Abstract: A self-assembled freestanding graphene membrane or graphene layer is formed from industrial graphene having a particle size from approximately 1 to 10 microns and cellulose nanofibers having a nanofiber size from approximately 1 to 9 microns. The self-assembled freestanding graphene membrane or graphene layer has a graphene to cellulose nanofiber mass ratio of approximately 12:1 to 20:1, an electrical conductivity of between approximately 5.8 and 7.2 S/cm, and a thermal conductivity of between 2000 and 3000 W m−1 K−1. The freestanding graphene membrane or graphene layer is formed from an aqueous dispersion of graphene and cellulose nanofibers in a mass ratio of graphene to cellulose nanofibers of 20:1 to 10:1 deposited on a substrate followed by self-assembly and drying. A dopant of oxygen, nitrogen, sulfur, nickel, gold, silver, zinc, copper, magnesium, and boron may be precisely incorporated into the graphene membrane or layer.

Abstract: The present invention provides a lithium metal battery having a lithium metal electrode including a cathode, an anode, a separator positioned between the cathode and the anode, an electrolyte, and a lithium metal negative electrode. The lithium metal negative electrode includes a lithium reactive metal layer, the lithium reactive metal layer being formed on a support conductive layer. A dendrite-suppressing coating is formed over the lithium reactive metal layer; the dendrite-suppressing coating is a displacement-reacted metal including silver reacted from decomposition of a silver salt and having an interface reaction product formed from a reaction between the silver salt and the lithium reactive metal layer. The interface reaction product is positioned between the displacement-reacted metal layer and the lithium reactive metal layer. The dendrite suppressing coating permits lithium metal ions to permeate the coating to react electrolytically in an overall battery reaction.

Abstract: A quasi-solid-state battery formed from non-gas evolving in-situ curing of a quasi-solid-state electrolyte that includes a high swelling polymer made from a monomer with good compatibility with liquid electrolytes, and has a good reactivity for facile non-gas evolving in-situ polymerization. The monomer can be based on acrylate polymerization chemistry or an allyl group polymerization chemistry. Non-gas evolving initiators are used for non-gas evolving in-situ polymerization of acrylate or allyl monomer-based QSE. The resulting QSE additionally has high ionic conductivity, allowing for a high battery output, and a wide electrochemical window (stable for lithium metal anode and high-voltage cathodes). The resulting quasi solid electrolyte battery is not only easy to fabricate using conventional battery manufacturing practices, the non-gas evolving in-situ polymerization causes the QSE to be uniformly distributed within the battery, ensuring high-quality, safe battery performance and longevity.

Abstract: A solventless method of making a dry electrode for an electrochemical cell is provided. A solventless electrode material mixture includes 85-99% electrode active material and from 0-10% conductive carbon additive. A polymer binder system is present from 1-15%. The polymer binder system includes one or more polymer binders. The electrode material mixture is mixed at a temperature greater than a softening point or a melting point of at least one polymer binder of the polymer binder system. The electrode material mixture is kneaded into an electrode material dough. The electrode material dough is formed into an electrode material sheet. At least a portion of the electrode material sheet is affixed to a metal current collector to form an electrode.

Abstract: The present invention provides a thin, bendable, printed, layered primary battery structure without a battery separator. The battery includes a first layer including a printed positive electrode. A second layer includes a negative electrode material which may be a printed negative electrode or a metal foil negative electrode. An adhesive, UV-curable intermediate layer is adhered to the first layer on a first side of the intermediate layer and is adhered to the second layer on a second side of the intermediate layer. The intermediate layer includes a water-soluble electroactive material and a water-soluble viscosity-regulating polymer in an amount sufficient to render the intermediate layer adhesive. The intermediate layer also includes a water-insoluble polymer matrix having sufficient rigidity to prevent contact of the first layer and the second layer. A flexible package encases the first, second, and intermediate layers.
