    Abstract: An initial charging operation is carried out by a charging step composed of two- stages or more to improve an initial charging and discharging efficiency, reduce the charge of wasteful materials and improve a high capacity and a high cyclic characteristic without deteriorating various kinds of battery properties. In order to realize the improvements, a nonaqueous solvent which is decomposed under a potential higher than the reduction and decomposition potential of a main solvent is included in electrolyte. This charging method is a method for achieving the addition effect of such a nonaqueous solvent as much as possible. As a specific means , the electrolyte to which vinylene carbonate is added is employed and a constant- current and constant-voltage charge under about 3.2 V is carried out for 1 to 2 hour s before a battery is completely charged. Thus, a good coat can be formed on the surface of an anode while suppressing the quantity of electricity required for forming the coat.

    Abstract: A thin type cell having superior air-tightness and mechanical strength. The thin type cell is made up of a cathode 1, an anode 2 and an electrolyte 3, sheathed within a moisture-proofing multi-layered film 4 formed by a high molecular film and a metal foil. A pair of electrode terminals 5, 6 interconnecting electrodes and external terminals are formed of a netted or porous electrically conductive member. By using the netted or porous electrically conductive materials as the electrode terminals 5, 6, the electrode terminals 5, 6 can be firmly bonded to the moisture-proofing multi-layered film 4. Moreover, by increasing the thickness of high molecular film layer at the sealing portion X passed through by the electrode terminals 5, 6, shorting can be prevented from occurring.

    Abstract: A cell having an excellent discharge load characteristic and an excellent lo w- temperature discharge characteristic. The cell has a coiled electrode elemen t in which band-shaped positive and negative electrodes and a separator (23) impregnated with an electrolyte and interposed between them are coiled. The separator (23) includes a porous film (23a) such that the mean pore diameter is 0.15 ~m or less, and the mean ratio of the largest diameter (DL) of the pores to the shortest diameter (DS) ranges from 0.4 to 1.0. As a result the pores (23b) are prevented from being plugged. The electrolyte permeability, ionic permeability, and electrolyte retainability of the separator (23) are improved. Consequently, the cell can have excellent discharge load characteristic and low-temperature discharge characteristic.

    Abstract: A solid electrolyte cell in which oxidative decomposition of electrolyte components is suppressed to maintain the superior cell performance. The solid electrolyte includes a negative electrode 9 having a negative electrode current collector 7 and a negative electrode active material 8, a positive electrode 12 having a positive electrode current collector 10 and a positive electrode active material 11 and a solid electrolyte 13 arranged between the negative electrode 9 and the positive electrode 12 and which is comprised of an electrolyte salt dispersed in a matrix polymer. A diene compound is contained in at least one of the positive electrode 12 and the solid electrolyte 13.

    Abstract: A THIN TYPE CELL HAVING SUPERIOR AIR- TIGHTNESS AND MECHANICAL STRENGTH. THE THIN TYPE CELL IS MADE UP OF A CATHODE 1, AN ANODE 2 AND AN ELECTROLYTE 3, SHEATED WITHIN A MOISTURE - PROOFING MULTI-LAYERED FILM 4 FORMED BY A HIGH MOLECULAR FILM AND A METAL FOIL. A PAIR OF ELECTRODE TERMINALS 5, 6 INTERCONNECTING ELECTRODES AND EXTERNAL TERMINALS ARE FORMED OF A NETTED OR POROUS ELECTRICALLY CONDUCTIVE MEMBER. BY USING THE NETTED OR POROUS ELECTRICALLY CONDUCTIVE MATERIALS AS THE ELECTRODE TERMINALS 5, 6, THE ELECTRODE TERMINALS 5, 6 CAN BE FIRMLY BONDED TO THE MOISTURE-PROOFING MULTI- LAYERED FILM 4. MOREOVER, BY INCREASING THE THICKNESS OF HIGH MOLECULAR FILM LAYER AT THE SEALING PORTION X PASSED THROUGH BY THE ELECTRODE TERMINALS 5, 6, SHORTING CAN BE PREVENTED FROM OCCURRING. (FIG. 2)
