This battery was invented in 1866 by Georges Leclanché (1839-82) of France. It is a wet cell battery with the following structure, using zinc Zn as the negative electrode active material, manganese dioxide MnO2 as the positive electrode active material, and a 20% aqueous solution of ammonium chloride NH4Cl as the electrolyte. Zn| NH4Cl | MnO2 |C In Japan, in 1885, Senzo Yai (1863-1927) created a dry cell with the same structure as the Leclanché cell and exhibited it at the World's Fair held in the United States in 1892.

1866年フランスのルクランシェGeorges Leclanché(1839―82)によって発明された電池。負極活物質に亜鉛Znを、正極活物質に二酸化マンガンMnO2を、電解液に20%塩化アンモニウムNH4Cl水溶液を用いた次の構成の湿電池である。 Zn|NH4Cl|MnO2|C わが国では、1885年に屋井先蔵(1863―1927)がこのルクランシェ電池と同じ構成の乾電池を作製し、1892年にアメリカで開かれた万国博覧会に出品している。 [浅野 満] 『橋本尚著『電池の科学――生物電池から太陽電池まで』(1987・講談社)』▽『電気化学会編『電気化学便覧』(2000・丸善)』▽『電池便覧編集委員会編『電池便覧』(2001・丸善)』▽『小久見善八・池田宏之助編著『はじめての二次電池技術』(2001・工業調査会)』 [参照項目] | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
