Electrical Drives, Automation and Motion Energy storage battery aging: general methodology and examples of application

The paper describes a wide and complete methodology for the execution of aging tests and the analysis of aging mechanisms of electrochemical accumulators, whose purpose is to extend the lifetime of the energy storage systems through a non-stressful management of the battery and through improvements at level of cell materials. The methodology has been applied to three lithium-ion cells and the results are summarized and commented in the paper.
