Glasses and glass-ceramics for Li-ion-batteries

Porous organic polymer membranes reinforced with ceramic particles are applied in Lithium ion batteries as separators between anodes and cathodes. The mechanical stability of these separators, which are filled with a Li-ion conducting electrolyte, determine the maximum operating temperatures of the batteries and improve their resistance against short circuits or hot spots. The IKTS develops Li ion conducting filler materials based on glass ceramics. Beside the mechanical stabilizing effect these types of inorganic fillers can contribute to the overall conductivity of the separator-electrolyte arrangement.
