  "textContent": "A negative electrode for a rechargeable lithium battery which is obtained by sintering under a non-oxidizing atmosphere, in the form of a layer on a surface of a metal foil current collector (1), an anode mix containing a binder (3) and particles of active material (4) containing silicon and/or a silicon alloy; the negative electrode being characterized in that the metal foil current collector has projections (2) and recesses on its surface (1a), the projection is shaped to have a recurved side face portion (2a) that curves more outwardly as it extends closer to a distal end of the projection, and the binder penetrates into spaces defined by the recurved side face portions.",
