  • Publication number: 20210207030
    Abstract: A polarizing film including a polarizer that is a cured product of a polymerizable liquid crystal composition is provided. The polymerizable liquid crystal composition contains both a polymerizable liquid crystal compound having at least one polymerizable group and a dichroic coloring matter. The polarizer is laminated on a surface, having a pore size of 0.45 nm to 0.57 nm, of a base material. The pore size is obtained by converting, into a diameter, an average free volume radius calculated by a positron lifetime measurement method in which the positron lifetime is measured by irradiating the surface with positrons with an injection energy of 3 kV.

  • Publication number: 20190355989
    Abstract: Provided are excellent coated lithium-nickel composite oxide particles with which it is possible, due to the high environmental stability thereof, to minimize the incidence of impurities owing to absorption of moisture and carbon dioxide gas, said particles having high adhesiveness such that the coating layer does not easily delaminate, and having lithium-ion conductivity. The coated lithium-nickel composite oxide particles, in which an electroconductive polymer is cross-linked to the lithium-nickel composite oxide particles by a three-dimensional structure, are electrically and ionically conductive, and the compound is capable of suppressing the transmission of moisture and carbon dioxide. It is therefore possible to provide coated lithium-nickel composite oxide particles for a lithium-ion cell positive-electrode active substance that is excellent for use in a lithium-ion cell.

  • Patent number: 10439214
    Abstract: To provide excellent lithium-nickel composite oxide particles which have high environmental stability and are thus capable of suppressing generation of impurities due to absorption of moisture and a carbon dioxide gas, while being prevented from easy separation of a coating film because of high adhesion thereof and having lithium ion conductivity. Coated lithium-nickel composite oxide particles, which are obtained by coating the surfaces of lithium-nickel composite oxide particles with a predetermined coating material, have electrical conductivity and ion conductivity and are capable of suppressing permeation of moisture and a carbon dioxide gas. Consequently, the present invention is able to provide coated lithium-nickel composite oxide particles for positive electrode active materials of lithium ion batteries, which is excellent for use in lithium ion batteries.

  • Patent number: 10374226
    Abstract: Provided are: superior coated lithium-nickel composite oxide particles which have an environmental stability that enables suppression of the occurrence of impurities due to absorption of moisture or carbon dioxide, which have high adhesion that prevents a coating layer from readily separating, and which have lithium ion conductivity; and a method for producing such particles. Provided is a method for producing coated lithium-nickel composite oxide particles, the method being characterized by contacting a cyclic siloxane with the surfaces of nickel-based lithium-nickel composite oxide particles to form surface coats. The particles have high adhesion to a coating layer and as a compound can suppress the permeation of moisture and carbon dioxide, and also have lithium ion conductivity. It is therefore possible to provide coated lithium-nickel composite oxide particles that are excellent for use in lithium ion cells.
