Safety concerns regarding lithium-ion batteries have been making headlines in light of smartphone fires and hoverboard explosions. In order to combat safety issues, at team of researchers from Drexel University, led by ECS member Yury Gogotsi, has developed a way to transform a battery’s electrolyte solution into a safeguard against the chemical process that leads to battery fires.
Dendrites – or battery buildups caused by the chemical reactions inside the battery – have been cited as one of the main causes of lithium-ion battery malfunction. As more dendrites compile over time, they can breach the battery’s separator, resulting in malfunction.

As part of their solution to this problem, the research team is using nanodiamonds to curtail the electrochemical deposition that leads to the short-circuiting of lithium-ion batteries. To put it in perspective, nanodiamond particles are roughly 10,000 times smaller than the diameter of a single hair.
