Abstract

The present invention provides a negative electrode for a secondary battery and a secondary battery comprising same wherein the negative electrode for a secondary battery is configured such that a negative electrode mixture which contains negative electrode active materials is deposited on a current collector. The negative electrode active materials are lithium titanium oxide (LTO) particles on the surface of each of which a cross linking polymer coating layer is formed. The lithium titanium oxide particles on which the coating layers are formed maintain the pore structures formed between the particles. The cross -linking polymer is a phosphate- based compound.
