Abstract

The present work proposes a new approach to increasing the capacity of all-solid-state batteries, based on the in situ formation of an electrolyte in a Mg(BH₄)₂ electrode. Charge/discharge assessments of the electrode composed of Mg(BH₄)₂ and acetylene black showed an initial reversible capacity of 563 mA h g⁻¹-Mg(BH₄)₂.
