A catalytic device includes a hollow body, a piston housed in the hollow body, a catalyst of a gas generation reaction based on bringing a reactive liquid into contact with the catalyst, the catalyst being housed in a catalysis chamber, the piston and the hollow body defining a hermetic compression chamber for containing a compressible fluid, and being mobile relative to one another between a closed position in which the catalysis chamber is tight to the reactive liquid, and an open position for the entry of the reactive liquid into the catalysis chamber. The catalytic device is conformed to switch from the open position to the closed position, respectively from the closed position to the open position, when the compressible fluid is contained in the compression chamber and a force applied to the piston is greater than or equal to, respectively less than, a closure force.

Gas generation device

A semi-automatic method for making a Li-ion electrochemical accumulator according to which a continuous electrolytic separator strip is automatically wound on two-sided electrodes manually and alternately stacked according to their polarity. By the method, it is not necessary to assemble or manually cut out each electrolytic separator inserted between two adjacent electrodes in the stack and of opposite polarity.
