“…To meet such demand, researchers are focusing on alternative anode materials with high energy density and long cycle life [4][5][6]. Among the alternative conversion anode materials, tin based materials gathered huge attention due to their high theoretical capacity (Sn-992 mAh g −1 , SnO-875 mAh g −1 and SnO 2 -782 mAh g −1 ), low cost, earth abundance, and non-toxicity [5,[7][8][9]. Despite all these advantages, the commercial use of tin oxide-based anodes is facing challenges because of the poor cycle life of the anode.…”

Li-ion batteries with conversion type anode are attractive choice, for electric vehicles and portable electronic devices, because of their high theoretical capacity and cycle stability. On the contrary, enormous volume change during lithiation/delithiation and irreversible conversion reaction limits use of such anodes. To overcome these challenges, incorporating nano-sized SnOx on flexible carbonaceous matrix is an efficient approach. A facile and scalable fabrication of SnO nanodisc decorated on SnO2 quantum dots embedded carbon (SnOx@C) is reported in the present study. Detailed structural and morphological investigation confirms the successful synthesis of SnOx@C composite with 72.3 wt % SnOx loading. The CV profiles of the nanocomposite reveal a partial reversibility of conversion reaction for the active materials SnOx. Such partial reversible conversion enhances the overall capacity of the nanocomposite. It delivers a very high discharge capacity of 993 mAh g-1 at current density of 0.05 Ag-1 after 200 cycles; which is 2.6 times higher than that of commercial graphitic anode (372 mAh g-1) and very close to the calculated capacity of the SnOx@C composite. This unique nanocomposite remarkably improves Li storage performance in terms of reversible capacity, rate capability and cycling performance. It is established that such engineered anode can efficiently reduce the electrode pulverization and in turn make conversion reaction of tin partially reversible.

Ultrasensitive Detection for Lithium-Ion Battery Electrolyte Leakage by Rare-Earth Nd-Doped SnO₂ Nanofibers

The problems of lithium-ion battery (LIB) failure have attracted growing attention since flammable and explosive electrolyte leakage might lead to serious consequences. However, due to the redox-neutral and volatile nature of main electrolyte components, such as dimethyl carbonate (DMC), trace leakages are difficult to detect. Therefore, research on LIB electrolyte sensors is urgent and lacking. Herein, sensors based on rare-earth Nd-doped SnO 2 nanofibers are reported for detecting DMC vapor in LIB. The excellent sensitivity (distinct response to 20 ppb DMC), high response (∼38.13−50 ppm DMC), and superior selectivity and stability of 3%Nd-SnO 2 suggest that it should be a promising candidate for LIB safety monitors. Meanwhile, it also shows clear and rapid response during the LIB-leakage real-time detection experiment. The doping of Nd endows SnO 2 with more oxygen vacancy defects. In addition, the highly active Nd sites greatly enhanced the adsorption energy of DMC on SnO 2 . All of these features contribute to the improvement of DMCsensing performances.

“…Then, the pristine nanofibers were heated to 280 °C for 2 h in air with a heating rate of 2 °C/min and then oxidized at 500 °C for 2 h. Owing to the Kirkendall effect, the hollow SnO 2 nanotubes with an inside diameter of 200 ± 5 nm and a shell thickness of about 40 nm were obtained (Figures S1b and S2b). 44 The tubular structure is beneficial to shorten the ion transport path and alleviate the volume expansion caused by Li + insertion and extraction. 45 After that, the SnO 2 nanotubes were coated with a polydopamine (DA) thin layer (SnO 2 @PDA) (Figures S1c and S2c).…”

Tin is a good anode material for lithium storage because of its high theoretical capacity and good conductivity, but large volume changes during the charging/discharging process lead to poor rate performance and cycling stability. In this work, by assembling ZIF-67 nanosheets on SnO2@PDA nanotubes and following a calcination process, heterostructured Sn/CoSn x (x = 1, 2) alloy anchored N-doped porous carbon nanotubes with high lithium storage performance were rationally designed and successfully prepared (Sn/CoSn x @C). The Co incorporated in CoSn x intermetallic can buffer the internal stress, and combined with the porous structure, the large volume expansion can be effectively alleviated. Besides, coating the ultrafine Sn/CoSn x crystals within one-dimensional N-doped carbon can inhibit particle agglomeration, thus enhancing cyclic stability. Moreover, benefiting from the porous tubular structure that can shorten the mass/charge transport distance, the generated abundant heterointerfaces can promote reaction kinetics, achieving improved rate capacity. Therefore, the tubular structured Sn/CoSn x @C anode shows a high reversible specific capacity of 1713.2 mAh g–1 at a current density of 100 mA g–1, a high rate performance of 1394.1 mAh g–1 at 1.0 A g–1 and 1051.3 mAh g–1 at 5.0 A g–1, and an excellent cycling stability of 444.3 mAh g–1 at 5 A g–1 over 5000 cycles. These results demonstrate an effective strategy for developing high-performance metal alloy-based electrodes in the energy storage system.
