed for a patent with the University’s innovation and entrepreneurship arm, NTUitive.
