Abstract

Electrochemical cells and methods of making electrochemical cells are described herein. In some embodiments, an apparatus includes a multi-layer sheet for encasing an electrode material for an electrochemical cell. The multi-layer sheet including an outer layer, an intermediate layer that includes a conductive substrate, and an inner layer disposed on a portion of the conductive substrate. The intermediate layer is disposed between the outer layer and the inner layer. The inner layer defines an opening through which a conductive region of the intermediate layer is exposed such that the electrode material can be electrically connected to the conductive region. Thus, the intermediate layer can serve as a current collector for the electrochemical cell.

First claim

The invention claimed is:

1. An apparatus, comprising:
a multi-layer sheet for encasing an electrode material of an electrochemical cell, the multi-layer sheet including
an outer layer;
an intermediate layer including a conductive substrate; and
an inner layer formed with a material configured to be thermally bondable to itself, and disposed on a portion of the conductive substrate, the intermediate layer being disposed between the outer layer and the inner layer,
the inner…
