Pristine Li4Ti5O12 and Li4Ti5O12/C composite are prepared by highenergy ballmilling (HEBM)assisted solidstate reaction with TiO2 anatase and Li2CO3 or carbonprecoated TiO2 anatase and Li2CO3 as reactants. The influence of calcination atmosphere on the phase formation and particulate morphology of those two products are systematically investigated by XRD, SEM, TEM, O2TPO, and .
In the Ball Mill PM 100 this counterweight can be adjusted on an inclined guide rail. In this way the different heights of the centers of gravity of differentlysized grinding jars can be compensated in order to avoid disturbing oscillations of the machine.
