“…Additionally, a novel 3D binder‐free Li 3 V 2 (PO 4 ) 3 /C@N‐doped carbon fibers (Li 3 V 2 (PO 4 ) 3 /C@NCF) membrane electrode was developed by sintering of slurry (Li 3 V 2 (PO 4 ) 3 + glucose precursor)‐loaded filter paper . During thermal decomposition, the filter paper converted to N‐doped carbon fibers, which helped to form a 3D conductive network and also severed as the current collector.…”

To further increase the energy and power densities of lithium-ion batteries (LIBs), monoclinic Li V (PO ) attracts much attention. However, the intrinsic low electrical conductivity (2.4 × 10 S cm ) and sluggish kinetics become major drawbacks that keep Li V (PO ) away from meeting its full potential in high rate performance. Recently, significant breakthroughs in electrochemical performance (e.g., rate capability and cycling stability) have been achieved by utilizing advanced nanotechnologies. The nanostructured Li V (PO ) hybrid cathodes not only improve the electrical conductivity, but also provide high electrode/electrolyte contact interfaces, favorable electron and Li transport properties, and good accommodation of strain upon Li insertion/extraction. In this Review, light is shed on recent developments in the application of 0D (nanoparticles), 1D (nanowires and nanobelts), 2D (nanoplates and nanosheets), and 3D (nanospheres) Li V (PO ) for high-performance LIBs, especially highlighting their synthetic strategies and promising electrochemical properties. Finally, the future prospects of nanostructured Li V (PO ) cathodes are discussed.

“…Binder-free electrodes generally include the following types: firstly, one is in-situ fabricated with carbon-based materials, such as reduced graphene oxide (rGO) and carbon fiber. [28,29] Secondly, some binder-free electrodes still rely on substrates, including metal substrate, carbon nanotubes, carbon paper or other flexible materials. [30][31][32][33] Thirdly, templates, spark plasma sintering approach and powder extrusion moulding technology can be helpful to obtain the monolithic or ceramic electrodes without binders.…”

Achieving lithium‐ion batteries (LIBs) with ultrahigh rate at ambient‐temperature and excellent low temperature‐tolerant performances is still a tremendous challenge. In this paper, we design a binder‐free Li4Ti5O12 (LTO) electrode to achieve an excellent rate performance (∼75 % of its theoretical capacity at 200 C), in which, aligned CNT nanosheets were used to load LTO nanosheets decorated with silver nanocrystals. With combination of 1,3‐Dioxlane‐based electrolyte, there is nearly no initial voltage drop happen, and the capacity can be greater than 140 mAh g−1 (∼85 % of its specific capacity at room temperature) at −60 °C and 0.2 C. This study provides a practical guidance of the design of LIBs with outstanding rate performances and low temperature resistance.

“…Unfortunately, similar to Li 3 V 2 (PO 4 ) 3 [18][19][20], NVP has relatively low electronic conductivity that limits its electrochemical performance. These problems are overcome, by applying various strategies, such as controlling the particle size [21,22], coating the Na 3 V 2 (PO 4 ) 3 with conductive materials [23,24], or doping with metal ions [25].…”

This work focuses on the preparation of a 3D flexible Na 3 V 2 (PO 4 ) 3 /C fiber membrane, as selfstanding cathode for Na-ion batteries, via a facile and simple electrospinning method, is followed by a hot-pressing process. A series of heat treatment temperatures are studied in detail, it is found that the temperature of the thermal process is a key parameter for controlling the structural organization of the material, as well as the size and dispersion of Na 3 V 2 (PO 4 ) 3 nanoparticles on the carbon surface. Hence, Na 3 V 2 (PO 4 ) 3 nanoparticles, with a size of 40 nm and highly disperse on the carbon nanofibers, are obtained after calcination at 800°C. In addition, this sample (Na 3 V 2 (PO 4 ) 3 /C Nanofiber-800) exhibits the best electrochemical performances among all the samples. For instance, it displays a considerably high initial discharge capacity of 109, 84, 77, and 71 mA h g −1 at a current density of 0.1, 10, 20, and 30 C, respectively. Moreover, the Na 3 V 2 (PO 4 ) 3 /C Nanofiber-800 shows notable cycle stability with about 95.3% capacity retention of its initial capacity after 1000 cycles at 2 C, These high performances is attributed to the unique nanofiber structure and uniform distribution of Na 3 V 2 (PO 4 ) 3 nanoparticles in the highly conductive carbon matrix.
