Lithium bis (oxalato) borate , or LiBOB for short , is an inorganic - chemical compound of lithium from the group of borates . LiBOB is a white solid in powder form that is soluble in anhydrous solvents such as propylene carbonate, it slowly disintegrates on contact with water.
Lithium bis (oxalato) borate is used in the electrolytes of lithium-ion batteries and can replace fluorine-containing substances such as lithium tetrafluoroborate or lithium hexafluorophosphate in this area of application . The replacement as an electrolyte in lithium-ion batteries offers the advantage of avoiding the formation of hydrogen fluoride (HF) as a highly corrosive decomposition product in the event of damage and fire on the battery.
