An electrochemical cell includes solid-state, printable anode layer, cathode layer and non-aqueous gel electrolyte layer coupled to the anode layer and cathode layer. The electrolyte layer provides physical separation between the anode layer and the cathode layer, and comprises a composition configured to provide ionic communication between the anode layer and cathode layer by facilitating transmission of multivalent ions between the anode layer and the cathode layer.

Ionic gel electrolyte, energy storage devices, and methods of manufacture thereof

A sensing system for sensing conditions or characteristics associated with a process or thing. The sensing system includes one or more energy converters and a sensor, which are coupled to the process or thing. A node is coupled to the sensor and the energy-converter, and the node is powered by output from the energy converter. In a more specific embodiment, the node includes a controller that implements one or more routines for selectively powering a wireless transmitter of the node based on a predetermined condition. The predetermined condition may specify that sensor output values are within a predetermined range or are below or above a predetermined threshold. Alternatively, the predetermined condition may specify that electrical energy output from the energy converter is below a predetermined threshold. A remote computer may be wirelessly connected to node and may include software and/or hardware that is adapted to process information output by the sensor and relayed to the computer via the node.

Wireless sensing node powered by energy conversion from sensed system

The present invention relates to a device and method for electrolytic deposition of metals on conducting particles. The conducting particles are completely immersed in a liquid and allowed to flow across a particle contacting surface of a cathode support. The particles flow across the surface and into a reservoir. Electrical contact is made between the negative pole of a DC power supply and the conducting particles. An anode mesh is placed above and parallel to the top face of the particle bed such that the mesh does not touch the particle bed but remains a controlled distance from it. The anode mesh is connected to the positive terminal of the DC power supply. A significant aspect of the present invention is that the device does not require a separator between the particle bed and the anode.

Method of electrodepositing metal on electrically conducting particles

Zinc metal is deposited from an alkali electrolyte solution onto conductive seed particles in an electrowinning process which yields unusually high current efficiency and low energy consumption.

Efficient electrowinning of zinc from alkaline electrolytes

Molten metal is fed to a caster in a continuous casting operation through a distributor that divides the molten metal into four streams flowing in circulating patterns from the central axis of the caster. Each stream sweeps first along the longer side wall of the caster toward the corner, then back along the shorter side wall toward the center line. The result is a higher degree of fragmentation of metal crystals as they form, and a better distribution of the fragments across the caster cross section, as well as a more even temperature distribution.

Liquid metal delivery system for continuous casting

A secondary zinc air cell, or another selected metal air cell, employing a spouted/packed metal particle bed and an air electrode. More specifically, two embodiments of a cell, one that is capable of being hydraulically recharged, and a second that is capable of being either hydraulically or electrically recharged. Additionally, each cell includes a sloped bottom portion to cause stirring of the electrolyte/metal particulate slurry when the cell is being hydraulically emptied and refilled during hydraulically recharging of the cell.

Zinc metal is deposited on mobile seed particles in an electrowinning process. Exceptionally favorable results in terms of production rate, current efficiency and energy consumption are achieved by using a unique combination of design parameters and operating conditions achieved by selected ranges for particle size, current density, particle bed thickness, and acid content of the electrolyte.
