  "textContent": "The present invention relates to a composition for coating a negative electrode active material, a negative electrode active material for a secondary battery, a negative electrode containing the same, and a lithium secondary battery containing the negative electrode. Particularly, a composition for coating a negative electrode active material, which includes tannic acid, a negative electrode active material for a secondary battery whose surface is coated with a tannic acid-based coating film, a negative electrode for a secondary battery, which includes the negative electrode active material, and a lithium secondary battery including the negative electrode may reduce volume expansion and prevent damage in charging/discharging of the negative electrode active material. Therefore, the secondary battery including the negative electrode of the present invention ultimately improves resistance and life span characteristics.",
