Random and uncertainty analysis of cylindrical alkaline cells

A method is presented to analyze the performance of a cylindrical Zn–MnO2 alkaline cell with parameter randomness and uncertainties. Two kinds of parameters are recognized with different random and uncertain characteristics. These are parameters with randomness such as the particle size, and parameters with uncertainties such as kinetic and transport coefficients. A sampling procedure based on a differential-algebraic equation model of the alkaline cell is developed to simulate a cellʹs statistical performance. A numerical example is illustrated with an AA-size cell under a 1 A constant current discharge.
