Definitions

  • the inventor of the present invention has made extensive studies. That is, in order to solve the above problems, the following means are provided.
  • An all-solid-state battery includes a positive electrode layer including a positive electrode active material layer and a positive electrode current collector, a negative electrode layer including a negative electrode active material layer and a negative electrode current collector, and a solid electrolyte layer. , an insulating film, and The insulating film has therein a through hole for accommodating a laminate in which the positive electrode active material layer, the solid electrolyte layer, and the negative electrode active material layer are sequentially laminated, The laminate and the insulating film are arranged between the positive electrode current collector and the negative electrode current collector, The outer shape of the insulating film is larger than the outer shape of the positive electrode current collector and the negative electrode current collector when viewed from the stacking direction of the laminate.
  • the shape of the through-hole H when viewed from the z direction is any shape that allows the insulating film 50 to accommodate the laminate 30 therein.
  • the shape of the through-hole H when viewed from above in the z-direction is, for example, similar to the laminate 30 .
  • An example in which the through hole H and the laminate 30 are circular in shape will be described below.
  • the length difference and the length ratio between the insulating film 50 and the positive electrode current collector 11A and the negative electrode current collector 13A in the x direction are the same as those of the insulating film 50 and the positive electrode current collector 11A and the negative electrode current collector in the y direction.
  • the length difference and length ratio with 13A can be similar to .
  • the insulating film 50 does not interfere with the contact between the laminate 30 and the positive electrode current collector 11A and the negative electrode current collector 13A. . Therefore, when the insulating film 50 is thinner than the laminate 30, the adhesion between the laminate 30 and the positive electrode current collector 11A as well as between the laminate 30 and the negative electrode current collector 13A is enhanced, and the shift of the laminate 30 is further suppressed. . Moreover, when the thickness of the insulating film 50 is thicker than a predetermined value, it is particularly easy to obtain the effects of suppressing short circuits and suppressing displacement of the laminate.
  • FIG. 7 and 8 are schematic cross-sectional views of all-solid-state batteries 103 and 104 according to Modification 3.
  • FIG. The arrangement of the all-solid-state batteries 103 and 104 according to Modification 3 when viewed from the stacking direction is the same as the arrangement of the all-solid-state battery 100 according to the first embodiment.
  • All-solid-state batteries 103 and 104 are examples of arrangement when electrically connected in series and in parallel, respectively.
  • FIG. 9 is a schematic top view of an all-solid-state battery 105 according to Modification 4.
  • FIG. 10 is a schematic cross-sectional view of an all-solid-state battery 105 according to Modification 4.
  • An all-solid-state battery 105 according to Modification 4 has a plurality of units.
  • the all-solid-state battery 105 multiple units are arranged, for example, in the same plane. That is, the multiple units are arranged side by side at the same position in the z direction.
  • 9 and 10 show an example having a first unit U3 and a second unit U4.
  • each of a plurality of units has a plurality of laminates 30e to 30h and through holes H, for example.
  • Other configurations are the same as those of the all-solid-state battery 100 according to the first embodiment.
  • Example 2 The AC electrical resistance was measured in the same manner as in Example 1 except that the thickness T2 of the insulating film was set to 200 ⁇ m and 100 ⁇ m.
