A lithium-based energy storage system includes an electrolyte and an electrode. The electrode has a conformal coating of parylene. The parylene forms an artificial solid electrolyte interface (SEI). The electrode may include a material chosen from silicon, graphene-silicon composite, carbon-sulfur, and lithium. The use of parylene to form a conformal coating on an electrode in a lithium-based energy storage system is also disclosed.

Rechargeable aluminum ion battery

Described herein is an aqueous aluminum ion battery featuring an aluminum or aluminum alloy/composite anode, an aqueous electrolyte, and a manganese oxide, aluminosilicate or polymer-based cathode. The battery operates via an electrochemical reaction that entails an actual transport of aluminum ions between the anode and cathode. The compositions and structures described herein allow the aqueous aluminum ion battery described herein to achieve: (1) improved charge storage capacity; (2) improved gravimetric and/or volumetric energy density; (3) increased rate capability and power density (ability to charge and discharge in shorter times); (4) increased cycle life; (5) increased mechanical strength of the electrode; (6) improved electrochemical stability of the electrodes; (7) increased electrical conductivity of the electrodes, and (8) improved ion diffusion kinetics in the electrodes as well as the electrolyte.

Aqueous aluminum ion batteries, hybrid battery-capacitors, compositions of said batteries and battery-capacitors, and associated methods of manufacture and use

Systems for the production of graphene oxide sheets are provided. The systems include electro-deposition and spray deposition techniques. The graphene oxide sheets may be used as pre-cursors for the formation of porous graphene network (PGN) anodes and lithiated porous graphene (Li-PGN) cathodes. The method of making PGN electrodes includes thermally reducing a pre-cursor sheet of graphene oxide to provide a PGN anode and exposing the sheet to lithium or a lithium-containing compound to produce a Li-PGN cathode. The Li-PGN cathode and PGN anode may be combined with an electrolyte to provide an 'all-carbon' battery that is useful in various applications, such as automotive applications.

Methods of making cathodes for lithium-sulfur batteries are disclosed, in addition to cathodes and batteries containing the cathodes. A method of making a cathode is disclosed which includes extracting lignosulfonate from brown liquor, pyrolyzing the lignosulfonate, carbonizing the pyrolyzed lignosulfonate to form a carbon-sulfur compound, and forming the carbon-sulfur compound into a cathode. A cathode for a lithium-sulfur battery is disclosed which includes pyrolized lignosulfonate recovered from brown liquor, and carbon. The pyrolized lignosulfonate and carbon are suspended in a matrix having a substantially homogenous distribution of sulfur. A battery is disclosed in which an anode including an electrolye, lithium, is provided along with a membrane separate and a carbon comprising a carbon-sulfur compound derived from lignosulfonates.
