Definitions

  • the aluminum layer 31 is in contact with the solid electrolyte layer 40.
  • lithium in the lithium layer 32 moves to the solid electrolyte layer 40 side, but lithium is alloyed with aluminum in the aluminum layer 31 before reaching the solid electrolyte layer 40. To do. For this reason, it is difficult for lithium to flow out from the solid electrolyte layer 40 side by discharge.
  • the thickness of the negative electrode layer 30 is not particularly limited, but in the present embodiment, it is 10 to 400 ⁇ m, preferably 20 to 200 ⁇ m.
  • the film thickness of the aluminum layer is, for example, 5 to 200 ⁇ m, preferably 10 to 100 ⁇ m.
  • the thickness of the lithium layer is, for example, 5 to 200 ⁇ m, preferably 10 to 100 ⁇ m.
  • the manufacturing method of Example 7 enables the interface bonding between the solid electrolyte and the negative electrode active material even with a relatively low battery restraint pressure, and has a low resistance and high durability. We were able to provide a battery.
