Abstract
A secondary battery includes a case, a rolled electrode assembly disposed within the case, and an electrode assembly fixing member receiving a portion of the rolled electrode assembly so that expansion and contraction of the rolled electrode assembly can be suppressed during charging and discharging operations of the battery, and deformation of the rolled electrode assembly caused by outer impact can be prevented. The electrode assembly fixing member comprises a cap fitted onto at least one of upper and lower ends of the rolled electrode assembly. The electrode assembly fixing member further comprises a gripper holding the rolled electrode assembly.

A battery comprising:
- a case;
- a rolled electrode assembly disposed within the case;
- an electrode assembly fixing member receiving a portion of the rolled electrode assembly;
- and
- wherein the electrode assembly fixing member comprises a cap close-tightly fitted onto at least one of upper and lower ends of the rolled electrode assembly.
A battery comprising:
- a case;
- a rolled electrode assembly disposed within the case;
- an electrode assembly fixing member receiving a portion of the rolled electrode assembly;
- and
- wherein the electrode assembly fixing member comprises a gripper holding the rolled electrode assembly, and the electrode assembly fixing member further comprises flat plates disposed on surfaces of the rolled electrode assembly, the gripper facing the flat plates toward the surfaces of the rolled electrode assembly so as to uniformly apply pressure over the surface of the entire rolled electrode assembly.
