摘要
本文简要分析了传统热电池电极及电解质制备工艺存在的问题,采用涂布工艺分别制备了热电池正极和电解质薄膜,通过形貌分析、高温电性能测试等表征手段验证了涂布工艺制备热电池正极及薄膜电解质的可行性和合理性。结果表明:该工艺技术的应用,不仅可保留热电池材料性质,还可以降低电解质与电极间的界面内阻,提高电池的工作时间。因此,涂布技术的应用能够提高电极材料的利用率,对降低电池成本、推动热电池小型化发展具有重要意义。
The feasibility and rationality of preparing the positive electrode and electrolyte membrane of thermal battery by coating process are verified by means of morphology analysis and high-temperature electrical performance test. The results show that the application of this technology can not only preserve the material properties of the thermal battery, but also reduce the interfacial internal resistance between electrolyte and electrode and improve the working time of the battery. Therefore, the application of coating technology can improve the utilization rate of electrode materials,which is of great significance to reduce battery costs and promote the miniaturization of thermal batteries.
