  • Publication number: 20220140390
    Abstract: A non-aqueous electrolyte secondary battery which is an example of an embodiment of the present invention includes an electrode body around which a positive electrode and a negative electrode are spirally wound via a separator, a non-aqueous electrolyte, and a bottomed cylindrical outer can that accommodates the electrode body and the non-aqueous electrolyte. The negative electrode has a negative electrode core and a negative electrode mixture layer that is provided on the surface of the negative electrode core. The electrode body has, on the outer peripheral surface, an exposed portion where the surface of the negative electrode core is exposed, and the exposed portion is in contact with the inner surface of the outer can. The non-aqueous electrolyte comprises 0.1 to 1.0 mass % of a diisocyanate compound.

  • Publication number: 20210313564
    Abstract: A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and an electrolyte liquid. The negative electrode includes a negative electrode mixture layer containing a first negative electrode active material and a negative electrode collector to which the negative electrode mixture layer is adhered. The first negative electrode active material contains a first lithium silicate phase containing lithium, silicon, and oxygen and first silicon particles dispersed in the first lithium silicate phase. An atomic ratio A1:O/Si of the oxygen to the silicon in the first lithium silicate phase satisfies a relationship of 2<A1?3. At a surface side of the negative electrode, an existence ratio of the first negative electrode active material in the negative electrode mixture layer is high as compared to that at a negative electrode collector side of the negative electrode.
