1. A solid-state lithium-ion battery cell comprising:
a solid electrolyte layer member comprising a predetermined amount of solid electrolyte particles, the solid electrolyte layer member having a first side for placement in lithium ion-transport contact with a layer of anode active material and an opposing side for placement in lithium ion-transport contact with a layer of cathode active material, both of the first and opposing sides of the solid electrolyte layer member having a surface characterized by a lopolgical surface pattern of projections and adjacent recesses between the projections extending into the solid electrolyte layer, the pattern of recesses increasing the area of the shaped surface and shortening the ion transport distance as compared with a flat surface, the thickness of the solid electrolyte layer member being 5 micrometers to about 1000 micrometers;
an anode layer member having opposing sides and a uniform thickness of 5 micrometers to 500 micrometers, the anode layer member comprising a bonded mixture of particles of anode active material and solid electrolyte particles, the respective particles having maximum dimensions in the nanometer and micrometer range of 2 nanometers to 500micrometers, the anode layer member having a side facing toward, and coextensive with, an opposing side of the solid electrolyte layer member and shaped for lithium ion-transport contact with the facing side of the solid-electrolyte layer member; and
a cathode layer member having opposing sides and a uniform thickness of 5 micrometers to 500 micrometers, the cathode layer comprising a bonded mixture of particles of cathode active material and solid electrolyte particles, the respective particles having maximum dimensions in the nanometer and micrometer range of 2 nanometers to 500 micrometers, the cathode layer member having a side facing toward, and coextensive with, an opposing side of the solid electrolyte layer member and shaped for lithium ion-transport contact with the facing side of the solid electrolyte layer member.
