Abstract

This paper reports the electrode performance of a Si anode composed of nanoparticles prepared by spray deposition in a solid-state cell. Upon lithiation, the Si nanoparticles undergo volume expansion, structural compaction, and appreciable coalescence in the confined space between the solid electrolyte layer and current collector in the solid-state cell to form a continuous film similar to that fabricated by the evaporation process. Hence, the particulate anode exhibited excellent performance, previously observed only in thin-film systems. The anode prepared by the scalable process delivers 2655 mAh g–1 even at a high discharge current density of 5.48 mA cm–2 (24C).
