ROI Calculation Logic

This technology could shorten the development period for new all-solid-state batteries from an estimated 5 years for in-house development to 0.5 years through licensing. Assuming an average annual development cost of $500K (AI est.), the cost reduction from accelerated development is (5.0 years - 0.5 years) × $500K/year = $2.25M (AI est.). Furthermore, avoiding opportunity loss from delayed market entry and accelerating market share acquisition could generate over $1.0M/year (AI est.) in first-mover advantage.

Speed to Market
10× faster than in-house development
This technology has already demonstrated performance at the prototype stage, with established material compositions and operating principles. This allows licensees to significantly reduce the approximately 5 years required for zero-base R&D, potentially starting product development in as little as 0.5 years. The manufacturing process for conductive-material-coated activated carbon and the composite formulation technology are highly compatible with existing battery manufacturing equipment, enabling rapid commercialization without extensive capital investment.
