Sorption thermal batteries are systems that can store heat for a long period without heat loss through the reaction of the gas and adsorbent. However, a sorption thermal battery driven by a heat source of less than 100 ℃ is required because solar and waste heat are low-temperature heat sources. Given that the sorption process in solid sorbents typically requires high charging temperatures, this study investigates the loading of water into the sorbent in combination with ammonia to lower the charging temperature. Zeolite 13X, HZSM-5 and HKUST-1 are evaluated as the potential sorbents based on their material properties, water loading capacity, and ammonia sorption performance. Among them, zeolite 13X loaded with water is selected as the working pair and applied to a laboratory-scale sorption thermal battery to evaluate its energy storage performance. When the charging pressure of ammonia was 5 bar under normal coolant conditions, the energy storage density was 204.2 kWh m⁻³ and the coefficient of performance was 0.53. It can be operated with a low-temperature heat source of 80 ℃; therefore, renewable heat sources such as solar energy or industrial waste heat, can be used. Then the coefficient of performance increases 6.2 times from 0.53 to 3.31 (with the coolant). The ammonia- sorption thermal battery based on zeolite 13X loaded with water is expected to play an important role in thermal energy storage to solve the imbalance problem between demand and supply of renewable energy.

吸附热电池是可以长期储存热量而不通过气体和吸附剂的反应损失热量的系统。然而，由于太阳能和废热都是低温热源，因此需要小于100℃的热源驱动的吸附热电池。鉴于固体吸附剂中的吸附过程通常需要高装料温度，本研究研究了将水与氨结合加载到吸附剂中以降低装料温度。根据材料特性、水负载能力和氨吸附性能，将沸石 13X、HZSM-5 和 HKUST-1 评估为潜在的吸附剂。其中，选择负载水的13X沸石作为工作对，并将其应用于实验室规模的吸附热电池，以评估其储能性能。^-3，性能系数为0.53。可在80℃低温热源下运行；因此，可以使用可再生热源，例如太阳能或工业废热。那么性能系数从 0.53 增加到 3.31（使用冷却液）6.2 倍。基于载水13X沸石的氨吸附热电池有望在热能储存方面发挥重要作用，解决可再生能源供需失衡问题。
