| description | The present disclosure relates to an electrochemical cell having an elastic binding polymer that improves long-term performance of the electrochemical cell, particularly when the electrochemical cell includes an electroactive material that undergoes volumetric expansion and contraction during cycling of the electrochemical cell (such as, silicon-containing electroactive materials). The electrochemical cell can include the elastic binding polymer as an electrode additive and/or a coating layer disposed adjacent to an exposed surface of an electrode that includes an electroactive material that undergoes volumetric expansion and contraction and/or a gel layer disposed adjacent to an electrode that includes an electroactive material that undergoes volumetric expansion and contraction. The elastic binding polymer may include one or more alginates or alginate derivatives and at least one crosslinker. |
