Since the inception of the unprecedented rise of halide perovskites for photovoltaic research, ion migration has shadowed this material class with undesirable hysteresis and degradation effects, limiting its practical implementations. Unfor...
On the Relative Importance of Li Bulk Diffusivity and Interface Morphology in Determining the Stripped Capacity of Metallic Anodes in Solid-State Batteries [0.03%]
固态电池中金属阳极剥离容量的相对重要性——锂体相扩散和界面形态的影响
Marco Siniscalchi,Junliang Liu,Joshua S Gibson et al.
Marco Siniscalchi et al.
Lithium metal self-diffusion is too slow to sustain large current densities at the interface with a solid electrolyte, and the resulting formation of voids on stripping is a major limiting factor for the power density of solid-state cells. ...
