1. A cell for testing an electrochemical battery, wherein the cell comprises two electrodes, intended to be in electrical contact with the electrochemical battery to be tested, the cell comprising:
a. a test cell made of non-conductive ceramic, comprising:
i. a cavity intended to receive the electrochemical battery to be tested, the electrochemical battery being intended to be subjected to an electrochemical cycle;
ii. an outlet orifice for gas generated during the electrochemical cycle, the outlet orifice being fluidically connected with the cavity and of a section substantially at right angles to a first axis;
iii. a through opening extending on a second axis (Z), secant with the first axis, including the cavity
b. an application device for applying a temperature and a pressure to the electrochemical battery, comprising the two electrodes, the device being tight to the gases generated by the electrochemical battery during the electrochemical cycle, the electrodes being made of a corrosion-resistant material, the device further comprising a bottom metal part and a top metal part, each comprising a protuberance extending on the second axis (Z) in the through opening and of a form complementing the through opening, each protuberance being terminated by one of the two electrodes, the bottom part and the top part being movable in translation on the second axis (Z) relative to one another, so as to apply the pressure to the electrochemical battery.
