Enerdel was an American company that developed energy storage technology based on building compact lithium-ion-powered batteries for the transportation, utility grid and industrial electronics markets.
The company was headquartered in Greenfield, Indianapolis, Indiana, and had manufacturing locations in the United States and Korea. Enerdel also develops commercial fuel cell products and nanotechnology-based materials.
The company had been listed on the Nasdaq through it parent holding company Ener1 until it filed for bankruptcy protection in 2012. The company was acquired by a private investor, Paul Herbert, through his company PLH Energy in 2022. Herbert had been a Director of EnerDel for a number of years prior to the acquisition and had been part of refocusing the business onto bespoke energy storage.
