  • Process for producing solid electrolyte primary cell
    Patent number: 4332865
    Abstract: A process for producing a solid electrolyte primary cell comprising a lithium anode and an iodine containing cathode. In the process the cell undergoes preliminary cell discharge of at least 2 mAh per cm.sup.2 of the lithium anode surface immediately after its fabrication. Alternatively, the cell may be stored at a relatively low temperature to undergo preliminary self-discharge of at least 3 mAh per cm.sup.2 of the anode surface.
    Type: Grant
    Filed: October 2, 1980
    Date of Patent: June 1, 1982
    Assignee: Matsushita Electric Industrial Co., Ltd.

  • Solid-state lithium-iodine primary battery
    Patent number: 4315975
    Abstract: A solid-state primary cell comprising a lithium anode, a cathode comprising iodine particles not more than 77 .mu.m in diameter and a charge transfer complex of iodine with an aromatic heterocyclic compound, and a lithium iodide based solid electrolyte. The cell has an anode current collector which can be coated with a polyimide film on part of its surface for giving improved discharge characteristics to the cell.
