General description

Sodium Acetate trihydrate is a hydrated sodium salt of acetic acid. It is an excellent inorganic phase change material (PCM) due to its high energy storage density and thermal conductivity, widely used in the sector of dyeing, printing, pharmacy and buffering agent.It is soluble in alcohol.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product has been enhanced for energy efficency. Click here for more information.

Application

Sodium acetate trihydrate can be used:

  • The composite of Sodium acerate trihydrate with Graphite is used as a promising materials for storage of solar thermal energy.
  • It is also used as a phase change materials in energy storage due to its high energy storage capacity.
  • Sodium acetate trihydrate has been studied to synthesis Na2FeSiO4 as novel Cathode Material for Sodium-Ion Batteries by using sol-gel method.
  • In addition, carbon coated Na3V2(PO4)3 cathode material is synthesised by using Sodium acetate trihydrate as a precursor for sodium-ion batteries to increase the cycling stability and rate capability.
  • Furthermore, sodium iron silicate was synthesized using solvothermal synthesis and tested as a cathode material for Na-ion batteries for the first time using sodium acetate trihydrate.
  • Interstingly, Sodium acetate trihydrate is also used to synthesis a anode materials of ZnFe2O4@C/G nanocomposite for Lithium-ion batteries.[6]
