Abstract: A redox cell rebalance system is provided. In some embodiments, the rebalance system includes electrochemical cell and a photochemical cell. In some embodiments, the photochemical cell contains a source of ultraviolet radiation for producing HCl from H2 and Cl2 generated by the system. The HCl product may be collected or circulated back through the system for the rebalancing of electrolytes. A rebalance cell for use in a rebalance system is also provided. In some embodiments, the rebalance cell is the combination of an electrochemical cell and a photochemical cell. In some embodiments, a source of ultraviolet radiation is housed in the cathode compartment of the rebalance cell. In some embodiments, the source of ultraviolet radiation is used to effect the formation of HCl from H2 and Cl2 present in the rebalance cell. The HCl is dissolved in aqueous electrolytes contained in the rebalance cell, which can subsequently be circulated through a rebalance system for the rebalancing of redox cells.

Abstract: A system and method for stabilizing electrodes against dissolution and/or hydrolysis including use of cosolvents in liquid electrolyte batteries for three purposes: the extension of the calendar and cycle life time of electrodes that are partially soluble in liquid electrolytes, the purpose of limiting the rate of electrolysis of water into hydrogen and oxygen as a side reaction during battery operation, and for the purpose of cost reduction.

Abstract: A method and apparatus for determining the state of charge (SOC) of a battery is discussed. The method involves measuring the terminal voltage across the battery and the current flowing through the battery at a plurality of different times and fitting a line equation with a slope and an intercept to the terminal voltage and current data. The open-circuit voltage (OCV) is calculated from the intercept of the linear equation and the SOC is determined from the OCV by reference to a lookup table.

Abstract: An electrode for use in a flow cell is presented. The electrode includes a metal plate for collecting current in the electrode that is bonded between a first and second plate.

Abstract: The multi-layer tape wrapped tubing for effectively impeding the diffusion of vapor is made in a continuous in-line process and has three distinct layers: an inner tubing layer, a middle diffusion barrier layer and an outer jacketing layer. The inner tubing layer comes into contact with liquid and vapor. Vapor that might ordinarily diffuse through the tubing is impeded by the diffusion barrier layer. The diffusion barrier layer is a laminate comprising a diffusion barrier film with a very low vapor diffusion rate sandwiched between layers of thermoplastic. The diffusion barrier layer is wrapped around the inner tubing one or more times. The outer jacket layer is a polymeric jacket which is extruded onto the diffusion barrier layer wrapped inner tubing.

Abstract: A cooling system includes a cooling unit configured to fit within a single drive bay of a personal computer. The cooling unit includes a fluid-to-air heat exchanger, an air mover, a pump, fluid lines, and control circuitry. The cooling system also includes a cooling loop configured to be coupled to one or more heat generating devices. The cooling loop includes the pump and the fluid-to-air heat exchanger from the cooling unit, and at least one heat exchanger coupled together via flexible fluid lines. The heat exchanger is thermally coupled to the heat generating device. The cooling unit is configured to maintain noise below a specified acoustical specification. To meet this acoustical specification, the size, position, and type of the components within the cooling unit are specifically configured.
