Schematic illustration comparing different approaches to measuring electrolyte leakage. A In the Anderson approach (no minimum or maximum leakage specified, yields R), samples may not reach an “Absolute 50%” damage point. Instead, the temperature at which “Relative 50%” damage is attained may be more meaningful. B By comparison, values of I, in the Flint approach (orange line) are zeroed, although this may not drastically displace the curve relative to an Anderson curve. C In the Lim approach, data are stretched between 0 and 100% damage, usually at the warmest and coldest temperature treatments, respectively. D Use of a liquid nitrogen control is expected to elevate all leakage values, making, for instance, an Anderson curve behave more like a Lim curve (“Absolute” and “Relative” 50% values similar), and improving generalizability among approaches
