S. Bach et al., ELECTROCHEMICAL-BEHAVIOR OF A LITHIUM TITANIUM SPINEL COMPOUND SYNTHESIZED VIA A SOL-GEL PROCESS, Journal of materials chemistry, 8(1), 1998, pp. 251-253
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.
