AI Technical Summary

Problems solved by technology

In this case, since the insulating binder is partially bonded to the active material particles, the pre-doping is not uniform, and there is a problem that the so-called SEI (Solid Electrolyte Interface, Solid Electrolyte Interface) film is also uneven.

[0065] 1. Manufacturing method of electrode material

[0066] In the manufacturing method of the electrode material of the present disclosure, in the presence of an alkali metal supply source and a solvent, an amorphous aggregate containing at least an active material is sent out in a sending direction while being dynamically pressurized in a dynamic pressurization unit, and The aggregates are continuously discharged from the dynamic pressurization unit toward the delivery direction.

[0067] It should be noted that in this embodiment, the presence of an alkali metal supply source refers to the case where the alkali metal supply source exists outside the aggregate, also includes the case where the alkali metal supply source exists in the aggregate, and also includes the case where the alkali metal supply source exists outside the aggregate. A condition in which a source is present within an aggregate while being present outside the aggregate.

[0068] As an alkali metal in th...
