ULTRAHIGH ENERGY ELECTROCHEMICAL POWER SYSTEMS BASED ON SAFE FLUORINATED REACTANTS
Abstract
This work proposes to develop the reactant chemistry and energy conversion fundamentals underpinning a new type of primary electrochemical energy system based on liquid fluorinated reactants (LFR), which are pursued with the aim of creating batteries capable of greater than1000 Wh-kgcell. The leading merits of the reactions to be developed are- i) Theoretical specific energies exceeding today’s leading primary battery chemistries; ii) High safety—intrinsic to the nature of the reactants to be studied and their conversion pathways—which cannot be met by existing technologies; iii) Unprecedented degrees of versatility unlocked by a new molecular design space. These characteristics address a variety of important problems at the forefront of advanced energy conversion science, such as molecular underpinnings of electrochemical activity in emerging chemistries, multi-electron reactions (ngreater than4 electrons-molecule with a target of greater than10), new reactivity modes unlocked by these chemistries, and the elucidation of physicochemical handles within the extended reaction environment of the electrolyte to manipulate energy and power. This work will build foundational knowledge needed to design technologies that address critical performance gaps for aircraft electrical power, UAV, and robotics platforms, where the strategic advantage lies in identifying new chemistries rather than iteratively improving existing ones.
