It is costly to synthesize cathode materials through the solid reaction of raw materials at relatively high temperatures due to its high energy consumption. Here, we use LiCoO₂ as a model material to demonstrate a novel method for synthesizing cathode materials within 120 s at temperatures as low as 260 °C under an AC electric field. The influence of the current density, current retention time, and synthesis atmosphere on the prepared LiCoO₂ materials was systematically investigated. The results indicate that the acceleration of the synthesis process between Co₂O₃ and Li₂CO₃ is due to the introduction of oxygen vacancies into the reaction system under a threshold electric field. The obtained LiCoO₂ exhibits the same electrochemical performance as that of LiCoO₂ synthesized via the conventional thermal reaction method. The proposed synthesis method could provide a cost-effective pathway to synthesize different cathode materials.

通过原料在较高温度下进行固相反应合成正极材料，其能耗较高，成本较高。在这里，我们使用 LiCoO ₂作为模型材料来展示一种在交流电场下在低至 260 °C 的温度下在 120 秒内合成正极材料的新方法。系统地研究了电流密度、电流保留时间和合成气氛对制备的LiCoO _{2材料的影响。结果表明，Co 2} O ₃和Li ₂ CO ₃之间的合成过程的加速这是由于在阈值电场下将氧空位引入反应体系。所得LiCoO ₂表现出与通过常规热反应法合成的LiCoO ₂相同的电化学性能。所提出的合成方法可以为合成不同的阴极材料提供具有成本效益的途径。
