1.Power: Nanophosphate products can pulse at high discharge rates to deliver unmatched power by weight or volume.

Figure 1 shows the cell voltage remains relatively flat during and the delivered Ah capacity does not change significantly , no matter what the rate of discharge.

Cells resistance changes with cell temperature. The warmer the cell, the lower it’s resistance becomes.

Figure 2 shows how temperature affects the cell’s terminal voltage during a one hour discharge.

2.Life: Nanophosphate technology delivers calendar and cycle life. A123 cells can deliver thousands of 100% depth-of-discharge(DoD) cycles, a feat unmatched by other commercial lithium ion cells.

Figure 3 shows how the capacity of cell decreases with respect to the number full depth of discharge(DoD) cycles that it delivers. For example, at 25℃, the cell can deliver over 5000 full DoD cycles before it’s capacity decreases to 80% of it’s beginning of life(BoL) capacity.

Figure 4 shows how the cells lose capacity over time, sitting at 100% SOC in various temperatures. Within three months, the cell lose 3% of their initial capacity, but the aging slows, and over the next one year they only lose another 1% at 25℃. Temperature is a significant factor in calendar aging. For example i n two years, the capacity loss 6% at 25℃, 11% at 25℃ and 22% at 45℃.
