  • Patent number: 9742027
    Abstract: A first method for fabricating an anode for use in sodium-ion and potassium-ion batteries includes mixing a conductive carbon material having a low surface area, a hard carbon material, and a binder material. A carbon-composite material is thus formed and coated on a conductive substrate. A second method for fabricating an anode for use in sodium-ion and potassium-ion batteries mixes a metal-containing material, a hard carbon material, and binder material. A carbon-composite material is thus formed and coated on a conductive substrate. A third method for fabricating an anode for use in sodium-ion and potassium-ion batteries provides a hard carbon material having a pyrolyzed polymer coating that is mixed with a binder material to form a carbon-composite material, which is coated on a conductive substrate. Descriptions of the anodes and batteries formed by the above-described methods are also provided.

  • Patent number: 9742018
    Abstract: An electrode comprises an acid treated, cathodically cycled carbon-comprising film or body. The carbon consists of single walled nanotubes (SWNTs), pyrolytic graphite, microcrystalline graphitic, any carbon that consists of more than 99% sp2 hybridized carbons, or any combination thereof. The electrode can be used in an electrochemical device functioning as an electrolyser for evolution of hydrogen or as a fuel cell for oxidation of hydrogen. The electrochemical device can be coupled as a secondary energy generator into a system with a primary energy generator that naturally undergoes generation fluctuations. During periods of high energy output, the primary source can power the electrochemical device to store energy as hydrogen, which can be consumed to generate electricity as the secondary source during low energy output by the primary source. Solar cells, wind turbines and water turbines can act as the primary energy source.
