Lithium-ion batteries(LIBs) have been widely used in portable electronic devices and electric vehicles owing to their characteristics of high energy density, safety, and long lifetime. Titanium dioxide(TiO2) is a promising anode material for LIBs due to the advantages of non-toxicity, low cost, abundant sources, and stable chemical structure. However, intrinsic low electronic conductivity and poor lithium-ion(Li+) diffusion have restricted its development for practical applications. In this review, we firstly systematically summarize the lithium storage mechanisms of three common TiO2 polymorphs, that is, a two-phase solid solution of anatase TiO2, intrinsic pseudo-capacitance of TiO2(B), and potential-dependent phase transition of rutile TiO2. Furthermore, to enhance the electron conduction and Li+ diffusion, the research progress of nanostructure dimensional tailoring, intrinsic/extrinsic electronic structure manipulation(elemental doping, Ti3+ self-doping, and modification of highly conductive materials), and hetero-phase junction optimization are discussed in detail. Finally, the development trend and application prospect of TiO2 anode materials for LIBs and beyond-LIBs are proposed.

The rapid development of electric vehicles and large-scale energy storage systems have created a huge demand for high energy density and power density lithium-ion batteries in the market. Because of the advantages such as high voltage(4.7 V vs. Li/Li+), high energy density and power density, abundant resources and low cost, LiNi0.5Mn1.5O4 is considered as one of the most promising lithium-ion battery cathode materials.

As a kind of green rechargeable battery with high energy density and power density, lithium-ion batteries are the first choice of portable electronic products and are gradually applied in the field of power vehicles. In order to better meet application requirements, it is necessary to further improve the energy density of current lithium-ion batteries.

Lithium-rich manganese-based layered cathode materials (xLi2MnO3·(1-x)LiMO2, M=Ni, Co, Mn, etc.), owing to their high specific capacity (≥ 250 mAh·g-1), low cost and environmental friendliness, are considered as one of the best candidate cathode materials for the new generation of lithium-ion batteries.

In this paper, we analyze the structural characteristics and the reasons which lead to the deterioration of the electrochemical performance of the lithium-rich manganese-based layered cathode materials, systematically review the latest progress and achievements on improving the stability of the cathode materials, and the efforts to improve the electrochemical properties of the cathode materials through bulk doping and surface modification. In this process, the effects of bulk doping at different sites and different coating materials on the structure and electrochemical behavior of lithium-rich manganese-based layered cathode materials are further analyzed. Finally, considering the advantages and disadvantages of the two modification methods of bulk doping and surface coating, a joint modification mechanism combining bulk doping and surface coating has been suggested to improve the stability of lithium-rich cathode materials in the long cycle process, and the introduction and prospect of this mechanism are also given.

With the commercial application of low specific capacity silicon-carbon composites(<500 mAh/g) in lithium-ion batteries, silicon-based anode materials have also evolved from laboratory research to industrialization. In recent years, various investigations have been proposed to solve the problems caused by the volume change (>300%) of silicon during lithiation/delithiation. From the perspective of material structural design, the research focus has gradually shifted from the initial silicon nano-structuration and elaboration of silicon-based composite materials to the structural design of the silicon-carbon composite secondary particles and the surface coating design. In terms of application performance research, in addition to specific capacity and cycle performance of materials reported in the early literature, the specific surface area, tap density, initial and cyclic coulombic efficiency and other parameters of materials which are more in line with the practical application requirements of the batteries have been widely studied, thus greatly promoting the commercial application process of the silicon-based anode materials. In this review, the development of the composition and structural design of silicon-carbon composites in recent years are presented and summarized. The structural characteristics and electrochemical properties of silicon-carbon composites synthesized by graphite, soft carbon, hard carbon, carbon fiber and graphene as carbon sources are further proposed and compared. Moreover, the effects of carbon in the structure and properties of silicon-carbon composites are briefly summarized.

As the secondary battery with the highest specific energy, lithium ion battery is widely used in portable electronic devices, new energy vehicles and large-scale energy storage power stations. Currently, commercial lithium-ion batteries are facing some technical bottlenecks, such as low energy density and short service life. There are many reports about the anode materials of lithium ion batteries, but most of them cannot overcome the shortcomings such as the huge volume expansion before and after lithium, the pulverization of electrode materials, and the large electrode impedance. However, metal oxides derived from metal-organic frameworks(MOFs) and composites are widely used in lithium ion batteries due to their low level charge-discharge potential platform, high capacity and stable cycle performance. Therefore, in this paper, metal oxides derived from MOFs and composites are divided into four modules: mono-metal oxides, bi-metal oxides, bi-component metal oxide composites and metal oxide/carbon composites. The relationships between their synthesis methods, morphologies and electrochemical properties are summarized, and the opportunities and challenges for their future development are forecast.

With the continuous improvement of the requirements for the power of lithium-ion batteries in electrical vehicles, high-performance lithium-ion batteries are becoming the focus of researchers. As one of the critical components in lithium-ion batteries, membranes play the role of separating the anode and cathode materials and providing the channels for lithium ions to translate. In addition, the thermal stability of membranes can affect the safety of batteries directly. Polyolefin microporous membranes are widely used in lithium batteries for their excellent chemical stability, high mechanical strengths and low cost. However, the poor thermal stability and wettability bring great hidden danger to the wide application of high-performance lithium-ion batteries. As a result, starting from the surface modification of polyolefin microporous membranes, the paper introduces the research progress of polyolefin microporous membranes which are based on polymer surface modification and inorganic nanoparticles, organic-inorganic composites. When introducing the polyolefin microporous membranes based on inorganic nanoparticles, the paper makes a brief introduction to those advanced surface modification methods such as atomic deposition, the chemical vapor deposition method and the physical vapor deposition method. Subsequently, based on the shortcomings of polyolefin, the research progress of other polymer microporous membranes are introduced with respect to the wet process, the phase inversion method, the breath figure method, electrospinning and the in-situ polymerization. At last, the paper makes an outlook for the future researches of high-performance membranes and means to provide a reference for the research and application of high-performance membranes in lithium-ion secondary battery membranes.

