Lithium-air battery with cathode separated from free lithium ion

A lithium-air electrochemical cell is provided. The battery comprises: an anode compartment; a cathode compartment; and a lithium ion conductive membrane separating the anode compartment from the cathode compartment. The anode compartment comprises an anode having lithium or a lithium alloy as active metal and a lithium ion electrolyte, while the cathode compartment comprises an air electrode and an ionic liquid capable of supporting the reduction of oxygen. A lithium ion concentration in the cathode compartment is such that the lithium ion concentration is greatest at the lithium ion selective membrane and lowest at the cathode.

Ionic membrane electrolytic bath

An ionic membrane electrolytic bath, comprising an anode compartment and a cathode compartment, wherein a gas-liquid separation chamber is provided in the anode compartment and/or the cathode compartment; the gas-liquid separation chamber is locally built in the anode compartment and/or the cathode compartment; a first part of the gas-liquid separation chamber for accommodating liquid is provided inside the anode compartment and/or the cathode compartment; and a second part of the gas-liquid separation chamber for accommodating gas is provided outside the anode compartment and/or the cathode compartment. In the ionic membrane electrolytic bath, the gas-liquid separation chamber is locally built in the anode compartment and/or the cathode compartment, and a gas-liquid channel is lifted to an upper part of the gas-liquid separation chamber, thereby fully using the area of an ion exchange membrane and cathode and anode power grids, which is equivalent to increasing electrolytic areas of cathode and anode electrodes, so that the yield of the ionic membrane electrolytic bath is higher. On the other hand, an electrolysis product can be rapidly discharged.

Method for regenerating the capacity of an electrochemical lithium battery, and associated battery housing and battery

The invention relates to a method for regenerating the capacity of an electrochemical lithium battery, comprising the following steps: a) evaluating the quantity of lithium ions; b) when the evaluated lithium ion quantity is less than or equal to a threshold value, applying an electric current between the cathode or the anode and the container such as to cause the delithiation of the casing. The casing is also arranged to house an element (7) providing both electric insulation and ionic conduction between the anode and cathode electrodes of the electrochemical cell and the casing, said casing comprising at least one lithium ion storage zone (61).
