An electrode morphology and architecture for energy storage applications that increases the rate of charge/discharge, battery life, and decreases cost. The morphology and architecture directed towards a method and apparatus incorporating a graphene supported anode including a substrate, a vertically oriented graphene support arrangement coated with silicon or the like, in an electrolyte.

Vertically oriented graphene-supported anode

A solid state energy storage device has two electrodes, a membrane separator and a solid electrolyte having a substantially solid solvent, a salt and a mediator. The energy storage device stores electric charge by both Faradaic and non-Faradaic systems. The energy storage device may include activated carbon mixed with the electrolyte and sonicated to provide connection between the activated carbon and the mediator. The energy storage device is hot pressed to increase conductivity. The two electrodes may be asymmetric in amount of reduced and oxidized species of mediator.

Solid state energy storage device and method

A film of nickel oxide is anodically deposited on a graphite sheet held in osition on an electrochemical cell during application of a positive electrode voltage to the graphite sheet while exposed to an electrolytic nickel oxide solution within a volumetrically variable chamber of the cell. An angularly orientated x-ray beam is admitted into the cell for transmission through the deposited nickel oxide film in order to obtain structural information while the film is subject to electrochemical and in-situ x-ray spectroscopy from which optimum film thickness, may be determined by comparative analysis for capacitor fabrication purposes.

Electrochemical fabrication of capacitors

The shelf life of electrochemically prepared AgO cathodes is improved by reasing the temperature of anodization step to about 70.degree. C. or higher. At these elevated temperatures the capacity of the AgO electrode can also be increased by using a charge-discharge-charge regime.
