dc.description.abstract | Magnesium-ion batteries have been regarded as a promising alternative to the lithium-ion batteries due to their high theoretical capacity, relatively high potential, and magnesium abundance. However, the contradiction between the plating/stripping of Mg2+ and the electrolytes' oxidative stability has hampered the Mg-ion battery's development for energy storage applications. Here, we designed an amorphous MgO-wrapped Zn-skeleton as a unique current collector for an anode-free Mg battery to allow reversible Mg2+ plating/stripping in oxidatively stable electrolytes. The significant lattice mismatch between hexagonal Zn and MgO induces dislocations, leading to a highly defective interphase. This layer behaves as a mixed ionic-electronic conductor, rendering Mg nanoparticles upon electroplating. Combined with a large surface area, the proposed current collector considerably improved the charge transfer kinetics and lowered the cell impedance for Mg2+ plating/stripping by 1/20 of the typical Mg metal. Moreover, the Mg2+ interphase conduction was two orders of magnitude higher (similar to 10(-11) S cm(-1)) compared to the widely known passivating layer (<10(-13) S cm(-1)). This special design enables Mg-Li hybrid batteries with non-corrosive electrolytes to exhibit a high-operating-voltage of 2.82 V vs. Mg/Mg2+ and an energy density of 412.5 W h kg(-1). | - |
