  • Patent number: 10693138
    Abstract: A cathode material is provided which comprises secondary particles of cathode active material particles including central particles of LixFeyMzPO4 and a carbonaceous film which coats the central particles, wherein a particle size distribution thereof has maximum values of a relative particle amount on both fine and coarse particle sides. A particle diameter with the maximum relative particle amount on the fine particle side is in a range A of 0.70 ?m to 2.00 ?m, and a particle diameter with the maximum relative particle amount on the coarse particle side is in a range B of 7.00 ?m to 15.00 ?m. A difference between maximum values of a relative particle amount is 2.00% to 6.00%.

  • Patent number: 9923207
    Abstract: An electrode material which can improve the mobility of electrons and the mobility of ions at the same time, and, furthermore, does not have a problem of the impairment of the diffusion of lithium ions in a thin layer containing a carbonaceous electron-conductive substance so as to be excellent in terms of load characteristics and energy density, and an electrode and a lithium ion battery are provided. The electrode material of the invention is produced by forming a thin layer made of a carbonaceous electron-conductive substance on surfaces of primary particles made of an electrode active material, in which the carbonaceous electron-conductive substance contains nitrogen atoms.

  • Patent number: 5712630
    Abstract: A moving object identification system with a novel coding scheme achieves 75% transmission efficiency. With this system, a transmittable range is expanded. Logical value assignment for residual resonant oscillations in a residual resonant signal is performed by comparing a residual frequency with a threshold frequency. A wave energy reduction of an ASK modulated signal is used to decrease the energy of the signal in order to distinguish similar residual frequencies in the case of extremely close communication. Reliability of Write/Read instructions in this system is improved by employing a test writing before an actual writing and a voltage monitoring device.