Increasing the voltage is one of the important ways to improve the energy density of lithium ion batteries. For example, LiNi0.5Mn1.5O4 (4.7 V), LiNiPO4(5.1 V) and lithium-rich manganese-based materials exhibit high energy density and low cost at high charge cut-off voltage, showing good application prospects. In addition, increasing the charge cut-off voltage of LiCoO2 and NMC battery systems is a simple and effective approach to increase the energy density. However, when the charge cut-off voltage is increased, not only the electrolyte will be oxidatively decomposed at the cathode /electrolyte interface, but also the dissolution of the metal cation from the cathode materials will be accelerated. These are the main causes for the decreased cycle stability and safety. The electrolyte additives can be used for modifying positive electrode interfaces, thus passivating the cathode/electrolyte interface and inhibiting the decomposition of the electrolyte. Moreover, the modified electrolyte can effectively suppress the destruction of the cathode structure. Based on the molecular structure of the additives, the related research results of additives such as sulfonate ester, boric acid ester, phosphate ester, fluorocarbonate, nitrile, anhydride and lithium salt at the positive electrode interface are introduced in this paper. The action mechanisms of different additives are explained and generalized. Furthermore, the combination technology of additives for different batteries are introduced. At last, the development of new electrolyte additives for cathode/electrolyte interface modification are discussed.

Lithium ion batteries(LIBs) have been widely used as the energy storage system for the applications of the laptop, the communication equipment and the consumer electronics. And importantly, it will be largely used in the electrical vehicles in the near future. Silicon with a high theoretical capacity of 4200 mAh·g-1(more than 10 time of current graphite anode) is one of the most promising alternative anode material for the next generation of LIBs. However, the electrode pulverization, continuous growth of solid electrolyte interphase(SEI) and lithium consumption in silicon anode material based batteries usually happen during charge/discharge process due to its huge volume change. Moreover, the weak interaction between conventional binder and silicon anode material results in the continuous separation of silicon active material. These problems severely hinder the practical application of silicon anode material. This review systematically summarize the recent progress of silicon and its related materials for LIBs. The content includes the fabrication of silicon materials, the structure of silicon materials, binders, electrolytes and electrolyte additives. Finally, the future development direction of silicon-based materials is presented.

Silicon is expected to replace graphite as the next-generation anode material for lithium-ion batteries because of its high theoretical specific capacity. But the huge volume expansion (~300%) of silicon during lithiation/delithiation process will cause active substance pulverization and loss contact with current collector, and continuous formation of solid electrolyte layer will further result in irreversible capacity fading. It has been demonstrated that nanocrystallization and carbon coating are effective ways to overcome these problems. In this paper, the mechanism of capacity fading of silicon is introduced, and the latest research on the synthesis of Si nanoparticles and carbon composites is reviewed, mainly including coating, core-shell and embeded silicon/carbon anode materials. The core-shell and embedded type are specifically reviewed. Finally the problems of the Si nanoparticles/carbon composites are analyzed and the prospects for research are prospected.

Li4Ti5O12 as anode materials for lithium ion batteries has been widely studied because of its excellent rate performance and cycle performance, but the low specific capacity (175 mAh/g) limits its application in the future. Compared with Li4Ti5O12, niobium based oxides have similar lithium ion insertion/extraction potential and higher specific capacity. In addition,they also have good rate performance and promising to be new anode materials with high power performance, that have got increasing researchers' attention in recent years. In this paper,the crystal structure, electrochemical performance and lithium ion insertion/extraction mechanism of various niobium based oxides materials (Nb2O5, TiNb2O7, LiNb3O8, etc.) are reviewed. The effects on lithium ion transfer and storage performance originate from component, particle morphology and preparation technology are discussed. Meanwhile, the influencing mechanism is also summarized. In addition, the generality in electrochemical lithium insertion and extraction behavior of niobium based oxides materials, the differences and similarities compared with Li4Ti5O12 are summarized the tendency and prospect of them as anode materials for high power lithium ion batteries in the end are also discussed.

At present, carbonaceous materials are extensively adopted as an anode for commercial lithium-ion batteries. Zero-strain lithium titanate is generally considered as a more safe and long-life span anode compared with carbonaceous materials, and it will find specific applications in various fields such as hybrid electric vehicles, wind-light-electricity grids, and smart grids. However, the lithium-ion batteries using the lithium titanate as anode will easily swell during the charge-discharge cycle and storage, thus resulting in shell distortion, gas evolution, performance deterioration, and so on. This greatly prevents the practical application of lithium titanate.In this paper, the industrial developments of the four kinds of lithium-ion batteries using the lithium titanate anode are reviewed, and the associated cathode materials are Li (Nix Coy Mn1-x-y) O2, LiMn2O4, LiFePO4, and LiCoO2, respectively. The latest research progress of the gas evolution mechanism is summarized from the perspectives of the interfacial characteristics, the water content, the electrolyte reductive decomposition, the negative electrode potential, and the impurities. At the same time, combined with the author's research work, the improving measures are put forward from the viewpoints of material, process, and application. Finally, the key issues and prospects of gassing are also commented.
