Abstract
Official abstract text for this publication.
A lithium-transition metal compound powder for a positive-electrode material of lithium secondary batteries can include a lithium-transition metal compound that is capable of an insertion and elimination of lithium ions. The particles in the powder contain, in the inner part thereof, a compound that, when analyzed by an SEM-EDX method, has peaks derived from Group-16 elements belonging to the third or later periods of the periodic table and Group-5 to Group-7 elements belonging to the fifth and sixth periods of the periodic table.
