Part 1: Overview of Lithium
1.1 Lithium’s Physical States and Classification
Lithium, the lightest of all metals, belongs to the group of alkali metals on the periodic table. It exhibits a silvery-white appearance and remains solid under standard conditions. As an alkali metal, lithium shares properties such as high reactivity and low density with its group counterparts. However, it stands out due to its exceptional electrochemical potential, making it indispensable in energy storage applications.
In its pure form, lithium is soft enough to be cut with a knife, yet it oxidizes rapidly when exposed to air. This reactivity necessitates careful handling and storage in inert environments. Its unique combination of physical and chemical properties has positioned lithium as a cornerstone material in modern technology.
1.2 Sources and Extraction Methods
Lithium is primarily sourced from two types of deposits: brine pools and hard rock minerals. Brine resources account for approximately 60% of global reserves but contribute only 35% to production. In contrast, hard rock mining, which represents 30% of reserves, supplies over 60% of global lithium production. This disparity highlights the untapped potential of brine resources, which could significantly enhance extraction efficiency in the future.
The global lithium mining market is projected to grow at a compound annual growth rate (CAGR) of 9.7% from 2025 to 2035. Innovations in extraction technologies, such as direct lithium extraction (DLE), aim to improve yield and reduce environmental impact. These advancements are critical for meeting the rising demand for lithium in energy storage systems.
1.3 Role of Lithium in Battery Technology
Lithium’s role in battery technology stems from its high energy density and electrochemical stability. These characteristics enable the production of lightweight, long-lasting batteries that power devices ranging from smartphones to electric vehicles.
Empirical studies have shown that lithium-ion batteries exhibit predictable degradation patterns, often analyzed using metrics like the State of Health (SOH). This metric helps manufacturers determine when a battery reaches its end of life, ensuring optimal performance and safety. Advances in lithium battery technology continue to drive innovation in renewable energy storage and electric mobility, solidifying lithium’s status as a critical material in the global energy transition.

Part 2: Physical Properties of Lithium
2.1 Melting and Boiling Points
Lithium, known as the lightest solid metal, exhibits unique physical properties that distinguish it from other alkali metals. Its melting point is approximately 180.5°C (356.9°F), while its boiling point reaches 1,342°C (2,448°F). These values are significantly higher than those of other group members, such as sodium and potassium. This difference arises from lithium’s smaller atomic size and higher ionization energy, which contribute to a more robust metallic lattice structure.
Property | Lithium | Sodium | Potassium |

The higher melting and boiling points of lithium make it suitable for applications requiring thermal stability, such as in lithium-ion batteries. These properties ensure that lithium remains stable under the high temperatures generated during battery operation, enhancing safety and performance.
2.2 Thermal and Electrical Conductivity
Lithium’s thermal and electrical conductivity further solidify its role in modern technology. As the lightest solid metal, it demonstrates excellent thermal conductivity, measured at approximately 84.8 W/(m·K). This property allows lithium to dissipate heat efficiently, a critical factor in preventing overheating in lithium-ion batteries.
In terms of electrical conductivity, lithium’s low atomic mass and high specific heat capacity (3.58 J/g·K) enable it to transport electrical charges effectively. This characteristic is vital for the rapid charging and discharging cycles required in energy storage systems.
Key Advantages of Lithium’s Conductivity:
Efficient heat dissipation reduces the risk of thermal runaway in batteries.
High electrical conductivity supports faster energy transfer, improving battery performance.

Part 3: Chemical Properties of Lithium
3.1 Reactivity with Water and Air
Lithium exhibits high reactivity, a hallmark of its chemical properties. When exposed to air, it reacts with oxygen to form lithium oxide (Li₂O), which gives the metal a dull, tarnished appearance. This reaction occurs rapidly, necessitating storage in inert environments such as mineral oil or argon gas. Additionally, lithium reacts with nitrogen in the atmosphere to produce lithium nitride (Li₃N), a compound that forms a protective layer on the metal’s surface.
When lithium reacts with water, it produces lithium hydroxide (LiOH) and hydrogen gas (H₂). This reaction is highly exothermic, releasing significant heat. The equation for this reaction is:
2Li + 2H₂O → 2LiOH + H₂↑
The high reactivity of lithium with water underscores the need for stringent safety measures during handling and storage. In lithium-ion batteries, this property is carefully controlled to prevent unwanted reactions, ensuring operational safety and efficiency.
3.2 Formation of Lithium Compounds
Lithium’s ability to form a wide range of compounds is central to its industrial applications. It reacts with halogens, such as chlorine, to produce lithium halides like lithium chloride (LiCl). These compounds are highly soluble in water and play a crucial role in electrolyte formulations for lithium-ion batteries.
