    • Disclosed is a lithium secondary battery comprising a cathode (C), an anode (A), a separator and an electrolyte, wherein the battery has a weight ratio (A/C) of anode active material (A) to cathode active material (C) per unit area of each electrode of between 0.44 and 0.70, and shows a charge cut-off voltage of between 4.35V and 4.6V. The high-voltage lithium secondary battery satisfies capacity balance by controlling the weight ratio (A/C) of anode active material (A) to cathode active material (C) per unit area of each electrode. Therefore, it is possible to significantly increase the available capacity and average discharge voltage of a battery using a lithium/cobalt-based cathode active material, which shows an available capacity of about 50% in a conventional 4.2V-battery. Additionally, it is possible to significantly improve battery safety under overcharge conditions, and thus to provide a high-voltage and high-capacity lithium secondary battery having excellent safety and long service life.
    • 公开了一种锂二次电池,其包含阴极(C),阳极(A),隔膜和电解质,其中电池具有负极活性物质(A)与正极活性物质(C)的重量比(A / C) )每个电极的每单位面积在0.44和0.70之间,并且显示在4.35V和4.6V之间的电荷截止电压。 高压锂二次电池通过控制每个电极的每单位面积的负极活性物质(A)与阴极活性物质(C)的重量比(A / C)来满足容量平衡。 因此,可以使用基于锂/钴的阴极活性材料显着提高电池的可用容量和平均放电电压,其在常规4.2V电池中显示出约50%的可用容量。 此外,可以在过充电条件下显着提高电池安全性,从而提供具有优异的安全性和长使用寿命的高电压和高容量的锂二次电池。
