Key Findings
Electrochemical Performance:
• Energy density: ~226 Wh/kg, 634 Wh/L (349 Wh/kg_jelly (29 g) and 740 Wh/kg_NMC)
• Cycle life: >80% retention after 1,000 cycles at 1C
• High-rate stability: >70% retention at 4C; >85% retention at 2C after 1,200 cycles
• Temperature range: Stable operation between 0–50°C
Interface Analysis:
• SEI (on graphite): LiF-rich, thin, compact, thermally stable
• CEI (on NMC90): Also LiF-rich, stabilizing cathode structure even after 1,000 cycles
Safety (UN 38.3 Tests):
• Impact, shock, short circuit, thermal cycling, vibration: Passed
• No leakage, swelling, or thermal runaway observed
• Commercial cells failed or showed thermal spikes >100°C, while this cell stayed <47.75°C
