“…Some regular structure was found and its lattice spacing is corresponded to the (101) plane of Sn . Since the melting point of pure Sn is 232 °C and the electrode precursor was treated at 320 °C, indicating that some Sn was melted and seeped into carbon substrate . The Energy Disperse Spectroscopy (EDS) element mapping profile of the integrated SnO x /carbon electrode indicates that the SnO x particles were distributed evenly in the carbon (Figure c, d, e, f).…”

Tin (Sn) has been considered as a promising anode material for sodium ion battery due to its high specific capacity. However, its poor cycling stability and rate performance hinders the real application. Inspired by the structure of reinforced concrete and tunnel, an integrated SnOx/carbon composite anode was designed for high performance sodium ion batteries. In this structure, the SnOx nanoparticles were embedded in the amorphous carbon with interconnected pores derived from carbonization of the polyacrylonitrile (PAN) and starch, where the amorphous carbon can buffer the bulk expansion of SnOx to maintain structural stability and the interconnected pores can store the electrolyte to promote the sodium ion transportation for high rate reaction of the SnOx particles with sodium ion. The reduced graphene oxide as robust framework similar with rebar is inserted into the amorphous carbon/SnOx composite to enhance the stability and conductivity of composite. The starch as pore‐creating additive is decomposed during high‐heat treatment to form interconnected tunnel‐like pores in SnOx/carbon composite for electrolyte storage and high efficient sodium ion transportation. As a result, the as‐prepared integrated SnOx/carbon composite anode shows outstanding rate and cycling performance. Constructing the interconnected pore in SnOx/carbon composite using starch can greatly improve its charge specific capacity and rate performance.

“…We nd a slight increase in the thickness of the SnO x layer aer heat treatment (135 ± 3 nm), which is likely due to the volume expansion of the SnO x upon heat treatment. 28,29 The annealing temperature was chosen to avoid changes in the contact angles of H 2 O on the annealed GDL surfaces to ensure no structural changes on the GDL during heat treatment (Fig. S5 †).…”

“…A direct heating in furnace to provide precise temperature control, has been used to study the reflow performance of NS [25], however, in situ visual observation is not available. In situ TEM equipped with a heating holder can precisely control the temperature exerted on the nanomaterials combined with the overall system stability to image, therefore providing an in situ dynamic observation of the NS morphological evolution during heating [26][27][28]. Using this method, Yin et al have studied the length-dependent melting behavior of Sn nanowires, indicating that the melting induced their morphological evolution to change with the length/width aspect ratio [27].…”

Nanosoldering can bond various nanomaterials together or connect them with electrodes to form electrical contacts, thus assembling these nanomaterials into functional nanodevices; it is believed to be a promising interconnection technique due to its flexibility, controllability and crucial advantage of avoiding detrimental effects on the nano-objects. In this technique, molten solder as a filler material is introduced between the objects to be joined to form a reliable bond, in which the nanosolder reflow melting is a crucial prerequisite for successful nanosoldering. This work focuses on studying the melting characteristics of one-dimensional 97Sn3Cu nanosolder with low-cost, prominent electrical property and high mechanical reliability, aiming to promote its applications in nanosoldering. The reflow melting of an individual nanosolder has been dynamically observed by in-situ heating holder in transmission electron microscopy, where the obtained reflow temperature (530 °C) is much higher than its melting temperature (220.4 °C) because of the external oxide layer confinement. Furthermore, the size-dependent melting temperature of nanosolders with various diameters (20-300 nm) has been investigated by both differential scanning calorimetry and theoretical calculation, revealing that the melting temperature decreases as the diameter goes down, especially for the nanosolders in the sub-80 nm range, where the value decreases significantly. The experimental results are in good agreement with the theoretical predictions. These results pointed out here can be readily extended to other nanosolders.
