Secondary battery with electrode assembly fixing device |
摘要 |
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.
