Abstract
Methods are provided for forming an electrode. The method can comprises: thermally reducing GeOpowders at a reducing temperature of 300° C. to 600° C. to produce Ge particles; mixing the Ge particles with an organic binder and a carbon source; and pressing the Ge particles with the binder and the carbon source to form the electrode. Electrodes are also provided that include a plurality of microparticles comprising Ge grains, an organic binder, and a carbon source, wherein the Ge grains comprise cubic Ge and are bonded together to form Ge particles, and wherein the Ge grains define nanopores within the electrode.
