Coulomb Technology, based in Knoxville, Tennessee, develops advanced zinc-manganese dioxide (Zn-MnO2) rechargeable batteries. Founded in 2022, the company focuses on safe, affordable, and sustainable energy storage and e-mobility solutions. Operating from Meridian, Idaho, and sponsored by Innovation Crossroads at Oak Ridge National Laboratory, Coulomb Technology aims to innovate the battery market. Zinc-ion batteries serve as cost-effective alternatives to lithium-ion, with applications in residential energy storage, industrial grid systems, and electric vehicles such as e-bikes and golf carts.

Battery Technology

Coulomb Technology utilizes zinc and manganese dioxide for rechargeable Zn-MnO2 batteries, offering advantages over lithium-ion and lead-acid options. Batteries meet high safety standards, with no fire hazards or toxic materials. They operate efficiently at -20°C to 60°C, suitable for diverse conditions. With low self-discharge rates, they ensure reliable performance. Zinc batteries use earth-abundant materials, reducing environmental impact and lowering production costs to half that of lithium-ion systems. Coulomb Technology’s long-term cost goal is $25/kWh, promoting zinc batteries as reliable, sustainable solutions for energy storage and e-mobility.

Recent Projects

Coulomb Technology has advanced zinc-ion battery technology by joining the 2024 Innovation Crossroads cohort at Oak Ridge National Laboratory. Recent milestones achieved include improved energy density and safety. Plans are in place to produce 5Ah pouch cells by mid-2025, expanding use in residential energy storage and e-mobility. Collaboration with Argonne National Laboratory and funding from the New Jersey Commission on Science, Innovation and Technology highlight a commitment to innovation.

Investors

Coulomb Technology benefits from strategic funding and partnerships with key institutions, including Innovation Crossroads at Oak Ridge National Laboratory and Argonne National Laboratory’s Cradle to Commerce program. Funding from the New Jersey Commission on Science, Innovation and Technology supports the development of zinc-ion battery technology.
