I. Introduction
For many years, rechargeable Li-ion batteries (LIBs) have shown tremendous promise due to their high specific energy and power densities compared to other existing battery technologies [1]. These favorable properties, along with decreasing costs, have made LIBs the most attractive strategy for energy storage in electric vehicle (EV) and hybrid electric vehicle (HEV) applications [2], [3]. However, aging and degradation remain an impediment to widespread adoption.
