Dual functions of three-dimensional hierarchical architecture on improving the rate capability and cycle performance of LiNi0.8Co0.1Mn0.1O2 cathode material for lithium-ion battery

The lithium-ion battery is widely and increasingly used in many portable electronic devices and high-power systems in the modern society. Currently, it is significant to develop excellent cathode materials to meet stringent standards for batteries. In this paper, recent developments were reviewed for several typical cathode materials with high voltages and good capacities. These cathode materials referred to LiCoO2, LiNiO2, LiMn2O4, LiMPO4 (M=Fe, Mn, Co and Ni, et al), and their composites. The technical bottlenecks about the cathode material is required to be conquered. For instance, LiCoO2 and LiNiO2 have high coulombic capacity and good cycling characteristics, but are costly and exhibit poor thermal stability. Simultaneously, LiMn2O4 exhibit good thermal stability, high voltage and high rate capability, but have low capacity. Thus it is advantageous to produce a composite which shares the benefits of both materials. The composite cathode material is superior over any single electrode material because the former has more balanced performance, and therefore, is promising to manufacture the next generation of batteries.

Electrolyte Uptake

Fibrous membranes are promising separators for high-performance lithium ion battery because of their high porosity and superior electrolyte uptake. In this paper, the fabrication of hybrid gel polymer electrolyte (HGPE) by introducing SnO2 nanoparticles in poly(vinylidine fluoride) by electrospinning technique and soaking the electrospun nanofibrous membranes in 1 M LiPF6 in ethylene carbonate (EC)/diethyl carbonate (DEC) (1:1, v/v). The as-prepared electrospun HGPE with SnO2 nanofiller was characterized by scanning electron microscopy. The influence of SnO2 on the structure of polymer membrane, physical, and electrochemical properties is systematically investigated. HGPE shows significant high ionic conductivity 4.6 × 10[Formula: see text] S/cm at room-temperature and better cell performance such as discharge C-rate capability and cycle performance. The hybrid gel polymer nanofibrous membrane favors high uptake of lithium electrolyte so that electrolyte leakage is reduced. The gel polymer electrolyte with SnO2 filler was used for the fabrication of Li/PVdF-SnO2/LiFePO4 coin cell. The fabricated cell was evaluated at a current density of 0.2 C-rate and delivered stable and excellent cycle performance. This study revealed that the prepared HGPE can be employed as potential electrolyte for lithium ion batteries.

Maintained Discharge

Germanium (Ge) nanoparticles/multiwalled carbon nanotubes (Ge/MWCNTs) composite is synthesized by solvothermal method combined with heat treatment under H2 atmosphere. The Ge particles are buried in MWCNTs network to form expected composite. The MWCNTs not only improve the conductivity of the composite but also act as a flexible matrix to buffer the volume change of germanium nanoparticles during the process of insertion and de-insertion in lithium ion battery system. The Ge/MWCNTs composite behaves better cycle performance and higher rate capability than those of pure germanium (Ge) nanoparticles. The Ge/MWCNTs maintained discharge capacity as 1040 mAh·g-1 after 60 cycles at the current density of 100 mA·g-1. It is a promising anode material for lithium ion battery application.
