Evaluation of undoped and M-doped TiO₂, where M = Sn, Fe, Ni/Nb, Zr, V, and Mn, for lithium-ion battery applications prepared by the molten-salt method

Abstract

Bare and Fe, Zr, Sn, Mn, V and Ni/Nb doped TiO2 prepared by the molten salt method, amongst these the Zr-doped sample exhibited a stable reversible capacity.

Copper ferrites@reduced graphene oxide anode materials for advanced lithium storage applications

“…The O 1 s peak located at 530.8 eV (Fig. 2e) further confirms the formation of CuFeO 2 59 , whereas the higher binding energy peak positioned at about 532.7 eV is attributed to the surface adsorbed hydroxyl oxygen 21, 60 . The high resolution XPS spectrum of the Fe 2p doublet (Fig.…”

“…The high resolution XPS spectrum of the Fe 2p doublet (Fig. 2f) with two peaks located at 711.4 eV for Fe 2p 3/2 and 725.2 eV for Fe 2p 1/2 , is characteristic of Fe 3+   60 . In addition, the high resolution C 1 s spectrum in Fig.…”

Molten salt electrochemical synthesis of sodium titanates as high performance anode materials for sodium ion batteries

“…[24][25][26][27] Herein, for the first time, we reported a simple, fast and controllable synthesis of sires of sodium titanates (Na 0.23 TiO 2 , Na 0.46 TiO 2 , NaTi 2 O 4 ) via electrolysis of solid TiO 2 in molten salts of NaF-NaCl-NaI. Herein, a series of sodium titanates were synthesized via a simple, fast and controllable electrochemical route from solid TiO2 in molten salts of NaF-NaCl-NaI.…”
