Abstract: Systems and methods which provide battery configurations for delivering high power while maintaining high energy density are described. Embodiments provide cylindrical batteries configured to deliver high energy density while having high power density at least in part through an electrode configuration disposing electrode material for the cathode and/or anode over an extended length of a longitudinal edge of the respective cathode or anode. An electrode configuration may provide for a continuous length of electrode material disposed along a longitudinal edge of at least one of the cathode or anode. Additionally or alternatively, an electrode configuration may provide for a plurality of electrode tabs of electrode material spaced out along a longitudinal edge of at least one of the anode or cathode.
