Technical developments of anode materials for lithium ion batteries have mainly focused on graphite (natural graphite, artificial graphite, and MCMB). Anode materials such as hard carbon, soft carbon, LTO, and Si-C are still under development. Hard carbon is produced by subjecting a polymer to thermal decomposition and carbonization, yielding nongraphitizable carbon. It exhibits structural stability, safety, and excellent performance at low temperature; moreover, batteries made of hard carbon have a long charge/discharge cycle life. Therefore, hard carbon is suitable for use in Li–ion batteries for electric cars that emphasize output power. This study developed a hard carbon anode by using phenolic resins that were ground to powders with a particle size (D50) of approximately 8 μm. Subsequently, the powders were heat treated at temperatures from 900°C to 1300°C for carbonization to reduce the specific surface area (SSA) of hard carbon. However, the SSA was determined to be still larger than that stipulated in commercial specifications. Therefore, this study coated the hard carbon with 1.5 wt.% poly (dimethyldiallylammonium chloride) and 1.5 wt.% poly (sodium-p-styrenesulfonate) to further reduce its SSA. The results indicated that 1st discharge capacity of the coated hard carbon was 330 mAhg−1. Its 1st irreversibility was reduced from 24.3% to 8.1% and SSA was reduced from 10.2 to 2.8 m2g−1; additionally, its coulombic efficiency after 20 cycles was over 99%. The cycle performance of the double-coated hard carbon at low temperature (-20°C) was improved, and it satisfies high C-rate (10 C) requirements.

Ion Insertion

Two prelithiation processes (shallow Li-ion insertion, and thrice-repeated deep Li-ion insertion and extraction) were applied to the hard carbon (HC) negative electrode (NE) used in lithium-ion batteries (LIBs). LIB full-cells were assembled using Li(Ni0.5Co0.2Mn0.3)O2 positive electrodes (PEs) and the prelithiated HC NEs. The assembled full-cells were charged and discharged under a low current density, increasing current densities in a stepwise manner, and then constant under a high current density. The prelithiation process of shallow Li-ion insertion resulted in the high Coulombic efficiency (CE) of the full-cell at the initial charge-discharge cycles as well as in a superior rate capability. The prelithiation process of thrice-repeated Li-ion insertion and extraction attained an even higher CE and a high charge-discharge specific capacity under a low current density. However, both prelithiation processes decreased the capacity retention during charge-discharge cycling under a high current density, ascertaining a trade-off relationship between the increased CE and the cycling performance. Further elimination of the irreversible capacity of the HC NE was responsible for the higher utilization of both the PE and NE, attaining higher initial performances, but allowing the larger capacity to fade throughout charge-discharge cycling.

Carbon Anodes

Lithium-ion batteries are widely used in various industries, such as portable electronic devices, mobile phones, new energy car batteries, etc., and show great potential for more demanding applications like electric vehicles. Among advanced anode materials applied to lithium-ion batteries, silicon–carbon anodes have been explored extensively due to their high capacity, good operation potential, environmental friendliness and high abundance. Silicon–carbon anodes have demonstrated great potential as an anode material for lithium-ion batteries because they have perfectly improved the problems that existed in silicon anodes, such as the particle pulverization, shedding and failures of electrochemical performance during lithiation and delithiation. However, there are still some problems, such as low first discharge efficiency, poor conductivity and poor cycling performance, which need to be improved. This paper mainly presents some methods for solving the existing problems of silicon–carbon anode materials through different perspectives.

Partial Destruction

Abstract The paper is devoted to the study of the effect of thermal annealing on the change in the structural properties and phase composition of metal Co nanostructures, as well as the prospects of their use as anode materials for lithium-ion batteries. During the study, a four-stage phase transition in the structure of nanowires consisting of successive transformations of the structure (Со-FCC/Co-HCP) → (Со-FCС) → (Со-FCC/СоСо2О4) → (СоСо2О4), accompanied by uniform oxidation of the structure of nanowires with an increase in temperature above 400 °C. In this case, an increase in temperature to 700 °C leads to a partial destruction of the oxide layer and surface degradation of nanostructures. During life tests, it was found that the lifetime for oxide nanostructures exceeds 500 charge/discharge cycles, for the initial nanostructures and annealed at a temperature of 300 °С, the lifetimes are 297 and 411 cycles, respectively. The prospects of using Co/CoCo2O4 nanowires as the basis for lithium-ion batteries is shown.
