SILICON ANODE, MANUFACTURING METHOD THEREOF, AND BATTERY COMPRISING THE SAME

The present disclosure relates to a silicon anode, a method for manufacturing the same, and a battery including the same. Particularly, the silicon anode improves the interfacial contact between the silicon anode and a sulfide-based solid electrolyte layer, and thus the interfacial contact can be maintained uniformly during lithiation even under low pressure, and high delithiation capacity and coulombic efficiency can be realized.In addition, the battery allows the lithium-alloying metal layer stacked on the anode active material layer to be applied to the silicon anode, and thus the lithium-alloying metal layer stacked on the silicon anode forms alloy with lithium in real time through the conduction of lithium ions from the solid electrolyte during lithiation/delithiation, and the silicon anode becomes soft and adhesive and shows improved interfacial contact between the lithium-alloying metal layer and the solid electrolyte layer, resulting in improvement of the life characteristics and capacity retention of the battery.
