Claim 0:
1. A device, wherein the device comprises a battery, wherein the battery comprises a battery charging port, a battery discharging port, a battery negative port, a protection integrated circuit, a control switch, and an electrochemical cell, and wherein:
the battery charging port and the battery discharging port are ports independent of each other;
the battery charging port is connected to a first electrode of the electrochemical cell, wherein a second electrode of the electrochemical cell is connected to a first end of the control switch, and wherein a second end of the control switch is connected to the battery negative port;
the protection integrated circuit is connected in parallel to electrodes of the electrochemical cell, wherein the protection integrated circuit is further connected to a third end of the control switch;
the battery discharging port is connected to the first electrode of the electrochemical cell; and
the battery charging port is connected by using a charging connection cable and the battery discharging port is connected by using a discharging connection cable, wherein the charging connection cable is of a higher specification than that of the discharging connection cable, and wherein the charging connection cable of a charging path is comparatively wider or thicker than the discharging connection cable of a discharging path to provide reduced cable impedance.
