▎ 摘  要

NOVELTY - An apparatus comprises an electrode active layer (100) comprising a network of high aspect ratio carbon elements defining void spaces within the network, electrode active material particles (300) arranged in the void spaces within the network and enmeshed in the network, and a surface treatment on the surface of the high aspect ratio carbon elements which promotes adhesion between the high aspect ratio carbon elements and the active material particles. USE - Apparatus used in lithium batteries. Uses included but are not limited to medical devices, electric cars, airplanes, laptop computers, cell phones, and cameras. ADVANTAGE - The apparatus exhibits excellent mechanical stability without the need for bulk polymer binders. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrode. 10Electrode 100Active layer 101Current collector 102Adhesion layer 300Active material particles
