More Information
Summary:The present disclosure relates to a negative electrode active material for an electrochemical device which has improved quick charging characteristics. The negative electrode active material includes two types of graphite particles having a different particle diameter and shows a bimodal distribution, wherein the ratio of particle diameter (D50) of the first graphite particles/particle diameter (D50) of the second graphite particles is larger than 1.7.
