Can lithium fluoride store hydrogen

Does lithium fluoride monolayer adsorb hydrogen?

This work presents the first report on the hydrogen storage properties by utilizing lithium fluoride (LiF) monolayer. LiF in zinc blende and monolayer hexagonal phases are found to be stable with indirect bandgaps. Adsorption energies of hydrogen molecules are found in the range of −0.15 to 0.64 eV/H 2 on the LiF surface.

What makes lithium fluoride unique?

Lithium fluoride (LiF) stands out due to its high lithiophobicity and anodic stability (>6.0 V versus Li/Li +) 6; however, simultaneously tailoring LiF-rich SEI/CEI interphases is a difficult task.

Is hydrogen fluoride a risk for a Li-ion battery fire?

The release of hydrogen fluoride from a Li-ion battery fire can therefore be a severe risk and an even greater risk in confined or semi-confined spaces. This is the first paper to report measurements of POF 3, 15–22 mg/Wh, from commercial Li-ion battery cells undergoing abuse.

How much hydrogen fluoride can a battery generate?

The results have been validated using two independent measurement techniques and show that large amounts of hydrogen fluoride (HF) may be generated, ranging between 20 and 200 mg/Wh of nominal battery energy capacity. In addition, 15–22 mg/Wh of another potentially toxic gas, phosphoryl fluoride (POF 3), was measured in some of the fire tests.

Do lithium-ion batteries emit HF during a fire?

Our quantitative study of the emission gases from Li-ion battery fires covers a wide range of battery types. We found that commercial lithium-ion batteries can emit considerable amounts of HF during a fire and that the emission rates vary for different types of batteries and SOC levels.

Can LIF nanosheets be used for hydrogen storage?

Our outcomes subsequently supports the potential application in hydrogen storage. The storage capacity (wt%) for H 2 molecules on the LiF nanosheet is found to be increased from 0.85% to 13.45% for the H 2 concentration of 1–18 molecules.
