Lithium (Li) metal anodes have attracted considerable interest due to their ultrahigh theoretical gravimetric capacity and very low redox potential. However, the issues of nonuniform lithium deposits (dendritic Li) during cycling are hindering the practical applications of Li metal batteries. Herein, we propose a concept of ion redistributors to eliminate dendrites by redistributing Li ions

Grain boundary dominated ion migration in polycrystalline Hysteretic Ion Migration and Remanent Field in Metal Halide Perovskites. The gap in understanding how underlying chemical dynamics impact the functionality of metal halide perovskites (MHPs) leads to the controversy about the origin of many phenomena associated with ion migration in MHPs.
Hysteresis in Perovskite Solar Cellsthe key role on the hysteretic behavior in perovskite solar cells. Hence, we will summarize the recent results on ion migration, such as the role of grain boundaries (GB) on ion migration, activation energies measurements, capacitive characterization and internal electrical field modulation, etc. In
Despite the recent astronomical success of organicinorganic perovskite solar cells (PSCs), the impact of microscale film inhomogeneities on device performance remains poorly understood. In this work, we study CH3NH3PbI3 perovskite films using cathodoluminescence in scanning transmission electron microscopy and show that localized regions with increased cathodoluminescence intensity

Metal Halide Perovskites:Synthesis, Ion Migration, and Jul 26, 2018 · In comparison, in spite of the large intrinsic charge carrier mobility of MHPs, the development of MHPbased fieldeffect transistors (MHPFETs) is relatively slow, which is essentially due to the gatefield screening effect induced by the ion migration and accumulation in MHPFETs.
Origins and mechanisms of hysteresis in organometal role for the hysteretic behavior in perovskite solar cells (PSCs). Hence, this Review will summarize the recent results on ion migration such as the migrating ion species, activation energy measurement, capacitive characterization, and internal electrical field modulation, etc.
Metal halide perovskites (MHPs) have attracted broad research interest due to their outstanding optoelectronic performance. This performance has been attributed in part to the presence of polarization in these materials.
