This disclosure provides systems, methods, and apparatus related to surface doping of nanostructures. In one aspect a plurality of nanostructures is fabricated with a solution-based process using a solvent. The plurality of nanostructures comprises a semiconductor. Each of the plurality of nanostructures has a surface with capping species attached to the surface. The plurality of nanostructures is mixed in the solvent with a dopant compound that includes doping species. During the mixing the capping species on the surfaces of the plurality of nanostructures are replaced by the doping species. Charge carriers are transferred between the doping species and the plurality of nanostructures.

Surface doping of nanostructures

Electrochemical devices which incorporate cathode materials that include layered crystalline compounds for which a structural modification has been achieved which increases the diffusion rate of multi-valent ions into and out of the cathode materials. Examples in which the layer spacing of the layered electrode materials is modified to have a specific spacing range such that the spacing is optimal for diffusion of magnesium ions are presented. An electrochemical cell comprised of a positive intercalation electrode, a negative metal electrode, and a separator impregnated with a nonaqueous electrolyte solution containing multi-valent ions and arranged between the positive electrode and the negative electrode active material is described.

Examples in which the layer spacing of the layered electrode materials is modified to have a specific spacing range such that the spacing is optimal for diffusion of magnesium ions are presented. An electrochemical cell comprised of a positive intercalation electrode, a negative metal electrode, and a separator impregnated with a nonaqeuous electrolyte solution containing multi-valent ions and arranged between the positive electrode and the negative electrode active material is described.

A compound of formula AMgMXor AMgM(XO)for use as electrode material in a magnesium battery is disclosed, wherein A, M, X, b', a, b, y, and z are defined herein.

Electrode materials for magnesium batteries

A magnesium battery electrode assembly is described, including a current collector comprising a metal, an overlayer material on the metal and an electrode layer comprising an electrode active material disposed on the current collector. The overlayer material passivates the metal, or inhibits a corrosion reaction that would occur between the metal and an electrolyte in the absence of the overlayer material.

Rechargeable magnesium ion cell components and assembly

A magnesium battery electrode assembly is described, including a current collector comprising a carbonaceous material and an electrode layer comprising an electrode active material disposed on the current collector.
