    The invention provides a method of making an electrochemical cell. The method comprises loading, into the cathode compartment of the cell an alkali metal aluminium halide molten salt electrolyte having the formula MAlHal4 wherein M is the alkali metal of the separator and Hal is a halide; an alkali metal halide MHal wherein M and Hal are respectively the same alkali metal and halide as in the molten salt electrolyte; aluminium; and an active cathode substance which includes a transition metal T selected from the group conprising Fe, Ni, Co, Cr, Mn and mixtures thereof. An electrochemical cell precursor is thereby made. When the precursor is subjected to charging at a temperature at which the molten salt electrolyte and alkali metal M are molten, aluminium reacts with the alkali metal halide MHal to produce further said molten salt electrolyte and to form said alkali metal M, the alkali metal M passing through the separator into the anode compartment. After all the aluminium has reacted with the alkali metal halide to provide a cell in a discharged state, the active cathode substance is halogenated, with further alkali metal M being produced and passing through the separator into the anode compartment, the proportions of alkali metal halide MHal, molten salt electrolyte and aluminium loaded into the cathode compartment being selected so that when the cell is fully charged and all the available active cathode substances has been halogenated, the proportion of alkali metal ions and aluminium ions in the electrolyte being selected such that the solubility of the active cathode substance in the molten electrolyte is at or near its minimum.

    专利说明:

    The invention relates to electrical engineering and relates to a method for manufacturing a chemical current source.
    The purpose of the invention is to increase the degree of recharging.
    The method is carried out as follows.
    An electrolyte from an alkali metal haloaluminate anode, an alkali metal halide anode, active cathode substance based on transition metal T, selected from the group containing Fe, Nl. Co. Cr, Mp mixtures, and
    aluminum. Moreover, the ratio between the electrolyte and the alkali metal halide is such that, after charging, the molar ratio between aluminum halide and alkali metal is 1: 1, which ensures minimal solubility in the electrolyte of the cathode material. Heated to the melt temperature of the electrolyte and alkali metal anode and charged.
    In this case, the cathode material is halogenated and an alkali metal is formed by the reaction
    2MHaf + + THal2, where M is an alkali metal;
    Hal is a halogen.
    Alkali metal through the separator passes into the anode chamber. Present R-sectional aluminum EPPI-modeystapusch with hectares; juvenide alkali metal anode
    4MNa + A1-3 M + MAIHaU
    In this way, an additional alkali metal and electrolyte are formed.
    Excess alkali metal also passes through a separator. It provides resistance to recharging, since an alkaline metal remains in the anode chamber.
    As a result of the implementation of the proposed method, a chemical current source is produced in a charged state, in which at the operating temperature in the anodic compartment there is a molten alkali metal, and in the cathode - an electronically conducting matrix impregnated with molten electrolyte from an alkali metal haloaluminate dispersed in it is a cathode substance based on a transition metal selected from the group containing Fe, Ni, Co, Cr, Mn and their mixtures. The cathode and anode compartments are separated by a solid conductor of alkali metal ions of the anode, for example, / J-alumina or a molecular sieve with a sorbed alkali metal anode, for example, a zeolite.
    The aluminum introduced into the cathode compartment can be taken in metallic form, in particular in powder form. The cathode active substance is a transition metal, while aluminum can be introduced as an alloy with a transition metal of a cathode substance, in particular, the transition metal can be coated with an alloy with aluminum. Part of aluminum may be replaced by zinc.
    Alkali metal can be loaded into the cathode compartment in metallic form. As a result of its reaction with the molten electrolyte, an alkali metal halide and aluminum are formed. The alkali metal can be placed in the cathode compartment by impregnation of a porous carrier.
    The preparation of the matrix may include sintering the particles, for example powders or fibers of the transition metal, in a reducing atmosphere. Or, conversely, preparation of the matrix may include molding a mixture of particles with an organic binder, pressing from a single unit mixture and cracking the binder by heating the mixture under vacuum at a temperature above 400 ° C, which is sufficient for the binder to pyrolyze. For example, transition metal carbide can be mixed with a small amount
    carbon-forming organic binder, for example, phenol-formaldehyde resin. An electrode is pressed from the resulting mixture, and the resin is cracked in vacuum at a temperature above 600 ° C, which is chosen for pyrolysis of the binder into conductive carbon.
    The incorporation of NaCI and AI into the matrix can be carried out simultaneously with the formation of the matrix, while NaCI and AI in finely divided form are dispersed in the powder material from which the matrix is formed, before the formation of the matrix. NaCI and AI can be incorporated into the matrix by melting the electrolyte and suspending powdered NaCI and AI in finely divided form in the molten electrolyte before the matrix is impregnated with the electrolyte, and then the matrix is impregnated with electrolyte with suspended NaCI and AI. The treatment of the matrix can be carried out by vacuum impregnating it with electrolyte in the molten state.
    It is more preferable to prepare the mixture by mixing powders of NaCl, Al and transition metal or their compounds.
    The cathode active substance can be loaded into the cathode chamber as an intermediate of a transition metal with at least one non-metal from the group consisting of C, SI, B. N and AI.
    The cathode active substance and the alkali metal halide can be mixed in powder form to form a mixture, which is sintered to obtain an electrolyte-permeable matrix, and is impregnated with the molten electrolyte prior to its loading into the cathode chamber. If aluminum is present in a free-flowing form, it may form part of the mixture that is sintering.
    When the transition metal is present in the form of an intermediate, the compound may be a carbide, such as iron, chromium or manganese carbide.
    Alkali metal can be sodium, and halogen - chlorine.
    The aluminum that is first introduced into the cathode compartment must be positioned so that the formed one does not spoil the separator. For example, aluminum in the form of thin sheets is placed at a distance from the separator and electrically connected to the cathode current collector.
    Since the cell undergoes repeated charge-discharge cycles, the excess sodium chloride content that is present in the cathode compartment in the beginning, f) yw always ensure sufficient sodium in the anode compartment to maintain the entire surface of the sodium-coated separator, even when the cell is overcharged .
    Excess alkali metal provides resistance to recharging, since alkali metal remains in the anode chamber.
