Formation no2
WebLiCoO2 (LCO) has attracted wide attention due to its high energy density, whose synthesis relies on the cobalt oxide precursor. The conventional synthetic method is featured with low yield. What is even worse, order-disorder phase transition of LCO occurs above 4.2 V, leading to structural instability and ra WebAug 15, 2024 · NO 2 is brown and N 2 O 4 is colorless. The intensity of the brown color decreases as the temperature decreases. Therefore, a decrease in temperature yields an increase in N 2 O 4. Equilibrium is shifted to the N 2 O 4 side upon a decrease in temperature. Discussion: Brown 2 NO 2 (g) ⇌ N 2 O 4 (g) Colorless
