The utilization of designed experiments is an absolute must in optimizing today’s batteries, whether it’s a need to establish the optimal mean value for a variable, set acceptable parameter ranges, reduce process waste, optimize performance based on ranking, optimize formulations for processing / performance / costs, surface response outcome modeling, or understand how variables interact and influence results. A FAST, Function Analysis System Technique, diagram is almost always recommended before attempting to define the variables to be considered in a designed experiment. Time, cost, and performance are all optimized by a thorough upfront designed approach to product design and problem solving. Today’s software can run hundreds of thousands of Monte Carlo scenarios in seconds providing insight that empirically could take months or years to establish.
