    摘要: A positive electrode material that can form a positive electrode mixture containing composition with reduced changes over time and high productivity, a manufacturing method thereof, a non-aqueous rechargeable battery less likely to swell and having a high storage characteristic during storage at high temperatures, and a positive electrode that can form the battery are provided. The object is solved by providing a positive electrode material having a coating layer of an organic silane compound on a surface of a positive electrode active material made of a lithium nickel composite oxide represented by the general compositional formula (1): Li1+xMO2 where −0.5≦x≦0.5, M represents a group of at least two elements including at least one of Mn and Co and Ni, and 20≦a≦100 and 50≦a+b+c≦100 when the ratios (mol %) of Ni, Mn, and Co in the elements forming M are a, b, and c, respectively.
