Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

Mix selected graphite/carbon/PVDF-NMP slurry, coat copper 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.
