摘要Oxalic acid dihydrate (OAD), which is inexpensive and has a high initial phase transition enthalpy, is a very promising phase change material. However, severe material leakage can occur owing to the large amount of steam generated when OAD is heated to melt. This behavior subsequently degrades the thermophysical properties of OAD over time, thereby hindering further application of OAD. In the present study, NaCl was introduced as an additive in OAD to reduce its melting point. Results showed that a NaCl additive content of 9 wt% was the optimal amount to reduce the phase change temperature of OAD and produce sharp endothermal and exothermal peaks without reducing the phase change enthalpy significantly. Furthermore, minimal changes in the thermophysical properties of this mixture were observed after being subjected to 100 thermal cycles. The current findings are expected to broaden the application scope of OAD for thermal energy storage. (C) 2016 Elsevier Ltd. All rights reserved.
