摘要： Disclosed are a method for preparing an active material, the surface of which is modified, using a surface treatment solution and an active material prepared thereby, and more particularly, an active material in which the amount of impurities on the surface thereof is reduced and on the surface of which a metal oxide configured to cut off direct contact with an electrolyte is uniformly disposed by collectively performing both a washing process and a surface treatment process using a surface treatment solution having a novel composition.
