ROI Calculation Logic

Assuming annual electrode replacement costs (materials, labor, downtime) of ~$3.5M (AI est.) per electrolytic refining plant. This technology extends electrode lifespan by 2x, halving replacement frequency. This could lead to an estimated ~50% reduction, or ~$1.5M (AI est.) in annual costs. This estimate excludes revenue increases from enhanced production capacity.

Speed to Market
8× faster than in-house development
This technology's core — the MoSi2-based electrode and surface oxide film formation — is thoroughly detailed in the patent. Fundamental materials research is presumed complete, allowing licensees to significantly shorten material selection, process development, and characterization compared to in-house development. This could reduce time-to-market by approximately 3.5 years, with high applicability to existing electrolytic refining processes for rapid adoption and validation.
