Study on Discharge Performance of LiV3O8/NiF2 Cathode Materials for Thermal Batteries
Lithium vanadate cathode material was synthesized by sol-gel mothod,and mixed with nickel fluoride in different proportions,the single battery was prepared by powder compression process,and the optimal proportion of LiV3O8/NiF2 cathode material was determined.The experimental results showed that when the single cell battery was discharged at a constant current of 100 mA·cm-2,the discharge performance of the single battery with 9∶1 was the best,and the optimal addition amounts of electrolyte and conductive agent in the cathode were 15%and 15%,respectively.The specific capacity was 140 mA·h·g-1 when the initial discharge voltage was 2.565 4 V and the cutoff voltage was 2 V.
