Examples of OFADD (or OFADD components) suitable for use in the electrolyte in one or more embodiments of the present disclosure may include: (i) various unsaturated organic compounds (e.g., which may provide sites for free radical polymerization of the surface layer under reductive or oxidative conditions; such reaction within the cell may improve robustness and properties of the SEI/protective surface layer on the electrodes) or other types of initiator (or catalyst) molecules; (ii) various sulfur- or selenium-based organic additives (e.g., which may improve SEI stability or rate performance and, in the case of selenium, may improve electrical connectivity within the anode; such additives may possess higher reduction potentials than their carbonate counterparts, and therefore may form SEI on the anode at a higher potential, which may be advantageous in applications that benefit from improved SEI stability; in some examples, the addition of such compounds may result in the formation of a lithium-oxy-sulfite-comprising SEI layer); (iii) various boron-based organic additives (e.g., which may similarly improve the SEI as boron-based organic additives may decompose at higher potentials than carbonate based electrolyte components); (iv) various isocyanate-based additives (e.g., which also may improve SEI properties, for example, upon decomposition into either polyamines or polyamides or other favorable compounds); (v) various ionic compounds (e.g., which may improve SEI stability or rate performance, such as by acting as sacrificial components that may favorably tune the interfacial chemistry); (vi) various inorganic and organic salts of rare earth elements (e.g., La, Ce, Dy, Eu, Tb, Pr, etc.), magnesium (Mg), calcium (Ca) or strontium (Sr) (e.g., which may improve SEI stability and properties and cell stability and properties). It will be appreciated that certain salts noted above as optional components in the OFADD, if used in the electrolyte, may alternatively be considered part of the ADD salt or ADD salt mixture. For example, the ADD salt or ADD salt mixture may comprise Li or Mg or Ca nitrates, organonitrates, sulfides, polysulfides, sulfates, organosulfates, selenides, polyselenides, selenites, and organoselenates, some or all of which may also be used in the OFADD.
