Title

Titles differ between systems:

CPC: Spacing elements inside cells other than separators, membranes or diaphragms (for preventing incorrect contact inside or outside batteries H01M50/584); Manufacturing processes thereof

Full Title

Full titles differ between systems:

IPC:

Constructional details or processes of manufacture of the non-active parts of electrochemical cells other than fuel cells, e.g. hybrid cells > Separators; Membranes; Diaphragms; Spacing elements inside cells > Spacing elements inside cells other than separators, membranes or diaphragms; Manufacturing processes thereof

CPC:

Constructional details or processes of manufacture of the non-active parts of electrochemical cells other than fuel cells, e.g. hybrid cells > Separators; Membranes; Diaphragms; Spacing elements inside cells > Spacing elements inside cells other than separators, membranes or diaphragms (for preventing incorrect contact inside or outside batteries H01M50/584); Manufacturing processes thereof

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2021.
