EnPower
EnPower is a high-performance battery company specializing in engineering-based innovations that enhance lithium-ion technology, focusing on fast charging and long cycle life.
Company Overview
EnPower is a high-performance battery company that commercializes engineering-based innovations to unlock the full potential of lithium-ion technology. Their core innovation lies in multilayer electrodes designed with strategic porosity and tortuosity to facilitate rapid ion transport through the thickness of electrodes. This technology positions EnPower as a leader in enabling fast charging without harmful cell degradation, making their solutions ideal for various battery applications.
Advanced Battery Technology
EnPower's technology advantage is based on its patented multilayer electrodes, addressing the trade-offs between energy and power in lithium-ion batteries. These multilayer anodes retain over 80% capacity over 500 cycles, compared to only 30 cycles for conventional anodes. The technology is chemistry agnostic, meaning it can improve various anode or cathode materials by optimizing electrode architecture. This enables EnPower to develop innovative NMC (Nickel Manganese Cobalt) and LFP (Lithium Iron Phosphate) battery cell samples tailored to meet diverse customer requirements.
Manufacturing and Production Facility
EnPower operates a 92,000 sq. ft. facility in Indianapolis, IN, capable of producing over 1 GWh of lithium-ion cells annually. The facility is equipped with two coating lines producing over 4 million square meters of electrodes annually, and four pouch cell assembly lines. This large-scale operation supports comprehensive cell testing, production scaling, and sales agreement fulfillment. The company's commitment is marked by the purchase of this facility in 2022, which accelerated their market entry and expanded their production capabilities.
Research and Development
EnPower’s research and development focus allows for rapid innovation and prototyping in 3-7Ah pouch cells. The multilayer electrode architecture solves key trade-offs, offering superior fast charge cycle life, reduced DC internal resistance (DCIR), and improved discharge performance. This R&D capability ensures that EnPower can continuously improve its battery technology to meet evolving market needs, maintaining a competitive edge in the industry.
Awards and Recognition
EnPower has earned several prestigious awards, reflecting its innovation and impact in the battery industry. These accolades include the 2023 Best of Indianapolis Award, 2022 Best Tech Startups, and 2021 Innovator of the Year - Startup. Such recognition underscores EnPower's commitment to advancing battery technology and its significant role in strengthening the U.S. battery supply chain.
