  • Sulfide solid electrolyte for solid-state batteries and method for production
    Patent number: 12407016
    Abstract: A solid electrolyte for solid-state batteries comprises a phosphorous-free solid electrolyte having a cubic argyrodite structure. The solid electrolyte has a composition according to the molecular formula: Li6+xMxSb1?yS5?zR, where x=0 to 0.7; y=0 to 0.7 and z=0 to 0.7, wherein the (semi-) metal comprises M=Si, Sn, W and the halogen comprises R=I1, Cl1, Brz, Br1 and further wherein, in a case where R=I1, M=W and x>0. Furthermore, a production method is described.

  • METHOD FOR HEATING A BATTERY, AND A BATTERY
    Publication number: 20240380018
    Abstract: A method for heating a battery having individual battery cells employs semiconductor switching elements arranged between the poles of the individual battery cells. The individual battery cells are short-circuited to be heated via the semiconductor switching elements. A time phase with short-circuited individual battery cells and a time phase with individual battery cells that are not short-circuited alternate.
