    • PURPOSE: Provided is a non-aqueous electrolyte secondary battery using lithium-transition metal composite as anode material to reduce generation of gas preserved at high temperature and to inhibit expansion of cells and reduce deterioration of cell characteristic. CONSTITUTION: The secondary battery comprises (i) lithium-transition composite oxide which contains Ni and Mn as transition metals, has linear laminate structure as anode material and is added with additional fluorine; as cathode material, any material for absorption-discharging lithium element. The battery further comprises external housing(1) variable depending on elevation of inner pressure of the battery. The secondary battery is effective to reduce generation of gas where it is preserved under a condition of charging current at high temperature, and to reduce deterioration of cell characteristic caused by high temperature preservation.
    • 目的:提供一种使用锂 - 过渡金属复合材料作为阳极材料的非水电解质二次电池,以减少在高温下保存的气体的产生并抑制电池的膨胀并减少电池特性的劣化。 构成:二次电池包括(i)含有Ni和Mn作为过渡金属的锂 - 过渡复合氧化物,具有作为阳极材料的线性层压结构,并加入另外的氟; 作为阴极材料,用于吸收放电锂元素的任何材料。 电池还包括根据电池内部压力的升高而变化的外壳(1)。 二次电池在高温充电电流的条件下有效地减少其保存的气体的产生,并且降低由高温保存引起的电池特性的劣化。
