Abstract
Official abstract text for this publication.
The use of fibril materials, such as fibril cellulose materials and other similar materials, in electrochemical cells and components thereof is generally described.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrochemical cell, comprising: a negative electrode; a positive electrode; and an electrolyte in electrochemical communication with the negative electrode and the positive electrode, wherein the electrolyte comprises a plurality of fibrils comprising cellulose or a cellulose derivative having maximum cross-sectional diameters of less than about 100 nanometers and aspect ratios of at least about 10:1. 2. The electrochemical cell of claim 1 , wherein the electrolyte comprises a solid material, and the fibrils are at least partially surrounded by the solid material. 3. The electrochemical cell of claim 1 , wherein the electrolyte is a gel electrolyte. 4. The electrochemical cell of claim 1 , wherein the electrolyte is a solid polymer electrolyte. 5. The electrochemical cell of claim 1 , wherein the negative electrode comprises electrochemically active material comprising lithium. 6. The electrochemical cell of claim 1 , wherein the negative electrode comprises lithium metal and/or a lithium metal alloy as an electrochemically active material. 7. The electrochemical cell of claim 1 , wherein the fibrils have maximum cross-sectional diameters of less than about 10 nanometers.
