    摘要: A lithium-ion battery includes a cathode that includes an active cathode material. The active cathode material includes a cathode mixture that includes a lithium cobaltate and a manganate spinel a manganate spinel represented by an empirical formula of Li(1+x1)(Mn1−y1A′y2)2−x2Oz1 or Li(1+x1)Mn2Oz1. The lithium cobaltate and the manganate spinel are in a weight ratio of lithium cobaltate:manganate spinel between about 0.9:0.1 to about 0.6:0.4. A lithium-ion battery pack employs a cathode that includes an active cathode material as described above. A method of forming a lithium-ion battery includes the steps of forming an active cathode material as described above; forming a cathode electrode with the active cathode material; and forming an anode electrode in electrical contact with the cathode via an electrolyte.

    摘要: A storage voltage of a battery pack is controlled with control electronics. The storage voltage of a battery pack is sensed, and a discharge mechanism is triggered if the storage voltage is within a predetermined range of voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined range of voltage, or if the storage voltage is at or above a predetermined voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined voltage. Control electronics sense a storage voltage of a battery pack and trigger a discharge mechanism if the storage voltage is within a predetermined range of voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined range of voltage, or if the storage voltage is at or above a predetermined voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined voltage. The control electronics are coupled to an electronic device and a battery pack. The control electronics are either implemented into the electronic device or the battery pack, or in a separate control electronic device.

    摘要: A battery comprises a first terminal in electrical communication with a first electrode of the battery, a second terminal in electrical communication with a second electrode of the battery, a battery can electrically insulated from the first terminal, and at least one current interrupt device in electrical communication with the battery can. The battery can includes a cell casing and a lid which are in electrical communication with each other. At least a portion of the battery can is at least a component of the second terminal, or is electrically connected to the second terminal. The current interrupt device includes a first conductive plate in electrical communication with the second electrode, and a second conductive plate in electrical communication with the first conductive plate. The second conductive plate separates from the first conductive plate when pressure inside the battery is greater than a predetermined value, whereby a current flow between the second electrode and the second terminal is interrupted.
