Figure 3. TG-DSC of Li0L0 and Li0L4 powders treated with wet-dry routes. The purge gas is 80% N₂ and 20% O₂ monitoring the practical calcination and sintering under ambient air. The I~VII stages corresponded to the following reactions: I: 20~60 °C, CH₃CHOHCH₃ (l) → CH₃CHOHCH₃ (g); II: 80~230 °C, LiOH·H₂O → LiOH·0.5H₂O + H₂O (g), H₂O (Absorbed) → H₂O (g), CO₂(Absorbed) → CO₂ (g); III: 230~330 °C, Li_6.55-xH_xLa₃Zr_1.55Nb_0.45O₁₂ → H₂O (g) + Decompositions; IV: 330~500 °C, Li_6.55-xH_xLa₃Zr_1.55Nb_0.45O₁₂ → 0.5xH₂O (g) + Li_6.55-xLa₃Zr_1.55Nb_0.45O_12-0.5x, LiOH·0.5H₂O → LiOH + H₂O (g); V: 500~1,000 °C, LiOH → 0.5Li₂O + 0.5H₂O (g), Li₂CO₃ → Li₂O + CO₂ (g); VI: 150~280 °C, H₂O (Absorbed) → H₂O (g), CO₂ (Absorbed) → CO₂ (g), Li_6.55-xH_xLa₃Zr_1.55Nb_0.45O₁₂ → H₂O (g) + Decompositions; VII: 300~1,000 °C, Li₂CO₃ → Li₂O + CO₂ (g).
