Abstract
Methods for preparing an electrode may include compressing an electrode dry mixture comprising an active material and an electrolyte material to form an electrode film. An electrolyte dry mixture or a stand-alone solid-state electrolyte film is compressed against a surface of the electrode film to form a laminate of an electrolyte layer and the electrode film. The electrolyte dry mixture may include the electrolyte material. Compressing the electrode dry mixture may include calendering the electrode dry mixture. Compressing the electrolyte dry mixture or stand-alone electrolyte film may be accomplished also by calendering. The electrolyte material may include a glass ceramic and, optionally, an air-stabilizing dopant. The glass ceramic may include LiPS. Thus, the electrodes may include a composite cathode and a solid-state electrolyte layer. The methods may be applicable for a solvent-free process to form electrodes and electrochemical cells and batteries including the electrodes.
