摘要

Nickel chloride is a promising cathode material for high-power thermal batteries due to its high theoretical capacity, high discharge current density, and high electrode potential. Nevertheless, its substandard electrical conductivity, elevated-temperature melting properties, and electrolyte interface instability considerably constrain its practical applications. In this paper, NiCl1.6Br0.4 with high electrical conductivity and high specific capacity was prepared through comparative experiments, and the merits of BN over MgO for LiB/NiCl1.6Br0.4 thermal battery system were demonstrated by analyzing the difference between electrochemical performance and melting leaching phenomenon. The LiB/BN-E/NiCl2-xBrx thermal battery system demonstrates optimal discharge performance at 500 °C, achieving a specific capacity of 319 mAh g−1, a specific energy of 744 Wh kg−1, and a specific power of 7.0 kW kg−1 under a discharge condition of 0.2 A cm−2. The LiB/BN-E/NiCl2-xBrx thermal battery system has application prospects in high-energy thermal batteries.
