Fluoropolymer membrane for electrochemical devices

Double pole battery comprising three electrochemical cells stacked along a longitudinal axis, each cell consisting of an anode, a cathode and an electrolyte placed between the anode and the cathode, a current collector plate electrically connecting an anode of a cell and a cathode of an adjacent cell, a current collector plate on the anode of a cell located at a first longitudinal end of the stack, a current collector plate on the cathode located at a second longitudinal end of the stack, an electrolyte-proof lateral wall surrounding each cell between each pair of successive collector plates, wherein the lateral walls of two adjacent cells are offset transversely one relative to the other relative to the longitudinal axis, in such a way they are not superposed one on the other.

Multi pole battery with improved interplate leakproofing

This glass-metal penetration is made from glass, a metal pin and a body. The glass is of the TA23 type and the pin is made using solid platinum/iridium (90/10).
