LHS 是一种非自燃性强碱，作为金属化剂广泛用于有机合成。这种试剂的主要优点包括可改善去质子化反应中的选择性，并提高热稳定性。它可作为碱用于生成烯醇，以便制备内酯前体。(1) 《有机化学杂志》(J.Org.Chem.)1993 年，58，7304。(2) 《合成有机化学快报》(Synlett) 1993 年，507。(3) 《四面体》(Tetrahedron) 1994 年，50，9061。LHS 以 THF 溶液的形式提供，因此非常易于从运输容器转移到反应器或储存容器。LHS 是一种比二异丙基氨基锂 (LDA) 更稳定的碱。
Appearance: White, free-flowing crystals; occasional dark specks may be present.* Meets or exceeds ACS Reagent Grade Specifications * Occasional dark particles may be visible and scattered in the product. The particles have no detectable effect on product purity and will not be cause for rejection. Application: ACS grade used for Electrolyte for dry cells used at low temperatures, catalyst in certain oxidation reactions, solubilizer for polyamides and cellulose when used with amide solvents, chlorinating agent for steroid substrates.
Appearance: White powder Application: Additive in specialty glasses and low-expansion ceramics, analytical agent.

Lectro® Max Powder (SLMP®) 提供了一种独立的锂来源，从而为阳极和阴极材料带来了更多选择，使新一代锂离子电池得以成为现实。以稳定化粉末形式将锂引入阳极主体材料（如硅 [Si] 基和锡 [Sn] 基材料）中，可以形成一个锂离子系统，从而生产出能量和锂利用效率更高的电池。使用对过充电具有更高耐受性并且可能成本更低的非锂成分（如锰、钒或其他金属氧化物和金属氟化物）提供阴极，可以生产出更安全、更便宜的电池。这些材料结合使用，可能会将现有锂离子电池的能量密度提高一倍。 Lectro® Max Powder (SLMP®) 可以用于替代薄锂箔应用，以及在核聚变研究设备中改善等离子性能。
Appearance: An odorless, white powder. Lithium carbonate based admixture. Application: LifeTech ultrafines is the finest of the LifeTech grades of lithium carbonate available from Livent. Because of its fine particle size and narrow particle size distribution, this product has been chosen as the grade of choice where reactivity and performance are based on the surface area of the lithium carbonate particles providing controllable, uniform and predictable rates of reaction. Since it is the finest of the grades, it is also the most reactive in these situations. If a slower reaction is desired, the other LifeTech grades should be evaluated in use. LifeTech ultrafines is a chemical admixture that can be used to adjust and accelerate the setting time of cementitious systems such as high-alumina cements (HAC) and aluminaportland cement blends. The unique properties of LifeTech ultrafines have made this product the grade of lithium carbonate of choice in a number of other applications such as in manufacture of ceramics, welding rods, refractory materials, and specialty glasses.
Appearance: An odorless, white powder. Lithium carbonate based admixture. Application: LifeTech superfines is the medium of the LifeTech grades of lithium carbonate available from Livent. Because of its fine particle size and narrow particle size distribution, this product has been chosen as the grade of choice where reactivity and performance are based on the surface area of the lithium carbonate particles providing controllable, uniform and predictable rates of reaction. Since it is the medium of the grades, it is not as reactive as the ultrafines, but more reactive than the fines. If a different reaction rate is desired, the other LifeTech grades should be evaluated in use. LifeTech superfines is a chemical admixture that can be used to adjust and accelerate the setting time of cementitious systems such as high-alumina cements (HAC) and aluminaportland cement blends.
