  • All-solid-state lithium battery, and production method therefor
    Patent number: 9105903
    Abstract: The invention relates to an all-solid-state lithium battery and to a method for producing such a battery. The all-solid-state lithium battery includes first and second electrodes separated by a solid electrolyte. The second electrode is formed by a composite material including an electrochemically-active material made of a lithium-ion insertion material, and an amorphous lithium-based material which is an ionic conductor for the lithium ions and which is inert relative to the electrochemically active material.
    Type: Grant
    Filed: September 1, 2011
    Date of Patent: August 11, 2015
    Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES
    Inventors: Michael Roffat, Frederic Le Cras
