    Abstract: To increase the conductivity and electric capacity of an electrode which includes active material particles and the like and is used in a battery, a graphene net including 1 to 100 graphene sheets is used instead of a conventionally used conduction auxiliary agent and binder. The graphene net which has a two-dimensional expansion and a three-dimensional structure is more likely to touch active material particles or another conduction auxiliary agent, thereby increasing the conductivity and the bonding strength between active material particles. This graphene net is obtained by mixing graphene oxide and active material particles and then heating the mixture in a vacuum or a reducing atmosphere.

    Abstract: In the case where a secondary battery is repetitively curved, portions which tend to cause deterioration such as crack or breakage are, for example, a positive electrode tab and a negative electrode tab. This is because these portions are narrow projected portions, and tend to have low mechanical strength against repetitive curving in some cases. In view of the above, the positive electrode tab and the negative electrode tab are provided in portions relatively less affected by curving. More specifically, secondary battery includes a positive electrode, a positive electrode lead electrically connected to the positive electrode, a negative electrode, a negative electrode lead electrically connected to the negative electrode, a separator, and an exterior body wrapping the positive electrode, the negative electrode, and the separator. The positive electrode, the separator, the negative electrode, and the exterior body can be curved in a first direction. The positive electrode lead and the negative electrode lead are drawn from opposite sides of the exterior body.

    Abstract translation: 在二次电池重复弯曲的情况下，倾向于引起诸如裂纹或断裂的劣化的部分例如是正极片和负电极片。 这是因为这些部分是窄的突出部分，并且在某些情况下倾向于具有低的反复弯曲的机械强度。 鉴于上述情况，正极片和负电极片以相对较少受弯曲影响的部分设置。 更具体地说，二次电池包括正极，与正极电连接的正极引线，负极，与负极电连接的负极引线，隔膜和包围正极的外部主体，负极 电极和分离器。 正极，隔板，负极和外部主体可以在第一方向上弯曲。 正极引线和负极引线从外部主体的相对侧拉出。
