Definitions

  • any of the illustrated lower limits and any of the illustrated upper limits can be arbitrarily combined as long as the lower limit is not greater than or equal to the upper limit.
  • a plurality of materials are exemplified, one of them may be selected and used alone, or two or more may be used in combination.
  • Secondary batteries include at least non-aqueous electrolyte secondary batteries such as lithium-ion batteries, and all-solid-state batteries.
  • All of the N-type or higher constituent elements Mi may be elements having an atomic weight of 29 (Cu) or less. In this case, the average atomic weight of the N-type or higher constituent element Mi is further reduced, making it easier to further increase the capacity density of the composite material.
  • substantially all of the N-type or higher constituent element Mi forms an intermetallic compound, and the fact that the content of a simple substance of the metal element is substantially 0% by mass is confirmed by the X-ray diffraction of the composite material. It can be confirmed by measuring.
  • the negative electrode active material for secondary batteries according to the present invention is effective as a negative electrode active material for secondary batteries used in mobile applications (electric vehicles, mobile communication devices, portable electronic devices, etc.).
