摘要
A lithium transition metal based compound powder for a lithium secondary battery positive electrode material, characterized by including a lithium transition metal based compound, which has a function of enabling insertion and elimination of lithium ions, as a primary component and being produced by conducting firing after at least one type of compound (hereafter referred to as "Additive 1") containing at least one type of element (hereafter referred to as "Additive element 1") selected from B and Bi and at least one type of compound (hereafter referred to as "Additive 2") containing at least one type of element (hereafter referred to as "Additive element 2") selected from Mo and W are added in combination to a raw material of the primary component at a ratio of a total of Additive 1 and Additive 2 to a total amount of moles of transition metal elements in the raw material of the primary component of 0.01 percent by mole or more, and less than 2 percent by mole.
