Abstract: High energy density and long cycle life all solid-state electrolyte lithium-ion batteries use ceramic-polymer composite anodes which include a polymer matrix with ceramic nanoparticles, silicon-based anode active materials, conducting agents, lithium salts and plasticizer distributed in the matrix. The silicon-based anode active material are anode active particles formed by high energy milling a mixture of silicon, graphite, and metallic and/or non-metallic oxides. A polymer coating is applied to the particles. The networking structure of the electrolyte establishes an effective lithium-ion transport pathway in the electrode and strengthens the contact between the electrode layer and solid-state electrolyte resulting in higher lithium-ion battery cell cycling stability and long battery life.

Abstract: In solid-state lithium-ion battery cells, electrolyte-infiltrated composite electrode includes an electrolyte component consisting of polymer matrix with ceramic nanoparticles embedded in the matrix to form networking structure of electrolyte. The networking structure establishes effective lithium-ion transport pathway in the electrode. Electrolyte-infiltrated composite electrode sheets and solid electrolyte membranes can be used in all solid-state lithium electrochemical pouch and coin cells. Solid-state lithium-ion battery is fabricated by: (a) providing an anode layer; (b) providing a cathode layer; (c) positioning a ceramic-polymer composite electrolyte membrane between the anode layer and the cathode layer to form a laminar battery assembly; (d) applying pressure to the laminar battery assembly; and (e) heating the laminar battery assembly.
