Dry Pouch Cells with LNMO + Graphite for Lithium-Ion Battery, 1 Ah/pcs/pack, CLIBDPCLNMOG

Pairing the high-voltage LiNi0.5Mn1.5O4 (LNMO) spinel cathode with a standard Graphite anode in a dry pouch cell architecture represents a high-voltage, high-energy-density configuration for advanced lithium-ion batteries. LNMO operates at an elevated potential plateau of ~ 4.7 V vs. Li/Li+, enabling high cell-level energy density without requiring cobalt, while graphite provides a stable, low-potential negative electrode.

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.
