a protection circuit module comprising first and second lead plates respectively electrically coupled to the first and second electrode tabs of the battery cell;
a frame receiving the battery cell and protection circuit module;
a first cover provided on the frame;
a second cover provided under the frame; and
an IC chip is provided on the first or second cover and connected to the protection circuit module,wherein the protection circuit module comprises;
a substrate;
a protection circuit unit provided on the substrate; and
a charging/discharging terminal that is provided on the substrate and electrically coupled to the protection circuit unit,wherein an upper surface of the charging/discharging terminal is lower than an upper surface of the first cover,wherein the protection circuit module operates and processes information with the IC chip,wherein the protection circuit module further comprises an insulation layer provided on the substrate and abuts the side surface of the charging/discharging terminal,wherein the upper surface of the charging/discharging terminal is lower than an upper surface of the insulation layer,wherein the protection circuit module comprises a terminal cover configured to be opened when the charging/discharging terminal is connected to an electronic device,wherein the electrode assembly comprises;
a first electrode plate;
a second electrode plate; and
a separator, andwherein the electrode assembly is formed by interposing the separator between the first and second electrode plates and winding them together in a jelly-roll type.
