Critical review of Design of Experiments applied to different aspects of lithium-ion batteries. Ageing, capacity, formulation, active material synthesis, electrode and cell production, thermal design, charging and parameterisation are covered.
Design of experiment (DoE) for battery test is usually the first step of ECM development. There are generally two types of DoE methods, i.e. optimal DoE and empirical DoE. Optimal DoE methods aim to optimise the load current profile to maximize parameter identifiability, which is usually measured by the Fisher information matrix. For

Overall, successful integration of computations and experiments can help to establish a predictive framework to understand the complex electrochemical processes occurring in batteries, as well as uncover important underlying trends and common guiding principles in battery materials design.
To this end, the combination of theory and experiment can help to accelerate scientific and technological development in batteries (Fig. 2) (7, 8). In particular, theory calculations can be used to guide the rational design of experiments, obviating the need for an Edisonian approach.
Two approaches have been proposed to define experiments for battery OED in literature. (1) Pre-determining sets of experiments with a combination of pulses, sinusoids, and drive cycles and (2) designing an algorithm that can generate many different experiments based on several input variables.
