Custom Prototyping & Laboratory Fabrication Services
Atomfair provides precision, research-grade contract manufacturing, custom prototyping, and laboratory equipment modification for university laboratories, national institutes, and industrial battery/materials engineering centers. We bridge the gap between benchtop synthesis and reproducible validation across six primary tracks: Electrode Coating, Dry Pouch Cells, Semiconductor Substrates, Milling Media & Jars, In-Situ Test Fixtures, and Controlled Atmosphere Storage.
All contract fabrication supports both Full-Turnkey (standard battery-grade materials supplied by Atomfair) and Consignment/Toll Processing (utilizing customer proprietary powders and functional substrates). Mutual NDAs are executed upon request prior to drawing or recipe disclosure.
Custom Battery Electrode Coating
Precision contract coating supporting continuous/intermittent wet slot-die coating and solvent-free dry PTFE calendering for Li-ion, Na-ion, and solid-state electrodes.

- Substrates: Al, Cu, carbon-coated foils, Ni foam, and stainless steel meshes.
- Quality Control: Tare-deducted actual areal density & Karl Fischer residual moisture CoA.
Custom Dry Pouch Cell Prototyping
