摘　　要：本研究设计了一种基于Fe-FeCl_(3)体系的变种空气电池,通过开路电压、恒电流放电等测试,比较了其与传统商用Fe-空气电池的放电性能。结果表明,Fe-FeCl_(3)电池的开路电压更高,放电潜力更大;且在任一恒定放电电流下Fe-FeCl_(3)均拥有更高的放电电压,其放电做功能力显著优于商用Fe-空气电池;该电池的放电效率随放电电流的升高而增加,在放电电流超过10mA/cm^(2)时,放电效率均超过80%,Fe-FeCl_(3)变种空气电池是一种前景广阔的化学电源。An improved metal-air battery based on Fe-FeCl_(3) was designed in this study.Its discharge performance was measured and compared with commercial iron-air battery by using open-circuit voltage testing and constant current discharge testing.The results showed that the open-circuit voltage of Fe-FeCl_(3) battery was much higher than that of commercial ironair battery,indicating a bigger discharge capability of Fe-FeCl_(3) battery.The Fe-FeCl_(3) battery also exhibited bigger discharge voltages under every constant discharge current compared to the commercial iron-air battery.The discharge efficiency of Fe-FeCl_(3) battery increased with discharge current,and exceeded 80%when discharge current reaching 10 mA/cm^(2).The Fe-FeCl_(3) improved metal-air battery is a promising electrochemical power source.
