One-sided rolling insertion of thick lithium into a 3d current collector

Abstract

A method for manufacturing an electrode for a battery cells includes supplying an active material layer, a current collector, and a dummy current collector between a first roller and a second roller; using one of the first roller and the second roller, biasing the current collector into the active material layer below an outer surface of the active material layer using the dummy current collector; and removing the dummy current collector from the active material layer.
