Raw Materials Information
Lithium (Li)
Lithium is a soft, silvery-white alkali metal with atomic number 3, renowned for being the lightest metal and highly reactive. Its high electrochemical potential makes it indispensable in rechargeable batteries, including lithium-ion and lithium-polymer variants. Additionally, lithium is utilized in advanced ceramics, glass production, aerospace alloys, and nuclear fusion processes. In thin-film and sputtering applications, lithium compounds serve as critical cathode materials for rechargeable batteries.
Manganese (Mn)
Manganese is a transition metal with atomic number 25, belonging to Group 7 of the periodic table. It is a hard, brittle, silver-gray metal typically found in minerals like pyrolusite (MnO₂). Manganese enhances the hardness, stiffness, and strength of steel and other alloys, making it essential in steel production. It is also widely used in battery manufacturing, ceramics, fertilizers, and electronic materials. In advanced materials and thin films, manganese is a key component in magnetic and oxide compounds, such as Lanthanum Strontium Manganite (LSMO), which is utilized in spintronics, magnetic sensors, and memory devices due to its colossal magnetoresistance and other functional properties.
