Abstract
A cathode material for a lithium-ion secondary battery made of agglomerated particles formed by agglomeration of a plurality of primary particles of a cathode active material represented by General Formula (1) below which are coated with a carbonaceous film, in which, in a case in which a cathode mixture layer including the cathode material, a conductive auxiliary agent, and a binding agent in a weight ratio (the cathode material/the conductive auxiliary agent/the binding agent) of 90:5:5 is calendered on a 30 μm-thick aluminum current collector at a total applied pressure of 5 t/250 mm, a film thickness change percentage of the cathode mixture layer before and after the calendering is 30% or less,LiADPO  (1).
