In the present invention LiF mainly, and is distributed on the surface of the Si material, for example, it may be continuous and uniformly distributed throughout the Si surface of a particulate (granular), or LiF the light onto the fine particles on the Si surface of the particulate It can be continuously distributed. To be preferably distributed in the form of the latter when considering the ease of the manufacturing process side can be made in a form that are distributed continuously or discontinuously on the surface of the Si material. [60] [61] In the present invention, it is that the LiF is covering the surface of the Si material means that LiF has a relatively high rate of distribution to the surface of the Si material than the proportion present as an independent phase such as a single powder or agglomerates. Preferably when at least 50% or more is distributed, and the distribution is less than 50% of the Si particle surface area it may be difficult to exert the effects, such as improving the capacity retention ratio desired. [62] [63] In the present invention, the Si particle is a particle diameter (D50) is 1nm to 700nm.

[64] [65] If the Si-LiF mixed particles in an embodiment of the present invention is the LiF coated continuously or discontinuously on the surface of the particulate Si is a coating layer of LiF is 0.1nm to 50nm. [66] [67] The grain size of Si is too large, and to the particles inside the Si without reacting with the lithium in a surface layer of easy-Si particles to react with the lithium is inserted, desorption of lithium can be up and the cracking of the particle surface portion expands, which undifferentiated is caused while repeating It can be. For this reason, Si is can take place the separation and / or eliminated, or Si thereto a whole and can keep the contact of the not lowered because the charge-discharge capacity of the rapid cycle house accordingly. Therefore, Si is required to be micronized to a size that does not happen in the microstructure. Therefore, the grain size (La) of Si is not more than 10nm is to 20nm, preferably. [68] [69] The mixed particles, as will be described later, by the addition of LiF in the step of micronized by Si in the mechanical mixture of LiF and Si or a mixture or composite, a LiF can be obtained in such a way as to cover the surface of the Si particles.

On the other hand, the upper limit of the thickness of the coating layer may be 100nm, 90nm, 80nm, 70nm, 60m within this range. Whereby the composite particles coated with the said coating layer has an effect of improving the conductivity of the composite particles it can be prevented from being exposed to the outside Si-LiF mixed particles by the coating. In addition, because the higher the storage stability of the active material particles by the coating thickness of the coating layer is made thick to the extent possible.
