Manufacturing Methods and Technology for Hermetically Sealed Lithium SO2 Cell Batteries.

Effort is continuing on the MM and T program to establish the fabrication techniques and requirements necessary to meet hardware production levels as specified in the subject contract. The PERTTIME Network has been revised and expanded to define specific problem areas and establish a corrective action plan to meet the overall program objectives within the scheduled time frame. Hermetic cell and battery components design has been revised in an effort to meet andor exceed all performance specifications at minimum current density levels. Non-hermetic cell samples are presently being fabricated and tested under various thermal discharge profiles to simulate the proposed hermetic designs. Such results will aid in the final selection of the optimal design configuration for the hermetic prototypes. Initial equipment design and fabrication of core winding, cathodeanode manufacture, hermetic closure and electrolyte preparation and dispensing is presently underway to permit subsequent integration within an operational production line. Interface with automated equipment manufacturers continue in order to fabricate specific machine elements and procure necessary hardware within the time frame of the PERTTIME Network. Author
