EnPower Inc. is an American battery manufacturer specializing in high-performance lithium-ion technology. Established with a clear mission to advance electric mobility adoption, the company has developed innovative multilayer electrode technology that significantly improves battery charging speeds while maintaining long-term performance. Based in Indianapolis, Indiana, EnPower operates a 92,000-square-foot manufacturing facility equipped with state-of-the-art production capabilities. The company’s achievements in fast-charging battery development have earned multiple awards, including the 2023 Best of Indianapolis Award and recognition as a leading tech startup.
Battery Technology
EnPower’s primary innovation centers on its patented multilayer electrode design, which addresses traditional limitations in lithium-ion batteries. This technology enables strategic porosity and tortuosity for enhanced ion transport, resulting in superior charging capabilities without sacrificing energy density. The company’s batteries achieve full charges in 16-18 minutes while maintaining over 80% capacity after 500 cycles – significantly outperforming conventional designs.
The manufacturing process incorporates both LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt) chemistries, offering versatility for different applications. EnPower’s 35 Ah pouch cells feature NMC 811 cathodes paired with multilayer graphite anodes, delivering three times faster charging and 70% more power compared to standard lithium-ion cells. These specifications make the technology particularly suitable for automotive, marine, and military applications where rapid charging and sustained performance are essential.
Recent Projects
In 2024, EnPower is advancing its production capabilities with planned delivery of LFP and NMC battery cell samples scheduled for May. The company continues to upgrade its Indianapolis facility with enhanced automation and manufacturing equipment. These improvements support EnPower’s commitment to strengthening the domestic battery supply chain and meeting increasing demand for fast-charging energy storage solutions.
Investors
EnPower has secured $2.85 million in funding through various rounds. Notable investors include the U.S. Department of Energy, which provided grant funding in July 2023, and OwlSpark, a Texas-based accelerator program. The company maintains active funding initiatives to support ongoing research, development, and manufacturing expansion.
