- Treats bipolar disorder and other mood disorders.
- Helps stabilize mood swings and reduce manic episodes.
- Used as lithium carbonate or lithium citrate in psychiatric treatments.
3. Industrial & Metallurgical Applications
- Used in glass and ceramics manufacturing for heat resistance.
- Strengthens aluminum alloys for aircraft and bicycles.
- Used as a coolant in nuclear reactors.
4. Aerospace & Defense
- Lithium-based greases are used as lubricants in spacecraft and military equipment.
- Used in submarine batteries and lightweight alloys for aircraft.
Benefits of Lithium
- Essential for battery technology, making electronics more efficient.
- Effective in treating mental health disorders, improving the quality of life for patients.
- Lightweight and strong, making it ideal for industrial and aerospace applications.

Side Effects & Health Risks of Lithium
While lithium has many benefits, excessive exposure or incorrect use can lead to:
- Lithium toxicity, causing nausea, confusion, and tremors.
- Kidney damage with long-term use in psychiatric treatments.
- Weight gain and thyroid problems in some patients.
- Skin irritation and allergic reactions with direct contact.
Who Should Be Cautious?
- Individuals with kidney disease or heart problems.
- Pregnant women, as lithium can affect fetal development.
- Those on diuretics or blood pressure medications, as lithium interacts with these drugs.
Future of Lithium: Sustainable Alternatives & Recycling
- Lithium recycling is becoming more important to reduce mining impacts.
- Research is ongoing to develop alternative battery materials with similar efficiency but lower environmental impact.
- New sources like seawater lithium extraction may improve supply sustainability.
Conclusion
Lithium is a crucial element in modern technology, medicine, and industry. Its applications range from powering electric vehicles to treating mental health disorders. However, responsible use and sustainable sourcing are essential to minimize environmental and health risks.
