Novel ceramic material uses lattice disorder to enhance electrocaloric cooling
Electrocaloric (EC) cooling works by using electricity to generate a cooling effect, which is more efficient, cost-effective, and environmentally friendly compared to traditional vapor-compression-based cooling methods. A research team led by associate Prof. Yin Lihua from Hefei Institutes of Physical Science of the Chinese Academy of Sciences developed a new route based on lattice disorder effect to improve the electrocaloric effect in BaTiO3-based systems. Their research is published in Applied Physics Letters. In their new study, Yin and his team focused on improving the EC effect in BaTiO3 (barium titanate), which is commonly used in EC cooling systems. They designed materials with a special kind of disorder in their structure, which helps enhance the cooling effect.
