Battery
grade lithium carbonate is a white crystalline powder that is odorless,
tasteless, and has stable chemical properties. It has low solubility in
water, but exhibits good solubility in organic solvents. In addition,
battery grade lithium carbonate has high purity, high specific surface
area, high shrinkage rate, high chemical stability, electrochemical
stability, and thermal stability. These characteristics make battery
grade lithium carbonate an ideal battery material, widely used in the
manufacturing of lithium-ion batteries.

The mechanism of action and clinical application of lithium salts in the medical field
Scope of treatment
Lithium salt drugs (such as lithium carbonate and lithium citrate) are widely used as mood stabilizers to treat mental disorders such as bipolar disorder, mania, and schizophrenia.
Working principle
By regulating the balance of neurotransmitters (such as reducing dopamine release and enhancing serotonin activity), the central nervous system achieves functional stability and suppresses abnormal neural excitability.
Clinical efficacy
Effectively alleviate the high mood, impulsive behavior, and aggressive symptoms during manic episodes, and reduce the risk of depression recurrence by 56%;
It has an improving effect on positive symptoms such as hallucinations and delusions in patients with schizophrenia.
Long term application value
Standardized use can maintain emotional stability in patients and reduce the frequency of manic depressive episodes in bipolar disorder. Some studies have shown that it may delay the progression of neurodegenerative diseases.In the field of ceramics, the addition of lithium can prepare lithium ceramics. Lithium, as a binder, makes the glaze harder and tighter, while also improving its wear resistance and impact resistance. At the same time, lithium can change the color of the glaze, resulting in a "lithium reddening reaction" that affects the redox state of the glaze, causing it to change from blue to yellow or red.
