Imaging real-time amorphization of hybrid perovskite solar cells under electrical biasing
Min-cheol Kim, Namyoung Ahn, Diyi Cheng +11
Perovskite solar cells have drawn much attention in recent years, owing to its world-record setting photovoltaic performances. Despite its promising use in tandem applications and…
Pressure-tailored lithium deposition and dissolution in lithium metal batteries
Chengcheng Fang, Bingyu Lu, Gorakh Pawar +8
A porous electrode resulting from unregulated Li growth is the major cause of the low Coulombic efficiency and potential safety hazards of rechargeable Li metal batteries. Strategi…
Local structure of glassy lithium phosphorus oxynitride thin films: a combined experimental and ab initio approach
Maxwell A. T. Marple, Thomas A. Wynn, Diyi Cheng +3
Lithium phosphorus oxynitride (LiPON) is an amorphous solid-state lithium ion conductor displaying exemplary cyclability against lithium metal anodes. There is no definitive explan…
Unveiling the Stable Nature of the Solid Electrolyte Interphase between Lithium Metal and LiPON via Cryogenic Electron Microscopy
Diyi Cheng, Thomas Andrew Wynn, Xuefeng Wang +11
The solid electrolyte interphase (SEI) is regarded as the most complex but the least understood constituent in secondary batteries using liquid and solid electrolytes. The nanostru…
