Fig. 5: Comparison of the average operating potentials of Ti-based electrode materials and charge/discharge curves for several representatives.
From: Titanium-based potassium-ion battery positive electrode with extraordinarily high redox potential
Dashed line at 2.5 V shows a tentative border between cathode (above) and anode (below) materials. Dashed line at 3.6 V designates the average potential of the K0.5TiPO4F/TiPO4F transition.
