Electrochemical cell manufacture

摘要

A solid state electrochemical cell is made by assembling together in electrical contact an anode having lithium as its active material, a polymeric electrolyte (e.g. based on poly(ethylene oxide) and LiF3CSO3), and a cathode in the form of a composite of an insertion electrode material (e.g. V6O13) or similarly active material in combination with a polymeric material. Either before or during assembly the anode, electrolyte and cathode are heated together under pressure. This removes the necessity for applying an external pressure to the cell during cycling.
