Annette Valceschini is a Cell Engineer at Mana Battery, Inc., a Broomfield, Colorado-based cleantech startup pioneering high-energy sodium-ion battery technology with a proprietary anode-free cell architecture and fire-extinguishing electrolyte platform.

Annette holds a Bachelor of Science in Chemistry from California State University, Chico, and built deep expertise over nearly a decade spanning quality control, electrode engineering, and battery science roles at Forge Nano and Solid Power.

Her hands-on background in Atomic Layer Deposition coated powders, slurry casting, electrode formulation, and coin cell development gives her rare end-to-end fluency across the battery manufacturing stack.

At Mana Battery, Annette leads benchtop slurry casting, coating, and formulation development for sodium-ion cathodes and anodes, directly advancing the company's breakthrough anode-free cell platform.

Mana Battery recently raised a $10.15M seed round, won Battery Innovation of the Year at The Battery Show North America 2026, and signed joint development agreements with Saft and a global EV leader, positioning its technology for defense, grid, and EV markets.
