Summary: Lithium-Ion Batteries (LIBs) are crucial for saving oil and reducing exhaust emissions in applications such as electric vehicles and electronic devices. Lithium titanate (LTO) is a promising anode material with reversible Li-ion extraction and low volume change during Li transmission. However, LTO has limitations that can be improved through doping. This report reviews the doping of LTO with various dopants and different fabrication methods.

Summary: Ga2O3 is widely used as anode material for lithium-ion batteries due to its high theoretical capacity. However, it has limited electronic conductivity and severe volume expansion, which restrict its application. In this study, Ga2O3 nanospheres were coated with carbon to improve overall electrochemical performance. The carbon coating treatment not only shortened ion transmission path and improved cycle stability but also provided abundant lithium-ion storage space, resulting in high pseudocapacitive storage characteristics.

Summary: In order to pursue sustainable developments, this study investigates the application of poly(N-vinylformamide) (PNVF) as a green, bio-derived and water-soluble binder for Li4Ti5O12 (LTO) anode in lithium-ion batteries (LIBs). The electrochemical performance differences between PNVF electrodes and conventional polyvinylidene fluoride (PVDF) electrodes are presented. The results demonstrate that the electrode with 3 wt% PNVF shows higher peeling force and better cycle performance compared to the one with 10 wt% PVDF. Additionally, the optimal PNVF electrode exhibits lower electrochemical impedance and higher lithium-ion diffusion coefficient.

Summary: Despite the development of various anode materials, graphite remains dominant due to its excellent cyclic performance. However, there is a need to boost the energy and power capacities of lithium-ion batteries (LIBs) for electric and hybrid cars. Carbon nanostructures have been anticipated as a solution, but their widespread use is still in its infancy due to low densities. This review focuses on recent developments in creating LIBs with enhanced capacity, rate performance, and cyclic stability using carbon nanostructure-based anodes.
