Fluorine-Free and Thermally Stable Lithium Salt Electrolyte for Lithium-Ion Batteries

Fluorine-Free and Thermally Stable Lithium Salt Electrolyte for Lithium-Ion Batteries

Updated

Lithium Bis(oxalate)borate (LiBOB, L0367) is a fluorine-free, thermally stable lithium salt for lithium-ion battery (LIB) electrolytes. It can be used as an alternative to traditional electrolytes or as an additive with traditional electrolytes. LiBOB is reported to suppress the deterioration of LIB cells and improve their cycle life. It also offers high SEI (solid electrolyte interphase) forming ability and good thermal stability. The use of LiBOB in lithium-ion electrolytes has been reported in several studies, covering its production and use as a conducting salt¹), its use as an additive in PP13TFSI-organic mixed electrolytes²), its use with Li-rich layered oxide cathode materials³), and its use in synergistic additives for high-voltage cathodes in half-cells and full-cells⁴).
