🔬 Understanding the Thermal Decomposition of Lithium Hydroxide Monohydrate (LiOH·H₂O)
As demand for battery and new energy materials continues to grow, controlling the thermal behavior of lithium compounds becomes increasingly critical.
Lithium hydroxide monohydrate plays a key role in cathode material production, and its dehydration and decomposition directly affect:
✔ Sintering temperature design
✔ Lithium stoichiometry control
✔ Material purity
✔ Process stability
Based on STA analysis under oxygen atmosphere (25–800°C, 5°C/min), the transformation pathway can be summarized as:
📌 31.8–130.3°C – Dehydration (~11.31% weight loss)
📌 198.9–456.4°C – Critical decomposition zone (~12.53% weight loss)
📌 >600°C – Li₂O enters a relatively stable region
Precise temperature control in the 200–450°C range is especially important to prevent lithium loss and composition deviation during cathode material processing.
