Nonlinear Structural Model of the Battery

A nonlinear structural model of the battery that can be used for modeling the operation of alkaline, acid, and lithium-ionic batteries is constructed. This model retains all the advantages of traditional structural models: namely, it contains as many parameters as can be determined from experimental studies for the battery as a whole. This model, as well as all structural models, is graphic and understandable from both electrochemical and electrotechnical points of view. However, the proposed nonlinear structural model can be used for modeling the operation of the battery at high currents that are usually found in various modes of their operation. This is the main difference between the given model and traditional structural models which are used only in the theory of an impedance, that is, during the use of small alternating currents.
