    Abstract: Provided is pouch battery including an electrode assembly, and a case in which the electrode assembly is sealed and housed; the electrode assembly including a stacked structure of a sheet cathode, a sheet separator, and a sheet anode; the sheet cathode including a positive electrode active material disposed on a current collector; the sheet anode is thin conductive sheet on which lithium metal reversibly deposits on a surface thereof during discharging; the sheet anode being made of a conductive material other than lithium and having a surface substantially free from lithium metal prior to charging the battery. The pouch battery design is flexible and lightweight and provides high power density, making it a suitable replacement for conventional lithium-ion primary batteries and thermal batteries in many applications. Power can be further increased by the application of external compression. Additives and formation conditions can be tailored for forming a solid-electrolyte interface (SEI).

    Abstract: The present invention is notably directed to methods and systems for protecting a pre-charge circuit. The present invention is further directed to related computer-implemented program product. The method comprises monitoring the current flowing through the current limiting device, calculating the energy loading of the current limiting device over time, and managing the system state to prevent damaging operation of the pre-charge circuit.

    Abstract: A separator system for a LiAl/FeS.sub.x electrochemical cell includes microporous sintered metal particle retainer screens fabricated by cold compacting, tape casting or plasma spraying, followed by sintering. The separator may consist of Al.sub.2 O.sub.3 or MgO powder, AlN microporous particles, AlN microporous disk or ceramic standoff sandwiched between two screens or Al.sub.2 O.sub.3 or MgO powder plasma sprayed onto one screen surface. The various separator system combinations are impregnated with 20% to 50% by volume electrolyte salt for ionic conductivity. Pore size is less than 10 .mu.m, excluding electrode particles from reaching the separator.

    Abstract: A small to miniature pressurized secondary cell of planar configuration has a case comprising a generally cylindrical sidewall open at one end and closed at the other end by a circular end wall. The open end of the case is closed by a cover which includes a positive terminal electrically isolated from the case. A plurality of substantially rectangular positive and negative stacked electrode plates with interleaved separator components are supported within the cell to define chordal volumes between the stacked electrode plates and the cylindrical sidewall of the cell sufficient to establish equilibrium gas pressures within the cell. The positive electrode plates are connected to the positive terminal and the negative electrode plates are electrically grounded to the case. Compressible electrolyte reservoir plates can also be provided at one or both ends of the stacked electrode plates to provide additional electrolyte during the service life of the cell and to absorb expansion of the electrode stack.
