“…For the in situ TEM observation of sodium ion battery electrode materials, it was reported that metallic Na was generated from Na compound by electron beam irradiation and directly reacted with the active material. [16] In order to check such a beaminduced effect, the contact of both electrodes without applying voltage also has been carried out. In this case, no Li intercalation was observed.…”

Portable power supplies, particularly lithium‐ion batteries (LIBs), will play a key role in achieving sustainable development goals, and electrode active materials for the next generation of LIBs with higher energy density and longer life time is highly demanded. For this, in situ visualization of Li behavior during the charge/discharge process is essential, and transmission electron microscopy (TEM) will be promising for this purpose. Here, a quite simple experimental setup consisting of a newly developed Li–C nanocomposite film sputter‐deposited onto Au nanoprotrusions at room temperature and graphene synthesized on a W probe at 500 °C for the in situ TEM observation of the battery reaction is proposed. The preservation of the metallic Li in the Li–C film that is transferred to TEM without using any transfer vessels under atmospheric conditions is confirmed by high resolution TEM before the in situ electrochemical process in TEM. After the one cycle of the in situ electrochemical process, the intercalation of Li ions into graphene (lithiation) is clearly observed. Thus, it is concluded that the metallic Li stored in the Li–C film works well as the anode active material in the electrochemical process for solid state LIBs, implying the developed in situ experimental system is promising.

“…In the last century, a number of electrolytes for Cu-Sb alloy electrodeposition have been proposed to produce bright, corrosion-resistant hard alloys [3][4][5][6]. Recently, Cu-Sb-based alloys have been developed and investigated as a promising anodic material for Li-ion and Na-ion batteries, which have demonstrated high safety and capacity, as well as low weight and cost [4,[7][8][9][10][11]. Moreover, Cu-Sb-S and Cu-Sb-Se ternary semiconductors are considered as a sustainable alternative for fabricating lightabsorbing thin-film materials for solar applications owing to lower cell cost and recyclability [12][13][14][15][16][17].…”

The electrodeposited antimony-copper coatings demonstrate a varying degree of chemical and structural heterogeneity that determines their corrosion behaviour in 0.5M sodium chloride. The electrochemical and corrosion properties of layers at open circuit potential were investigated by electrochemical impedance spectroscopy and optical surface observation. Corrosion polarisation tests revealed that anodic behaviour of Sb-Cu alloys is similar for the all tested samples and depends on the antimony chemical resistance. Under anodic polarisation up to about −0.03 V Ag/AgCl a multistep process of anodic oxide film transformation was registered. The observations by SEM revealed that at a higher anodic polarisation many submicron-sized pits are formed. The formation of microgalvanic corrosion cells results in preferential dissolution of the antimony phase at both OCP and anodic polarisation.

“…As depicted in Figure 5f, when scanned from low voltage to high voltage (relative to Na/Na + ), at 0.1 mV s −1 , the SCN anode displayed four well-defined peaks of oxidation at 0.21, 0.29, 0.54, and 0.64 V, responding to the formation of Na 15 Sn 4 , Na 9 Sn 4 , NaSn, and NaSn 5 , respectively. 9,45,46 Furthermore, a pronounced reduction peak near 0.04 V, corresponding to the form of the Na x Sn alloy, can be observed as the voltage decreased. In addition, CV at sweep rates from 0.1 to 0.8 mV s −1 was performed to further study the behavior of Na + storage from 0.01 to 1.0 V (Figure 5f).…”

Tin (Sn) anode is a prospective anode for high specific capacity sodium ion batteries (SIBs). Nevertheless, tin suffers from extensive volume expansion during the charge/ discharge, which results in huge internal resistance and rapid capacity decay in SIBs. Herein, a hierarchical buffer structure of Cu 6 Sn 5 and nitrogen-doped carbon coating matrix is designed via the Oswald ripening process, CuO and PDA coating, and thermal reduction to obtain the multi-yolk−shell Sn/Cu 6 Sn 5 @ N−C anode material (SCN). The hierarchical buffer structure of SCN can minimize mechanical stress, avoid agglomeration, and enhance fast Na + /e − transfer at the solid electrolyte interface (SEI), which endows the SCN anode with greatly reduced contact impedance and stable long cycle performance. Consequently, the SCN anode reveals an outstanding specific reversible capacity of 440.1 mA h g −1 after 1000 cycles at 1 A g −1 with an ultralow decay of 0.024% per cycle. Even at 10 C, the specific capacity is maintained up to 486.6 mA h g −1 having a capacity retention of 90.8%, indicating outstanding rate performance.
