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.

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 fluorocarbon polymer of 550,000 in weight-average molecular weight (Mw). The fluorocarbon polymer having a weight-average molecular weight of more than 550,000 shows an excellent adhesion to the active material layers of the positive and negative layers. Therefore, the high polymer solid (or gel) electrolyte adheres to the active material layers of the electrodes with a sufficient adhesive strength. For the coating viscosity, a fluorocarbon polymer having a weight-average molecular weight (Mw) over 300,000 and under 550,000 is used.

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 nonaqueous electrolyte battery is disclosed which has an improved volume energy density and satisfactory impact resistance, a heat radiating characteristic and producibility. A battery element is accommodated in a casing constituted by a laminate film so as to be sealed by welding. Electrode-terminal leads electrically conducted to electrodes which constitute the battery element are sandwiched by welded portions so as to be exposed to the outside portion of the casing. A control circuit of the battery is mounted on a welded portion of the casing. Since the control circuit of the battery is mounted on the welded portion of the casing, the space in the battery in which the battery element is not present can effectively be used. Therefore, the volume efficiency can considerably be improved.
