Chloride Ion Battery Review: Theoretical Calculations, State of the Art, Safety, Toxicity and an outlook towards future developments

Batteries using chloride ions as shuttles have only been under investigation for a few years, but already several publications have dealt with this topic. In this review, we extensively report for the first time the state of the art, along with theoretical screening and calculations and an analysis of safety and toxicity. At the end, possible future approaches are evaluated.
