Because of their characteristics, which have been continuously improved during the last years, Lithium ion batteries were proposed as an alternative viable solution to present fast-reacting conventional generating units to deliver the primary frequency regulation service. However, even though there are worldwide demonstration projects where energy storage systems based on Lithium-ion batteries are...
Electrochemical Impedance Spectroscopy (EIS) has become a popular analytical technique for research and development of battery cells' chemistries, due to the established, high precision computer controlled equipment, that are capable of direct, on-line monitoring of performance parameters or degradation of an electrochemical system. Used for Lithium-ion (Li-ion) batteries, this method allows for a...
Modern lithium-ion batteries, like LiMO2/Li4Ti5O12 chemistry, are having very high power capability, which drives the need for precise thermal modelling of the battery. Battery thermal models are required to avoid possible safety issues (thermal runaways, high-temperature gradients) but also for the optimal battery pack design and for predicting battery electrical performance during operation (especially...
