摘要: Performance is improved. There is provided a negative electrode material for a battery, in which the negative electrode material includes carbon, sodium tungstate, and silicon particles 33 including silicon, and in the silicon particle 33, a ratio of the amount of Si in Si2p derived from elemental silicon to the amount of Si in Si2p derived from SiO2 in a surface layer when measured by X-ray photoelectron spectroscopy is 3 or more on an atomic concentration basis.

摘要: Provided is a copper strip for edgewise bending, which is edgewise-bent under a condition that a ratio R/W of a bending radius R to a width W is 5.0 or less, in which a thickness t is set to be in a range of 1 mm or more and 10 mm or less, and using an intersection of a straight line which is in contact with a surface and is parallel to a width direction and a straight line which is in contact with an end face and is perpendicular to the width direction as a reference in a cross section orthogonal to a longitudinal direction, an area ratio B/(A + B) to be calculated from an area (A) of a portion where copper is present and an area (B) of a portion where copper is not present is in a range of more than 10% and 100% or less in a square region where the length of one side is 1/10 of the thickness t.
