Ce and CeO2in situ modified Li4Ti5O12 with fast charge–discharge performance for lithium-ion batteries were prepared by a solid-state method. The improved performance are found to be due to the increased ionic and electronic conductivity.

In this work, we synthesized the hollowed carbon@Si cubic nanobox sandwiched by reduced graphene oxide (HC@Si@rGO) using the template-sacrificial method for lithium-ions batteries’ (LIBs’) anode with high specific capacity and ultra-stable long cyclic performance. During the preparation, the ZIF-8 was initially etched by Si(OH)4 to generate the hollowed ZIF-8 and instantaneously in-situ formation of SiO2 coatings on ZIF-8, resulting in synthesis of ZIF-8@SiO2. Afterwards, the ZIF-8@SiO2 was reduced to HC@Si by the magnesium thermal treatment while the NaCl was employed as a heat-removing agent. Successfully, the rGO was introduced coupling with HC@Si to obtain HC@Si@rGO. As anode for LIBs, it delivers high initial discharge capacity of 3712.9 mAh g[Formula: see text] at the current density of 0.1 A g[Formula: see text]. After 130 cycles, a stable specific capacity of 1311.0 mAh g[Formula: see text] is achieved. The long charge/discharge performance of HC@Si@rGO anode is demonstrated at 0.5 A g[Formula: see text], exhibiting the specific capacity of 595.4 mAh g[Formula: see text] after 500 cycles. Based on the electrochemical analysis, these remarkable performances are attributed to the unique nanostructure of HC@Si@rGO. Essentially, the inner-layered HC acts as a buffer matrix to reinforce the mechanical strength of the entire electrode and restrain the volume change of Si during the charge/discharge. On the other hand, the evenly distributed HC@Si is fixed within the flexible rGO sheets to form the network structure, which not only promises a good conductive connection between HC@Si but also prevents the continuous formation of solid electrolyte interface film.

LiMn1.5Fe0.5O4is synthesized using sol-gel method and annealed at 850°C for 24 hours. It is then characterized using X-ray diffraction (XRD) and charge discharge analysis. The bulk material are then proceed to further grinding to become nanosize. The nanosample is then characterized using XRD and charge discharge performance, and the specific capacities of the two materials are compared. nanosample of LiMn1.5Fe0.5O4shows higher specific capacity which is 160.16 mAhg-1compares to the bulk which gives only 128.663mAhg-1. This shows that with smaller particle size, the battery performance has improved in terms of its capacity.
