负极活性物质，其制备方法以及包含负极活性物质的锂二次电池

Negative electrode active material, method for preparing the same and lithium secondary battery including negative electrode active material
Abstract:
A negative electrode active material, a method of preparing the negative electrode active material and a lithium secondary battery including the negative electrode active material are disclosed. A negative electrode active material includes a lithium titanate, wherein a portion of lithium of the lithium titanate is substituted by at least one selected from the group consisting of Sr, Ba, a mixture thereof and an alloy thereof, and thus a lithium secondary battery including the negative electrode active material may improve high-rate discharge characteristics.
Abstract(Chinese):
