| Outline of Final Research Achievements |
Lithium hydroxide (LiOH)/lithium hydroxide monohydrate (LiOH·H2O) reaction is a promising one for low-temperature thermal energy below 100 degrees Celsius, because LiOH·H2O can store thermal energy around 70 degrees Celsius with density of 1,440 kJ/kg. Towards practical use, hydration rate of LiOH is required to be greatly promoted. To achieve this objective, in this study, a hybrid material of LiOH and mesoporous silica (MPS) was tried to prepare for supporting LiOH particle inside pore of MPS by impregnating method with MPS and LiOH or LiNO3 aqueous solution.
The material was prepared at various LiOH or LiNO3 solution concentrations, impregnation times, and number of impregnations. As a result, it was demonstrated that initial hydration rate for 10 min. and endothermic heat of prepared material were improved compared to pure lithium hydroxide and pure mesoporous silica.
