Various embodiments herein provide methods and apparatus for conditioning a battery. The conditioning may be undertaken to restore charge capacity or power capability, especially when practiced on a battery having a lithium negative electrode and/or a positive electrode having a conversion material. In one embodiment, the conditioning method includes applying a substantially constant current or power until a conditioning voltage is reached, where the conditioning voltage is higher than the maximum voltage used during normal cycling. The method further includes continuing to charge the battery at the conditioning voltage until a maximum conditioning charge is reached. Next, the method includes discharging the battery to about the maximum charge voltage prior to using the battery in an end use. Also provided is a conditioning apparatus that is configured to perform the conditioning method. 147.-. (canceled)48. A lithium ion battery comprising:a thermally interruptible solid-state electrolyte;a positive electrode comprising lithium iron phosphate; anda negative electrode comprising lithium metal.

APPLICATION OF FORCE IN ELECTROCHEMICAL CELLS

Принадлежит: Sion Power Corporation

The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance. The application of force to the electrochemical cell has been found, in accordance with the invention, to reduce such behavior and to improve the cycling lifetime and/or performance of the cell. 159-.

APPLICATION OF FORCE IN ELECTROCHEMICAL CELLS

The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance. The application of force to the electrochemical cell has been found, in accordance with the invention, to reduce such behavior and to improve the cycling lifetime and/or performance of the cell. 159-.

An electrochemical cell , comprising:a first electrode, wherein the first electrode comprises anode active material comprising lithium metal and/or a lithium metal alloy; anda second electrode, wherein the second electrode comprises cathode active material; the electrochemical cell is under an anisotropic force having a component normal to an active surface of the first electrode; and', 'a ratio of the amount of anode active material to the amount of cathode active material is less than 5:1 on a molar basis., 'wherein61.
