Abstract
The synthesis and the structural features of a mixed lithium titanium spinel Li4/3Ti5/3O4 obtained via a sol-gel process in nonaqueous media are reported. Electrochemical lithium insertion occurs in one reducti on process located at 1.550 V, and corresponds to the insertion of 1 L i per Li4/3Ti5/3O4 (150 A h kg(-1))in octahedral sites. During cycling experiments performed at discharge-charge rates of C/20, a stabilizat ion of the specific capacity around 105 A h kg (-1) (0.7 F mol(-1)) oc curs after the 20th cycle.
