Application

Calcium sulfate can be used:   
  • In the formulation of electrolytes for calcium-ion batteries. The presence of calcium sulfate helps in improving the solubility of calcium salts in the electrolyte.      
  • As a surface modifier to enhance the performance of Ni-rich lithium nickel-cobalt-manganese oxide (NCM) cathode materials in lithium-ion batteries.

General description

Calcium sulfate (CaSO4) is an inorganic compound with significant applications in material science, particularly due to its various hydrated forms, such as gypsum and plaster of Paris. It can be used in the production of solar thermal energy systems, where it serves as a heat transfer medium or in the construction of solar panels. Additionally, calcium sulfate can also be utilized in the formulation of electrolytes for calcium-ion batteries.

This study investigated the applicability of synthesized calcium peroxide (CaO2) nanoparticles for naphthalene bioremediation by permeable reactive barrier (PRB) from groundwater. According to the batch experiments the application of 400 mg/L of CaO2 nanoparticles was the optimum concentration for naphthalene (20 mg/L)
