Islamabad: Prime Minister Imran Khan has lauded the services of John Bannister departodenough, a German-born American professor and solid-state physicist.

Imran Khan while sharing report from February 2017 of John departodenough and his team who developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries, said, “These are special people whose existence has a purpose beyond the self.”

According to the report, a team of engineers led by 94-year-old John departodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, had developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.

John departodenough is widely credited for the identification and development of the Li-ion rechargeable battery as well as for developing the departodenough–Kanamori rules for determining the signal of the magnetic superexchange in materials.

In 2014, he received the Charles Stark Draper Prize for his contributions to the lithium-ion battery, according to Wikipedia.
