However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
What are phase change materials?
Phase change materials are substances that are able to absorb and store large amounts of thermal energy. The mechanism of PCMs for energy storage relies on the increased energy need of some materials to undergo phase transition.
What are phase change materials (PCMs)?
Phase change materials (PCMs) used for the storage of thermal energy as sensible and latent heat are an important class of modern materials which substantially contribute to the efficient use and conservation of waste heat and solar energy.
What is phase change energy storage?
The phase change material must retain its properties over many cycles, without chemicals falling out of solution or corrosion harming the material or its enclosure over time. Much research into phase change energy storage is centered around refining solutions and using additives and other techniques to engineer around these basic challenges.
How do phase change materials store energy?
Unlike batteries or capacitors, phase change materials don’t store energy as electricity, but heat. This is done by using the unique physical properties of phase changes – in the case of a material transitioning between solid and liquid phases, or liquid and gas. When heat energy is applied to a material, such as water, the temperature increases.
How does phase change affect heat storage?
A wide variety of materials have been studied for heat storage through the phase change effect. Paraffin wax is perhaps one of the most commonly studied, thanks to its phase change occuring in a useful temperature range.
