Abstract
The objective of the present invention is to provide an electrode for a lithium ion battery which has excellent electron conductivity even when the thickness of the electrode is increased. The electrode for a lithium ion battery according to the present invention includes a first principal surface located on a separator side of the lithium ion battery, and a second principal surface located on a current collector side, wherein the electrode has a thickness of 50 to 5000 μm, and the electrode includes, between the first principal surface and the second principal surface, short fibers (A) having an average fiber length of 50 nm or more and less than 100 μm, long fibers (B) having an average fiber length of 100 μm or more and 1000 μm or less, and active material particles (C), and the short fibers (A) and the long fibers (B) are electroconductive fibers.
