Title: Positive electrode for primary cells
Inventor: GROHS ERHARD DIPL-ING
IPC: H01M4/10
Filed: 1969-09-10
Abstract: The depolarising mass is retained in position on the electrode and forced into initmate contact with it by the hoop stress of a jacket around it which is pervious to the electrolyte.
