Lithium titanate, negative electrode including the lithium titanate, and secondary lithium battery containing the electrode

摘要

A negative electrode for a lithium secondary battery that includes, as a negative active material, a lithium titanate (Li4Ti5O12) compound containing 0.004 parts by weight or less of phosphorous (P) and 0.007 parts by weight or less of potassium (K) based on 100 parts by weight of lithium titanate, a binder, and a conductive agent, and a lithium secondary battery including the negative electrode.
