Abstract: An electrochemical cell system includes a housing defining an internal volume, an electrochemical cell disposed within the internal volume and a medium disposed in the internal volume around the electrochemical cell. The housing is operably coupled to a pressurizing system which is configured to apply a predetermined pressure on the medium so as to cause the medium to exert a substantially uniform pressure on a surface of the electrochemical cell. The pressure may be in a range of about 0.1 MPa to about 50 MPa.

Abstract: Embodiments described herein relate to binders including one or more portions, and electrochemical cells including the same. Specifically, in some embodiments, binders may include a first portion, a second portion, and, optionally, a functional portion coupled to at least one of the first portion or the second portion. In some embodiments, the functional portion may also be coupled to first portion. In some embodiments, the second portion is coupled to the first portion in a linear structure, or grafted as a side chain at a predetermined location along a length of the first portion. In some embodiments, the first portion has a first glass transition temperature, and the second portion has a second glass transition temperature. The second glass transition temperature may be greater than the first glass transition temperature.

Abstract: The invention provides rechargeable batteries including a solid state electrolyte (SSE) containing an alkali metal disposed between two electrodes. The batteries are volumetrically constrained imparting increased stability under voltage cycling conditions, e.g., through microstructure mechanical constriction on the solid state electrolyte and the electrolyte-electrode interface. These batteries of the invention are advantageous as they may be all-solid-state batteries, e.g., no liquid electrolytes are necessary, and can achieve higher voltages with minimal electrolyte degradation.
