“…Meanwhile, due to the high energy density, long lifespan and environmental friendliness, LIBs have been highly developed over the past decades and widely used in our daily life including portable electronics, electrical transportation, and even grid energy storage [5][6][7]. However, the current most mature LIBs cannot ever meet the ever-increasing demands [8][9]. Thus, a lot of new electrode materials with different storage mechanisms have been explored to improve the battery performance and reduce the cost [10][11][12][13].…”

Silicon-based material is one of the most promising substitutes of widely used graphite anodes for the next generation Li-ion batteries due to its high theoretical capacity, low working potential, environmental friendliness, and abundant natural resource. However, the huge volume expansion and serious interfacial side reactions during lithiation and delithiation progresses of the silicon anode are the key issues which impede their further practical applications. Rational designs of silicon nanostructures are effective ways to address these problems. In this progress report, we firstly highlight the fundamental scientific problems, and then focus on recent progresses in design, preparation, in-situ characterization methods and failure mechanism of nanostructured silicon anode for high capacity lithium battery. We also summarize the key lessons from the successes so far and offer perspectives and future challenges to promote the applications of silicon anode in practical lithium batteries.

“…Although LiCoO 2 is one of the earliest successfully commercialized cathode materials, with a low energy density, high cost and toxicity, it is not suitable to be applied as a power battery material (Lu et al, 2019;Xian et al, 2020;Cheng et al 2020). By substituting cobalt (Co) with nickel (Ni), LiNiO 2 has a similar layered crystal structure to LiCoO 2 .…”

Ni-rich layered transition-metal oxides with high specific capacity and energy density are regarded as one of the most promising cathode materials for next generation lithium-ion batteries. However, the notorious surface impurities and high air sensitivity of Ni-rich layered oxides remain great challenges for its large-scale application. In this respect, surface impurities are mainly derived from excessive Li addition to reduce the Li/Ni mixing degree and to compensate for the Li volatilization during sintering. Owing to the high sensitivity to moisture and CO2 in ambient air, the Ni-rich layered oxides are prone to form residual lithium compounds (e.g. LiOH and Li2CO3) on the surface, subsequently engendering the detrimental subsurface phase transformation. Consequently, Ni-rich layered oxides often have inferior storage and processing performance. More seriously, the residual lithium compounds increase the cell polarization, as well as aggravate battery swelling during long-term cycling. This review focuses on the origin and evolution of residual lithium compounds. Moreover, the negative effects of residual lithium compounds on storage performance, processing performance and electrochemical performance are discussed in detail. Finally, the feasible solutions and future prospects on how to reduce or even eliminate residual lithium compounds are proposed.

“…The increasing energy demand for power portable electronics and electric vehicles has made Li-ion batteries (LIBs) become a focus attention from an environmental point of view. [1][2][3][4][5] Compared to traditional metal oxide cathodes, organic and polymer materials as the electrode materials have displayed many advanced merits, such as structurally tunable, environmentally benign and elementally abundant, which makes it potential candidates for next generation electrode material applied in the electrochemical energy storage field. [6][7][8] The relative studies on the organic and polymer as the electrode materials mainly focus on conductive polymers, [9,10] carbonylbased materials, [11][12][13] nitroxide radical polymers, [14][15][16] and organosulfur functionalized polymers, [17][18][19] et al, which have shown exceptional performances as cathode of LIBs.…”

Organic and polymeric materials are excellent candidates for next generation advanced electrode materials. Therein, 2,6-Bis (4-(diphenylamino)phenyl)-9,10-anthracenedione (BDAPA) functional monomer was synthesized through Suzuki coupling reaction, and a novel anthraquinone-containing poly(triphemylamine) polymer (PBDAPA) was then prepared by the simple oxidative polymerization. The obtained novel functional polymer presented a unique urchin-like morphology with outgrowth of hollow tubular spiny, which possesses the improved specific surface area of~129.6 m 2 g À 1 and the small average mesopore diameter of 1.78 nm. As cathode material, the obtained PBDAPA compared to polytriphenylamine (PTPA), demonstrated two obvious discharge plateaus, corresponding to the double charge-discharge characteristics from p-type triphenylamine and n-type anthraquinone segments in the polymer, respectively. Also, PBDAPA exhibited an improved specific capacity of 132.7 mAh g À 1 and an enhanced rate capability with the discharge specific capacities of 140.6, 124.3, 107.5 and 97.1 mAh g À 1 at the discharge rates of 20, 50, 100 and 200 mA g À 1 , respectively. The introduction of anthraquinone unit in polytriphenylamine as well as the resulted open pore morphology for PBDAPA was responsible to the improved electrochemical performances, which makes it a potential strategy for the design and preparation of high performance organic lithium-ion batteries.
