General description

Magnesium Chloride hydrate, is a white crystalline substance with properties of a Lewis acid. It dissolves in water. It is also slightly soluble in acetone and pyridine. Anhydrous MgCl2 is commonly used as a precursor in the production of metallic magnesium. OurMagnesium Chloride hydrate is suitable molten salt to prepare different types of eutectic mixtures due to its high operation temperature for thermal energy storage (TES) materials and heat transfer fluids (HTFs) for next-generation concentrating solar power (CSP) systems.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product belongs to an Enabling category, and is a key component in greener battery technologies due to its abundance and lower environmental impact. It enhances battery safety and stability by reducing the risk of flammability and dendrite formation. Additionally, innovative electrolytes using magnesium chloride improve the efficiency and longevity of magnesium-ion batteries. Click here for more information.

Application

Our >99.99% Magnesium Chloride hydrate, with low impurities, and solubility in water, is suitable for various applications. Example:Magnesium Chloride, is well-suited for use in magnesium batteries, particularly in the production of MgTFSI2/MgCl2 (DME) electrolyte solutions. These solutions have been found to effectively dissolve a substantial amount of magnesium chloride, resulting in enhanced electrochemical performance, notably in terms of reversibility.[] Other studies have indicated that the synthesis of MgTFSI2/MgCl2/DME electrolyte has led to the development of the first rechargeable Mg/S batteries with exceptional cycling stability, achieved by mitigating polysulfide dissolution. The battery is reported to primarily operate through S0/MgSx redox processes. [] It has been reported that the significance of Magnesium chloride, in the formulation of a concentrated Mg(HMDS)2/MgCl2 solution in THF electrolyte lies in its pivotal role in enabling a reverse Schlenk equilibrium. This unique preparation method facilitates the reversible deposition and dissolution of magnesium, broadening the electrochemical range and achieving an impressive coulombic efficiency of 99%. Moreover, the exceptional solubility of MgCl2 in THF, bolstered by the presence of Mg(HMDS)2, contributes to the electrolyte′s outstanding performance in terms of high reversible capacities and robust rate capabilities. This underscores the vital importance of MgCl2 in offering a novel approach for the advancement of magnesium electrolytes. []Furthermore,Magnesium chloride, is not only essential for batteries but also serves as a catalyst in olefin polymerization. It plays a critical role as a fundamental component in Ziegler-Natta catalysts employed for olefin polymerization. The presence of magnesium chloride is instrumental in facilitating the polymerization process, thereby enabling the production of diverse olefin-based polymers.[]

Our Magnesium Chloride hydrate, with a purity of ≥99.99%, is an excellent choice as a source for Magnesium electrolytes for batteries. Its properties and high purity make it highly suitable for Solar Energy Storage in Phase Change Materials for next-generation concentrating solar power (CSP) systems.[]
