Abstract
The present invention aims to provide an electrode for lithium ion batteries which exhibits excellent electrical conductivity even if its thickness is large. The electrode for lithium ion batteries of the present invention includes a first main surface to be located adjacent to a separator of a lithium ion battery and a second main surface to be located adjacent to a current collector of the lithium ion battery. The electrode has a thickness of 150 to 5000 μm. The electrode contains, between the first main surface and the second main surface, a conductive member (A) made of an electronically conductive material and a large number of active material particles (B). At least part of the conductive member (A) forms a conductive path that electrically connects the first main surface to the second main surface. The conductive path is in contact with the active material particles (B) around the conductive path.
