Miniature galvanic elements - having high theoretical energy density per volume unit

摘要

Title elements comprises a negative electrode selected from Be, Al, B and U, or alloys based on these metals; a positive electrode contg. as an active material an oxide of Cu, Ag, Au or a metal of platinum gp.; and an electrolyte with conductive complex c'ions contg. oxygen (e.g. -BO3-3, PO4-3, SO4-2). The theoretical energy density of these elements amts. to 6 - 7.80 Wh/cm3. (the known zinc-mercury oxide element has an energy density of 2.55 Wh/cm3 only). These elements have constant potentials, low inner resistance, and good storage stability.
