Abstract
An electrochemical cell has a cell housing and an electrode assembly disposed in the housing. The electrode assembly includes positive electrode plates alternating with negative electrode plates and separated by at least one separator. An end of each of the positive and negative electrode plates includes a clear lane that is free of active material and includes an opening. An electrically conductive first inner plate extends through the openings in each positive electrode plate, and an electrically conductive second inner plate extends through openings in each negative electrode plate. The positive clear lanes are sandwiched between, and electrically connected to, the first inner plate and a first outer plate. The negative clear lanes are sandwiched between, and electrically connected to, the second inner plate and a second outer plate. The first outer plate is electrically connected to the housing, and the second outer plate is electrically connected to a terminal.
