Electrochemical properties of spinel Li4Ti5O12 nanoparticlesnprepared via a low-temperature solid route
Original language description
Spinel phase Li4Ti5O12 (s-LTO) with an average primarynparticle size of 150 nm was synthesised via a solid state routenby calcining a precursor mixture at 600 °C. The precursor wasnprepared from a stoichiometric mixture of TiO2 nanoparticles andnan ethanolic solution of Li acetate and activated by ball-milling.nEffects of the calcination temperature and atmosphere are examinednin relation to the coexistence of impurity phases by X-rayndiffraction and 6Li MAS NMR. The charge capacity of s-LTO,ndetermined from cyclic voltammogram at a scan rate of 0.1 mV/s,nwas 142 mAh/g. The capacity of our optimised material is superiornto that of commercially available spinel (a-LTO), despite the considerablynsmaller BET-specific surface area of the former. Thensuperior properties of our material were also demonstrated byngalvanostatic charging/discharging. From these observations, wenconclude that the presented low-temperature solid state synthesisnroute provides LTO with improved electrochemical performance.
