Protective electrode/electrolyte interphases for high energy lithium-ion batteries with p-toluenesulfonyl fluoride electrolyte additive

Journal of Energy Chemistry, 2021
High energy density lithium-ion batteries using Ni-rich cathode (such as LiNi0.6Co0.2Mn0.2O2) suffer from severe capacity decay. P-toluenesulfonyl fluoride (pTSF) has been investigated as a novel film-forming electrolyte additive to enhance the cycling ...

Improving blue quantum dot light-emitting diodes by a lithium fluoride interfacial layer

Applied Physics Letters, 2019
Unlike green and red quantum dot light-emitting diodes (QLEDs), electron injection is not sufficient for blue QLEDs due to a higher potential barrier at the quantum dot (QD)/ZnO interface.

Periodic photonic structures in lithium fluoride

SPIE Proceedings, 2011
Lithium Fluoride (LiF) presents interesting optical properties and it has been proposed as an active optical material for colour centre (CC) lasers and amplifiers. The use of a grating to reduce the laser threshold and to narrow the line-width has also been demonstrated.
