Abstract: A battery cell includes an electrode assembly, a pair of electrode leads electrically connected to the electrode assembly, a battery case configured to accommodate the pair of electrode leads such that the pair of electrode leads protrude at least partially in a front and rear direction of the battery cell, the battery case having an accommodation space formed to accommodate the electrode assembly, and a taping unit configured to integrally cover both side surfaces and upper and lower surfaces of the battery case.

Abstract: Disclosed are an apparatus and a method for controlling reverse TX power in a mobile terminal. The apparatus includes a closed-loop power controller for limiting a TX power increase due to a power control bit of an RX signal by using a power-up limit bit and outputting a closed-loop power control value for decreasing the TX power when a TX power limit mode is selected, an adder for calculating a TX power by adding the closed-loop power control value and an open-loop power set using a power of the RX signal, and a maximum TX power limiter for setting a final TX power by subtracting a maximum TX power limit reference value determined according to an RX signal strength in the mobile terminal from the calculated TX power. Accordingly, it is possible to extend a call duration while accepting a rather poor call quality.
