摘要：
This study proposes and develops a novel ionic concentration gradient electric generator (i‐CGEG) based on the evaporation rate difference of electrolytes. The i‐CGEG with PVA–Na electrolyte achieves a thermovoltage greater than 200 mV and an energy density of 77.94 J m−2 at a temperature of 323 K. Wearable devices and their corresponding cell modules are also developed to recycle body heat. Abstract Constructing concentration differences between anions and cations at the ends of an ionic conductor is an effective strategy in electricity ge...
