Abstract
A high discharge rate electrochemical battery structure is disclosed as having a perforated disc electrode stack comprising pluralities of disc electrodes respectively connected to a pair of busbars. Each disc electrode has a tab with two fins which are bent at 90 degrees to the disc electrode. Each fin is inserted between two parts of the corresponding busbar and welded thereto. The design of the busbars and disc electrodes provides for redundancy of electrical contact, high thermal and electrical conductivity and improved resistance to mechanical shock.
