摘要
PROBLEM TO BE SOLVED: To provide a sheet-like active material particle-containing mold for a secondary battery electrode, which is arranged by use of an oxide active material of 3 μm or less in volume-average particle diameter D, and which enables the suppression of the worsening in battery performance, such as the decrease in battery energy density or the increase in internal resistance, and enables the exhibition of good moldability even in the case of forming an active material layer according to compression molding.SOLUTION: A sheet-like active material particle-containing mold for a secondary battery electrode comprises: 65-90 wt% of oxide active material small particles including primary particles of over 1 to 3 μm in volume-average particle diameter (D); 5-30 wt% of a conductive material large particles of carbon material having a number-average particle crushing strength of 3 MPa or larger and including primary particles of 8-50 μm in volume-average particle diameter (D); and 0.5-5 wt% of an insulative binding material. Particularly, the oxide active material small particles include a compound arranged by substituting, with other metal ions, part of ions of a lithium titanate, a lithium manganate or/and a lithium manganate, having Spinel structure.SELECTED DRAWING: None
