The advance of renewable energy and electric vehicles (EVs) has incentivized scientists to look into various ways to solve the problem with efficient energy storage, which is the key to wider adoption of green energy technologies.
Most previous research has focused on the chemical storage and the electrochemical reactions in batteries.
The mechanical functions of a diamond nanothread (DNT) bundle have the potential to store and release energy when stretched or twisted. These diamond nanothread bundles consist of one-dimensional carbon threads.
"Similar to a compressed coil or children's wind-up toy, energy can be released as the twisted bundle unravels," Dr. Haifei Zhan from the QUT Centre for Materials Science said in a statement.
