Meet the ChemE alum who invented the modern-day battery

In 1959, the late Lewis Urry (5T0) invented the zinc manganese dioxide alkaline battery. It remains one of the most significant advancements in the battery’s history.

Mr. Urry, who worked for Toronto-based Canadian National Carbon Co. at the time, was tasked with discovering a way to extend the life span of the commonly used zinc-carbon battery. He took a novel approach to the problem: he tested cells that used acid-neutralizing or ‘alkaline’ materials.
