Mixed oxides of titanium and niobium (TNO) are considered as safe anode materials for lithium-ion batteries with long cycling life. Such benefits are associated by both structural stability and relatively high working potentials of Ti(IV)/Ti(III) and Nb(V)/Nb(IV) redox couples (1.3 – 1.6 V vs. Li/Li+) preventing SEI formation. An additional attention has been attracted to HTiNbO5 as the unique proton-containing anode material providing reversible capacity of 120 mAh·g−1 after 50 cycles. However, no detailed studying of Li+ (de)intercalation in HTiNbO5 can be found up to date. This work is devoted to synthesis and investigation of HTiNbO5 as an anode material for LIB’s. The work was supported by the Russian Science Foundation (grant №. 17-73-30006-11).
