Embodiment Construction

[0022] One or more specific embodiments are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be understood that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints , which may vary from implementation to implementation. Furthermore, it should be understood that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, production, and fabrication for those of ordinary skill having the benefit of this disclosure.

[0023] As noted above, during the production of certain cells, such as lithium-ion cells, such cells may experience an increase in stress. Methods of degassing cells have ...
