Inventory is a hypothesis; handling, waste, protection, calibration, quantities, losses and suitability are not completely identified.
Making outline
- Mix selected LCO/carbon/PVDF-NMP slurry, coat aluminum foil, dry, calendar and slit electrode
- Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.
What remains unresolved
- Candidate method, complete inventory, caller demands and physical compatibility require research and review.
- Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
- Loading/porosity/thickness/pinhole/adhesion/areal capacity, drying residuals and edge-burr controls unresolved.
