Abstract: A composition comprising an active material and method for forming the same. The method for manufacturing an active material can include preparing one or more polychalcogen containing liquids, preparing a graphene nanoplatelet containing liquid, preparing an organic acid liquid, and mixing the various liquids, which can be in the form of liquids, suspensions or emulsions, to form a mixture. Additionally, the method can include filtering the mixture to produce a filtrate, and drying the filtrate to produce the active material.

Abstract: A solid-state battery comprising at least one electrode stack that includes a solid-state electrolyte, cathode, and optionally an anode. The electrolyte can be an oxygen-free and carbon-free solid-state and alkali-conducting electrolyte that is processable in oxygen-containing atmospheres with room temperature ionic conductivity greater than 1 mS/cm and room temperature shear modulus greater between 1 GPa and 20 GPa. The cathode can be composed of an electrochemically-active material from Group 16 of the periodic table having a high surface area greater than 10 m2/g and contact with a conductive carbon material. The anode can be comprised of any material that can reversibly accommodate group 1 or group 2 elements or the base group 1 or group 2 element. The solid-state battery can utilize a solid-state electrolyte having a lithium-conducting sulfide electrolyte, of the formula U6PS5X (X=Cl, Br, I) with argyrodite structure and exhibiting ionic conductivity over 1 mS cm-1 at room temperature.

Abstract: A method for coupling an electroconductive tab portion to an electrode. A foam component can first be coupled to a foil tab using any suitable method, such as ultrasonic vibration welding. The electrode material can then be mechanically pressed into the foam to couple the tab portion to the electrode. The tab portion and foam can be composed of the same material, including but not limited to a metal, such as nickel. The electrode material can be any suitable material such as lithium. The electrode material can be mechanically coupled to the foam portion by mechanically pressing the electrode material onto the foam, wherein the electrode material flows into one or more voids of the foam component.

Abstract: Carbon based electrodes for use in battery cells. The carbon-based electrodes can be a pure binderless carbon electrode. The electrode may further include a carbon nanotube-based interlayer comprising about 1-30% oxidized carbon nanotubes, wherein the interlayer can be configured to act as a secondary pathway to a current collector of a battery cell. Some of the formed cathodes can be used in battery cells including a lithium based anode and a separator formed between the cathode and anode. An electrolyte solution can be utilized to expose the cathode to an activated sulfur material.

Abstract: A silicon based micro-structured material and methods are shown. In one example, the silicon based micro-structured material is used as an electrode in a battery, such as a lithium ion battery, we have successfully demonstrated the first synthesis of a scalable carbon-coated silicon nanofiber paper for next generation binderless free-standing electrodes for Li-ion batteries that will significantly increase total capacity at the cell level. The excellent electrochemical performance coupled with the high degree of scalability rriake this material an idea candidate for next-generation anodes for electric vehicle applications. C-coated SiNF paper electrodes offer a highly feasible alternative to the traditional slurry-based approach to Li-ion battery electrodes through the elimination of carbon black, polymer binders, and metallic current collectors.
