Abstract:
The present disclosure provides an electrochemical cell that includes a double-sided electrode. The double-sided electrode includes a first electroactive material layer, a second electroactive material layer, and a current collector disposed between the first and second electroactive material layers. Each of the first and second electroactive material layers may include a plurality of electroactive material sub-films and a plurality of buffer layers disposed between adjacent electroactive material sub-films. The electrochemical cell further includes a first single-sided electrode substantially aligned with the first electroactive material layer; a first separator physically separating the first single-sided electrode and the first electroactive material layer; a second single-sided electrode substantially aligned with the second electroactive material layer; and a second separator physically separating the second single-sided electrode and the second electroactive material layer. The current collector may include at least one surface coated with an adhesive layer.
