The program has advanced to the level of full-size, prototype cell fabrication and evaluation. EPP nickel electrodes are now being prepared of up to 24 Ah/plate (at C/3 drain rate) at design thickness (2.5 mm). Iron electrodes of the composite-type are delivering 24 Ah/plate (at C/3) at target thickness (1.0 mm). Both plates are displaying good capacity stability at 130 to 175 test cycles, respectively, in some of the 3 plate cell tests. Finished cells are delivering up to 58 Wh/Kg at C/3, based on projected weight of the finished cell and in the actual designed cell volume. Reduction in cell resistance, reduction in nickel plate processing time and swelling on cycling are areas of major effort to reach the final battery objectives. Thermal nickel electrodes are showing promise in full size plate tests (up to 22 Ah in a plate of only 2.3 mm thickness) and will be evaluated in finished cells as soon as the technology shows repeatable results in full-size test plates.
