Devices for electrical energy storage need to provide high energy yields as well as output power while at the same time guaranteeing safety, low costs and long operation times. The porphyrin CuDEPP [5,15‐bis(ethynyl)‐10,20‐diphenylporphinato] copper(II) is a promising electrode material for various battery systems both as anode or cathode. While it...
The Cover Feature shows a battery anode together with needle‐like dendrites under strain. Using density functional theory calculations, the influence of strain on the self‐diffusion and other properties of metal anodes is studied. Thus, the question is addressed whether strain can modify the harmful and hazardous growth of dendrites in batteries. M...
Dendrite growth poses a significant problem in the design of modern batteries, as it can lead to capacity loss and short‐circuiting. Recently it has been proposed that self‐diffusion barriers might be used as a descriptor for the occurrence of dendrite growth in batteries. As surface strain effects can modify dendritic growth, we present first‐prin...
Dendrite formation is one of the most pressing issues in nowadays battery research. Lithium based batteries are prone to forming short-circuit causing dendrites, while magnesium based batteries are not. Recently it was proposed that the tendency towards dendrite growth is related to the height of the self-diffusion barrier with high barriers leadin...
