In this paper we demonstrate an all-solid-state Li-ion battery with a specific energy of 225 mWh g(-1) based upon the Combined mass of both the composite anode and cathode. To realize this full Cell, we pair an iron sulfide and sulfur composite cathode with a Si-based anode. The anode active material is a Si-Ti-Ni alloy with good ionic and electronic conductivity that attains a stable specific capacity of 400 mAh g-1 based upon the total mass of the composite anode. To our knowledge, this is the highest stable Si-based all-solid-state anode specific capacity reported to date. To utilize both a lithium free anode and cathode, we adopt a pre-lithiation technique involving stabilized lithium metal powder. This is the first time that this technique has been demonstrated in an all-solid-state battery.
