Paving the Way towards Highly Stable and Practical Electrolytes for Rechargeable Magnesium Batteries

By Oscar Tutusaus and Rana Mohtadi

Abstract

Despite being considered a promising anode candidate for future battery technologies, the reactivity of Mg metal and its resultant passivation have challenged the development of electrolytes for rechargeable Mg batteries. In this Concept article, we shed light on critical past and current motivations, hurdles, and design strategies of electrolyte development for Mg batteries. Special focus is given to the most recent advancements; in particular, we elaborate on bottom‐up design strategies targeted to overcome the corrosion issue caused by current electrolyte systems. Salts containing the BH motif expanded the portfolio of Mg‐compatible electrolytes and are used as a platform to create a whole new promising family. Here, we explain the approach, challenges, and the path forward for ultimately creating Mg‐compatible, highly stable, and non‐corrosive Mg electrolytes.Enhancing electrolytes: A platform to design electrolytes for rechargeable Mg batteries based on the BH motif has generated a new family of highly promising and noncorrosive electrolytes. The principles that guided the design of state‐of‐the‐art Mg electrolytes and their properties are discussed. In addition, a bottom‐up design approach based on BH compounds is described
