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.

我们研究了由锌(负极)和活性碳(正极)组成的二次空气电池。本电池的特点是采用了独特的由高温高压锯末制成的活性碳，可以作为氧离子(OH-)的吸附电极，从而实现可充电碳空气电池。新电池的基本性能如下：典型的电池充电后电压(VOC)为1.5V~1.8V，大容量/kg为15~20ah/kg。这一数值与实际的铅蓄电池相当。碳空气电池的充放电效率达到80%以上，具有很高的应用前景。
