Claim 0:
1. A secondary battery comprising:
a positive electrode;
a negative electrode; and
an electrolyte,
wherein the positive electrode comprises a positive active material of a lithium metal oxide including a reaction-inducing substance in which the lithium metal oxide is in the form of secondary particles of agglomerated primary particles,
wherein the reaction-inducing substance is located between the agglomerated primary particles constituting secondary particles,
wherein the reaction-inducing substance forms a reaction product by consuming thermal energy when exposed to a predetermined temperature or higher in a use environment of the secondary battery, thereby improving thermal safety of the secondary battery, and
wherein the reaction-inducing substance comprises Li and Si.
