Crystallization Separation TRIZ Cases
- Lithium Hydroxide Purification Using Lower Alcohol for Fluoride Removal
Lower alcohol dissolution separates fluoride from crude lithium hydroxide, enabling high-purity lithium recovery from battery waste.
- Lithium Precursor Isolation by Gas Injection and Selective Precipitation
Non-reactive gas injection and selective precipitation separate lithium from transition metals, improving recovery yield and precursor purity.
