摘要:
This invention relates to the field of energy storage devices, and especially electrochemical energy storage devices including electrolytes comprising an ionic liquid, one or more solvents, and one or more salts of a Group 2 element. Effects on electrochemical performance of the electrolyte of each of the components of the electrolyte were systematically determined. In addition, interactions between the electrolytes and separator films were dissected to optimize electrochemical performance of coin cell batteries.

Preparation, characterization, and an electrochemical study of Mg0.1V2O5 prepared by a novel sol-gel method with no high-temperature post-processing are disclosed. Cyclic voltammetry showed the material to be quasi-reversible, with improved kinetics in an acetonitrile-, relative to a carbonate-, based electrolyte. Galvanostatic test data under a C/10 discharge showed a delivered capacity >250 mAh/g over several cycles. Based on these results, a magnesium anode battery, as disclosed, would yield an average operating voltage ~3.2 Volts with an energy density ~800 mWh/g for the cathode material, making the newly synthesized material a viable cathode material for secondary magnesium batteries.

摘要:
A novel silver-lithium-iodine solid-state energy device and system are disclosed. The rechargeable, self-assembled, dual-function, metal-iodide battery exhibits small size and high deliverable power. Inert until activation, the device may be stored for long periods of time. Upon activation, the device assembles the required electrochemical moieties for operation without external intervention. The device limits short-circuiting and self-discharge of the system by spontaneous reactions at the electrode / electrolyte interfaces, and thus is self-healing. By incorporating both silver and lithium in the same system, a dual function is achieved, whereby the characteristics of a lithium-based battery dominate at a low load and those of a silver-based battery dominate under a high load.

The invention describes a method of reducing or preventing the growth of microbes on the surface of an object, wherein the object is of such material that it can act as a working electrode. The method comprises the steps of providing a counter electrode, and a reference electrode. The object is used as the working electrode. Electrical current is passed through the working and counter electrodes. The current through the counter electrode is varied such that the electric potential of the working electrode is constant relative to the electric potential of the reference electrode. Also described is an apparatus for reducing or preventing microbes on an object using a potentiostatic device.
