Abstract
An electrode heat treatment device and associated method for fabricating an electrode are described, and include forming a workpiece, including coating a current collector with a slurry. The workpiece is placed on a first spool, and the first spool including the workpiece is placed in a sealable chamber, wherein the sealable chamber includes the first spool, a heat exchange work space, and a second spool. An inert environment is created in the sealable chamber. The workpiece is subjected to a multi-step continuous heat treatment operation in the inert environment, wherein the multi-step continuous heat treatment operation includes continuously transferring the workpiece through the heat exchange work space between the first spool and the second spool and controlling the heat exchange work space to an elevated temperature.
