Abstract
(EN)
Provided herein are rechargeable alkali metal batteries comprising: an anode including an alkali metal; a cathode; and an electrolyte to support reversible plating and stripping of the alkali metal at the anode, wherein the electrolyte includes alkali metal ions, chloroaluminate anions (AlClri), and an additive including imide anions.
(FR)
La présente invention concerne des batteries à métal alcalin rechargeables comprenant : une anode comprenant un métal alcalin ; une cathode ; et un électrolyte pour supporter le placage réversible et le décapage du métal alcalin au niveau de l'anode, l'électrolyte comprenant des ions de métal alcalin, des anions de chloroaluminate (AlClri) et un additif comprenant des anions imide.
