Figure 3 shows the voltage at the end of discharge. As seen in this graph, with the exception of the initial 25 cycles where the cell equilibrated, the end-point voltage is uniform and stable throughout the entire testing period. Discharge Profile Figure 3. End of Discharge Voltage vs. Number of Recharge Cycles Peak Power. The power and energy densities of the PolyPlus solid-state lithium battery is one of the highest known for advanced battery systems.
High power is crucial for vehicle, utility, and telecommunications applications.
A high specific energy density is critical for those applications where battery weight is important, such as vehicles, satellites, portable laptop computers, and camcorders. Furthermore, the low toxicity and low cost of materials used in the PolyPlus solid-state cell makes it an exceptionally competitive system overall. PolyPlus Technical Papers.
