Chromium-substituted Li4Ti5O12 has been investigated as a negative electrode for future lithium batteries. It has been synthesized by a solid-state method followed by quenching leading to a micron-sized material. The minimum formation temperature of Li4Ti2.5Cr2.5O12 was found to be around 600 °C using thermogravimetric and differential thermal analysis. X-ray diffraction, scanning electron microscopy, cyclic voltammetry (CV), impedance spectroscopy, and charge–discharge cycling were used to evaluate the synthesized Li4Ti2.5Cr2.5O12. The particle size of the powder was around 2–4 μm. CV studies reveal a shift in the deintercalation potential by about 40 mV, i.e., from 1.54 V for Li4Ti5O12 to 1.5 V for Li4Ti2.5Cr2.5O12. High-rate cyclability was exhibited by Li4Ti2.5Cr2.5O12 (up to 5 C) compared to the parent compound. The conduction mechanism of the compound was examined in terms of the dielectric constant and dissipation factor. The relaxation time has been evaluated and was found to be 0.07 ms. The mobility was found to be 5.133 × 10−6 cm2 V−1 s−1.
