Printed Honeycomb-Structured Reduced Graphene Oxide Film for Efficient and Continuous Evaporation-Driven Electricity Generation from Salt Solution

Water-evaporation-induced electricity generation provides an ideal strategy to solve growing energy demand and supply power for self-powered systems because of its advantages of a highly spontaneous process, continuous power generation, and low cost. However, the reported evaporation-induced generators are limited to working only in deionized (DI) water, leading to a low output power. Herein, we utilize a modified multiple ion mode to...
