“…However, as an electrode potential for practical applications, it must satisfy many other demands. 74 (1) Energy F I G U R E 4 Three typical mechanisms for the redox chemistry of organic electrodes density: the organic electrodes normally cannot present a wide voltage window (higher cathode voltage or lower anode voltage), while they can release a high capacity by overlithiation, such as 720 mAh/g for dimethyl trisulfide 75 and 902 mAh/g for cyclohexanehexone 76 as the cathode, 2000 mAh/g for 1,4,5,8-naphthalenetetracarboxylic dianhydride as the anode. 77 An energy density of 500-750 Wh/kg on the material level can be obtained.…”

Lithium ion battery has achieved great success in portable electronics and even recently electronic vehicles since its commercialization in 1990s. However, lithium-ion batteries are confronted with several issues in terms of the sustainable development such as the high price of raw materials and electronic products, the emerging safety accidents, etc. The recent progresses are herein emphasized on lithium batteries for energy storage to clearly understand the sustainable energy chemistry and emerging energy materials. The Perspective presents novel lithium-ion batteries developed with the aims of enhancing the electrochemical performance and sustainability of energy storage systems. First, revolutionary material chemistries, including novel low-cobalt cathode, organic electrode, and aqueous electrolyte, are discussed. Then, the characteristics of safety performance are analyzed and strategies to enhance safety are subsequently evaluated. Battery recycling is considered as the key factor for a sustainable society and related technologies are present as well. Finally, conclusion and outlook are drawn to shed lights on the further development of sustainable lithium-ion batteries.

“…However, the limited lithium resources as well as its uneven distribution will exacerbate prices to soar, thus giving a tremendous challenge to the large-scale applications of LIBs [3,4]. Alternatively, sodium ion batteries (SIBs) have received considerable attention in view of the relatively high abundance and uniform distribution of sodium resources as well as the similar electrochemical properties to lithium [5][6][7][8][9]. However, compared with Li + (0.69 Å), the larger ion radius of Na + (0.98 Å) could cause sluggish kinetics for conventional electrode materials, thus developing suitable electrode materials is highly desirable for SIBs [10][11][12][13][14][15].…”

“…The composite showed a loose porous structure formed by the agglomeration of small particles, and the uniform elemental mapping distribution of C, N and S indicated that PTT-O had been deposited on the carbon particles (Figure 3). It is assumed that the presence of carbon particle can help the dispersion of the newly formed polymer, making the polymers grow gradually on carbon powder [22]. An XPS survey (ESCALAB 250Xi, Thermo Fisher Scientific, Waltham, MA, USA) was conducted to study the elemental compositions and the valence states of PTT-O@C. Figure 5 shows the XPS spectroscopy of C, N and S elements for the composite.…”

As a class of redox active materials with some preferable properties, including rigid structure, insoluble characters, and large amounts of nitrogen atoms, covalent triazine frameworks (CTFs) have been frequently adopted as electrode materials in Lithium-ion batteries (LIBs). Herein, a triazine-based covalent organic framework employing 3,4-ethylenedioxythiophene (EDOT) as the bridging unit is synthesized by the presence of carbon powder through Stille coupling reaction. The carbon powder was added in an in-situ manner to overcome the low intrinsic conductivity of the polymer, which led to the formation of the polymer@C composite (PTT-O@C, PTT-O is a type of CTFs). The composite material is then employed in LIBs as anode material. The designed polymer shows a narrow band gap of 1.84 eV, proving the effectiveness of the nitrogen-enriched triazine unit in reducing the band gap of the resultant polymers. The CV results showed that the redox potential of the composite (vs. Li/Li+) is around 1.0 V, which makes it suitable to be used as the anode material in lithium-ion batteries. The composite material could exhibit the stable specific capacity of 645 mAh/g at 100 mA/g and 435 mAh/g at 500 mA/g, respectively, much higher than the pure carbon materials, indicating the good reversibility of the material. This work provides some additional information on electrochemical performance of the triazine and EDOT based CTFs, which is helpful for developing a deep understanding of the structure–performance correlations of the CTFs as anode materials.
