“…The OPC is also expected to be a promising NIB anode material because its enlarged interlayer spacings facilitate Na‐ion insertion/extraction, with a large number of mesopores that can serve as Na reservoirs and oxygen doping that provides more active sites for Na storage . Figure a shows the CV scans of the OPC electrode between 0 and 2.8 V (vs. Na/Na + ).…”

Sodium carboxymethylcellulose (CMC), which contains large amounts of carboxymethyl and hydroxy groups, has been used as an oxygen‐containing carbon precursor to prepare oxygen‐rich porous carbon (OPC) in a silica‐template process. CMC can be mixed homogeneously with the silica template because of its excellent water solubility and viscosity, which is one of the key reasons for the successful preparation of OPC. The obtained OPC possesses some micropores, many mesopores with different sizes, a large specific surface area of 1792.6 m2 g−1, and a high oxygen content of 8.63 wt %, and exhibits superb dual functionality as anodes for lithium‐ion and sodium‐ion batteries.

“…Gel polymerization route followed by carbonization in the presence of Sb precursors have been used to obtain well-dispersed nanometric Sb particles embedded into micrometer size amorphous carbon particles. [217] Around 428 mA h g −1 , calculated per gram of Sb, was achieved at a current density of 100 mA g −1 , with 93% of the capacity maintained after 500 cycles. Stable specific charge of 400 mA h g −1 at a charge rate of 500 mA g −1 and excellent rate performance (138 mA h g −1 @32 A g −1 ) were observed.…”

Once lithium-ion battery (LIB) technology has reached a maturity level enough to be the battery of choice for consumer electronics and power tools, it will be very well positioned to take over transport applications while displacing, for instance, NiCd and Ni-MH technologies. However, a major challenge is waiting for us in the near term: large scale and low cost stationary energy storage. This will be crucial for boosting the efficiency, adaptability, and reliability of the next-generation power grid. The use of stationary energy storage systems coupled to the The urgent need for optimizing the available energy through smart grids and efficient large-scale energy storage systems is pushing the construction and deployment of Li-ion batteries in the MW range which, in the long term, are expected to hit the GW dimension while demanding over 1000 ton of positive active material per system. This amount of Li-based material is equivalent to almost 1% of current Li consumption and can strongly influence the evolution of the lithium supply and cost. Given this uncertainty, it becomes mandatory to develop an energy storage technology that depends on almost infinite and widespread resources: Na-ion batteries are the best technology for large-scale applications. With small working cells in the market that cannot compete in cost ($/W h) with commercial Li-ion batteries, the consolidation of Na-ion batteries mainly depends on increasing their energy density and stability, the negative electrodes being at the heart of these two requirements. Promising Na-based negative electrodes for large-scale battery applications are reviewed, along with the study of the solid electrolyte interphase formed in the anode surface, which is at the origin of most of the stability problems.

“…They achieved a high charge capacity of 543 mAh g −1 with a capacity retention of 87.7% after 200 cycles at a current density of 0.1 A g −1 , and reversible capacity of 258 mAh g −1 can be retained even at 10 A g −1 . Comparatively, S and N codoped macroporous carbon contained Sb provides excellent performance in terms of tolerate volume expansion . Alternatively, the ionic liquid derived N‐doped carbon network has inspiring attention for SIBs due to the accommodation of large volume enlargement, superior electronic conductivity, and chemical bonding strategy …”

In the scenario of renewable clean energy gradually replacing fossil energy, grid‐scale energy storage systems are urgently necessary, where Na‐ion batteries (SIBs) could supply crucial support, due to abundant Na raw materials and a similar electrochemical mechanism to Li‐ion batteries. The limited energy density is one of the major challenges hindering the commercialization of SIBs. Alloy‐type anodes with high theoretical capacities provide good opportunities to address this issue. However, these anodes suffer from the large volume expansion and inferior conductivity, which induce rapid capacity fading, poor rate properties, and safety issues. Carbon‐based alloy‐type composites (CAC) have been extensively applied in the effective construction of anodes that improved electrochemical performance, as the carbon component could alleviate the volume change and increase the conductivity. Here, state‐of‐the‐art CAC anode materials applied in SIBs are summarized, including their design principle, characterization, and electrochemical performance. The corresponding alloying mechanism along with its advantages and disadvantages is briefly presented. The crucial roles and working mechanism of the carbon matrix in CAC anodes are discussed in depth. Lastly, the existing challenges and the perspectives are proposed. Such an understanding critically paves the way for tailoring and designing suitable alloy‐type anodes toward practical applications.
