Dry Anode-Free Pouch Cells with NCM811 + Cu for Lithium-Ion Battery, 1 pcs/pack, CLIBDAFPCNCM811C

A Dry Anode-Free Pouch Cell is a state-of-the-art battery configuration where the cell is assembled without an active anode material (like graphite or silicon). Instead, it consists only of a Cathode (e.g., SPAN), a Separator, and a Copper Foil current collector. The "Dry" designation means it has been vacuum-sealed but not yet filled with the specialized electrolyte required to facilitate the in-situ plating of lithium.

In this setup, the "anode" is created during the first charge cycle (Formation). (1) Lithium Source: All cyclable lithium resides within the SPAN cathode (or is added via pre-lithiation). (2) Electroplating: During the first charge, Li+ ions migrate through the separator and plate directly onto the bare Copper Foil. (3) Discharge: Ideally, all the plated lithium strips off the copper and returns to the SPAN matrix.

Testing Processes:

(1) Electrolyte Filling with recommended amount in glovebox.
(2) First Time Aging: 45°C, aging time ≥ 15h in an oven.
(3) Formation conditions: 45°C, 5 min rest; 0.02C constant current charging (10% theoretical capacity or 5 h); 0.1C constant current charging (30% theoretical capacity, 3 h); 5 min rest; total capacity is 40% or 8 h;
(4) Second Time Aging: 45°C, aging time ≥ 24h in a oven
(5) Battery Analyzer for charging and discharging.
