PROBLEM TO BE SOLVED: To provide a nonaqueous secondary cell with superior loading property and a highly safe characteristic. SOLUTION: The nonaqueous secondary cell is composed of a negative electrode comprising an insulating particle in a negative electrode mixture. As the insulating particle, it is preferable, even though its shape may be ball-like, fiber-like, flake-like, or lump-like, that it be different from the shape of the active substance for the negative electrode, and it is favorable that its material is anything of glass, plastics, or ceramics. It is preferable that the content of the insulating particle in the negative electrode mixture be in 2 to 10 wt.%. |
