従来例の構成とその問題点

。Conventional structure and its problems Photoelectric batteries that use activated carbon as polarizable electrodes are generally made of the same activated carbon for both the positive and negative electrodes, and dissolve lithium perchlorate, ammonium perchlorate, etc. as electrolytic waves. porous resin cloth or glass fiber cloth with excellent oxidation resistance is used as a separator.
この種の電池は、主に活性炭表面の電気工Ｎ層における
電荷チャージを光放電に利用するものである。したがっ
て、電気二重層を形成する活性炭の有効表面積や導電性
、さらには集電体及び活性炭の収納ケースとの接触抵抗
々どが問題となる。This type of battery mainly utilizes charge in the electrician N layer on the surface of activated carbon for photodischarge. Therefore, the effective surface area and conductivity of the activated carbon that forms the electric double layer, as well as the contact resistance between the current collector and the activated carbon storage case, etc., pose problems.
この中で、とくに集電体の役目は、電池の内部抵抗を低

ものである。Among these, the role of the current collector is to lower the internal resistance of the battery and stabilize the long-term charge/discharge cycle characteristics.
この集電体の効果をさらに向上させるために、集電体を

ｆ［出さぞ、その露出部をケースにスポット浴接したも
のなどがある。In order to further improve the effect of this current collector, it is common to weld the current collector to the case. The methods include spraying aluminum metal onto activated carbon fiber cloth to provide an aluminum layer on one side of the activated carbon, and spot welding it to the case, or scraping off a part of the activated carbon of an activated carbon molded body with a built-in aluminum lath plate. Take the lath board -j
There are some cases where the exposed part is spot-contacted to the case.

は強くなるが、活性炭の一部を欠損するため電気容量が
小さくなぁという欠点があった。The former, thermally sprayed aluminum, has excellent conductivity, but is expensive, and when welded to the case, the welding strength is not necessarily strong, and the activated carbon layer peels off more easily than the case. In the latter case, if a part of the activated carbon was removed and spot welded, the strength of the bath contact with the case would be stronger, but the disadvantage was that the electric capacity would be small because part of the activated carbon would be missing.
