Achieving a supercapacitor through the ‘molecular coating’ approach

Posted by in categories: materials, mobile phones

Researchers at Tohoku University have successfully increased the capacity, lifetime durability, and cost-effectiveness of a capacitor in their pursuit of a more power-efficient future. The research is published in the journal ACS Applied Materials & Interfaces.

A capacitor is a device used as part of a circuit that can store and release energy, just like a battery. What makes a capacitor different from a battery is that it takes much less time to charge. For example, your cellphone battery will power your phone instantly, but charging that back up to 100% when it dies is far from instantaneous.

While this makes capacitors sound like the superior choice, they have some big drawbacks that need to be overcome. First, their is much smaller than batteries, so they cannot store large amounts of energy at once. Second, they can be quite expensive.
