Halocarbon fluorinated esters provide unique benefits notavailable in conventional non-fluorinated esters:
Performance over a wider temperature range (enabling lowertemperature performance)
Improved capacity retention
Enhanced oxidative stability, allowing use at high voltageranges (4.2V-5.0V)
Some fluorinated esters can reduce flammability
Improved solubility with certain lithium salts (eg. LiBOB)
