Title: An investigation of the resistance rise and power fade in high-power Li-ion cells.

Abstract

Two different cell chemistries, Gen 1 and Gen 2, were subjected to accelerated aging experiments. In Gen 1 calendar-life experiments, useful cell life was strongly affected by temperature and time. Higher temperatures accelerated the degradation of cell performance. The rates of resistance increase and power fade followed simple laws based on a power of time and Arrhenius kinetics. The data have been modeled using these two concepts, and the calculated data agree well with the experimental values. The Gen 1 calendar-life resistance increase and power fade data follow (time){sup 1/2} kinetics. This may be due to solid electrolyte interface (SEI) layer growth. From the cycle-life experiments, the resistance increase data also follow (time){sup 1/2} kinetics. But there is an apparent change in overall power fade mechanism going from 3% to 6% {Delta}SOC. Here, the power of time changes to a value less than 0.5, indicating that the power fade mechanism is more complex than layer growth. The Gen 2 calendar- and cycle-life experiments show the effect of cell chemistry on kinetics. The calendar-life resistance and power fade follow either linear or linear plus (time){sup 1/2} kinetics, depending on temperature. Temperature dependence for the kinetic law was also found in themore » cycle-life data. At 25 C, the resistance increase (and power fade) follows linear kinetics, while at 45 C, (time){sup 1/2} kinetics are found.« less
