Abstract: The present invention is directed to an electrochemical cell having plate electrodes housed inside a mating “clamshell” casing. When mated together, the casing components are form-fitting with respect to the internal battery structure so as to reduce the overall size of the electrochemical package. A header assembly containing both a glass-to-metal seal opening for a terminal lead and an electrolyte fill opening is used in conjunction with the clamshell casing. The electrolyte fill opening is constructed with an elongated opening with at least two different radii. A first and second sealing element is welded within the electrolyte fill opening at different depths within the header to block the flow of electrolyte and form a hermetic seal.

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: A pulse dischargeable electrochemical cell, preferably of a Li/SVO couple, is described. To help prevent lithium clusters from bridging to the terminal pin extending below the casing lid and connected to the cathode current collector tab, an elastomeric gasket directly contacts the inner surface of the lid. The elastomeric gasket is preferably a unitary member comprising an O-ring gasket portion that contacts the sealing glass of the glass-to-metal seal (GTMS), and a sheet-shaped gasket portion connected to the O-ring gasket portion and that contacts the inner surface of the lid. The GTMS does not have a ferrule. Instead, the sealing glass seals directly to the lid and to the terminal pin. The elastomeric gasket resides between the lid and an insulator compartment, which is described in co-assigned U.S. Pat. No. 10,629,862 to Roy et al.

Abstract: An electrochemical cell, preferably a secondary, rechargeable cell, including a casing comprised of a main body portion having opposed lower and upper open ends closed by respective lower and upper lids is described. The main body portion is composed of titanium Grades 5 or 23 having a relatively high electrical resistivity material while the lower and upper lids are composed of titanium Grades 1 or 2. The lids are preferably joined to the main body portion using laser welding. The combination of these differing titanium alloys provides a cell casing that effectively retards eddy current induced heating during cell recharging.
