Greek scientist develops safer, more durable lithium-ion battery that can operate under extreme conditions

22 November 2017

A team of scientists led by Greek researcher Kostas Gerasopoulo at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, has partnered with researchers from the University of Maryland (UMD) and the Army Research Laboratory (ARL) to develop a new type of flexible lithium-ion battery that can operate under extreme conditions, including cutting, submersion and ballistic impact.

“We wanted to show the real implications of this technology in practical applications,” said Kostas Gerasopoulos, senior research scientist and principal investigator at APL. “Particularly for our military, with our [soldiers] exposed to extreme conditions and environments during their missions, the capability to maintain both safety and performance is unprecedented,”

The current generation of flexible batteries shows considerable potential, but they are still in the prototype phase.

“We want to increase the robustness of the [electrolyte] and the energy density of the batteries even further,” Gerasopoulos said. “This work though proves the concept that we can build safe Li-ion batteries that can survive mechanical abuse.”
