There are many challenges for the Static lithium polysulfide semiliquid battery in its commercial application, such as poor stability of the cathode material and further amplification of the lithium polysulfide shuttle effect. Therefore, this manuscript introduced a new type of Pt₃ composite material as cathode working electrode based on the principle of volcanic catalytic curve. Through symmetric battery test, CV, polarization curves and impedance test, it was found that Pt₃[email protected] composite material had good catalytic activity of lithium polysulfide to improve electrochemical kinetics. When the catholyte was Li₂S₈ and the charge-discharge voltage range was 1.8~2.6 V, the capacity maintained at approximately 550 mAh g⁻¹, and the coulombic efficiency maintained at approximately 95% after 100 cycles at a current rate of 0.5 mA cm⁻². The Pt₃[email protected] composite material is a potential cathode material with the specific capacity and long cycling stability of the static lithium polysulfide semiliquid battery.
