Batteries and Supercapacitors Aging

Electrochemical energy storage is a key element of systems in a wide range of sectors such as electro-mobility portable devices and renewable energy. The energy storage systems (ESSs) considered here are batteries supercapacitors and hybrid components such as lithium-ion capacitors. The durability of ESSs determines the total cost of ownership the global impacts (lifecycle) on a large portion of these applications and thus their viability. Understanding ESS aging is a key to optimizing their design and usability in terms of their intended applications. Knowledge of ESS aging is also essential to improve their dependability (reliability availability maintainability and safety). This Special Issue includes 12 research papers and 1 review article focusing on battery supercapacitor and hybrid capacitor aging.
