Negative electrode active material and lithium secondary battery including the same
The present invention relates to a silicon-carbon-based composite negative electrode active material, and a negative electrode for a secondary battery and a lithium secondary battery including the same, and particularly to a silicon-carbon-based composite negative electrode active material, in which physical stability is improved by including a carbon-based core capable of intercalating and deintercalating lithium ions and at least one silicon particle included in the carbon-based core and disposed in the form of being distributed in an outer portion of the carbon-based core, and a negative electrode for a secondary battery and a lithium secondary battery in which life characteristics are improved by including the same.
