Description of the Related Art In recent years, with the rapid miniaturization and diversification of consumer mobile phones, portable electronic devices, portable information terminals, and the like, small, lightweight, and high-energy densities are required for batteries as power sources. There is a strong demand for the development of a secondary battery that can repeatedly charge and discharge for a longer period. Among them, non-aqueous electrolyte secondary batteries such as lithium ion secondary batteries are the most promising secondary batteries that meet these requirements, compared to lead batteries and nickel cadmium batteries that use aqueous electrolytes. Research is being conducted.

But when using carbonaceous materials,
There is an advantage that a battery having a long cycle life can be obtained and safety is high.

There is a disadvantage that the voltage loss due to the ohmic loss at the connection between the batteries increases. In contrast, Japanese Patent Laid-Open No. 4-34
No. 1766 describes that a battery capable of reducing the voltage loss can be obtained by using a bipolar electrode having positive and negative electrode active materials for one current collector.

Each active material was applied so that the positive electrode active material was in contact with aluminum and the negative electrode active material was in contact with copper. This is because, for example, when aluminum used as a positive electrode current collector is used as a current collector for a bipolar electrode as it is, it reacts with lithium of the negative electrode at a contact portion with the negative electrode active material and alloys as Li-Al, thereby functioning as a battery. This is because there is a problem that it will not be performed. On the other hand, when copper, which is a general negative electrode current collector, is used, copper is about 3.4 V (vs. Li / Li + ).
This is because they cannot be used for the positive electrode because they are oxidized and dissolved at the same time. Therefore, using a bimetal of aluminum and copper, the positive electrode active material on the aluminum side,
A negative electrode active material was provided on the copper side to form an electrode plate.
