Title：Multiphase-Interfacial Regulation and Enhanced Mass Transport in Micro/Nano Power Sources

Abstract:  Owing to the rapid development of information technology, the increasing portable micro-electronic devices such as micro drone, micro sensors and lab-on-a-chip have urgent demand of micro power source with superior performances, including high power density, long-period operation and low-cost.However, the unstable gas-liquid interface introduces the micro/nano power sources insufficient and unstable power generation. Recently,our group has proposed the electrode’s mass-transport network with low seepage threshold combining interfacial regulation and mass transfer enhancement. It realizes an efficient loading of catalyst and coordinated regulation of reactant and charged mass transfer. The electrode/electrolyte interface is successfully optimized according to the criterion of "minimum surface adsorption energy", realizing the bubbles’ efficient and low resistance detachment in micro-channel.
