    • A lithium secondary battery according to the present invention comprises: a positive electrode having a positive electrode active material composed of a reversible lithium intercalation material; a negative electrode having a negative electrode active material composed of a reversible lithium intercalation material; and a separator interposed between said positive electrode and said negative electrode, and in the positive electrode active material, at least one material which shows a positive sign of a total sum of entropy heat from a discharged state to a charged state is mixed with at least one material which shows a negative sign of a total sum of an entropy heat from a discharged state to a charged state. In a battery having such a construction, the amount of entropy heat during charge is reduced compared with a battery employing only a material which shows a positive sign of the total sum of entropy heat. As a result of this, a battery produced in accordance with the present invention achieves an improved cycle characteristic, and thereby is capable of preventing a large deterioration of a battery performance.
    • 根据本发明的锂二次电池包括:正极,具有由可逆的锂嵌入材料构成的正极活性物质;负极,具有由可逆的锂嵌入材料构成的负极活性物质; 和分离器插入在所述正极和所述负极之间,并且在正极活性物质中,至少一种显示从放电状态到充电状态的熵热的总和的正征的材料与至少一个 显示从放电状态到充电状态的熵热的总和的负号的材料。 在具有这种结构的电池中,与仅使用显示熵热总和的材料的电池相比,充电期间的熵热量减少。 结果,根据本发明制造的电池实现了改进的循环特性,从而能够防止电池性能的大的劣化。

    • In an information recording/reproducing apparatus constructed of: a buffer for storing therein consecutive recording data in a unit of two dimensional conversion; a coding device for converting the consecutive recording data into a two-dimensional data arrangement arranged by "n" lines and "m" columns corresponding to said unit of data; a recording device for subdividing said two-dimensional data arrangement arranged by "n" lines and "m" columns so as to be read out, and for controlling "m" pieces of light sources in accordance with these data series; and an optical apparatus for converging luminous fluxes from said "m" pieces of light sources so as to form "m" pieces of spots on a disk plane, the recording data is recorded on the disk plane as an optically distringuishable pit group having two-dimensionally extended areas arranged by "n" lines and "m" columns. During a reproducing operation, the reflected light is detected by "m" pieces of detectors; "m" columns of one-dimensional data series are generated from the reflected light detected by these detectors in a generator; and also consecutive data is reproduced from the two dimensional data arranged by "n" lines and "m" columns in a decoder.
