A lithium metal thin-film battery composite structure is provided that includes a combination of a thin, stable, solid electrolyte layer [18] such as Lipon, designed in use to be in contact with a lithium metal anode layer; and a rapid-deposit solid electrolyte layer [16] such as LiAlF4 in contact with the thin, stable, solid electrolyte layer [18]. Batteries made up of or containing these structures are more efficient to produce than other lithium metal batteries that use only a single solid electrolyte. They are also more resistant to stress and strain than batteries made using layers of only the stable, solid electrolyte materials. Furthermore, lithium anode batteries as disclosed herein are useful as rechargeable batteries.

A redox flow cell is presented that utilizes a porous membrane separating a first half cell and a second half cell. The porous membrane is chosen to have a figure of merit (FOM) is at least a minimum FOM. A method of providing a porous membrane for a flow cell can include determining a figure of merit; determining a first parameter from a pore size or a thickness for the porous membrane; determining a second parameter from the pore size or the thickness that is not the first parameter for the porous membrane, based on the figure of merit; and constructing a porous membrane having the pore size and the thickness.
摘要:
A method and apparatus for the accumulation and storage of energy in electrically reversible manner wherein a two chamber electrochemical cell(a single one or part of an array of such cells) has an electrolyte of common specie solutions in the multi-chambers associated with cell electrodes and application of voltage to the electrodes causes dissimilar concentrations of ions in two chambers so that the energy is stored and reversing polarity of the electrodes allows energy discharge and normalization of concentration. Materials may be reversibly stored in the cell as solids when exceeding the solubility limits of the electrolyte, such storage being done preferably at porous electrode surfaces.
摘要:
A galvanic cell system was discovered that is based on two dissimilar electrodes in an electrolyte solution of hypochlorite and peroxide. The oxidant electrolyte solution contains preferably sodium hypochlorite and hydrogen peroxide in a 10:1 ratio. The cathode (e.g, a copper electrode) was not appreciably consumed. The anode preferably was composed of an aluminum/manganese alloy. This galvanic cell system produced significant current density (e.g., 23 mA/cm2) at a useful voltage (e.g., 1.6-1.7 V/cell). It also produced hydrogen gas, with the maximum production being approximately 1.5 moles of hydrogen per mole of expended anode material. The by-products of this fuel system were environmentally friendly products, including sodium chloride, aluminum hydroxide, and a trace of permanganate ion.
