APPLICATIONS OF TECHNOLOGY:
- Rechargeable batteries (lithium-ion, lithium-sulfur batteries) for electric vehicles
- High ionic conductivity
- High transference number (0.99)
- Excellent mechanical and adhesive properties
- Wide electrochemical stability window
Berkeley Lab researchers have developed single-ion-conducting hybrid solid electrolytes for use in all-solid-state rechargeable lithium batteries – an invention of interest in the quickly expanding electric car market. This hybrid is the first to achieve and possess the benefits of both inorganic and organic single-ion-conducting electrolytes without shortcomings such as polarization effects, inability to adhere to moving boundaries of active particles in the electrode during charge / discharge, low conductivity, and inability to achieve solid state at room temperature.
The Berkeley Lab electrolytes are composed of inorganic sulfide glass and non-flammable organic electrolytes. Using mechanochemical approaches for synthesis, this Berkeley Lab group produced solid electrolytes with good ionic conductivity, optimal shear modulus, high transference number, large electrochemical stability window, and good adhesive properties necessary for functioning batteries.
