  • Patent number: 11621414
    Abstract: A lithium metal pouch cell having a specific energy ?300 Wh·kg?1 includes an anode comprising lithium metal and an anode current collector, the anode having an areal capacity N (mAh·cm?2); a cathode comprising a cathode material and a cathode current collector, the cathode having an a real capacity P (mAh·cm?2), wherein a ratio of N/P is within a range of 0.02 to 5; an electrolyte having an electrolyte mass E and comprising a lithium active salt and a solvent, the lithium metal pouch cell having an electrolyte mass to cell capacity (E/C) ratio within a range of 1 to 6 g·Ah?1; a separator positioned between the anode and the cathode; and a packaging material defining a pouch enclosing the anode, cathode, electrolyte, and separator; wherein a protruding tab of the anode current collector and a protruding tab of the cathode current collector are external to the pouch.
