Abstract
A transition state theory-influenced approach on maximum battery cycle-life is outlined, arriving at an ideal model of general validity. The outcome may be understood further as a thermodynamic final regularity reminiscent of Carnot-efficiency. In contrast to the common perception which attributes in blanket fashion the causality of changes in cycle-life to the engineering of battery-specific tangibles, this model allows for a more differentiated picture: That changes to battery-specific tangibles may yield differences of several hundred or more cycles is here the result of them being enhanced by a comparatively long, natural constant-based, logarithmic lever. That way such changes can cause big differences though being comparatively small to the lever base value, which emerges as a quantity of natural constants, temperature(s) and relative capacity margins but independent of battery specific energy and applied power. These are findings suggesting a revision of the current empirics-biased consensus opinion about the matter.
