“…[9,10] For example, graphite, a commercially successful LIBs anode, has poor Na-storage performance with a reversible capacity of 35 mAh g −1 due to difficult intercalation of larger Na + between the graphite interlayer as well as the graphite intercalation compound of Na is thermodynamically more unstable than those of other alkalis. [11] In this regard, various anode materials have been explored, such as carbonaceous materials, [12][13][14][15][16] alloy, [17][18][19] metal oxide/sulfide, [20,21] phosphorus, [22,23] and MXenes. [24][25][26][27][28][29][30] The carbonaceous materials are relatively promising due to their low cost, abundant resource, environmental friendliness, and nontoxicity.…”

Sodium-ion batteries (SIBs) are regarded as a kind of promising candidate for large-scale energy storage technology. The development of advanced carbon anodes with high Na-storage capacity and initial Coulombic efficiency (ICE) from low cost, resources abundant precursors is critical for SIBs. Here, a carbon microcrystalline hybridization route to synthesize hard carbons with extensive pseudo-graphitic regions from lignite coal with the assistance of sucrose is proposed. Employing the cross-linked interaction between sucrose and lignite coal to generate carbon-based hybrid microcrystalline states, the obtained hard carbons possess pseudo-graphitic dominant phases with large interlayer spaces that facilitate Na ion's storage and transportation, as well as fewer surface defects that guarantee high ICE. The LCS-73 with an optimum cross-link demonstrates the highest Na-storage capacity of 356 mAh g −1 and an ICE of 82.9%. The corresponding full-cell delivers a high energy density of 240 Wh kg −1 (based on the mass of anode and cathode materials) and excellent rate capability of 106 mAh g −1 at 10 C in addition to outstanding cycle performance with 80% retention over 500 cycles at 2 C. The proposed work offers an efficient route to develop high-performance, low-cost carbon-based anode materials with potential application for advanced SIBs.

Owing to the abundant resources of potassium resources, potassium ion batteries (PIBs) hold great potential in various energy storage devices. However, the poor lifespan of PIBs anodes limit their merchant applications. The exploitation of anode materials with high performance is one of the critical factors to the development of PIBs. Metallic Sn-, Sb-, and Bibased materials, show promising future thanks to their high theoretical capacities and safe working voltage. However, the rapid capacity decay caused by the large K + is still a pivotal challenge. In this review, recent progresses on alloying anodes were summarized. Schemes, such as ultra-small nanoparticles, hetero-element doping, and electrolyte optimization are effective strategies to improve their electrochemical properties. This review provides an outlook on the nanostructures and their synthesis methods for the alloying-type materials, and will stimulate their intensive study for practical application in the near future.

“…With the development of portable electronics, increasing demands for economical and large-scale energy storage devices have led to the extensive exploration of sodium ion batteries (SIBs) owing to the abundant and low cost Na resource . However, the larger ionic radius of Na + than Li + always results in more sluggish electrochemical reaction kinetics and lower Na-ion storage capacity, thereby leading to poor cycling stability and low volumetric energy density, which would severely hinder its further practical applications. , Thus, ideal electrode materials with high volumetric capacity and cyclability are urgently required for practical SIBs. , …”

High volumetric capacity and durability anode materials for sodium ion batteries have been urgently required for practical applications. Herein, we reported a Sn-pillared pyknotic graphene conductive network with high-level N-doping. This densely stacked block offers high volumetric Na-ion storage capacity, rapid electrochemical reaction kinetics, and robust structural stability during cycling owing to the high capacity component (metallic Sn ≈847 mAh g −1 ), high tap density (≈2.63 g cm −3 ), high conductivity (N doping ≈5 at. %), and strong spatially confined and pillared structure. Moreover, theoretical simulations have indicated that the charge accumulation around the N-doped region is more pronounced compared to the pristine one, and electrons accumulate around the N atom while loss occurs at the Na atom. These studies also suggest that it might possibly contribute to higher conductivity and stronger electrophilic reactivity, thereby resulting in enhanced Na-ion storage performance. As a result, the as-obtained electrode material exhibits competitive volumetric capacity (1462 mAh cm −3 at 0.1 A g −1 ), cycling performance (1207 mAh cm −3 after 100 cycles), and promising rate behavior simultaneously.
