Abstract:
The invention relates to a fence/railing/gate element comprising a base frame (16) that has a multiplicity of vertical bars (18; 18′) connected to a lower support profile (20; 20′; 20″; 20′″; 2″″), wherein the lengths of the vertical bars (18; 18′) are greater than the horizontal distance between two adjacent vertical bars (18; 18′). In order to extend the possible uses of such elements, it is provided according to the invention that between two adjacent vertical bars (18; 18′), in each case one flat filling element (24; 24′) is inserted for filling the space between two adjacent vertical bars (18; 18′), the height of which filling element—measured in the direction of the longitudinal extent of the lower support profile (20; 20′; 20″; 20′″; 20″″)—is greater than its width, wherein the support profile (20; 20′; 20″; 20′″; 20″″) is arranged vertically below the filling elements (24; 24′) and the region vertically above the filling elements (24; 24′) is open.
Abstract:
Advanced lithium-air cell with non-aqueous electrolyte solution is provided, having higher energy density over the prior art cells, due to protective oxygen selective permeable membrane placed over the cathode outer surface. Said membrane protects the cell from moisture and evaporation of said electrolyte, which substantially minimizes parasitic losses of lithium and increases the cell efficiency and safety.
Abstract:
Disclosed herein are electrolyte formulations containing methoxybenzene (also known as anisole or phenoxymethane) for use in lithium-air semi-fuel cells. Lithium-air semi-fuel cells contain a metallic lithium anode and an air (oxygen) fuel cell type porous carbon cathode. The reaction product in the cathode is lithium oxide (Li2O) and/or lithium peroxide (Li2O2). This reaction product is sparingly soluble in common lithium-air cell solvents, and therefore the cathode pores become blocked over time, leading to cell end-of-life. Methoxybenzene is an organic solvent that demonstrates an increased solubility of Li2O, which minimizes the clogging of the cathode. Lithium-air semi-fuel cells with electrolytes containing methoxybenzene demonstrate higher discharge capacities per the same weight, than the cells having electrolytes without methoxybenzene. Higher energy density semi-fuel cells are thus achieved.
Abstract:
Advanced lithium-air semi-fuel cell with non-aqueous electrolyte solution is provided, having higher energy density over the prior art cells, due to its protective, oxygen selective, permeable membrane of PTFE coated fiberglass cloth, placed over the cathode outer surface. Said membrane is flexible and protects the cell from moisture and evaporation of said electrolyte, which substantially minimizes parasitic losses of lithium and increases the cell efficiency and safety. The membrane may also have a layer of air-permeable adhesive added, facing said cathode.
Abstract:
Lithium metal anode protection, and various semi-fuel cell constructions for use in deep, high pressure seawater or air media are provided. The described lithium semi-fuel cells achieve record high energy densities, due to the high energy density of lithium anode and the use of the cathode reactant from the surrounding media, which is not part of the cell weight, and the use of ultralight and flexible packaging materials. These features make the described semi-fuel cells the ideal choice for powering underwater and air vehicles.
