li-rich layered oxide cathodes have received considerable attention because of the high operating potential and specific capacity. However, the structural instability and parasitic reactions at high potential cause severe degradation of the electrochemical performance. In our studies, the cycling stability of li_(1.14)Ni_(0.133)Co_(0.133)Mn_(0.544)O_(2) cathode is improved with liPO_(2)F_(2) electrolyte additive. After 500 cycles, the capacity retention is increased from 53.6% to 85% at 3 C by liPO_(2)F_(2) modification. This performance is mainly attributed to the enhanced interfacial stability of the li-rich cathode. Based on systematic characterization, liPO_(2)F_(2) additive was found to promote a stable interface film on the cathode surface during the cycling and mitigates the interfacial side reactions. This study provides new insights for improving high-potential li-rich layered oxide batteries.

Oil-water interface layers dilatation rheological properties have been measured with the liquid-liquid interface film pressure measurement apparatus, which was based on the principles of Langmuir film balance. Experimental results show that it is possible to form the interface-associated material caused by the attraction of the dispersion forces at the pure alkane-water interface. The type of material is sensitive to the interfacial pressure. Under the influence of the interfacial pressure, the stability of the interface associated materials decreases with the increase of the number of alkane carbons.
