Definitions

  • the electrolyte decomposition product is incorporated into the Ca-containing conductive layer and stabilized, so that the contact opportunity between the electrolyte decomposition product and the silicate phase is significantly reduced. Therefore, the increase in the surface area of the lithium silicate phase due to the dissolution of the lithium silicate is suppressed, and the deterioration of the charge / discharge cycle characteristics due to the progress of the side reaction is suppressed.
  • the average particle size of the composite particles is, for example, 1 ⁇ m or more and 25 ⁇ m or less, and may be 4 ⁇ m or more and 15 ⁇ m or less. In the above particle size range, it is easy to relax the stress due to the volume change of the composite particle due to charging and discharging, and it is easy to obtain good cycle characteristics.
  • the surface area of the composite particles also becomes an appropriate size, and the volume decrease due to side reactions with non-aqueous electrolytes is suppressed.
  • the average particle size of the composite particle means the particle size (volume average particle size) at which the volume integrated value is 50% in the particle size distribution measured by the laser diffraction scattering method.
  • the measuring device for example, "LA-750" manufactured by HORIBA, Ltd. can be used. Since the Ca-containing conductive layer does not substantially affect the average particle size of the composite particles, the average particle size of the composite particles and the average particle size of the composite particles having the Ca-containing conductive layer may be regarded as equivalent.
  • FIG. 4A is a TEM photograph of a cross section of the composite particle having the Ca-containing conductive layer according to Example 1 described later, in the vicinity of the interface between the Ca-containing conductive layer and the composite particle.
  • FIG. 4B is a spectrum obtained when the region 1 in the Ca-containing conductive layer and the region 2 in the composite particle of FIG. 4A are analyzed by TEM-EELS.
  • the spectrum of region 1 has peaks derived from CaCO 3 at or near 349 eV and at or near 352 eV, similar to the CaCO 3 standard data. Therefore, it can be confirmed that CaCO 3 is present as a Ca component in the Ca-containing conductive layer.
  • no peak derived from CaCO 3 is observed at or near 349 eV and at or near 352 eV.
  • a step 1a of mixing silicon dioxide, a lithium compound, and a compound containing an element M, if necessary, to obtain a mixture, and a step 1b of firing the mixture to obtain a raw material silicate are performed.
  • the firing of step 1b is performed, for example, in an oxidizing atmosphere.
  • the firing temperature in step 1b is preferably 400 ° C. or higher and 1200 ° C. or lower, and more preferably 800 ° C. or higher and 1100 ° C. or lower.
  • the second step is not limited to the above.
  • silicon nanoparticles and nanoparticles of the raw material silicate may be synthesized and mixed without using a crushing device.
  • the Ca-containing conductive layer is formed by including the raw material of the Ca component in the raw material of the conductive material.
  • a raw material for the Ca component an organic substance containing Ca is desirable.
  • the organic substance containing Ca has a high affinity with the raw material of the conductive material, and easily dissolves or disperses uniformly in the raw material of the conductive material.
  • fatty acid calcium is desirable.
  • a Ca salt of a higher fatty acid for example, calcium stearate
  • Fatty acid calcium dissolves in the raw material of conductive materials such as pitch. As a result, the affinity between the raw material of the conductive material and the composite particles is enhanced, and the raw material of the conductive material is easily coated on the surface of the composite particles thinly.
  • FIG. 1 is a diagram schematically showing a cross section of a composite particle 11 having a Ca-containing conductive layer 15.
  • the composite particle 11 includes a silicate phase 12, a silicon (elemental Si) phase 13 dispersed in the silicate phase 12, and a compound 14 of the element M which is an optional component. At least a part of the surface of the composite particle 11 is covered with the Ca-containing conductive layer 15.
  • the negative electrode may include a negative electrode current collector and a negative electrode mixture layer supported on the surface of the negative electrode current collector.
  • the negative electrode mixture layer can be formed by applying a negative electrode slurry in which a negative electrode mixture is dispersed in a dispersion medium to the surface of a negative electrode current collector and drying it. The dried coating film may be rolled if necessary.
  • the negative electrode mixture layer may be formed on one surface of the negative electrode current collector, or may be formed on both surfaces.
  • An example of the structure of a non-aqueous electrolyte secondary battery is a structure in which an electrode group in which a positive electrode and a negative electrode are wound via a separator is housed in an exterior body together with a non-aqueous electrolyte.
  • the present invention is not limited to this, and other forms of electrodes may be applied.
  • a laminated electrode group in which a positive electrode and a negative electrode are laminated via a separator may be used.
  • the form of the non-aqueous electrolyte secondary battery is not limited, and may be, for example, a cylindrical type, a square type, a coin type, a button type, a laminated type, or the like.
  • the mass ratio of the Ca-containing conductive layer to the total of the composite particles and the Ca-containing conductive layer was determined from the mass difference of the composite particles before and after forming the Ca-containing conductive layer, and was 3% by mass.
  • the non-aqueous electrolyte secondary battery according to the present disclosure is useful as a main power source for mobile communication devices, portable electronic devices, and the like.
