Nickel Zinc Battery Improvement

The overall technical objective for this proposed effort is to develop 1,000 amp-hour, minimum Ni-Zn battery concept that will achieve 75% of capacity, or better, through 200+ Navy Equivalent Charge/Discharge cycles. This will include a detailed three-dimensional design model of the cell that includes key components and design parameters critical to the performance. Examples of these components and parameters include electrode dimensions and separator design. The design package will also include projected capacity, power, and cycle life performance. This will be supported by test data generated by a series of 140 Ah cell evaluations specifically designed to include features considered for use in this large format concept. In addition, the design package will include a detailed discussion on the manufacturability of the proposed cell concept. This will involve an evaluation of the various manufacturing process steps and how they will need to change in order to accommodate the manufacturing of a large format cell as compared to the current G31 format. Æsir is proposing to exercise the Phase I Option and will develop detailed design specifications for the proposed cell concept. This will include a detailed drawing package of the cell design, including key components and manufacturing parameters. In addition, a manufacturing flow process plan for the cell concept will be developed and finalized so to be readily implemented in a subsequent Phase II. This will include documentation of processes, tooling, and fixtures on the assembly line.
