  • LITHIUM ION SECONDARY BATTERY ELECTRODE, PRODUCTION METHOD FOR SAME, AND LITHIUM ION SECONDARY BATTERY
    Publication number: 20210057732
    Abstract: An electrode for a lithium ion secondary battery, 10, comprises an electrode active substance layer 11, and an insulating layer 12 provided on the surface of the electrode active substance layer 11, wherein the insulating layer 12 comprises an insulative microparticle and a binder for an insulating layer. The interface 12A between the insulating layer 12 and the electrode active substance layer 11 has a roughness of 2 ?m or lower as calculated from observation using a scanning electron microscope.

  • Electrode manufacturing method, electrode, and secondary battery
    Patent number: 10770743
    Abstract: A method for manufacturing an electrode having a laminated body including an insulating layer laminated on an electrode active material layer, said method comprising: a step of laminating an insulating layer on an electrode active material layer formed on a base, such that a thickness value of the insulating layer is at least twice a surface roughness Rz value of the electrode active material layer, the surface roughness Rz value being a ten point average roughness as measured in accordance with JIS B0601 1994.

  • Lithium ion secondary battery
    Patent number: 10566650
    Abstract: A lithium ion secondary battery 10 includes at least one cell obtained by laminating a positive electrode 1, an electrolyte layer 2, and a negative electrode 3 in this order. The electrolyte layer 2 contains a fluoride. The negative electrode 3 has a negative electrode active material layer containing a silicon compound. At least one of the negative electrodes 3 has a mass ratio of fluorine/silicon (F/Si ratio) of 1.0 or less on a surface of the negative electrode active material layer.
