It consists of a planar 2D structure of hexagonal graphene sheets composed of sp 2 hybridized carbon. They are stacked together along the c-axis due to weak van der Waals forces. Lithium occupies every third layer of the structure as shown in Figure . The C-C bonds in between the planes are covalent and it leads to good intercalation for Lithium. The theoretical capacity of graphite anode in its final stage LiC6 is 372 mAh/g. The major advantages of graphite include its low cost due to abundance, non-toxicity and structural stability , , , . This low theoretical capacity limits its usage to low-power applications , , . The delithiation and lithiation results in volume changes in graphite which in turn produces stress on the electrodes. This detrimentally affects cycling stability , , . Lithium deposition on the graphite electrode is also a problem that is observed and it poses a serious safety hazard , . Lithium titanate (LTO) Li4Ti5O12 is another promising anode material for lithium-ion batteries. It crystallizes as a spinel structure and reversibly intercalates lithium at 1.55V. In the spinel structure of LTO, lithium occupies the tetrahedral sites while the octahedral voids are filled with titanium as shown in Figure . It shows a reversible capacity of around 160 mAh/g. The intercalation and de-intercalation process does not cause any major structural volume change. LTO cathode has the unique property of no SEI formation leading to low cell impedance. The major advantages of this include high safety and cycling stability. It can be summarized that the major advantages of LTO include its high cycle life, thermal stability and capacity. That is why even though it has reduced cell voltage and high cost due to the presence of titanium, it has still been commercialised , , .
