Abstract
In all-solid-state batteries, the electrode has been generally fabricated as a composite of active material and solid electrolyte to imitate the electrode of lithium-ion batteries employing liquid electrolytes. Therefore, an efficient protocol to spatially arrange the two components with a scalable method is critical for high-performance all-solid-state batteries. Herein, a design of the all-solid-state electrode is presented for all-solid-state batteries with higher energy density than the typical composite-type electrode. The proposed electrode, composed mostly of the active materials, has a seamless interface between the active materials, which allows interparticle lithium-ion diffusion. Thus, the solid electrolyte can be completely excluded during the electrode manufacturing process, which enables higher flexibility for fabrication protocol by relieving the concerns about (electro)chemistry related to solid electrolytes. Furthermore, it can dramatically enhance the normalized energy density by increasing the content of the active material in the electrode. This electrode concept provides a meaningful advance toward high-performance all-solid-state batteries. Copyright © 2020 American Chemical Society.
