摘要： PURPOSE:To heighten the density of energy and lengthen life of rechargeability, by providing an active material made of anions in the main and contained in an electrolyte to be transferred between both electrodes. CONSTITUTION:A secondary cell comprises a positive and a negative electrodes and an electrolyte. The positive electrode is made of an electroconductive high- molecular substance. The negative electrode is made of a metal. In the charging of the cell, anions are released into the electrolyte from a metal salt produced on the negative electrode as a result of the combination of the metal, and the anions are taken from the electrolyte into the electroconductive high-molecular substance on the positive electrode. In the discharge of the cell, the anions taken into the electroconductive high-molecular substance are released into the electrolyte on the positive electrode to produce the metal and the salt. Since not a metal dissolving/educing reaction on the negative electrode but the transfer of the anions and the reaction with the metal are utilized, the metal for the negative electrode needs to be such that the solubility of the salt made of the metal and the anions is low. The electrolyte is a saturated one in which a salt of a metal of higher ionizability than that for the negative electrode is dissolved.

摘要： PURPOSE:To achieve a high density of electrical current, by previously subjecting a high-molecular electrode to doping and anti-doping with ions of large radium in a different electrolyte solution. CONSTITUTION:A battery comprises a positive electrode 1, a negative electrode 2 and an electrolyte 3. A nonwoven fabric of polypropylene or the like is sandwiched between the electrodes 1, 2 to prevent a short circuit. The nonwoven fabric is impregnated with the electrolyte 3. The high-molecular electrodes having a conjugate double bond in the main chain is previously subjected to doping and anti-doping with ions of large radius to provide the electrode with internal voids through which ions can pass. The battery is then charged and discharged with ions of small radius. Since the ion diffusion voids are large, the speed of ion diffusion is increased to greatly enhance the density of electrical current in the charging and discharge of the battery.

摘要： PURPOSE:To reduce the amount of an electrolytic solution so as to make a secondary battery light and compact by using the electrolytic solution that contains a part of the electrolyte not in a dissolved state in all processes of charge and discharge. CONSTITUTION:In a secondary battery based on doping or intercalation mechanism, an electrolytic solution is formed so as to contain a part of the electrolyte not in a dissolved state in all processes of charge and discharge. For example, the electrolytic solution is formed in which propylene carbonate and such are used as the solvent and ammonium tetraethyl perchlorate or lithium perchlorate is used as the electrolyte. When the electrolyte of a battery in the charge completion state is most consumed, the electrolytic solution contains solid phases and the amount of non-dissolution (the amount of deposition) is set to within 50%, desirably within 20% of the entire electrolyte. Since the amount of solvent can be reduced in this battery, energy density can be improved.

摘要： PURPOSE:To increase coulomb efficiency in the initial stage by applying reduction treatment to a high molecular compound having conjugated double bond and using it as electrode. CONSTITUTION:Reduction treatment is applied to a high molecular compound having conjugated double bond, and this compound is used as electrode. For example, polyacetylene is punched in a disc, and the disc is immersed in propylene carbonate solution of (C2H5)4NBF4 and potential of -0.5V to an Ag-AgCl reference electrode is applied to the disc of working electrod to electrochemically reduce it. This electrochemically reduced polyacetylene is assembled in a battery. By this treatment, oxygen adorbed on polyacetylene, which decreases coulomb efficiency, is removed. Therefore, coulomb efficiency in the initial stage of charge-discharge cycle is increased.

摘要： PURPOSE:To obtain a secondary battery having high coulomb efficiency and low self-discharge rate by applying heat-treatment in a vacuum to an electrode comprising a molecular compound having conjugated double bond in its principal chain. CONSTITUTION:Electrode using a high molecular compound having conjugated double bond in its principal chain is heated in a vacuum before use. For example, by heating in a vacuum (10 mm.Hg or less), acetylene monomer, moisture or oxygen adsorbed on polyacetylene is removed to make clean the surface of the polyacetylene. Temperature of vacuum heat-treatment is preferable to set below the isomerization temperature (145 deg.C) of polyacetylene, and usually to set at 100 deg.C or less. The high degree of vacuum is preferable but the vacuum of 10 - 10 mm.Hg is actually used. By this treatment, a polymer secondary battery having low self-discharge rate and high coulomb efficiency is obtained.

摘要： PURPOSE:To realize a good charge-and-discharge characteristic by fixing conductive sheets located at the ends of a stacked body to an exterior metallic sheets by means of a conductive adhesive. CONSTITUTION:A conductive sheet 11 and an exterior metallic sheet 8 are fixed together by interposing a conductive adhesive between them. For example, in a battery constituted by stacking A, B, C and D cells, conductive sheets (A-1 and D-2) located at both ends are fixed to the inner surface of an exterior aluminum foil 18 by thinly applying a conductive adhesive to the conductive sheets. As a result, battery resistance decreases and coulomb efficiency increases. Moreover it is possible to make the battery thin.
