“…This result indicates that the aluminum compounds insert into the layered SnS materials, corresponding to higher aluminum concentration after discharging in Figure S5 (Supporting Information). [20,24] An unknown peak around 161.5 eV was found after charging, which is similar to the result using SnS 2 as the active material in AIBs. This variation of binding energy is assigned to the decomposition of aluminum compounds after charging.…”

“…On the other side, the XPS spectra of sulfur present a similar shift in the pristine, discharged, and charged states. [7,20,24,26,27] It is noted that this is the first time to find the variations of metallic and sulfur valence state in one AIBs system. [20] Similarly, after charging, the spectra of sulfur recovered to the pristine state with a higher binding energy increasing, revealing that a reversible reaction increases the valence state of sulfur.…”

Additionally, Al metal electrode is stable in open air under ambient condition, which is easier for manufacturing as compared to Li metal. Therefore, AIBs have been considered as a promising candidate for largescale energy storage in the future.However, the research progress in AIBs has been severely limited by developing new electrode and electrolyte. A key challenge is the sluggish Al 3+ ion diffusion in the host materials during electrochemical charge/discharge processes. Monovalent ions, such as Li + and Na + , could be easily inserted into and extracted from the host materials with a simultaneous charge transfer. [9] Owing to the three-electron transfer process in the charge/discharge reactions, the strong bonding between Al 3+ and the host materials would lead to slow diffusion kinetics in the host structures. In recent decades, aqueous electrolytes have been employed in AIBs. However, they deliver low discharge voltages and poor cell efficiencies. [10] Liu et al. developed copper hexacyanoferrate nanoparticles as cathode materials for AIBs in 0.5 m Al 2 (SO 4 ) 3 aqueous electrolyte, exhibiting low potential window of 0.2-1.2 V (vs SCE) and poor capacity retention of 54.9% after 1000 cycles. [9] Very recently, ionic liquid (IL) electrolyte was explored to replace aqueous electrolyte in AIBs. [8,11] For example, Wang et al. designed an AIB using pristine natural graphite flakes as an electrode with AlCl 3 /[EMIm]Cl as an electrolyte, achieving a high specific capacity of 110 mAh g −1 and Coulombic efficiency of 98%. [8] However, the obtained capacity is still far below the theoretical capacity. Therefore, it is urgent to develop new electrode materials with high specific capacity and good cyclability.Tin sulfides have attracted great attention as active materials for Li-ion and Na-ion batteries. [12] Especially, tin monosulfide (SnS, also called herzenbergite) is an important mineral on earth, which is chemically stable in the presence of water and oxygen. In addition, SnS is a typical layered material with a large interlayer spacing of 0.43 nm, which is available for the intercalation of alkali metal ions and compensation of the volume expansion during the charge/discharge process. [13] The layers of SnS are coupled by weak van der Waals forces, which are beneficial for reversible alkali metal ions storage. [14] Moreover, SnS presents excellent electric conductivities of 0.193 S and 0.063 S cm −1 in parallel and perpendicular to the basal plane, respectively. [15] Conventionally, carbonaceous materials and organic binders are widely employed in the fabrication of powder materialbased battery electrodes, which have low volumetric capacities and cannot meet the requirement for flexible energy storage.High-performance flexible batteries are promising energy storage devices for portable and wearable electronics. Currently, the major obstacle to develop flexible batteries is the shortage of flexible electrodes with excellent electrochemical performance. Another challenge is the limited progress in the flexible ...

A versatile electrode fabrication strategy based on electrospinning combined with airbrush–spraying (ECAS) is developed for the preparation of composite paper electrodes. The LiFePO4 paper electrodes (ca. 13 mg cm−2) display good cycling stability with a capacity decay of only 15 % over 300 cycles at 1 C for lithium‐ion batteries. It is also demonstrated that the ECAS technique can obtain ultrahigh areal capacities of 12.3 mAh cm−2 using electrodes with an extra‐high areal loading of LiFePO4 paper (>75 mg cm−2). A full cell is constructed with ECAS LiFePO4 paper as the cathode and ECAS Li4Ti5O12 paper as the anode.

Corrosion and surface icing severely shorten the service life of aluminum and its alloys. Herein, we synthesized wrinkled and porous, hollow, tubular SiO2 on an Al alloy, followed by fluorination with (Heptadecafluoro‐1,1,2,2‐tetradecyl) trimethoxysilane (FAS) and then infusing Krytox 100 for obtaining novel slippery liquid‐infused porous surfaces (SLIPSs). The unique structure greatly reduced the loss of lubricant due to the volatilization or subcooled condensation and thus effectively extended the life of the SLIPS. The corrosion resistance of as‐prepared SLIPS was five orders of magnitude higher than that of the bare Al alloy and did not change significantly after immersion in an NaCl solution for 93 days. The ice‐adhesion strength remained at approximately 18 kPa for the whole duration of the icing/deicing cycles. The samples exhibited a low contact angle hysteresis and superior self‐cleaning properties. In addition, we also revealed the differences in self‐cleaning and anti‐icing macroscopic phenomena of superhydrophobic surfaces (SHS) and SLIPS.
