摘要： The present invention is directed to a method for analyzing the tail-end behavior of a lithium cell having a solid cathode. The tail of a longer-term accelerated discharge data (ADD) test is estimated from the tail of two shorter-term ADD tests. This is accomplished by first comparing the discharge tails of shorter-term ADD tests and determining angles or rotation that correspond to Rdc growth, and then trending rotation angles versus time to reach a give DoD. For example, the 18-month and 36-month ADD test tails are used to estimate the ADD test tail of a similarly constructed cell subjected to a longer-term ADD test, for example a 48-month ADD test.

摘要： A method for determining whether a cell will experience unacceptable voltage delay later in its discharge life before it is incorporated into a device as its power source is described. As is standard practice, the cell is first subjected to a constant resistance load discharge followed by extended elevated temperature storage and an acceptance pulse discharge. This typically depletes the cell of about 1% to 3% of its theoretical discharge capacity. According to the present invention, the cell is again stored at an elevated temperature for an extended period followed by a second pulse discharge. This second pulse discharge is to ferret out any cell that may end up experiencing unacceptable voltage delay later in its discharge life.

摘要： A single step, in situ curing method for making gel polymer lithium ion rechargeable cells and batteries is described. This method used a precursor solution consisting of monomers with multiple functionalities such as multiple acryloyl functionalities, a free-radical generating activator, nonaqueous solvents such as ethylene carbonate and propylene carbonate, and a lithium salt such as LiPF6. The electrodes are prepared by slurry-coating a carbonaceous material such as graphite onto an anode current collector and a lithium transition metal oxide such as LiCoO2 onto a cathode current collector, respectively. The electrodes, together with a highly porous separator, are then soaked with the polymer electrolyte precursor solution and sealed in a cell package under vacuum. The whole cell package is heated to in situ cure the polymer electrolyte precursor. The resulting lithium ion rechargeable cells with gelled polymer electrolyte demonstrate excellent electrochemical properties such as high efficiency in material utilization, high Coulombic efficiency, good rate capability, and good cyclability.

摘要： A hermetically sealed coin cell is described. The coin cell has the opposite polarity terminals isolated from one another by a glass-to-metal seal. Glassing a conductive disc inside a ring of greater diameter and height forms this seal. The height of the ring is equivalent to the desired height of the cell. The disc acts as one cell terminal, which can be positive or negative, and the ring serves as the other terminal. In plan view, both terminals are on the same side of the cell. This allows for easy mounting and connection to an electronic circuit board, and the like.

摘要： Improvements in the performance of lithium electrochemical cells comprising a first cathode active material of a relatively high energy density but of a relatively low rate capability, for example CFx, contacted to one side of a current collector and with a second cathode active material having a relatively low energy density but of a relatively high rate capability, for example SVO, contacted to the opposite current collector side are described. An exemplary cathode has the configuration: SVO/first current collector/CFx/second current collector/SVO, and wherein the anodic coulombic capacity does not exceed the total coulombic capacities of the SVO and CFx by greater than 25%. Manganese oxide (MnO2) is another typically used cathode active material in lieu of SVO, and the present invention is applicable to lithium cells of that system as well.

摘要： The current invention relates to the preparation of an improved cathode active material for non-aqueous lithium electrochemical cell. In particular, the cathode active material comprises ε-phase silver vanadium oxide prepared by using a γ-phase silver vanadium oxide starting material. The reaction of γ-phase SVO with a silver salt produces the novel ε-phase SVO possessing a lower surface area than ε-phase SVO produces from vanadium oxide (V2O5) and a similar silver salt as starting materials. Consequently, the low surface area ε-phase SVO material provides an advantage in greater long-term stability in pulse dischargeable cells.
