摘要： An anode material capable of providing a high capacity and improving cycle characteristics and a manufacturing method thereof, and a battery are provided. The anode material has a reaction phase containing an element capable of generating an intermetallic compound with Li and C. In this reaction phase, a half value width of a diffraction peak by X-ray diffraction is preferably 0.5° or more. Further, in this anode material, it is preferable that a peak of C is obtained in a region lower than 284.5 eV by XPS. In the case that Sn is contained as an element capable of generating an intermetallic compound with Li, it is preferable that an energy difference between a peak of 3d5/2 orbit of Sn and a peak of 1s orbit of C is larger than 200.1 eV. It becomes thereby possible that cohesion or crystallization of the element capable of generating an intermetallic compound with Li associated with charge and discharge can be inhibited.

摘要： An alloy powder containing at least one element selected from the group consisting of the Group 14 elements exclusive of C and the Group 13 elements exclusive of Tl is subjected to a mechanical milling treatment, to obtain a negative electrode active material. Alternately, a raw material including a powder containing at least one element selected from the group consisting of the Group 14 elements exclusive of C and the Group 13 elements exclusive of Tl is subjected to a mechanical alloying treatment at a reaction temperature of below 90° C., to obtain a negative electrode active material. The negative electrode active material is restrained from the expansion and contraction attendant on the doping and dedoping of lithium which is characteristic of the alloy material, a negative electrode using the negative electrode active material is restrained from the change to a particulate form attendant on charging and discharging, and a nonaqueous electrolyte cell using the negative electrode shows both an excellent charging-discharging cycle characteristic and a high discharging capacity.

摘要： An anode and a battery capable of realizing a high capacity and improving charge and discharge cycle characteristics, and manufacturing methods thereof are provided. An anode active material layer (12) contains a particulate anode active material (12A) including a simple substance or a compound of an element capable of forming an alloy with Li, a particulate binder (12B) including a copolymer of vinylidene fluoride or polyvinylidene fluoride, and a conductive agent (12C). The anode active material layer (12) is formed by using a dispersion medium having a swelling degree of 10% or less to the binder (12B), specifically pure water or the like. The particulate binder (12B) functions as a cushion to absorb expansion and shrinkage of the anode active material (12A) due to charge and discharge, and lowering of electron conductivity caused by generation of cracks or separation is prevented. Further, since the anode active material (12A) is not covered with the binder (12B), electrode reaction is well performed.
