Abstract
Salts with formula X−M+ wherein M+ is Li, Na, K, an ammonium, a phosphonium, an imidazolium, a pyridinium, or a pyrazolium and X− is an anion formed from covalent linking of two negative moieties to a positive onium-type core are provided. Also provided are electrolytes and batteries produced from these salts.
