摘要

研制以改进的氟化石墨为正极、锂为负极的6. 0 Ah圆柱形锂/氟化碳(Li/CF_x)电池。通过过放、短路、针刺和挤压等安全实验,对Li/CF_x电池进行安全性能测试。电池以0. 20 C倍率过放至-2. 00 V,没有鼓胀、漏液、爆炸和起火,表面的最大温升不超过78℃;电池经短路实验,没有出现鼓胀、漏液、爆炸和起火,表面的最大温升不超过95℃;电池经过针刺和挤压后,没有爆炸、起火,表面的最大温升不超过92℃。
        Lithium/fluorinated carbon( Li/CF_x) battery which was cylindrical with 6. 0 Ah was prepared with improved fluorinated graphite as cathode,lithium flake as anode. The safe performance of Li/CF_xbattery was characterized by over-discharging test,shortcircuit test,puncturing test and compressing test. When overcharged to-2. 00 V at 0. 20 C,battery had no bulge,leakage,explosion and fire phenomenon,the maximum temperature rise of the surface didn't exceed 78 ℃. After short-circuit experiment,there was no bulge,leakage,explosion and fire phenomenon,the maximum temperature rise of the surface did not exceed 95 ℃. When compressed and punctured,battery had no explosion and fire phenomenon,the maximum temperature rise of the surface did not exceed 92 ℃.
