The Breakthrough

The team can create cellulose foam in a one-step process using cellulose nanocrystal. According to, it looks like uncooked minuscule rice grains. The team was able to glue together the rice grains at random points to create a mesh structure, which can produce more sustainable capacitors devices as compared to rechargeable batteries.

The Implications

Cellulose-based capacitors could be significantly more sustainable than current capacitor technology. In particular, they could be used for the batteries that power hybrid and electric cars. Gadgets as well as future power consumption patterns will require better batteries. This research might point one way to get there.
