DUAL LAYER SOLID STATE BATTERIES

摘要

Methods for fabrication of electronic systems and systems therefrom are provided. An electronic system includes a first substrate (202) having a first surface (202a) and a second substrate (208) having a second surface (208a) facing the first surface. The system also includes a plurality of battery cell layers (106-112) disposed on a plurality of laterally spaced areas on the first and second surfaces (203, 209). In the system, portions of the battery cell layers on the first surface are in physical contact with portions of the battery cell layers on the second surface and the battery cell layers on the first surface and the second surface form a plurality of electrically interconnected battery cells (206, 212) on the first and the second surfaces that are laterally spaced apart and that define one or more batteries

1. An electronic system, comprising:
a first substrate having a first surface and a second substrate having a second surface opposed from said first surface; a plurality of projections disposed on each of said first surface and said second surface in laterally spaced areas along a lateral direction that is parallel to the first and second surfaces; and a plurality of battery cell layers disposed respectively on each of said plurality of projections so as to form a first plurality of laterally spaced battery cells on said first surface having a first periodic pattern that is laterally spatially offset from a second plurality of laterally spaced battery cells disposed on said second surface and having a second periodic pattern; wherein said first and second periodic patterns are selected so that, after an alignment of the first and second substrates, a portion of a cathode contact region of each of said first plurality of laterally spaced battery cells is aligned with and forms an electrical contact with an anode contact region of a respective first laterally adjacent one of said second plurality of laterally spaced battery cells, and an anode contact region of each of said first plurality of laterally spaced battery cells is aligned with and forms an electrical contact with a cathode contact region of a respective second laterally adjacent one of said second plurality of laterally spaced battery cells; and wherein each of the plurality of projections includes transverse surfaces which extend in directions which are transverse to the lateral direction, and said plurality of battery cell layers are respectively disposed on the plurality of projections on the transverse surfaces.
