Dry Pouch Cells with LRMOs + Cu/C for Lithium-Ion Battery, 1 Ah/pcs/pack, CLIBDPCLMROCu

Pairing the high voltage LRMO (Li1.2Ni0.13Co0.13Mn0.54O2) cathode with a Cu/C (carbon-coated on copper current collector ) in a dry pouch cell architecture represents an ultra-high-energy-density configuration for advanced lithium-ion batteries. This design leverages the extreme capacity of lithium-rich layered oxides operating up to 4.8-5.0 V vs. Li/Li+ while maximizing volumetric efficiency through a lithium metal or Cu-backed anode.

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.
