The further improved to 104 cm(-2), when an organic ion liquid electrolyte used.
Metallic magnesium batteries are promising candidates beyond lithium-ion batteries; however, a passive interfacial layer because of the electro-reduction solvents on Mg surfaces usually leads to ultrahigh overpotential for reversible chemistry.
