“…The electrolytes are mainly lithium organic salt and the separators are usually porous films. Many researchers aim to promote LIBs to be safer, cheaper and more efficient through redesigning of cell components materials [291,292]. Lignocellulose sources have been exploited as not only porous carbon materials and binders but also as separators and electrolyte reservoirs in LIBs [235,240,293].…”

“…According to Figure b, because the silicon nanoparticles change volume, after returning to another initial state, the electrical connection between the nanoparticles, the carbon conductive material is lost, the capacity is reduced. To solve the above problem in the method shown in Figure c, amorphous silicon, which also has a stress-modulating role, is used as an adhesive to bond silicon nanoparticles so that the electrical connection is no longer interrupted and the capacity will remain [ 25 , 37 , 38 , 96 , 97 ]. In another method, nanoparticles in the field of polyaniline conductive polymer, which have both a modulating and electron conducting role, have been prepared and observed to have a good cycle life of 1000 while maintaining a capacity of 1600 mAh/g.…”

Improving the anode properties, including increasing its capacity, is one of the basic necessities to improve battery performance. In this paper, high-capacity anodes with alloy performance are introduced, then the problem of fragmentation of these anodes and its effect during the cyclic life is stated. Then, the effect of reducing the size to the nanoscale in solving the problem of fragmentation and improving the properties is discussed, and finally the various forms of nanomaterials are examined. In this paper, electrode reduction in the anode, which is a nanoscale phenomenon, is described. The negative effects of this phenomenon on alloy anodes are expressed and how to eliminate these negative effects by preparing suitable nanostructures will be discussed. Also, the anodes of the titanium oxide family are introduced and the effects of Nano on the performance improvement of these anodes are expressed, and finally, the quasi-capacitive behavior, which is specific to Nano, will be introduced. Finally, the third type of anodes, exchange anodes, is introduced and their function is expressed. The effect of Nano on the reversibility of these anodes is mentioned. The advantages of nanotechnology for these electrodes are described. In this paper, it is found that nanotechnology, in addition to the common effects such as reducing the penetration distance and modulating the stress, also creates other interesting effects in this type of anode, such as capacitive quasi-capacitance, changing storage mechanism and lower volume change.

“…Two-dimensional metal oxides are considered to be one kind of potential electrode material for high-performance LIB due to their short active paths and highly exposed active sites on the surface. However, the low electronic conductivity seriously restricts their electrochemical properties [ 1 , 2 , 3 , 4 , 5 ]. Therefore, the combination of 2D metal oxide and carbon nanosheet is an effective solution to improve the conductivity of the metal oxide [ 6 , 7 ].…”

Defect engineering is one of the effective ways to improve the electrochemical property of electrode materials for lithium-ion batteries (LIB). Herein, an organic functional molecule of p-phenylenediamine is embedded into two-dimensional (2D) layered TiO2 as the electrode for LIB. Then, the 2D carbon/TiO2 composites with the tuning defects are prepared by precise control of the polymerization and carbothermal atmospheres. Low valence titanium in metal oxide and nitrogen-doped carbon nanosheets can be obtained in the carbon/TiO2 composite under a carbonization treatment atmosphere of N2/H2 gas, which can not only increase the electronic conductivity of the material but also provide sufficient electrochemical active sites, thus producing an excellent rate capability and long-term cycle stability. The prepared composite can provide a high capacity of 396.0 mAh g−1 at a current density of 0.1 A g−1 with a high capacitive capacity ratio. Moreover, a high specific capacity of 80.0 mAh g−1 with retention rate of 85% remains after 10,000 cycles at 3.0 A g−1 as well as the Coulomb efficiency close to 100%. The good rate-capability and cycle-sustainability of the layered materials are ascribed to the increase of conductivity, the lithium-ion transport channel, and interfacial capacitance due to the multi-defect sites in the layered composite.
