Abstract
Official abstract text for this publication.
An electrochemical energy storage system includes two electrodes and a separator disposed between the two electrodes. The separator is mechanically flexible such that a position of the separator between the two electrodes is alternatively shiftable in respective directions towards the two electrodes depending on an electrochemical process taking place between the two electrodes and the separator has elasticity such that a shape and/or a volume of the separator is changeable depending on the electrochemical process taking place between the two electrodes.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrochemical energy storage system, comprising: two electrodes; and a separator disposed between the two electrodes, wherein the separator is mechanically flexible such that a position of the separator between the two electrodes is alternatively shiftable in respective directions towards the two electrodes depending on an electrochemical process taking place between the two electrodes such that a size of a cathode space is different from a size of an anode space as a result of alternatively shifting the position of the separator and wherein the separator has elasticity such that a volume of the separator is compressed as a result of an expansion of respective active materials of the two electrodes. 2. The electrochemical energy storage system according to claim 1 , wherein the separator is formed from a glass fiber membrane. 3. The electrochemical energy storage system according to claim 1 , wherein an electrolyte is disposed in the separator. 4. The electrochemical energy storage system according to claim 1 , wherein the two electrodes each include a coating made from a composite material, wherein the composite material comprises an electrically conductive matrix and an active material. 5. The electrochemical energy storage system according to claim 4 , wherein the electrically conductive matrix comprises a porous and mechanically flexible carbon structure. 6. The electrochemical energy storage system according to claim 4 , wherein the electrically conductive matrix of at least one of the two electrodes comprises a silicon structure. 7. The electrochemical energy storage system according to claim 6 , wherein the silicon structure comprises nanoscale, tubular structures made from silicon. 8. A battery, comprising: at least one electrochemical energy storage system according to claim 1 .
