    摘要： The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system uses a reference electrode in the battery to monitor an anode potential of an anode in the battery during charging of the battery in the portable electronic device. If the anode potential falls below an anode potential threshold, the system modifies a charging technique for the battery to extend a cycle life of the battery. For example, the system may reduce a charge current of the battery if the anode potential falls below the anode potential threshold to prevent degradation caused by a negative anode potential during charging of the battery.

    摘要： The disclosed embodiments provide a battery cell. The battery cell includes a jelly roll enclosed in a pouch, wherein the jelly roll includes layers which are wound together, including a cathode with an active coating, a separator, and an anode with an active coating. To create the pouch, a first cup and a second cup are formed in a flexible sheet of pouch material based on a terrace position in the battery cell that facilitates efficient use of space within a portable electronic device. The second cup is folded over the first cup, and a terrace seal is formed at the terrace position by sealing the jelly roll in the pouch along a rim of the first and second cups.

    摘要： The invention features a prismatic battery with an electrically conductive housing comprising an elongated, prismatic can with an open end, and a housing cover pressed into the open end of the can and welded in place. The novel cover has an outer flange about its periphery, extending generally in the direction of extension of the sides of the can, which elastically deflects as the cover is pressed into the can to provide good contact for welding. The cover has two raised bumps forming internal pockets that are part of the internal volume of the cell. The bumps are also arranged to prevent rotation of the seal/vent assembly. One embodiment includes a plugged fill hole in one of the bumps. Corresponding methods of manufacture are also disclosed.

    摘要： Some embodiments of the present invention provide a system that charges a battery. During operation, the system obtains a set of charging currents {I1, . . . , In} and a set of charging voltages {V1, . . . , Vn}. Next, the system repeats constant-current and constant-voltage charging operations, starting with i=1 and incrementing i with every repetition, until a termination condition is reached. These constant-current and constant-voltage charging operations involve charging the battery using a constant current Ii until a cell voltage of the battery reaches Vi, and then charging the battery using a constant voltage Vi until a charging current is less than or equal to Ii+1.
