Abstract
Provided is a method for manufacturing an anode active material particle having good lithium ion conducting property and good formability. The method for manufacturing an anode active material includes a first step of making a carbon particle with pores have contact with an ionic liquid having a lithium ion conducting property, and making the ionic liquid flow into the pores, and a second step of washing the carbon particle after the first step, while leaving the ion liquid inside the pores.
Claims10
A method for manufacturing an anode active material particle comprising:
- a first step of contacting a carbon particle having pores with an ionic liquid in which a lithium salt is dissolved, and making the ionic liquid flow into the pores;
- and
- a second step of washing the carbon particle with an organic solvent after the first step, while leaving the ionic liquid inside the pores.
Dependencies are inferred from the claim text.
