Designed Fabrication of SnO/InO/C Electrochemical Sensors for Coolant Leakage Detection in Energy Storage Systems.

The liquid cooling system for lithium iron phosphate battery modules usually faces the threat of coolant leakage, which would dramatically affect the heat transfer performance, safety, and efficiency of the energy storage system. Herein, electrochemical sensing technology has been first employed to detect coolant leakage. Specifically, ethanol is selected as the additive reagent and used as the main tested substance, and the sensors indirectly identify the coolant leakage by detecting the leaked ethanol.

Designed Synthesis and Electrochemical Performance Regulation of the Hierarchical Hollow Structure CuS/CuS/NC Anode for Hybrid Supercapacitors.

Copper-based compounds have attracted increasing attention as electrode materials for rechargeable devices, but their poor conductivity and insufficient stability inhibit their further development. Herein, an effective method has been proposed to improve the electrochemical properties of the copper-based electrodes by coating carbon materials and generating unique micro/nanostructures. The prepared CuS/CuS/NC with hierarchical hollow structure possesses excellent electrochemical performance, attributing to the composition and structure optimization.
