Abstract: The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a pouch enclosing the layers, wherein the pouch is flexible. The layers may be wound to create a jelly roll and/or stacked prior to sealing the layers in the flexible pouch. A side fold is also formed in the pouch by producing a target temperature in the range of 55° C. to 75° C. at a side seal of the pouch prior to folding the side seal against the battery cell.

Abstract: The disclosed embodiments provide a battery cell which includes a set of jelly rolls enclosed in a pouch. Each jelly roll includes layers which are wound together, including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a first set of conductive tabs and a second set of conductive tabs. Each of the first set of conductive tabs is coupled to the cathode of one of the jelly rolls, and each of the second set of conductive tabs is coupled to the anode of one of the jelly rolls. At least one of the first set and one of the second set of conductive tabs extend through seals in the pouch to provide terminals for the battery cell.

Abstract: The disclosed embodiments provide a system that manages use of a solid-state battery in a portable electronic device. During operation, the system monitors a temperature of the solid-state battery during use of the solid-state battery with the portable electronic device. Next, the system modifies a charging technique for the solid-state battery based on the monitored temperature to increase a capacity or a cycle life of the solid-state battery. To modify the charging technique based on the monitored temperature, the system may increase a charge rate of the solid-state battery if the temperature exceeds a first temperature threshold. On the other hand, the system may maintain the charge rate of the solid-state battery if the temperature does not exceed the first temperature threshold.

Abstract: Some embodiments provide a system that monitors a battery in a portable electronic device. During operation, the system applies a pulse load to the battery and determines an impedance of the battery by measuring a voltage of the battery during the pulse load. Next, the system assesses a health of the battery based on the impedance. Finally, the system uses the assessed health to manage use of the battery in the portable electronic device.
