Project Description

Iron Floride Cathode for Li Battery Technology Project
The objective of the proposed research is to advance NASA's Li-ion battery (LIB) cathode technology. Reversible conversion reactions have been demonstrated with metal sulfides, oxides, nitrides, phosphides and fluorides. Only the fluoride materials provide conversion potentials suitable for high energy capacity applications. The objective of the proposed research is to advance NASA's LIB cathode technology. Reversible conversion reactions have been demonstrated with metal sulfides, oxides, nitrides, phosphides and fluorides. Iron fluoride constitutes one of the most promising materials to maximize the energy density of Li-ion batteries. Proposed work focuses on the (1) synthesis of pre-lithiated cathode by forming a nanocomposite of LiF and Fe metal and (2) evaluating cathode electrochemical performance by cell testing. More »
