The scientists found that combining multiple components into a new electrolyte results in the formation of strong and kinetically active interphase boundaries at both the cathode and anode. These interfaces enriched with LiF and Li3PO4 have high mechanical stability and improved ionic conductivity.
As a result, it prevents cathode surface degradation, suppresses undesirable interfacial reactions, accelerates reaction kinetics, and reduces lithium dendrite formation even at extremely high current densities. Thus, a high-performance Li-ion battery with a voltage of 4.6 V is obtained.
The results showed that the capacity retention in this electrolyte was up to 73.2% even during fast charging for 1000 cycles.
