Abstract: A lithium electrochemical cell with increased energy density is described. The electrochemical cell comprises an improved sandwich cathode design with a second cathode active material of a relatively high energy density but of a relatively low rate capability sandwiched between two current collectors and with a first cathode active material having a relatively low energy density but of a relatively high rate capability in contact with the opposite sides of the two current collectors. In addition, a cathode fabrication process is described that increases manufacturing efficiency. The cathode fabrication process comprises a process in which first and second cathode active materials are directly applied to opposite surfaces of a perforated current collector and laminated together. The present cathode design is useful for powering an implantable medical device requiring a high rate discharge application.

Abstract: An electrochemical cell having a casing housing an electrode assembly of a separator residing between a lithium anode and a cathode comprising silver vanadium oxide and fluorinated carbon is described. The electrode assembly is activated with a nonaqueous electrolyte comprising a lithium salt dissolved in a solvent system of propylene carbonate mixed with 1,2-dimethoxyethane, lithium bis(oxalato)borate (LiBOB), and fluoroethylene carbonate (FEC). Preferably LiBOB is present in an amount ranging from about 0.005 wt. 5 to about 5 wt. %, and FEC is present in an amount ranging from about 0.01 wt. % to about 10 wt. %. This electrolyte formulation is more conductive than the conventional or prior art binary and ternary solvent system electrolytes while being chemically and electrochemically stable toward Li/SVO cells, Li-SVO/CFx mixture cells, and Li-SVO/CFx sandwich cathode primary electrochemical cells.

Abstract: The prevention of lithium clusters from bridging between the negative and positive portions of a cell during discharge is described. This is done by providing a glass wool material at an intermediate location between the casing and anode current collector of a negative polarity and the cathode current collector and the terminal pin being of a positive polarity. Typically, a lithium ion concentration gradient sufficient to cause lithium cluster formation is induced by the high rate, intermittent discharge of a lithium/silver vanadium oxide (Li/SVO) cell. However, sufficient free electrolyte necessary for normal cell function is held in the relatively large pore volume throughout the extent of the glass wool material. Moreover, permeability within the glass wool material is tortuous, which effectively increases the distance between the negative and positive surfaces of the anode and cathode. This tortuosity effectively stops “straight line” dendrite growth of lithium clusters between opposite polarity structures inside the casing.

Abstract: A miniature electrochemical cell of a primary or secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper lid. The lid has a sealed electrolyte fill port. At least one electrolyte channel in the inner surface of the lid extends radially from the fill port and outwardly beyond an outer peripheral edge of the current collector. A current collector contacts an inner surface of the lid with a first electrode active material contacting the current collector. An opposite polarity active material contacts the lower plate. A dielectric material coats the lower open end of the annular sidewall and a portion of the inner surface of the sidewall. A glass seals the dielectric material to the lower plate. An electrolyte activates the electrode assembly.

Abstract: The present invention relates to an electrochemical cell comprising an anode of a Group IA metal and a cathode of a composite material prepared from an aqueous mixture of iron sulfate, nickel sulfate, and sulfur. The cathode material of the present invention provides for a lithium electrochemical cell having an increased operating voltage and power performance with high discharge capacity as compared to a lithium cell comprising nickel disulfide cathode material. In addition, the cathode material of the present invention exhibits a smaller initial irreversible voltage loss as compared to iron disulfide. This makes the cathode material of the present invention particularly useful for implantable medical applications.
