Technological watch

A polymer-forming electrolyte can include polymer precursor(s), optional additive(s) (e.g., plasticizers; initiator; inhibitor; performance additives and/or safety additives such as nonflammable additives, flame-retardant additives, redox shuttle additives, SEI-forming additives, SEI-stabilizing additives, self-closing electrolyte additives, etc.; etc.), solvent(s) (e.g., polar solvent; salt-dissolving solvent; salt-coordinating solvent; diluent; safety solvent such as nonflammable solvent, noncombustible solvents, etc.; etc.), and/or salt(s). In some variants, the polymer-forming electrolyte can be cured (e.g., within a battery cell) to form a gel-electrolyte (e.g., between an anode and cathode of the battery cell, interspersed within the anode and the cathode, etc.).
