  • NEGATIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERIES, AND SECONDARY BATTERY
    Publication number: 20240413327
    Abstract: The disclosed negative electrode active material for a secondary battery includes silicate composite particles each including a silicate phase, and silicon particles dispersed in the silicate phase. A peak of an oxygen K-edge energy loss near edge structure (ELNES) at an interface between the silicate phase and the silicon particles is shifted to a lower energy side by 2.0 eV to 3.0 eV relative to a peak of the oxygen K-edge energy loss near edge structure in the silicate phase.

  • COMPOSITE PARTICLES FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
    Publication number: 20240038974
    Abstract: Composite particles for a non-aqueous electrolyte secondary battery include a lithium zirconate phase, and a silicon phase dispersed in the lithium zirconate phase. In the composite particles, a content proportion MZr of zirconium in all elements other than oxygen is, for example, 14.6 mass % or more and 54.6 mass % or less, and a content proportion MLi of lithium in all elements other than oxygen is, for example, 0.9 mass % or more and 10.4. mass % or less.
