Electrochemical single cell, method for operating a single electrochemical cell and battery of a plurality of electrochemical single cells

摘要

The invention relates to an electrochemical single cell (1) with two pole contacts (7, 8) and an integrated safety device (9) which detects a current flow between the pole contacts (7, 8) when a predeterminable internal cell pressure (P) and / or a predeterminable internal cell temperature is exceeded (T) irreversibly interrupts. According to the invention, a cell electrode (5) is contacted with a connection (10) which is led out as the third pole contact (2) from a cell housing (3) of the individual cell (1). The invention further relates to a battery comprising a plurality of individual electrochemical cells (1). The invention further relates to a method for operating an electrochemical single cell (1).
