Lithium acetate dihydrate has various applications in industries such as pharmaceuticals, ceramics, and research laboratories. It is often utilized as a source of lithium ions in chemical reactions and as a precursor in the synthesis of other lithium compounds.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.
Application
Lithium acetate dihydrate is a significant salt with a wide range of applications. It is utilized as a component in drug formulation and therapy, as a buffer for DNA and RNA gel electrophoresis, and as an additive or catalyst in textiles and polymer production. Additionally, it serves as a ferromagnetic nanoparticle, catalyst, and precursor material for batteries
Our Lithium acetate dihydrate, with a purity of 99.9% on a trace metals basis, serves as an excellent precursor for batteries and catalysis. Its low trace metals content and anions make it particularly well-suited for these applications.

- Lithium Iron Pyrophosphate (LiFe1.5P2O7) with monoclinic structures was successfully synthesized using Lithium acetate dihydrate in combination with other metal acetates, in a ratio of Li/Fe/P = 1.05:1.5:2, through a wet-chemical method. Maintaining the appropriate lithium concentration is crucial to prevent stoichiometry loss in the final product. This material has found application as a positive electrode in Lithium-ion batteries. Remarkably, the electrode demonstrates excellent incremental capacity, indicating a stable structure during the initial cycle, with redox peaks observed at 3.33 and 3.22 V versus Li0/Li+
- LiMn2O4 films were synthesized on Au foil using the sol-gel and spin-coating techniques, employing Lithium acetate dihydrate and manganese acetate tetrahydrate in a Li/Mn ratio of 1.1/2. The particles used had an average size of approximately 300 nm. To investigate the morphological changes during over-discharging, the EC-HS-AFM technique was utilized. The images captured revealed the presence of wrinkle-like and step-like structures on the particle surface. These structures were attributed to stresses induced by structural distortion during the phase transformation from cubic (LiMn2O4) to tetragonal (Li2Mn2O4). The formation of the Li2Mn2O4 phase was confirmed through ex situ XRD analysis. Furthermore, by analyzing the EC-HS-AFM images, the particle surface area was quantitatively extracted as a function of potential, providing insights into the irreversible expansion/contraction behavior of the particles
- Cobalt-free cathodes, specifically Mg and Zr modified LiNi0.5Mn1.5O4 (LNMO), were synthesized using Lithium acetate dihydrate and other metal acetates via a citric acid sol-gel method. The modifications aimed to improve the electrochemical performance of the cathode, particularly at high temperatures, by limiting Mn dissolution and adjusting interstitial sites. This modification resulted in increased stability of the cathode, extending the cycle life to 1000 cycles at both 25 and 50 °C
