Solid state electrolyte composites based on complex hydrides and metal doped fullerenes/fulleranes for batteries and electrochemical applications

A process for manufacturing a complex hydride-C60 nanocomposite for use as an electrolyte in a battery comprising the steps of:

• dissolving a complex metal hydride and a C60 in the presence of a solvent;
• removing the solvent, thereby providing a solid-state complex metal hydride-C60 material;
• annealing the solid-state complex metal hydride C60 material at about 300° C. and in the presence of an inert gas, thereby providing a solid-state complex metal hydride-metal doped C60 nanocomposite;
• placing the solid-state complex metal hydride-metal doped C60 nanocomposite in a battery as a solid-state electrolyte to enhance a mobility of metal ions and hydrogen containing ions from the complex metal hydride within the solid-state electrolyte with the metal doped C60.
