Electrochemical intercalation of lithium in the titanium hydrogeno phosphate Ti(HPO4)2·H2O

Titanium phosphates as positive electrode in lithium-ion batteries: composition, phase purity and electrochemical performance

“…By increasing the P/Ti molar ratio, the first two plateaux (Fig. 5d), raising a discharge and charge plateau of 2.6 V which is consistent with previous work [10,56,63] or even slightly shifted from these values [64].…”

A Mesoporous Iron‐Based Fluoride Cathode of Tunnel Structure for Rechargeable Lithium Batteries

“…Note that we refer to voltages above 1.6 V where the conversion reaction does not occur and the water is obviously not reduced. Recently, hydration water frequently appeared as structural adjuster in the field of battery materials in the context of oxide and phosphate cathodes 16–19. A remarkable example is the hydration‐water‐containing iron phosphate, which shows improved electrochemistry 17, 18.…”

Hybrid supercapacitor with nano-TiP2O7 as intercalation electrode

“…Among them, Li 4 Ti 5 O 12 used as negative electrode (anode) is found to show very good HEC characteristics [8]. Titanium pyrophosphate, TiP 2 O 7 has been studied as a Li-insertion host for the past few years which showed the reversible insertion and extraction of ~0.8 mole of Li per formula unit at a voltage of 2.6 V vs. Li [23][24][25][26][27]. To the best of our knowledge, TiP 2 O 7 has not been studied in HEC configuration.…”
