Capacity fade of Sony 18650 cells cycled at elevated temperatures

Capacity fade modelling of lithium-ion battery under cyclic loading conditions

“…The change in porosity due to charge cycle is cancelled out in the subsequent discharge cycle in case of an intercalation reaction. There is irreversible filling in the negative electrode due to the solvent reduction side reaction which is activated only in the charge cycle and absent in Ramadass et al [28]. In this study, the partial molar concentration is set to be V Li + = 13 is due to the limited internal conductivity and this term accounts for the ohmic heat in the solid phase as well as the electrolyte phase [13].…”

Enhanced Prognostic Model for Lithium Ion Batteries Based on Particle Filter State Transition Model Modification

“…The battery is considered to be in a failed state when the nominal capacity has been reduced by 20% from its nominal value. The main factors that contribute to capacity fading are: aging, temperature, and charging or discharging patterns [25,26]. The ability to predict battery capacity fade and evaluate the RUL could result in safer and more effective use of lithium ion batteries.…”

The use of battery–capacitor combinations in photovoltaic powered products

“…In applications of Li-Ion batteries, large discharge currents will generate heat which could result in an efficiency reduction of the conversion of chemical to electrical energy. Moreover this elevated temperature will cause an increase of the internal resistance and capacity fading [4,5,6,7]. Delivering large current surges is not quite the favourite use of Li-Ion batteries.…”

“…The capacitor buffer can be used for reducing the battery charge current and as a result the temperature of the battery will not surpass the critical limit during recharging. This in turn will reduce the capacity fading due to cycling at elevated temperature [5,6]. So the use of capacitors in combination with batteries could yield:…”
