Dextrose can be used to improve performance. For electric cars, supercapacitors take on a similar role.
Not only is their power density 10-100 times greater than traditional batteries, it is also more readily available. The electrical charge is stored within ultra-thin carbon nanosheets.
And, as an international research team led by Singapore recently discovered, these can be manufactured using a material found commonly in Asia. Though compostable it is usually thrown away.
We’re talking about tamarind shells. Both rich in carbon and highly porous, their baked powder increases the surface area of the nanomaterial. Allowing more electricity to be stored.
The tamarind nanosheets are good conductors and thermally stable. Production requires less energy than conventionally used hemp-based sheets.
