    • Disclosed is an electrolyte for batteries, comprising: (a) an electrolyte salt; (b) an organic solvent; (c) a first compound having an oxidation initiation voltage (vs. Li/Li+) higher than the operating voltage of a cathode; and (d) a second reversible compound having an oxidation initiation voltage higher than the operating voltage of the cathode, but lower than the oxidation initiation voltage of the first compound. Also disclosed is a lithium secondary battery comprising said electrolyte. In the lithium secondary battery, two compounds having different safety improvement actions at a voltage higher than the operating voltage of the cathode are used in combination as electrolyte components. Thus, the safety of the secondary battery in an overcharged state can be ensured, and at the same time, the deterioration of the battery can be prevented from occurring when it is repeatedly cycled, continuously charged and stored at high temperature for a long time.
    • 公开了一种用于电池的电解质,其包括:(a)电解质盐; (b)有机溶剂; (c)具有高于阴极的工作电压的氧化起始电压(相对于Li / Li +)的第一化合物; 和(d)具有高于阴极的工作电压但低于第一化合物的氧化起始电压的氧化起始电压的第二可逆化合物。 还公开了包含所述电解质的锂二次电池。 在锂二次电池中,作为电解质成分组合使用具有比阴极的工作电压高的电压具有不同安全性改善作用的两种化合物。 因此,可以确保二次电池处于过充电状态的安全性,并且同时可以防止在重复循环,连续充电并长时间在高温下储存时发生电池的劣化。

    • An LCD device is discussed, which comprises first and second substrates confronting each other; a liquid crystal layer between the first and second substrates; and red, green, blue, and fourth color filters on the first substrate; wherein the fourth color filter is formed of any color whose transparency is better than that of at least one of the red, green, and blue color filters, and wherein an effective area of the fourth color filter is smaller than that of at least one of the red, green, and blue color filters. The LCD device can display white color with good transparency by properly adjusting the effective areas of the four color filters, whereby there is no need to modulate light for display of the white color in a backlight unit, to thereby improve luminance of light emitted from the backlight unit.
    • 讨论了一种LCD装置,其包括彼此面对的第一和第二基板; 第一和第二基板之间的液晶层; 以及第一基板上的红,绿,蓝和第四滤色器; 其中所述第四滤色器由透明度优于红色,绿色和蓝色滤色器中的至少一种的任何颜色形成,并且其中所述第四滤色器的有效面积小于所述第四滤色器中的至少一种的有效面积 红色,绿色和蓝色滤色镜。 LCD装置可以通过适当地调节四个滤色器的有效面积来显示具有良好透明度的白色,从而不需要调制用于在背光单元中显示白色的光,从而提高从背光单元发出的光的亮度 背光单元。
