一般描述
Lithium bis(trimethylsilyl)amide also known as lithium hexamethyldisilazide (LiHMDS) is a non-nucleophilic strong base. It exhibits ionic conductivity and is widely used as a lithium source and additive in electrolyte formulations for lithium-ion batteries.
应用
Lithium bis(trimethylsilyl)amide can be used:
- As an electrolyte additive for non-aqueous lithium metal batteries. LiHMDS acts as a scavenger for hydrofluoric acid and forms an electrochemical robust cathode|electrolyte interphase (CEI) and suppresses the side reactions with the electrolyte solution.
- As a lithium precursor for atomic layer deposition(ALD) of textured Li4Ti5O12 as anode material for Li-ion ultrafast charging thin-film batteries. It enables the controlled delivery of lithium atoms into the deposition process, leading to the growth of thin films with precise thickness and composition.
- As a precursor to fabricate in situ lithiated quinone cathode as high-capacity organic electrode material for all-solid-state thin-film battery setup.
