摘要
合成了Cu3V2O8(CVO)作为正极活性物质,并通过X射线衍射光谱法(XRD)对CVO进行表征;制备了Li NO3-KNO3-Ca(NO3)2电解质,并测试了其熔点。通过对Li-Si/Li NO3-KNO3-Ca(NO3)2/CVO单体热电池进行恒流放电测试,探究了导电剂CNT、电解质在正极材料中的添加量以及温度对放电性能的影响。结果表明,在正极中,CNT与电解质的适宜质量分数分别为5%、35%。单体电池的放电性能受温度的影响比较大,温度在250~280℃时,单体电池有较好的放电效果。
Cu3V2O8 (CVO) was synthesized and used as cathode active material, and was analyzed by XRD. LiNO3-KNO3-Ca(NO3)2 electrolyte was prepared, and it's melting point was tested. The influence of conductor CNT and electrolyte additive amount and the influence of temperature on discharge performance by Li-Si/LiNO3-KNO3-Ca (NO3)ICVO single cell constant current discharge experiments were studied. The discharge results show that the propriate additive qualities of CNT and electrolyte in cathode are 5% and 35%. The single cell discharge performance has a great dependent on temperature, with better result within a temperature range of 250-280 ℃.
