氯化锂改性氢氧化镁是一种热化学储能的候选材料。研究了氯化锂混合比、水化温度和水蒸气压对材料水化行为的影响。评估了所有实验条件下的热输出密度。当氯化锂与氢氧化镁的摩尔混合比为0.10 mol氯化锂时，水化温度为110℃，水蒸气压力为57.8 kPa，单位重量氯化锂改性氢氧化镁的热输出密度为1.40 × 10(3) kJ kg（-1）。该值高于正品氢氧化镁的热输出密度。
Lithium chloride-modified magnesium hydroxide is a candidate material for thermochemical energy storage. In this work, the effects of lithium chloride mixing ratio, hydration temperature, and water vapor pressure on the hydration behavior of the material are investigated. Heat output densities for all experimental conditions are evaluated. The heat output density per unit weight of lithium chloride-modified magnesium hydroxide, at a molar mixing ratio of 0.10 mol of lithium chloride per mol of magnesium hydroxide, is 1.40 x 10(3) kJ kg(-1) at a hydration temperature of 110 degrees C and a water vapor pressure of 57.8 kPa. This value is higher than the heat output density of authentic magnesium hydroxide.
