Third, in the present report we obtain room temperature Li-FeF3 capacities at 0.05-0.50 mA cm -2 with gel-2 (Figure and Table ) that, to the best of our knowledge, were previously only accessible at elevated temperatures (50-60°C) for solid state Li-FeF3 batteries (Table ). This point is most clearly demonstrated by comparison of our results to prior work in terms of current density (Table ) rather than C-rate (particularly for 1.0 mA cm -2 ) to account for the fact that our mass loading was ~2× higher.
