# Parts of primary cells, primary batteries and electric accumulators (including separators)

## 1. Scope and Applicability

This PCR applies to the gate-to-gate manufacture of separately supplied, ready-for-assembly parts dedicated to primary cells, primary batteries, or electric accumulators. It provides route-specific foreground rules for microporous polyolefin separators, coated lithium-ion electrodes, and lead-acid grids or plates. A data package shall select only the process route and atomic flows that physically apply to its declared part.

The boundary begins with purchased, specification-controlled materials at the part-manufacturing gate and ends with a conforming part released at the same facility gate. It excludes upstream production of purchased active materials, metals, polymers, chemicals, electricity, fuels, and water; complete-cell or complete-battery assembly; electrolyte filling of complete cells; battery-management electronics; use; transport after the manufacturing gate; and end-of-life treatment. Outbound distribution packaging is outside this reference flow and shall be disclosed if a study adds it.

The confirmed reference product is a battery separator. The process and data rules may guide other covered part families, but a non-separator dataset shall use its own exact approved product flow and shall not reuse the Battery Separator UUID.
