A novel high safe trimethylsilyl substituted propylene carbonate(TMSPC)was designed and synthesized as electrolyte for lithium-ion batteries.Its physicochemical properties
such as thermal property
ionic conductivity
electrochemical window
and flammability were investigated in detail.With adding 30%(vol) TMSPC into the electrolyte of 1 mol·L-1 LiPF6/EC:DEC(1:1
vol.ratio)
the propagation rate could be reduced significantly.LiFeO4/Li half cell test showed that the cycling performance could be improved with 30%(vol) TMSPC additions in the electrolyte of 1 mol·L-1 LiPF6/EC:DEC(1:1
vol.ratio)
exhibiting a specific capacity of 109 mA·h·g-1 and a capacity retention of 87% as compared with 106 mA·h·g-1 and 81% for the base electrolyte at 0.2 C rate after 110 cycles.
