従来、電極として導電性高分子材料を用いたプラスチッ
ク電池が知られている。このプラスチック電池は鉛電池
に比較して開路電圧が大きく〜しかも軽量であるため出
力密度が大きいという優れた利点を有する。Conventionally, plastic batteries using conductive polymer materials as electrodes are known. This plastic battery has an excellent advantage in that it has a higher open circuit voltage and is lighter in weight than a lead battery, and therefore has a higher output density.
ところで、導電性高分子は通常数百μｍの薄膜形状であ

った。By the way, conductive polymers are usually in the form of thin films of several hundred micrometers, so when used as electrodes for batteries used in transportation vehicles such as automobiles, their durability is limited due to external factors such as vibration and impact. It is said that there is a problem with this. but,
In such batteries, conductive polymer materials are used as electrodes as they are, so the electrode structure becomes a thin film structure, making it impossible to obtain sufficient mechanical strength.For example, the electrode itself may become deformed. Another drawback is that the electrodes are easily damaged when connected to an external circuit.
そこで、本件出願人は、導電性高分子材料をカ−ボン製

にショートする可能性を有している不具合がある。However, in such plastic electrodes, carbon fibers are knitted into a sheet to form a current collector with a thickness of about 0.4 m, and a tetraelectric polymer material is applied to this current collector by electrolytic polymerization. Since the electrode is formed by depositing a thin film, the capacitance of a single electrode is small, so it is necessary to stack multiple sheets to increase the capacitance. Therefore, when attaching lead wires of about 0.5 wφ to each of multiple current collectors, the work is not only complicated because the current collectors are thin, but also short-circuits occur when the electrodes are completed. There is a problem that has the potential to cause

性を排除することにある。Therefore, this invention was made to solve the above-mentioned problems, and a protruding piece is provided on each of a sheet-like first current collector made of a conductive material and a sheet-like second current collector made of aluminum. By forming a plurality of sheets and stacking them alternately without contact, and connecting the protruding pieces in one direction with corrugated strip lead plates, it is easy to attach the lead wires, and when the electrode is completed, The purpose is to eliminate the possibility of a short circuit.

Examples include those processed into a sheet shape so as to have the same properties. Note that since carbon fibers have conductivity, it is not necessary to coat them with other conductive materials; however, in order to further improve the conductivity, carbon fibers coated with other conductive materials may be used.
