Capacity-fading in Lithium-Ion Battery electrode materials

Lithium-ion batteries (LIBs) are used in electronic devices for storing electrical power in mobile appliances to electric vehicles. LIBs possess interesting features like lightweight, high-energy density, small-scale size, few memory effects, long cycle life, and eco-friendliness. LIBs components include the cathode, anode, separator, collector, etc. However, the capacity of the electrode material is gradually decreases after extensive use. In this study, we perform an analysis of graphite, which is used as an anode material (theoretical capacity ~ 372 mAhg-1). The goal is to understand the atomic scales changes that trigger the capacity fade. Simulation techniques will be employed.
