NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME, AND LITHIUM SECONDARY BATTERY COMPRISING NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY

摘要

The negative electrode for a lithium secondary battery 10 includes: a current collector 11 having a plurality of bumps 11a on a surface thereof; a first active material layer 12 formed on the current collector 11; and a second active material layer 15 disposed on the first active material layer 12 and including a plurality of active material particles 14. Each of the plurality of active material particles 14 is located on a corresponding bump 11a of the current collector 11, and each of the first active material layer 12 and the plurality of active material particles 14 has a chemical composition represented as SiO x (0
