Additionally, the cell comprises a positive electrode that is disposed in a positive electrolyte solution. In order to separate the negative electrode and the negative electrolyte solution from the positive electrolyte solution, the cell includes a sodium ion conductive electrolyte membrane. Because the cell's negative electrode is in a solid state as the cell functions, the cell may operate at room temperature. Additionally, where the negative electrolyte solution contains the ionic liquid, the ionic liquid may impede dendrite formation on the surface of the negative electrode as the cell is recharged and sodium ions are reduced onto the negative electrode.

It is obtained by a process consisting in preparing a carbonaceous precursor gel by bringing carbon, ?-V2O5 and a Li precursor into contact in amounts such that the ratio of the [V2O5]/[Li] concentrations is between 1.15 and 1.5 and that the (carbon)/(carbon+V2O5+Li precursor) ratio by weight is from 10 to 15 and in subjecting the gel to a heat treatment comprising a 1st stage at 80° C.-150° C. for 3-12 h and a 2nd stage between 300° C. and 350° C. for 10 min to 1 hour, under an nitrogen or argon atmosphere. Applications: positive electrode active material.

  • Publication number: 20080261098
    Abstract: A method for making a proton-conducting membrane is described. The method includes the steps of combining a protonated, layered inorganic material with a proton-conducting organic polymer in a liquid medium; exfoliating the layered inorganic material, so that individual layers of the inorganic material are suspended in the liquid medium and spaced from each other; and the polymer is absorbed onto the surface of the individual layers. In this manner, a polymer-inorganic composite is formed. The liquid can then be removed, to recover the resulting membrane. Related electrolysis and fuel cell devices are also described, which incorporate the proton-conducting membrane.

  • Patent number: 7377948
    Abstract: Methods of the present invention are provided for forming a plurality of electrochemical cell layers, each cell layer generally including a pair of electrodes and a separator electrically insulating the pair of electrodes. Cells of a desired size are formed by slicing the laminar sheet through both opposing major surfaces. In certain embodiments, individual cells are defined by fill regions, filled with removable substances. Thus, when the cells are sliced, individual cells and in certain embodiments current collectors or conductors are exposed with minimal or no further processing. In other embodiments, fluid access channels or porous layers are filled with removable substances. Thus, when the cells are sliced, structural support is provided for the intended void regions.
