Challenges for Safe Electrolytes Applied in Lithium Ion Cells—A
· Triphenylphosphate TPP and tributylphosphate TBP were used as flame retardants FRs to provide superior thermal safety in lithium ion cells at the fully charged state The specific discharge capacity of the cell with 5% of TPP and 5% of TBP was equal to 120 100 mAh g −1 after 150 cycles respectively at C/20
