“…Both spectra show a couple of strong vibrational bands at around 1680, 1425, and 1296 cm –1 , corresponding to the stretching of CO, bending of CO, and stretching of C–OH, respectively . The moderate peaks at 1605 and 756 cm –1 can be attributed to the stretching vibrations of aromatic CC and C–H, and the peak at 565 cm –1 belongs to the Fe–O vibration. − …”

Iron oxide (Fe 2 O 3 ) is emerging as a potential anode alternative for lithium-ion batteries (LIBs) due to the merits of high specific capacity, environmental friendliness, and costeffectiveness. However, trapped by unsatisfactory cycling stability and rate capability, further modification is needed for Fe 2 O 3 to achieve practical requirements. In this study, a Fe 2 O 3 -based composite anode (namely Fe 2 O 3 @HA-Fe-BPDC) with interlocked structure was designed and synthesized for pursuing enhanced electrochemical properties. Benefiting from the porous structure, abundant active sites, and good tolerance to volume expansion, the as-prepared electrode exhibits significantly boosted rate capability, excellent specific capacity, and satisfactory reversibility. Typically, the Fe 2 O 3 @HA-Fe-BPDC anode provided an excellent specific capacity of 708 mAh g −1 at 0.1 A g −1 and remained at a high level of 332 mAh g −1 at 1 A g −1 , delivering significantly improved rate performance than Fe 2 O 3 . Additionally, outstanding capacity retention (95.4%) was achieved at 1 A g −1 after 600 charge/discharge cycles. The strategy based on the facile coprecipitation for fabricating Fe 2 O 3 and MOF composite electrodes provides a feasible technique to develop a high-performance anode for LIBs.

“…Besides, P 1 of TKX-50(ss) (89.4 %) was significantly larger than that of TKX-50(r) (66.03 %) and the total mass loss of TKX-50(ss) was 96.58 %, suggesting that the decomposition of TKX-50 was more complete after spherification and refinement. The earlier reaction temperature and increased reaction rate were mainly due to the reduction in particle size [36].…”

Micro/nano energetic materials with regular morphologies exhibit high energy release efficiency, superior charge performance, and low mechanical sensitivity. Exploring dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate (TKX-50) with spherical microstructures and excellent comprehensive properties is of great significance for potential applications. In this work, a kind of superfine spherical TKX-50 was fabricated by spray drying method. The as-prepared TKX-50 had a narrow particle size distribution with d 50 = 3.14 μm, high sphericity of 0.944 with hollow structure and bulk density of 1.851 g/cm 3 . And its formation mechanism was proposed. The results of XRD and FT-IR demonstrated that spray drying would not change the crystal structure of TKX-50. TG-DSC results showed that the initial decomposition and the peak temperature of superfine spherical TKX-50 was about 10 °C lower than raw TKX-50, and the apparent activation energy was 4.584 kJ • mol À 1 lower than raw TKX-50, due to the dramatic change in morphology. TG-DSC-FTIR-MS provided a new understanding of decomposition process of TKX-50, and the results illustrated that the main gas products were N 2 , H 2 O, N 2 O, NH 3 , NO, NH 2 , CO 2 , and HCN. Superfine spherical TKX-50 underwent similar decomposition path as raw TKX-50 but stood out in its larger occupation of the first decomposition which meant a more complete decomposition and its faster rate of the whole decomposition process. More importantly, the impact sensitivity (H 50 ) increased from 50.1 cm to 70.8 cm, and the friction sensitivity (P) decreased from 24 % to 0 %, showing improved safety performance.
