Advanced Battery Concepts
Advanced Battery Concepts is a Clare, Michigan battery maker that did something contrarian: instead of chasing lithium, it went back to lead-acid and reinvented it. Its patented GreenSeal bipolar architecture cuts lead content while boosting cycle life, and the company has licensed the design to global battery giants like Clarios, EnerSys, Exide, Crown and Trojan. With its EverGreenSeal line and BatteryBarn utility systems, ABC builds non-flammable, fully recyclable, domestically manufactured energy storage for critical infrastructure and the grid.
Element Energy
Element Energy is a Menlo Park battery management company that uses semiconductor-grade hardware, software, and cell-level controls to extend battery life, prevent fires, and give retired EV batteries a second career on the grid.
