Systems and methods are provided, in which the level of metal ions in cells stacks and lithium ion batteries is regulated in situ, with the electrodes of the cell stack(s) in the respective pouches. Regulation of metal ions may be carried out electrochemically by metal ion sources in the pouches, electrically connected to the electrodes. The position and shape of the metal ion sources may be optimized to create uniform metal ion movements to the electrode surfaces and favorable SEI formation. The metal ion sources may be removable, or comprise a lithium source for lithiating the anodes or cathodes during operation of the battery according to SoH parameters. Regulation of metal ions may be carried out from metal ion sources in separate electrolyte reservoir(s), with circulation of the metal-ion-containing electrolyte through the cell stacks in the pouches prior or during the formation.
