  • Patent number: 6679926
    Abstract: A lithium secondary battery including an anode and cathode containing an active material capable of incorporating and releasing lithium ions, wherein the cathode is a porous sintered material made of a lithium-transition metal oxide, the porosity of the sintered material is 15 to 60%, and the electrical conductivity is not less than 0.1 mS/cm. Since the sintered material is sufficiently sintered so that the electrical conductivity may be more than 0.1 mS/cm, the bonding power of the primary particles of the sintered material is strong, and therefore the primary particles do not come off and the electrodes do not collapse even if the sintered material expands or shrinks because of the charge/discharge. Since the mechanical strength is great, the cathode can have a larger area. The electrolyte penetrates well into the sintered material because of its 15 to 60% porosity, and consequently the internal electrical resissitivity is low.

  • Patent number: 6413672
    Abstract: The present invention relates to a lithium secondary battery with a cathode and an anode, each electrode containing an active material capable of incorporating and releasing lithium ions. The anode includes a sintered material which contains 50 to 99 % by weight of silicon and 1 to 50% by weight of carbon material, and has an electrical conductivity not less than 1 S/cm. By employing the anode including the sintered material containing silicon as the anode active material and carbon material, an increased packing density of the active material and an increased capacity per volume can be obtained. Furthermore, the anode conductivity of not less than 1S/cm can provide a high capacity and improved cycle property.

  • Patent number: 6287728
    Abstract: By using a porous material formed by calcining an active material as an electrode of a non-aqueous solvent secondary battery, the volume of a dead space in the electrode contained in a container of the constituted battery is reduced, thereby to increase an electric capacity per unit volume. By using the porous material as the electrode material, rather a powder material, the active material is sufficiently brought into contact with an electrolyte solution, electrically. Furthermore, the amount of a metal foil as a current collecting material and a conductive material are reduced or use of them is made unnecessary, and an electric capacity per unit weight is increased in comparison with the prior art. When the porous sintered material has a plate-like shape, the thickness is from 100 &mgr;m to 2 mm. The porous sintered material contains pores of an average diameter of 0.

  • Patent number: 5537344
    Abstract: A convolution of input data S.sub.0 and a Gabor function G.sub..alpha.,.omega. is implemented by a processing unit (20) to obtain a wavelet coefficient T.sub.g (2.sup.0,b) of a 0th stage. The input data S.sub.0 is applied to a low-pass filter (30) and is subjected to Gaussian-type filtering so as to be converted into input data S.sub.1 for a 1st stage. The frequency of the high-frequency components of this input data is halved by this filtering. A convolution of this input data S.sub.1 and a Gabor function G.sub..alpha. /3,2.omega./3 is implemented by a processing unit (21) to obtain a wavelet coefficient T.sub.g (2.sup.1,b) of the 1st stage. In the convolution of the 1st stage, the sampling interval is twice that of the 0th stage. Thenceforth, and in similar fashion, the sampling interval in processing operations of subsequent stages is doubled from one stage to the next. As a result, there is no increase in the amount of processing in each stage and a coefficient T.sub.g (2.sup.
