Title: NONAQUEOUS ELECTROLYTE BATTERY INORGANIC PARTICLES, AND NONAQUEOUS ELECTROLYTE BATTERY USING THESE
Abstract:
A purpose of the present invention is to provide nonaqueous electrolyte battery inorganic particles that enable provision of a nonaqueous electrolyte battery having excellent properties of safety and service life. Another purpose of the present invention is to provide an efficient and effective method for inspecting the metal absorption ability of nonaqueous electrolyte battery inorganic particles. The nonaqueous electrolyte battery inorganic particles according to the present invention include cation exchangers having a highly crystalline one-dimensional tunnel crystal structure. A method for inspecting the metal absorption ability of nonaqueous electrolyte battery inorganic particles according to the present embodiment includes: a step for preparing a nonaqueous electrolyte liquid containing metal ions at a specific concentration; a step for preparing a nonelectrolyte mixed liquid by adding, to the nonaqueous electrolyte liquid, a specific amount of the nonaqueous electrolyte battery inorganic particles; a step for agitating the nonelectrolyte mixed liquid under specific conditions; and a step for quantifying the metal ion concentration in the nonelectrolyte mixed liquid after agitation by means of a specific analyzer.
