CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of non-provisional U.S. patent application Ser. No. 09/067,208 filed 28 Apr. 1998 and issued 17 May 2005 as U.S. Pat. No. 6,893,772 and entitled, "Current Collector for Lithium Electrode," which incorporated by reference provisional application 60/072,223 filed Jan. 7, 1998 entitled "SPIRALLY WOUND HIGH RATE ELECTROCHEMICAL CELL". Additionally, this application is a continuation-in-part of non-provisional U.S. patent application Ser. No. 08/430,532 to Howard et al. for "High Reliability Electrochemical Cell and Electrode Assembly Therefore" filed Apr. 27, 1995 now U.S. Pat. No. 6,051,038, which is a divisional application of U.S. patent application Ser. No. 08/155,410 to Howard et al. for "High Reliability Electrochemical Cell and Electrode Assembly Therefore" filed Nov. 19, 1993 now U.S. Pat. No. 5,439,760, and the entire contents of each are hereby incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention generally relates to a battery for an implantable medical device and, more particularly, to a current collector in a battery. BACKGROUND OF THE INVENTION [0003] Implantable medical devices (IMDs) detect and deliver therapy for a variety of medical conditions in patients. IMDs include implantable pulse generators (IPGs) or implantable cardioverter-defibrillators (ICDs) that deliver electrical stimuli to tissue of a patient. ICDs typically comprise, inter alia, a control module, a capacitor, and a battery that are housed in a hermetically sealed container. When therapy is required by a patient, the control module signals the battery to charge the capacitor, which in turn discharges electrical stimuli to tissue of a patient. [0004] The battery includes a case, a liner, and an electrode assembly. The liner surrounds the electrode assembly to prevent the electrode assembly from contacting the inside of the case. The electrode assembly includes electrodes, an anode and a cathode, with a separator therebetween. Electrolyte, introduced to the electrode assembly, is a medium that facilitates ionic transport and forms a conductive pathway between the anode and cathode. An electrochemical reaction between the electrodes and the electrolyte causes charge to be stored on each electrode. [0005] Typically, the electrode is folded. A fold may include an abrupt or a sharp bend which may affect the separator. It is therefore desirable to develop a current collector that overcomes this potential limitation.
