The ionic diode structure has become one of the attractive structures in the field of moisture-based power generation. However, existing devices still suffer from poor moisture trapping, low surface charge, and inefficient ion separation, resulting in low output power. Moreover, water freezes at low temperatures (−2, with an on-load output power of up to 71.35 μW cm−2. Under medium humidity (50% RH) at low temperature (−20 °C), it provides an open-circuit voltage of 1.11 V and a short-circuit current of 15 μA cm−2.

结合离子二极管和离子水凝胶的高效耐寒湿气发电机

离子二极管结构已成为湿气发电领域颇具吸引力的结构之一。然而，现有设备仍然存在水分捕获能力差、表面电荷低和离子分离效率低的问题，导致输出功率低。此外，水在低温下会结冰（ -2 ，带载输出功率高达71.35 μW cm -2 。在中等湿度（50% RH）和低温（-20 °C）下，它提供1.11 V的开路电压和15 μA cm -2的短路电流。
