Abstract: A composition-of-matter is described herein, comprising a first layer and third layer separated by a second layer. The first and third layers each comprise a thermoplastic polymer and a substance capable of reversibly releasing lithium or a delithiated form of the substance. The second layer comprises a thermoplastic polymer and is capable of conducting lithium ions. Further described herein is an electrochemical system comprising the composition-of-matter, wherein the first and third layers are each a lithium-based electrode, and batteries and supercapacitors comprising such an electrochemical system, as well as methods for preparing the composition-of-matter or the electrochemical system.

Abstract: A method of manufacturing an electrochemical system comprising an electrode is described herein, comprising dispensing, in a configured pattern corresponding to the shape of the electrode, a model composition which comprises a substance capable of reversibly releasing an electrochemically-active agent (such as lithium) or depleted form of same, wherein dispensing comprises heating a filament comprising the model composition and dispensing a heated composition. Further described is an electrochemical system comprising an electrode which comprises a composite material, as well as batteries and supercapacitors comprising such a system. The composite material comprises a thermoplastic polymer and substance capable of reversibly releasing an electrochemically-active agent (such as lithium) or depleted form of same, wherein at least 20 weight percents of the composite material is thermoplastic polymer.
