NOVELTY - The electrode has a negative active material layer provided on a current collector and comprising negative active material with amorphous carbon i.e. soft carbon, having average aspect ratio of 1.1 to 6. The amorphous carbon is included in an amount of about 55.5 wt.% to about 99.5 wt.% based on total weight of the negative active material layer. The amorphous carbon has lattice constant in range of 10 Angstrom to 30 Angstrom and average particle diameter in range of 5 micrometer to 20 micrometer and 7 micrometer to 15 micrometer.    USE - Negative electrode for a lithium battery (claimed) i.e. rechargeable lithium battery, utilized in an integrated starter and generator system for an auto engine of a vehicle.    ADVANTAGE - The negative active material including the amorphous carbon has a shorter path through which electrons flow when the amorphous carbon has aspect ratio within the range so as to decrease internal resistance of the electrode and to include a binder in smaller amount, thus preventing deterioration of electrical conductivity resulting from the binder, and hence realizing the rechargeable lithium battery having high cycle-life and output characteristics.    DETAILED DESCRIPTION - The negative active material is conductive material selected from a group consisting of carbon-based material e.g. natural graphite, artificial graphite, carbon black, acetylene black, ketjen black and carbon fiber, metal-based material e.g. metal powder and metal fiber made of copper, nickel, aluminum and silver and conductive polymer i.e. polyphenylene derivative, and binder selected from a group consisting of polyvinylalcohol, carboxylmethylcellulose, hydroxypropylcellulose, PVC, carboxylated PVC, polyvinylfluoride, ethylene oxide-containing polymer, polyvinylpyrrolidone, polyurethane, PTFE, polyvinylidene fluoride, polyethylene, polypropylene, styrene-butadiene rubber, acrylated styrene-butadiene rubber, epoxy resin and nylon. An INDEPENDENT CLAIM is also included for a lithium battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing relationship between voltage and capacity and output characteristics of rechargeable lithium battery cells.
