With the rapid increase in population and the improvement of living standards, problems such as imbalance in energy supply and demand and environmental pollution are becoming increasingly prominent. People are focusing on renewable energy, and the energy form has shifted from single fossil fuels to diversified and clean energy. At present, renewable energy is generally intermittent and unstable, and heat storage technology must be used for utilization. Heat storage technology includes three categories: sensible heat storage, latent heat storage (also known as phase change storage) and chemical reaction heat storage. Among them, phase change heat storage technology is the storage and release of thermal energy through the solid-liquid (solid) phase change process of phase change materials. It has the advantages of high heat storage density, stable phase change temperature and easy process control. Heat storage technology is an important technology for improving energy utilization efficiency and protecting the environment. It can be used to solve the contradiction between the mismatch between heat supply and demand. It has broad application prospects in the fields of solar energy utilization, electricity "peak shifting and valley filling", waste heat and waste heat recovery, and energy saving in industrial and civil buildings and air conditioning.
