英文摘要Thermochemical heat storage material inorganic hydrate LiOH is selected as a promising candidate material for storing low-temperature heat energy because of its high energy density (1440 kJ/kg) and mild reaction process. However, the low hydration rate of LiOH limits the performance of low temperature thermochemical heat storage system as well as the thermal conductivity. In this study, porous-graphene/LiOH composite thermochemical heat storage materials with strong water sorption property and higher thermal conductivity were synthesized by hydrothermal process. The experimental results show that the hydration rate of the composites was greatly improved. The heat storage density of the composite materials was increased by 47% (from 661 kJ/kg to 974 kJ/kg). By combing the porous graphene, the thermal conductivity of composites with different contents were highly increased by 21.1% to 78.7%, but the increase of heat storage density is opposite to that of thermal conductivity. The development of high-performance materials for thermochemical heat storage should consider the relationship between the heat storage density and thermal conductivity of the material, and the thermal conductivity of the supporter needs to be further improved.
