摘要：
Provided is a negative electrode active material for secondary batteries that is capable of inhibiting negative electrode swelling and the decline of the charge/discharge cycle characteristics of a battery. A negative electrode active material for secondary batteries according to the present disclosure is characterized by including a Si-based material, activated carbon, and a conductive material, and in that the Si-based material and the conductive material are carried in pores of the activated carbon.
