    Abstract: A solid-electrolyte secondary battery is provided which comprises a positive electrode, negative electrode and a solid electrolyte provided between the electrodes. The solid electrolyte contains as a matrix polymer a vinylidene fluoride/hexafluoropropylene block copolymer. The film of the block copolymer has a high mechanical toughness and solvent retaining capability. Use of this block copolymer film as the matrix polymer of the solid electrolyte greatly improves the adhesive strength, load characteristic and low-temperature performance. In the block copolymer, the proportion of hexafluoropropylene should preferably 3 to 7.5 % by weight. The molecular weight should preferably be of over 550,000. A block copolymer of over 300,000 in Mw and under 550,000 in Mw may be used in combination with the above one.

    Abstract: A solid electrolytic secondary battery comprising a positive electrode, a negative electrode and a solid electrolyte interposed between the electrodes, wherein the solid electrolyte contains, as matrix polymer, fluorine polymer having a weight-average molecular weight (Mw) of 550,000 or larger, which polymer delivering an excellent adhesiveness to the active material layers of the positive and negative electrodes, thereby enabling a polymer sold electrolyte or a gel electrolyte to be bonded to electrode active material layers with a sufficient adhesive strength. In view of a paint viscosity, fluorine polymer having a weight-average molecular weight (Mw) of not smaller than 300,000 and less than 550,000 may be jointly used.

    Abstract: A battery capacity calculating method can very accurately calculate a residual capacity of a secondary battery especially in the last stage of discharging independently of environmental conditions such as a temperature or a deteriorated state. A battery capacity calculating apparatus (10) is equipped with a voltage measuring circuit (11) which measures the terminal voltage (Vmea) of a battery (1) at the time of discharging, a current measuring circuit (12) which measures the current value (I) of the battery (1) at the time of discharging, and a control circuit (13) which calculates a residual capacity and/or residual power. The operation unit (15) in the control circuit(13) calculates a discharged capacity (Qmea) and an apparent discharged capacity (Qocv) based on a terminal voltage (Vmea) and a current value (I) measured by the voltage measuring circuit (11) and the current measuring circuit (12), respectively, estimates a discharge curve (Cpre) in the future including the last stage of discharging based on a capacity shift ( DELTA Q) being the difference between the discharged capacity (Qmea) and the apparent discharged capacity (Qocv) during discharging, and calculates the residual capacity and/or the residual power of the battery (1) based on the estimated discharge curve (Cpre).

    Abstract: A nonaqueous-electrolyte secondary battery (1) is disclosed which is capable of maintaining satisfactory adhesiveness of leads (3,4) of terminals of electrodes in heat-welded portions of a case (2) of the nonaqueous-electrolyte secondary battery without deterioration of the moistureproofing characteristics. A battery element is accommodated in a case constituted by laminated films such that the battery element is encapsulated by heat welding. Leads of terminals of electrodes electrically conducted with the electrodes which constitute the battery element are exposed to the outside portion of the nonaqueous-electrolyte secondary battery through heat-welded portions. Portions of the leads of the terminals of the electrodes corresponding to the heat-welded portions are coated with an olefine adhesive layer containing a titanate coupling material and a coating layer made of resin which is the same as resin which forms the innermost layer of each of the laminated films.
