It seems like we're constantly hearing about promising battery technologies that could ultimately lead to longer battery life, more power, and smaller units, but as of yet, that big breakthrough hasn't occurred. Maybe nanotechnology, which is the current hot topic in the battery innovations field, will prove to be different.

Right at this moment, a ton of research is being put into carbon nanotubes (CNTs) for a bunch of uses, including electronics and batteries. Researchers are drawn to CNTs because, according to them, carbon nanotubes are near perfect. That has paved the way for a professor and a UC San Diego graduate student to discover a breakthrough that involves introducing purposeful defects into CNT structures. By doing so, the 'defective' CNTs actually work better for the development of super capacitors, DailyTech reports.

"While batteries have large storage capacity, they take a long time to charge; while electrostatic capacitors can charge quickly but typically have limited capacity. However, super capacitors electrochemical capacitors incorporate the advantages of both," Professor Prabhakar Bandaru said.

The duo also discovered that other methods, such as bombarding CNTs with argon or hydrogen, could also increase or decrease the charge capacity. In the end, the two researchers believe that their discovery could ultimately lead to electronics that charge faster and last longer than what's available today.
