摘　　要：探索了Al2O3粘结剂在苛刻力学环境热电池中的应用,通过采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、孔隙分析仪对Al2O3的微观形貌和孔结构进行分析,发现Al2O3的微观结构为近球形颗粒,颗粒间搭建了丰富的多孔结构;电解质稳定性测试结果表明,Al2O3粘结剂对Li Cl-KCl共晶盐具有较好的保持能力,对应电解质的稳定性好;电性能及力学测试表明,基于Al2O3粘结剂制备热电池的电性能满足技术需求,耐苛刻力学性能优于MgO,Al2O3非常有希望替代MgO作为热电池粘结剂材料。The application research of Al2O3 binder in strict mechanics thermal batteries was explored. The microstructure and pore structure of Al2O3 were analyzed by SEM, TEM and porosity analyzer, and the results show that the microstructure of Al2O3 is nearly spherical particle and the porosity is built by connection between particles. The test results of electrolyte stability show that the holding capacity of LiCI-KCI in Al2O3 is obviously better, so the stability of corresponding electrolyte is better. The test results of electric and mechanic properties show that the electric properties of batteries made with Al2O3 satisfy the requirement, the resistance to strict mechanic properties of the batteries are better than that of batteries made with MgO. The replacement of MgO by Al2O3 as binder in thermal batteries is extremely promising.
