The present disclosure relates to a device for measuring the amount of oxygen present in a gas to be analyze. The device includes at least one member for measuring the amount of oxygen, a first inlet in communication with the measuring member for the supply of gas to be analyzed, and an outlet for the discharge of said analyzed gas. The device also includes a second inlet intended to communicate with the measuring member, allowing said device to be supplied selectively with a calibration gas having a known amount of oxygen, such that the measurement of the amount of oxygen present in the calibration gas makes it possible to determine a potential drift of the measurement of said measuring member relative to the actual known amount of oxygen present in the calibration gas.

The invention concerns a new flexible or rigid packaging for an electrochemical accumulator (A). It is made from at least one polyaryletherketone (PAEK) sheet, notably a polyetheretherketone (PEEK&#x2122;) sheet. According to a preferred embodiment, a polyaryletherketone (PAEK) sheet () incorporates within it at least one metal stud () constituting one of the poles of the accumulator. The main application sought is the packaging of lithium-ion accumulators.

Disclosed is a liquid electrolyte for a lithium accumulator and the use thereof in a lithium accumulator at low temperature. The liquid electrolyte includes at least one lithium salt dissolved in a mixture of non-aqueous organic solvents. The mixture of organic solvents is formed by propylene carbonate (PC), &#x3b3;-butyrolactone (GBL) and ethyl methyl carbonate (EMC). The mixture of organic solvents preferably contains between: 0.5% and 33% in volume of propylene carbonate, 0.5% and 33% in volume of &#x3b3;-butyrolactone and, 0.5% and 99% in volume of ethyl methyl carbonate, the sum of the respective volume percentages of propylene carbonate, &#x3b3;-butyrolactone, and ethyl methyl carbonate in the mixture being equal to 100%.
