Single inter cell electrical connections contribute to higher internal resistance of a battery and have an adverse impact on high power discharge performance and rapid recharge capabilities of the battery. Further, single inter cell connections are prone to mechanical failure, affecting battery robustness and operational safety. Another fundamental limitation of conventional single inter cell connections is non uniform current density over the plate geometry. Due to the non uniform current distribution, the portion of the grid closest to the connector corrodes more compared to the portions further away from the connector.
