Self-terminated oligomers with hyper branched architecture,also known as STOBA are combined with lithium ion battery cathode materials by two different ways:mechanical blending and surface *** comparative electrochemical analyses of the assembled coin cells demonstrates that for the mechanical blending combined materials no blocking effects are observed at high temperature *** the surface coating ones,STOBA has slightly impact on the cell performance at room temperature,but when the ambient temperature exceedes the cross- linking temperature,large area of crosslinking will occur on the surface of the electrode materials,which prevents the lithium ion from extracting and *** a result,the battery totally loses charge-discharge capacity in the high rate discharge condition to ensure the safety when operating at high temperatures.

Experimental study of the effect of gas discharge on ionic liquid electrospray

Plasma Science and Technology 2024年第4期26卷 37-43页

Ionic liquid electrospray(ILE) in an atmospheric environment is often accompanied by the gas discharge phenomenon. It interferes with the normal operation of the electrospray and the measurement of experimental parameters. In this study, electrospray experiments were conducted on the ionic liquid EMI-BF4. The observations revealed that the operating modes of the ionic liquid depend on the voltage polarity at high voltages. Additionally, a correspondence between the operating mode of ILE and the current signal in the circuit was established. The shape of the liquid cone formed at the needle tip bore a striking resemblance to the plume of corona discharge, suggesting that the motion trajectory of electrons influenced the curvature of the liquid cone. Steamer theory provided a clear explanation for the change in curvature as the voltage increased.
