    The present invention relates to a secondary electrochemical cell of aluminum air. Therefore, the invention could be framed in the storage sectorenergy and in particular in the sector of technologies and industry that requireenergy accumulators 10 STATE OF THE TECHNIQUE
    The present invention is based on the phenomenon discovered in the early nineteenth century by Georges Leclanché, who used coal as an active material in the cathode of the Leclanché cell. I note that the oxygen adsorbed on the carbon was reduced thanks to
    15 the catalytic action of manganese oxide. This discovery resulted in research on the use of oxygen as a free and inexhaustible reagent. Here began the development of the fuel cell thanks to Willian R. Grove and his publication "On the Gas Voltaic Battery", and various scientists in metal air batteries.
    20 Metal-air batteries and batteries were already stated as the batteries of the future due to the suppression of the need to store cathode reagents, and the only limitation of the battery is the metal used in the anode. Since then, a large number of scientific publications and related patents have been filed and registered.
    25 to metal-air batteries. Metals like zinc [M. Xu, D.G. Ivey, Z. Xie, W. Qu, Journal of Power Sources 283 (2015) 358-371], classic anode of a large number of primary batteries, magnesium [Y. Gofer, O. Chusid, D. Aurbach, Encyclopedia of Electrochemical Power Sources (2009) 285-301], aluminum [M. Mokhtar, M.Z.M. Talib, E.H. Majlan, S.M. Tasirin, W.M.F.W. Ramli, W.R.W. Daud, J. Sahari, Journal of
    30 Industrial and Engineering Chemistry 32 (2015) 1-20, D.R. Egan, C. Ponce de Leon,
    R.J.J. Wood, R.L. Jones, K.R. Stokes, F.F. Walsh, J. Power Sources 236 (2013) 293310] or lithium [H. Cheng, K. Scott, Rechargeable Lithium Batteries (2015) 41-71] in recent years, have been extensively studied. Many of these investigations are focused on primary or non-rechargeable batteries, among which
    35 developments such as the zinc-air battery or the magnesium-nitrate silver battery have become commercial and established in the market for specific applications.


    As for the rechargeability of these electrochemical pairs, a large number of patents related to zinc or lithium have been filed, but currently none of these developments are commercial, nor are they considered to be industrially produced.
    5 Aluminum-air has been widely studied by various research groups worldwide and a number of companies such as Alupower or Alcan registered a large number of patents for the optimal compositions of aluminum alloys as anodes or electrolyte additives. All these patents were based on the stack of
    10 aluminum-air with aqueous electrolyte.
    An aluminum-air battery or Al-air battery comprises an aluminum anode that reacts with the oxygen in the air and a cathode that is submerged in an aqueous electrolyte. This battery produces electricity (1.5 V when the electrolyte is alkaline) at
    15 from the following semi-reactions [M. Pino, J. Chacón, E. Fatás, P. Ocón, Journal of Power Sources 299 (2015) 195-201]:
    - oxidation half-reaction of the anode is Al + 3OH− → Al (OH) 3 + 3e− [−2.31 V]
    20-cathode reduction semirreaction is O2 + 2H2O + 4e− → 4OH− [+0.40 V]
    the total reaction being 4Al + 3O2 + 6H2O → 4Al (OH) 3 [+2.71 V]
    Aluminum-air batteries are primary cells, that is, not rechargeable. One time
    25 that the aluminum anode is consumed, the battery will stop producing electricity. Rechargeability in aqueous media becomes very complicated because the reduction potential of aluminum is greater than the potential for water decomposition (± 1.2 V). Therefore, by applying a current to reduce the aluminum ions present in the aqueous electrolyte after the discharge of the battery, the water decomposes into O2 and H2, without
    30 to reduce the Al3 + ion to its metallic state.
    The rechargeability of the aluminum cell has been studied extensively and two routes have shown the most satisfactory results: the first is the use of organic solvents with precursor salts for the deposition of aluminum such as chloride
    35 aluminum or aluminum fluoride [S. Licht, R. Tel-Vered, G. Levitin, C. Yarnitzky, Journal of The Electrochemical Society 147 (2000) 496-501]. The main problem of


    These solvents are the high volatility, as well as the high corrosion rate they cause in carbonaceous materials, so the air cathode seems not to work properly. The second and most recent route has been the use of ionic liquids for the electrodeposition of aluminum [O.B. Babushkina, E. Lomako, J.
    5 Wehr, O. Rohr, Molten Salts Chemistry and Technology (2014) 339-349] withVery promising results. The disadvantage of these ionic liquids is their highviscosity at room temperature and influence of the working temperature on yourperformance.
    10 Therefore, it is necessary to develop electrochemical aluminum-air cells that can respond satisfactorily to loading and unloading cycles. DESCRIPTION OF THE INVENTION
    The present invention relates to a secondary aluminum-air electrochemical cell, that is, the present invention relates to a rechargeable or reversible electrochemical cell or battery. The cell comprises aluminum as a negative electrode that faces two positive electrodes that form the cathode. Anode and cathode
    20 are electrically connected by a non-aqueous electrolyte composed of an ionic liquid and an organic solvent. To avoid the short circuit by contact of electrodes, polymeric separation membranes with a pore size that allow the mobility of the Al + 3 ions towards the cathode are used.
    25 The set of elements is wrapped in a microperforated housing to allow oxygen to enter during battery discharge and oxygen output during charging according to the reactions:
    - cathodic discharge semi-reaction or oxygen reduction reaction:
    30 O2 + 2e- → 2O *
    - cathode half-reaction in charge or oxygen formation (in English reaction known as “oxygen evolution reaction”): 35
    2O * - → O2 + 2e


    These micro-perforations are around 1 to 10, preferably 1 to 5 µm, to prevent electrolyte leakage or moisture ingress, but allowing oxygen to enter and leave the electrodes. These perforations have a size
    5 small enough that, thanks to the surface tension of the water, it is not able to enter. In addition, the electrolyte, being composed of large molecules, does not physically escape from the shell.
    In the electrochemical cell of the present invention the following semi-reaction occurs during discharge:
    - at the anode: the oxidation semi-reaction of aluminum giving aluminum ions as a product
    15 (Al + 3) Al + 3e- → Al3 +
    - at the cathode: the oxygen reduction half-reaction resulting in superoxides according to the reaction:
    20 O2 + 2e- → 2O * -
    Resulting the global reaction:Al + O2 → AlO2 *
    25 During the recharge the opposite process occurs, regenerating the original species, the aluminum superoxide is broken to give rise to the reduction of metallic aluminum (Al0) in the anode and the formation of oxygen in the cathodes.
    The Al-air battery of the present invention has a cyclability greater than 200
    30 cycles maintaining a coulombic efficiency of 75%, with an initial cell potential greater than 2 volts during the first charge and discharge cycles, due to the formation of a solid electrolyte interface on the positive electrode consisting of a solid interface of electrolyte absorbed by the gas diffusion layer.
