Eos Energy Enterprises, Inc.
A maker of long-duration energy storage systems, Eos builds big zinc-based batteries that utilities and industrial customers use to store power on the grid. Founded in 2008, its battery line carries the name Znyth, a mashup of the element symbol for zinc (Zn) and the word "zenith," or highest point. Its batteries are water-based and non-flammable, made from abundant, recyclable materials, and built in the United States.
