Primarily used as a reducing agent in organic synthesis, it facilitates the conversion of various functional groups by donating electrons. In materials science, it serves as an intercalation compound, enhancing the conductivity and mechanical properties of graphite-based materials. Additionally, it plays a role in the production of graphene and other carbon nanomaterials, where it aids in exfoliation and modification processes. Its strong reducing properties also make it valuable in battery technology, particularly in the development of potassium-ion batteries, where it can improve electrode performance.
