Electrochem is proud of our roots which stem from founder Wilson Greatbatch’s invention of the first lithium battery for use in implantable pacemakers in the early 1970s.

In 1958, Mr. Greatbatch was working on an oscillator to aid in the recording of tachycardias when he inadvertently connected a 1 MΩ resistor instead of a 10 KΩ resistor to a circuit. He immediately recognized that this lower electrical current could power the implantable pacemaker he was designing and could ultimately drive a human heart.

That inadvertent resistor discovery led to Mr. Greatbatch’s invention and patent of the lithium battery design for pacemakers.  In 1970 he formed Wilson Greatbatch Ltd., the grandfather company of Electrochem, an Integer company.
