Application

Lithium Fluoride (LiF) can be used as an additive in electrolytes for lithium-ion batteries to enhance thermal stability and overall battery performance. Applied as a thin film on electrodes to improve their stability and lifespan by preventing degradation during cycling. LiF is a crucial component of the anode interface film due to its high-modulus shell, which can prevent LixSi pulverization, and its high chemical stability, which effectively suppresses side reactions at the interface. LiF is used in nuclear reactors and radiation detectors due to its low neutron cross-section and ability to capture neutrons, making it suitable for neutron shielding and detection.[1]

Lithium fluoride (LiF) can be used as a sintering aid that facilitates the etching of spinel particles for the degradation of magnesium aluminum spinel.[2] It can be used in the preparation of carbon-iron LiF nanocomposite based electrode materials for lithium-ion batteries.[3] 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.[4]
