摘要

PROBLEM TO BE SOLVED: To provide a pre-dope material in which the paste hardly gels when a paste containing the pre-dope material is prepared and stored. According to one embodiment of the present invention, LiaMe1bX1(1-b)O4 (5≦a≦6, 0.8≦b≦1, and Me1 is selected from the group consisting of Co, Mn, Fe, and Ni 1 Element or two or more elements, X1 is a metal element other than Co, Mn, Fe and Ni), and a metal oxide A having an inverted fluorite structure and LipMe2qX2rO2 (0≦p≦1, 0.5 ≦q≦1, 0≦r0.1, Me2 is one or more elements selected from the group consisting of Co, Mn, Fe and Ni, and X2 is a metal other than Co, Mn, Fe and Ni. A metal oxide B represented by an element), and the metal oxide B covers at least a part of the metal oxide A. [Selection diagram] Fig. 5
