〔産業上の利用分野〕
本発明は、導電性プラスチックを電極活物質とするプラ
スチック電池に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plastic battery using conductive plastic as an electrode active material.
プラスチック電池の電極活物質としては、その電池性能
からポリアニリン類やポリピロールが最も優れていると
考えられている。とりわけ、ポリアニリンはその優れた
自己放電特性から最良のものと考えられている。しかし
ながら、ポリアニリンは電気伝導度が小さく、高々数Ｓ
／ｃ１の値しかない。このため、ポリアニリンを電極活
物質に利用した電池では、充電電流値を大きくとれない
、大電流で放電できないといった問題があった。これら
の問題に対しては、電極面積を大きくしたり、活物質の
内部に集電体を配するといった対策が打たれているし、
活物質自身の電気伝導度を高める目的で導電性のカーボ
ンを混合して成形することも行なわれている。Polyanilines and polypyrrole are considered to be the most excellent electrode active materials for plastic batteries due to their battery performance. In particular, polyaniline is considered the best because of its excellent self-discharge properties. However, polyaniline has low electrical conductivity, at most several S
There is only a value of /c1. For this reason, batteries using polyaniline as an electrode active material have problems such as not being able to maintain a large charging current value or being unable to discharge at a large current. Countermeasures have been taken to address these problems, such as increasing the electrode area and placing a current collector inside the active material.
In order to increase the electrical conductivity of the active material itself, conductive carbon is also mixed and molded.
しかし、これらの対策のうち、活物質の内部や片面に集
電体を設ける工夫は、小型の電池に対しては有効である
が、大型の電池（例えば、自動車用バッテリーなど）で
は重量増、コスト増につながり、採用することはできな
い。このため、電極面積に比べて小さな集電極を設けて
いかに効率良く電気の出し入れをするかが、プラスチッ
ク電池の性能を左右することになる。However, among these measures, the idea of providing a current collector inside or on one side of the active material is effective for small batteries, but for large batteries (for example, automobile batteries), it increases weight, This will lead to increased costs and cannot be adopted. For this reason, the performance of plastic batteries is determined by how efficiently electricity can be taken in and out by providing a collector electrode that is smaller than the electrode area.
導電性プラスチックを電極活物質とするプラスチック電
池は、内部抵抗が既存の鉛蓄電池やニッケルカドミウム
電池に比べて高い。Plastic batteries that use conductive plastic as the electrode active material have higher internal resistance than existing lead-acid batteries and nickel-cadmium batteries.
これは、前記したよう−こ活物質自身の電気伝導度が低
いことと、活物質と集電体との間の密着性が良くないた

凹凸が発生する。このため、活物質自身の電気伝導度が
低い問題を改善すべく前記したように小面積の集電極を
設けても、小面積の集電極の接触部分が抵抗となり、電
池の内部抵抗の増大につながる。This is due to the low electrical conductivity of the active material itself, as described above, and the contact resistance caused by poor adhesion between the active material and the current collector. That is, many conductive plastics including polyaniline have uneven surfaces. Even if a film-like polymer is synthesized by electrolytic oxidative polymerization using the shape of the electrode surface as a template, shrinkage occurs during the subsequent drying process, resulting in unevenness on the surface. Therefore, even if a small-area collector electrode is provided as described above to improve the problem of low electrical conductivity of the active material itself, the contact portion of the small-area collector electrode becomes a resistance, which increases the internal resistance of the battery. Connect.
従って、本発明の目的は、前記したような問題を調和し
て解決し、プラスチック電池の持つ軽量、フレキシブル
といった特徴を活かしたまま、電池の内部抵抗の低減を
図ることにある。Therefore, an object of the present invention is to harmoniously solve the above-mentioned problems and reduce the internal resistance of a plastic battery while taking advantage of its characteristics such as light weight and flexibility.

It is characterized by being vapor-deposited.

A conductive substance is deposited on the contact area or contact surface with a current collector (made of conductive material such as stainless steel) to reduce internal resistance of the battery caused by contact resistance due to unevenness on the surface of the electrode active material. It is something.

ものではない。Various configurations can be considered for this purpose, but for example, a conductive substance such as metal, metal oxide, conductive carbon, etc. is steamed on the contact surface part or the entire surface of the electrode active material side that contacts the collector electrode. Alternatively, two sheets of electrode active material on which a conductive material is deposited in this manner can be configured in a layered manner such that the conductive material is in contact with the collector electrode.
