About the company
Edward Buiel Consulting LLC, operating under the business name Coulometrics, is a for-profit limited liability company and sole proprietorship based in Chattanooga, Tennessee, that specializes in the design, fabrication, and testing of advanced lithium-ion battery cells and components. The company has been registered in SAM.gov since January 2011 and maintains an active federal contracting presence through its work with the National Aeronautics and Space Administration. Coulometrics focuses on developing innovative energy storage solutions that enhance the safety and performance of lithium-ion battery technologies for aerospace and scientific research applications, with particular expertise in mitigating thermal runaway risks in high-energy cells used in space missions.
Since 2021, Coulometrics has received eight federal contract awards from NASA's Shared Services Center, totaling over $577,000 in cumulative value, all issued as firm fixed-price purchase orders with no set-aside designations. The company's work has encompassed the design and fabrication of specialized lithium-ion cells in multiple formats, including 18650 and 21700 cell types, with advanced features such as plastic current collectors and cellulose separators specifically engineered to tolerate internal short circuits caused by nail penetration. Notable deliverables include the production of 4680 lithium-ion battery cells with specialized specifications exceeding 265 Wh/kg specific energy, development of robust separators and plastic current collectors for 21700 cells designed to withstand nail penetration testing at 100 percent state of charge, and fabrication of high-energy cell designs meeting rigorous dimensional tolerances. Contracts have consistently been awarded on a sole-source basis under Federal Acquisition Regulation Parts 12 and 13, reflecting NASA's recognition of Coulometrics' unique technical capabilities and the significant competitive disadvantage that would result from attempting to develop comparable capabilities internally or through alternative sources. All performance work has been conducted at the company's Chattanooga facility or at NASA Johnson Space Center, with contract completion dates ranging from 2021 through December 2025.
