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.

我们研究了二次空气池由Zn（负电极）和活化的木炭（正电极）组成。当前电池的特征点是采用由在高压和高温下制造的锯子制成的独特活性木炭，可以作为氧气（OH-）的吸附电极发挥作用，我们可以通过它来实现可充电的可充电碳空气气口。新电池的基本属性如下：充电后典型的单元电压（VOC）范围从1.5V到1.8V，高容量 /千克为15-20 AH / kg。该值与实用的PB-电池同样可比。碳空气电池的充电效率显示出超过80％的出色价值，并且该电池在将来具有很高的实用新碳空气爆炸的潜力。
