Application

Lithium fluoride (LiF) can be used as a sintering aid that facilitates the etching of spinel particles for the degradation of magnesium aluminum spinel. It can be used in the preparation of carbon-iron LiF nanocomposite based electrode materials for lithium-ion batteries. It can also form thin interlayers on the counter electrode to enhance the fill factor and stabilize the high open-circuit voltages for polymer solar cells.
