    • Carbon powder having low temperature calcined carbon derived from pitch adhered to a portion of the surface of natural graphite powder is obtained by solids mixing of natural graphite powder and pitch powder as a carbon precursor followed by heat treatment at 900-1500° C. to carbonize the pitch. The amount of pitch powder is such that the ratio V2/V1 of the pore volume V2 of pores having a diameter of 50-200 nm to the pore volume V1 of pores having a diameter of 2-50 nm in a pore size distribution curve obtained by analysis of the nitrogen desorption isotherm of the resulting carbon powder by the BJH method is at least 1. This carbon powder can be used as a negative electrode material for a nonaqueous secondary battery able to operate at low temperatures.
    • 通过将天然石墨粉末和作为碳前体的沥青粉末固体混合,然后在900-1500℃进行热处理以碳化,得到具有由附着在天然石墨粉末的表面部分上的沥青衍生的低温煅烧碳的碳粉末 球场。 间距粉末的量使得在获得的孔径分布曲线中,直径为50-200nm的孔的孔体积V2与直径为2-50nm的孔的孔体积V1的比V2 / V1 通过用BJH法分析得到的碳粉末的氮解吸等温线为至少1.该碳粉末可以用作能够在低温下操作的非水二次电池的负极材料。

    • Positive and negative terminals formed on a top face of a unit cell and positive and negative terminals formed on a surface of a circuit board opposed to the unit cell are electrically connected to each other by connectors. The connectors each include an elastic body formed from an elastic material, and a conductor which is placed so as to be exposed on upper and lower surfaces of the elastic body and which serves for electrically connecting those exposed portions to each other. By elastic restoring force of the elastic body generated by elastic compression of the elastic body between the terminals, the upper and lower surfaces of the connectors are put into press contact between the opposing positive and negative terminals of the unit cell and the circuit board, by which their electrical connection is maintained.
    • 形成在单元电池的顶面上的正极和负极端子和形成在与单元电池相对的电路板的表面上形成的正极端子和负极端子通过连接器彼此电连接。 连接器各自包括由弹性材料形成的弹性体,以及布置成暴露在弹性体的上表面和下表面上并且用于将这些暴露部分彼此电连接的导体。 通过由端子之间的弹性体的弹性压缩产生的弹性体的弹性恢复力,连接器的上表面和下表面在单元电池和电路板的相对的正极和负极端子之间被压接,由 它们的电气连接被维持。
