    • A rechargeable lithium battery includes an electrolyte including an additive such as an ethylene carbonate-based compound represented by Chemical Formula 1 and a silicon-included compound, and a negative electrode including a negative active material including an active element selected from the group consisting of Si, Sn, Ga, Cd, Al, Pb, Zn, Bi, In, Mg, and Ge. In Chemical formula 1, X and Y are independently selected from the group consisting of hydrogen, a halogen, and a C1 through C5 fluoroalkyl, provided that at least one of X and Y is selected from the group consisting of a halogen and a C1 through C5 fluoroalkyl.The rechargeable lithium battery has a suppressed volume expansion characteristic due to a high-capacity negative active material, and has excellent reliability and cycle-life characteristics.
    • 可再充电锂电池包括包含由化学式1表示的碳酸亚乙酯类化合物和含硅化合物等添加剂的电解质,负极包含负极活性物质,负极活性物质含有选自Si ,Sn,Ga,Cd,Al,Pb,Zn,Bi,In,Mg和Ge。 在化学式1中,X和Y独立地选自氢,卤素和C 1至C 5氟烷基,条件是X和Y中的至少一个选自卤素和C 1至 C5氟烷基。 可充电锂电池由于容量大的负极活性物质而具有抑制的体积膨胀特性,并且具有优异的可靠性和循环寿命特性。
