Provided is a prismatic battery comprising stacked positive electrode plates, negative electrode plates and separator layers therebetween. The positive and negative electrode plates extend beyond a periphery of the electrode stack. The positive electrode plates are fused to form a positive current collector, and the negative electrode plates are fused to form a negative current collector. Both the positive and the negative electrode plates comprise a metal foam and are compressed between 42 and 45% of the original thickness. Also provided is a method of manufacturing the prismatic battery.
