摘要
对不同电解质和正负极材料的锂系热电池电化学体系性能进行了比较。研究发现:三元全锂电解质(LiF-LiCl-LiBr)因离子电导率高,在工作温度超过450℃时放电性能明显优于其他电解质;CoS2内阻低,放电电压精度和实际利用率均优于FeS2;LiB合金理论电容量高、电极电位低,利用率可大于90%,远高于LiSi合金。
The performances of the lithium thermal batteries with different electrolyte, anode and cathode were compared in this paper. The results showed that the LiF-LiC1-LiBr was superior to other electrolyte when operated at temperatures higher than 450 ℃ due to its relative higher ionic conductivity. CoS2 cathode was better than FeS2 with regard to internal resistance, discharge potential and the capacity available. LiB alloy anode exc2lled LiSi in terms of high theoretical capacity, low reduction/oxidation potential and more than 90% of utilization rate.
