“…Obviously, at the beyond‐normal anode (7.1 mg cm −2 ) and cathode (14.4 mg cm −2 ) loadings, TC‐900// Na 3 V 2 (PO 4 ) 3 full‐cell also exhibits admirable areal energy/power density (3.2 and 74 mW cm −2 ), outperforming the majority of sodium‐ion batteries. [ 3,68–72 ] This indicates that the TC‐900 is a promising candidate for simultaneously realizing high areal power and energy storage toward high‐loading electrodes. Besides, the full‐cell with high mass loading also delivers a high capacity of 0.94 mAh cm −2 , excellent cycle stability (retention of 97.9%) after 100 cycles at 0.5 mA cm −2 , as well as an impressive areal energy density of 2.1 mWh cm –2 (Figure 5j).…”

Creating defects by heteroatom doping is commonly approved in respect of enhancing fast sodium‐ion storage of carbonaceous anodes ascribing to rich external defects, but the contribution of intrinsic carbon defects (e.g., vacancy) in improving rate‐capability has rarely been investigated. Here, a bio‐derived fibrous hard carbon with high‐reversible intrinsic defects is synthesized via metal‐assisted‐catalytic strategy. It is found that sp2‐hybridized carbon is united through catalytic‐tuning during thermal‐etching process along with the formation of low‐potential planar intrinsic carbon defects (vacancies and non‐hexagonal carbon rings) by sacrificing poor‐reversible carbon edges. Such integrated structures greatly improve the reversibility of defective sites and charge transfer kinetics, thus enhancing the slope sodium‐storage capacity of carbon below 1 V even at high current densities. Thus‐obtained fibrous carbon anodes enable boosted initial coulombic efficiency (≈90%) and ultrahigh‐rate capability in both half‐ (222.2 mAh g−1at 50 A g−1) and full‐cell (200 C, charged/discharged in ≈10 s). Interestingly, compared with meso‐/macroporous structures, such micropore‐dominated carbon fibers are more beneficial for fabricating high‐mass‐loading, crack‐free thick electrodes (>10 mg cm−2) with considerable areal‐capacity over 3.0 mAh cm−2. Paired with high‐loading Na3V2PO4 cathode (14.4 mg cm−2), full‐cell achieves admirable areal‐capacity over 1.4 mAh cm−2 and peak areal‐energy/power‐density of 3.2/74 mW cm−2.

“…This approach can mitigate the fatal volume effect of P while also serving as a SEI, enabling faster Na + transport rates. 167 Another solid-state sulfide electrolyte that has received significant attention is Na 3 SbS 4 (NSS), where Sb is a homologue of P. Zhiwen Wang et al pointed out that the compatibility of NSS with metallic sodium and sodium alloys is relatively poor. They attempted to mix different volumes of 1butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide (BMPTFSI) with NSS solutions and use a PVDF filtration membrane with submicrometer vertical channels to assist in the formation of a uniform coating.…”

At present, in response to the call of the green and renewable energy industry, electrical energy storage systems have been vigorously developed and supported. Electrochemical energy storage systems are mostly comprised of energy storage batteries, which have outstanding advantages such as high energy density and high energy conversion efficiency. Among them, secondary batteries like lithium batteries, sodium batteries, and lead-acid batteries have received wide attention in recent years. Lithium-ion batteries (LIBs) have existed for a long time. However, due to limited lithium resources worldwide, uneven distribution, and worrying safety issues, the development of LIBs has been gradually hindered. Meanwhile, sodium-ion batteries (SIBs), whose working principle is similar to that of LIBs, have been gradually emphasized by researchers due to the advantages of abundant resources and low cost. Moreover, all-solid-state sodium batteries (ASSBs), which have higher energy density, simpler structure, and higher stability and safety, are also under rapid development. Thus, SIBs and ASSBs are both expected to play important roles in green and renewable energy storage applications. This Review focuses mainly on the detailed introduction of the constituent materials of SIBs and ASSBs, analyzing the development of cathode and anode materials and the solid-state electrolytes (SSEs) in the past five years. The advantages and development direction of each SSE suitable for ASSBs are listed and remarked, and the nonactive materials such as separators and collectors are briefly mentioned. Finally, a reasonable assessment and prospects of the different materials and preparation methods are put forward.

Red phosphorus shows great promise as a high‐capacity anode material for Na batteries. Such electrodes that suffered from the fracturing impact of volume change during cycling can be effectively improved by 1D nanomaterials. However, the synthesis of 1D red phosphorus has rarely been studied and employed in sodium batteries. Here, a simple selenium‐induced method to generate fibrous nano red phosphorus is presented. It turns out that a small amount of selenium can not only induce high‐quality fibrous nano red phosphorus from commercial red phosphorus, but also benefit qualitatively to the sodium ionic conductivity. Interestingly, the selenium dopant can also manipulate the chemical state of phosphorus leading to valence tunability which is able to tolerate structural stability under the Na‐rich or Na‐poor condition. As a result, the optimal fibrous nano red phosphorus used as anode outperforms over the traditional red phosphorus ≈6 and ≈10 times in terms of rate performance and cycle stability, respectively. Furthermore, as employed for sodium metal anode protection, the symmetrical cell cycling maintains long stable at a low polarization voltage for over 1000 h. The full cell performs excellent cycling stability of 1500 cycles at 3 C and high‐rate performance up to 30 C.
