Abstract 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… More >
