A Comprehensive Review on Second-Life Batteries: Current State, Manufacturing Considerations, Applications, Impacts, Barriers & Potential Solutions, Business Strategies, and Policies (2019, background): “charging occurs at a constant current until a cut-off voltage is reached followed by a constant voltage charge until charging current has reduced to approximately 20 mA [64].”
Modeling of Lithium-Ion Battery Degradation for Cell Life Assessment (2018, background): “The authors of [37]–[39] concluded that αsei depends on the specific surface area of the graphite as well as on the layer formation conditions and that the value of αsei varies from 3% to 8%.”
Practical Capacity Fading Model for Li-Ion Battery Cells in Electric Vehicles (2013, background): “Furthermore, overdischarge [14], overcharge, and high C-rates [10] were also observed to enhance the capacity fading rate.”
