And now, as he lay with his face turned away, he was suddenly smitten with the terror. It came upon his heart like the grasp of claws. All the power faded from his muscles. For an instant he was no more than a dead man.

Accounting for capacity cind power fade in the battery requires the user to design the battery with the appropriate excess amounts of energy and power at BOL. Achieving rated... 

Aging is a major concern for LlBs, espedaUy for their potential near term adoption into the hybrid dectric and electric vehides (HEV/EV) sector. The demanding targets set by the United States Council for Automotive Research (USCAR) on LIB calendar hfe and cyde hfe (e.g., 15 years for 42 V battery systems and HEVs, 10 years for EVs, and 1000 cycles at 80% depth of discharge over lifetime) warrant detailed understanding of the complex, multimodal aging mechanisms, which lead to capadty decay, cell impedance rise, and power fade.
