Research Abstract |
We have studied secondary air-battery consists of Zn (negative electrode) and activated charcoal (positive electrode). Characteristic point of the present battery is to adopt unique activated charcoal made from saw-dust fabricated under high-pressure and high temperature, which can play a role as adsorption electrode of oxygen ion (OH-), by which we can realize rechargeable carbon air-battery. Basic property of the new battery is following: typical cell-voltage after charging (Voc) ranges from 1.5V to 1.8V with high capacity / kg of 15-20 Ah/kg. This value is equally comparable with practical Pb- battery. A charge-discharge efficiency of the carbon air-battery reveals excellent value exceeding 80%, and this battery has high potential as practical new carbon air-batter in future.
