Electrochemically active CoO/Co₃O₄ co-existing microspheres with morphology-inherited porous particles is successfully synthesized via a simple solvothermal method. The as-prepared intermixed composite undergoes a monoxide CoO-preferred conversion reaction with an extremely enhanced capacity retention, ∼905 mA h g⁻¹ after 250 cycles for discharge state, which is 1.6 times higher than the conventional CoO_x-based anodes. Moreover, stable catalytic behavior of the electrocatalysts in Li-air cathodes of the given composites is also demonstrated. We believe that the extraordinarily enhanced electrode performance might be due to the novel pore-tempered microspheres packed with double electrochemically active centers of the CoO/Co₃O₄ composite effectively confine the detrimental volume exchange during the reversible cyclic reactions as well as the preserved multiple reactive sites for a reversible Li⁺ ⇄ LiO_x reaction, which is advantageous for advanced Li rechargeable battery.

通过简单的溶剂热法成功地合成了电化学活性的CoO / Co ₃ O ₄共存微球和形态学赋予的多孔颗粒。所制备的混合复合物经过一氧化碳CoO优选的转化反应，其容量保持率大大提高，放电状态250次循环后约905 mA h g ^-1，这是传统CoO _x基阳极的1.6倍。此外，还证明了给定复合材料在Li-空气阴极中电催化剂的稳定催化行为。我们认为，电极性能的特别提高可能是由于新型的孔回火微球中充满了CoO / Co的双重电化学活性中心₃ O ₄复合材料有效地限制了可逆循环反应过程中有害的体积交换以及可逆的Li ⁺ ⇄LiO _x反应的多个反应位的保留，这对于先进的可充电锂电池是有利的。
