MOSi - Use of trialkylsiloxy-based metal complexes as an additive in lithium-ion batteries

总结
The invention "M (OSiR3) x based additives for LIB" describes trialkylsiloxy metal complexes as electrolyte additives for lithium ion batteries (LIB). These not only serve as HF catchers, but also form a s.g. SEI layer on the electrodes. The cathode layer ensures better cycle stability at increased working voltage and energy density.
技术优势
TMS Complex of titanium, aluminum or boron for high voltage cells
Suppress the capacity fade at potential of up to 4.6 V vs. Li/Li+
LIB full-cells show more than a twofold cycle life compared to the standard electrolyte
Increase the energy efficiency of LiNi1/3Co1/3Mn1/3O2
Reduce the presence of electrolyte decomposition products in the electrolyte, mainly LiF
Hindering the formation of a thick resistive surface film
Ti and Al Complexes are actively incorporated into the formed CEI layer
All additives can help to decrease the interfacial resistance
技术应用
The addition of the M(TMS)x based additives lowers the charge transfer impedance during prolonged cycling. MOSi leads to lithium ion batteries with enhanced anti fading performance.
