Abstract

A battery structure is disclosed. The battery structure includes a first current collector layer, a first active material layer, a spacer layer, a first plastic frame, a second active material layer and a second current collector layer. The first active material layer is disposed on the first current collector layer. The spacer layer is disposed on the first active material and completely covers the top surface of the first active material layer. The first plastic frame is disposed on the side wall of the spacer layer and the top of the first plastic frame has a protruding part which extends to the top surface of the spacer. The second active material layer is disposed on the spacer layer and the protruding part. The second active material is isolated from the first active material via the space layer and the protruding part. The second current collector layer is disposed on the second active material layer.

Dependent claims

A battery structure, comprising:

a first current collector layer;
a first active material layer, disposed on the first current collector layer;
a ceramic spacer layer, disposed on the first active material layer, the spacer layer completely covering a top surface of the first active material layer;
a first plastic frame, disposed on a side wall of the spacer layer, the first plastic frame having a protruding part, the protruding part extending inwardly over a top surface of the spacer layer and directly contacting the top surface of the spacer layer;
a second active material layer, disposed on the spacer layer and the protruding part and directly contacting the spacer layer and the protruding part, isolated from the first active material layer via the spacer layer and the protruding part, wherein the protruding part extends partly over the top surface of the spacer layer between the top surface of the spacer layer and a bottom surface of the second active material layer and beyond a peripheral surface of the spacer layer and a peripheral surface of the second active material layer;
and
a second current collector layer, disposed on the second active material layer.
