MOSi - Use of trialkylsiloxy-based metal complexes as an additive in lithium-ion batteries
- Summary
- 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.
- Technology Benefits
- 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
- Technology Application
- 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.
