Guest Editorial Special Issue on Advanced Energy Storage Technologies and Safety Management for E-Mobility

Driven by greenhouse gas emission and resource scarcity, modern transportation is on the verge of a major paradigm shift, witnessed by the proactive penetration of electrified vehicles, vessels, and aircraft. Following this trend, energy storage systems (ESS) like batteries and fuel cells have been experiencing a booming advancement in the last decade. Furthermore, grid technologies related to ESS, such as fast charging, wireless power transfer, and vehicle-to-grid systems, have also received significant interest. However, the pursuit of the utmost user experience risks violating critical physical limits accompanied by unexpected side reactions within the ESS, resulting in efficiency reduction, quick degradation, and even catastrophic safety hazards in the most severe case. Particularly, onboard battery systems have been identified as one of the major contributors to recently reported electric vehicle fire accidents. Moreover, risks can accumulate over the life cycle and eventually spread to the second-life use.
