摘要： An alkaline cell having a flat housing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising MnO2. The housing can have a relatively small overall thickness, typically between about 5 and 10 mm. Cell contents can be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes an insulating sealing member having a circumferential skirt which surrounds wide portions of the anode current collector. This provides a barrier between said wide portions of the current collector and the cell housing. The end cap assembly includes a vent mechanism which can activate, when gas pressure within the cell reaches a level typically between about 100 and 300 psig (6.89null105 and 20.69null105 pascal gage) The cathode can be formed of a plurality of stacked slabs having aligned hollow centers forming a central core with anode material placed therein. A separator is between anode and cathode. The housing can be of steel having a wall thickness desirably between about 0.30 and 0.45 mm.

摘要： An alkaline cell having a flat housing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising MnO2. The housing can have a relatively small overall thickness, typically between about 5 and 10 mm. Cell contents can be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes a vent mechanism which can activate, when gas pressure within the cell reaches a threshold level typically between about 100 and 300 psig (6.89null105 and 20.69null105 pascal gage). The cell can have primary and supplemental vent mechanisms such as welded or thinned regions on the surface of the housing which may activate at different pressure levels. The cathode can be formed of a plurality of stacked slabs having aligned hollow centers with an elongated opening for anode material to be inserted therein.

摘要： A freestanding, microporous polymer sheet is composed of a polymer matrix binding an electrically conductive matrix. The polymer matrix preferably includes UHMWPE, and the electrically conductive matrix preferably contains one of a carbonaceous material and a metal oxide, or a combination thereof. The UHMWPE is of a molecular weight that provides sufficient molecular chain entanglement to form a sheet with freestanding characteristics. Multiple microporous sheets can be wound or stacked in a package filled with an electrolyte to function as electrodes in an energy storage device, such as a battery or an ultracapacitor.

摘要： The invention relates to a microbattery made of bioelectroactive components based on biomimetic processes. Bio-derived electron donors and electron acceptors are separately encapsulated in at least one pair of polymerized phospholipid vesicles. Embedded within the vesicle walls are lipophilic electron mediators that facilitate the transfer of electrons across the vesicle walls. Each pair of vesicles is immobilized on a conducting surface. The pair of vesicles are isolated from each other to create a galvanic cell, in which electrons flow from high to low electrochemical potential. A high energy density battery can be achieved if the vesicles are immobilized on highly porous conducting substrates.

摘要： A new cathode design has a first cathode active material of a relatively low energy density but of a relatively high rate capability contacted to the outer sides of first and second cathode current collectors and a second cathode active material having a relatively high energy density but of a relatively low rate capability in contact with the inner sides of the current collectors. The second cathode active material has a greater peripheral extend than the current collectors and the opposed layers of the first cathode active material between which it is sandwiched. This construction helps prevent delamination by promoting improved contact of the respective active materials to the current collectors. The present cathode design is useful for powering an implantable medical device requiring a high rate discharge application.
