The diatium power cell was a power source. They were suitable to be used as the primary power source in lightsabers. The first lightsaber Obi-Wan Kenobi wielded as a Jedi used one, which was surrounded by the notched hand grip. Darth Vader's lightsaber used a high-output diatium power cell. Darth Vader's grandson Ben Solo also used a lightsaber with a bronze colored diatium power cell cradled in its handle during his training with Luke Skywalker's reborn Jedi Order and after his fall to the dark side as Kylo Ren.
