Rocket Propellant: Provides High Specific Impulse.

Lithium is used as a propellant in rockets because it provides a high specific impulse, which is a measure of how efficiently a propellant generates thrust. Specific impulse is calculated by dividing the thrust produced by the propellant by the propellant's mass flow rate.

High Specific Impulse:
Lithium has a high specific impulse because it has a low molecular weight and reacts with hydrogen to produce a large amount of energy. This means that lithium-based propellants can generate more thrust per unit of mass compared to other propellants.

Lightweight:
Lithium is a very lightweight metal, which is important for rocket propellants. The lower the mass of the propellant, the more payload a rocket can carry.

Solid and Liquid Propellants:
Lithium can be used in both solid and liquid rocket propellants. Solid lithium propellants are typically composed of lithium perchlorate (LiClO4) or lithium nitrate (LiNO3) mixed with an oxidizer such as ammonium perchlorate (NH4ClO4).
