Hypothesis
Doping calcium-based sorbents with alkali metal chloride salts enhances thermochemical energy storage performance.
Conclusion
Doping with NaCl and KCl significantly increases the reaction rate and cycle stability of calcium-based materials for energy storage.
Supporting Evidence
- Doping with NaCl and KCl improved the effective conversion rates of calcium-based materials.
- The KCl-CaO composites showed the best performance in energy storage.
- NaCl and KCl doping increased the surface area and delayed sintering of the materials.
Takeaway
Adding salt to calcium materials helps them store energy better and work longer without breaking down.
Methodology
The study used experiments and DFT calculations to analyze the effects of NaCl and KCl on calcium-based materials.
