Company Overview

EnPower Inc. is an American battery manufacturer specializing in high-performance lithium-ion technology. Established with a mission to advance electric mobility adoption, the Indianapolis, Indiana-based company operates a 92,000-square-foot manufacturing facility and has earned awards including the 2023 Best of Indianapolis Award and recognition as a leading tech startup.

Battery Technology

EnPower’s patented multilayer electrode design enables strategic porosity and tortuosity for enhanced ion transport, delivering full charges in 16-18 minutes with over 80% capacity retention after 500 cycles. Manufacturing integrates LFP and NMC chemistries; 35 Ah pouch cells use NMC 811 cathodes paired with multilayer graphite anodes for three times faster charging and 70% more power compared to standard lithium-ion cells.

Products

EnPower operates a facility in Indianapolis, Indiana, where it manufactures advanced lithium-ion pouch cells specifically for customer qualification and scale-up. The plant’s initial annual production capacity is 800 megawatt-hours (MWh), with plans to quickly expand beyond 1 gigawatt-hour (GWh) as demand increases. EnPower’s line includes the IP1 (5Ah, 240 Wh/kg) and IP1S (9Ah, 272 Wh/kg) lithium-ion pouch cells, along with toll coated electrodes, all leveraging their patented multilayer electrode architecture for advanced energy and power performance, especially where U.S.-based manufacturing is required.

Recent Projects

In 2024, EnPower advanced production capabilities with planned delivery of LFP and NMC battery cell samples and upgraded its Indianapolis facility with enhanced automation and manufacturing equipment to strengthen the domestic battery supply chain and meet growing demand for fast-charging energy storage solutions.

Investors

Secured $2.9M in funding from the U.S. Department of Energy (2023) and the OwlSpark accelerator program; ongoing funding supports R&D and manufacturing expansion.
