Nickel Zinc Main Storage Battery

The Technical Objective for this Phase II effort is to develop, build, and deliver a large format Ni-Zn cell intended to be used in a submarine main storage battery. As laid out in the conclusions and recommendation of the Phase I Final Report, this cell will have a nameplate capacity of about 1,000 Ah with an aspect ratio (height to width ratio) of about 1.2.Ā ĀFollowing the Phase I recommendations, the cell electrodes will have tabs extending the entire length of the cathodes and thisĀwill improve current density distribution and enhance energy and power efficiency. Some of the key parameters for the deliverable cell is: Capacity: 1,000 Ah Nominal Voltage: 1.65 V Aspect Ratio: 1.2 Weight: ~55 lbs. Height: 16.55 in. Top footprint: 14.34 in. X 3.52 in. Base footprint: 13.78 in. X 2.95 in. During the 12-month, Base period, Ųsir intends to build 16 ~1,000Ahr prototype cells and deliver 12 of these to the Navy for testing and evaluation. In the Option 1 phase, Ųsir would order additional parts for up to 12 cells and produce those deliverables within 6 months from the end of the Base period. These 12 units would be delivered to NSWC ¢ Crane for additional testing and evaluation. In the Option II Phase, Ųsir willĀprovide engineering technical development and performance improvement support services for all Ųsir Technologies, Inc. (Ųsir) produced Nickel-Zinc (NiZn) cells that are currently being produced, designed, and tested for use on US Navy submarines, as well as all future Ųsir manufactured US Navy NiZn cells upon request by the Government during the Period of Performance (POP)Āof this contract.
