报道了一种新型可充电Li/O-2电池。它包括夹有薄锂金属箔阳极的锂离子导电有机聚合物电解质膜和薄碳复合电极，在该薄碳复合电极上，从环境中获取的电活性阴极材料氧在放电时被还原以产生电能。它的特点是采用全固态设计，将电极和电解液层压在一起，形成200至300微米厚的电池单元。放电过程中的整个电池反应似乎是2Li+O-2-->；Li2O2。它的开路电压约为3V，负载电压范围在2至2.8V之间，具体取决于负载电阻。该电池可以使用钴酞菁催化的碳电极以良好的库仑效率进行充电。
A novel rechargeable Li/O-2 battery is reported. It comprises a Li+ conductive organic polymer electrolyte membrane sandwiched by a thin Li metal foil anode, and a thin carbon composite electrode on which oxygen, the electroactive cathode material, accessed from the environment, is reduced during discharge to generate electric power. It features an all solid state design in which electrode and electrolyte layers are laminated to form a 200 to 300 mu m thick battery cell. The overall cell reaction during discharge appears to be 2Li + O-2 --> Li2O2. It has an open-circuit voltage of about 3 V, and a load voltage that spans between 2 and 2.8 V depending upon the load resistance. The cell can be recharged with good coulombic efficiency using a cobalt phthalocyanine catalyzed carbon electrode.
