Researchers from Hydro-Québec and the US Army Research Laboratory (ARL) used a new high-voltage cathode to produce what they say is the world’s first 5 V, 1.2 Ah Li-ion cell. According to ARL scientists Jan Allen and Richard Jow, who published their findings in the Journal of Power Sources, the cells enable higher energy densities and improved designs for battery-powered devices.

“With the high voltage of this new cell, we can reach a very high energy density,” says Hydro-Québec’s CETEES General Director Karim Zaghib. “This highly desirable property can improve batteries used in a wide range of applications.”
