Antimony and red phosphorus (RP) hybrid is harvested via a facile mechanical milling strategy. Simultaneously, graphene sheets are introduced to boost the electronic transmission and mitigate the agglomeration of particles. In contrast to pristine Sb and RP electrodes, Sb/P/C hybrid affords comparably promising electrochemical performances. As anodes for lithium-ion batteries, Sb/P/C electrode depicts a reversible capacity of 869 mAh g −1 under 200 mA g −1 after 50 cycles and an excellent rate stability such as 452 mAh g −1 at 3200 mA g −1 . When used for sodium-ion batteries, the hybrid also shows moderate capacities of 544.8 and 511 mAh g −1 at the current of 50 and 200 mA g −1 after 50 cycles, respectively. These excellent properties can be ascribed to the synergetic effect of decreased particle size of milled Sb/P/C, large contact area, adequate energy storage sites, and enhanced electrical conductivity.

Silicon is a strong competitor for the anode of the next generation of lithium-ion batteries, and ball-milled silicon has broad prospects as a low-cost method for preparing nano silicon. In order to match ball-milled silicon, it is imperative to develop better bonding agents with lower costs. Through adding amino silane coupling agent, the performance of ball-milling silicon anode is enhanced. This study explored the network structure formed by amino silane coupling agent with different chain lengths and polyacrylic acids. Herein, the crosslinked network prepared with 3-[2-(2-aminoethyl amino) ethyl amino] propyl-trimethoxysilane as coupling agent had the best performance, and the initial discharge capacity of the silicon anode prepared by this binder reached 3297.4 mAh·g −1 at a constant current density of 0.5A·g −1 , the initial Coulomb efficiency reached 92.25%. After 100 cycles, the discharge capacity of anode was still maintained at 2229.5 mAh·g −1 with excellent charge/discharge performance.

Li 7 P 3 S 11 (70Li 2 S·30P 2 S 5 ) sulfide is a promising electrolyte candidate for all-solid-state lithium batteries (ASSLBs) owing to its high ionic conducivity and wide electrochemical stability window. However, the sensitivity to moisture and the poor interfacial compatibility with electrodes limit the conventional application of Li 7 P 3 S 11 . Herein, we present a substitution strategy to produce a O-incorporated 70Li 2 S·(30-x)P 2 S 5 ·xP 2 O 5 (mol%) sulfide electrolyte to address above issues. The elaborately designed electrolyte is prepared via wet vibration ball milling technique with P 2 O 5 substitution content of 1, 3 and 5. As a result, the 70Li 2 S·27P 2 S 5 ·3P 2 O 5 electrolyte displays the highest ionic conductivity of 2.61× 10 −3 S cm −1 which outperforms than that of pristine Li 7 P 3 S 11 (ionic conductivity of 1.35 × 10 −3 S cm −1 ) and the assembled LiCoO 2 @LiNbO 3 /70Li 2 S·27P 2 S 5 ·3P 2 O 5 /Li-In ASSLB exhibits the superior capacity retention of 93.2% after 100 cycles at 0.5C. The reason for the developed electrochemical performance lies in the substitution of the non-bridging sulfur atom with bridging oxygen atom, from which the interaction between electrolyte and lithium ions is weakened, thereby the rapid transfer of lithium ions is facilitated. Furthermore, Raman and XRD results indicate that the adverse interfacial reactions are suppressed through P 2 O 5 substitution. This work suggests that P 2 O 5 substitution is an effective strategy for sulfide electrolyte toward high energy all-solid-state lithium batteries.

The poor interface between the active materials, solid electrolytes, and conductive additives in composite cathode materials is the key factor restricting the performance of the all-solid-state lithium-sulfur battery. Here, the composite cathode material was prepared through the method of one-step ball milling. The sulfide electrolyte Li 3 PS 4 (LPS) was formed on the surface of the active material Li 2 S while the conductive additives were incorporated, and the conductive ions and electronic network were constructed simultaneously. After adding an appropriate amount of carbon nanotubes (cnt), the composite cathode exhibited high specific capacity of 1145.2 mAh g −1 after 30 times of cycling at a current density of 0.2 mA cm −2 , and the battery with ultrahigh areal Li 2 S loading also displays high capacity of 962.6 mA g −1 . The composite cathode with high Li 2 S content (56.3%) was prepared, with excellent performance exhibited: the capacity is 741 mAh g −1 after 30 times of cycling at a current density of 0.2 mA cm −2 .
Without additional sulfide electrolyte, the composite cathode materials were prepared by one-step ball milling with lithium sulfide, phosphorus pentasulfide, acetylene black, and carbon nanotubes as raw materials.

Quaternary Cu 2 MnSnSe 4 alloys with low intrinsic thermal conductivity are identified as promising middle-temperature thermoelectric materials. However, zT is depressed by the poor electrical performance. To overcome this issue, here, a series of Cu 2.1 Mn 0.9 SnSe 4 samples are prepared by ball-milling method which appears as a time-saving technique and lattice strain variation is observed by changing the annealing time ( x = 0, 1, 2, 3, 4 days). The vacancy defects concentration of Cu, with lowest vacancy defects formation energy, is changed with the competition between compression and tension-strain state, consistent with the first principles calculations, which optimizes the carrier transport. As a result, about 4 times increment of the carrier mobility is found. Moreover, the lattice strain of several nanometers is observed with TEM analysis, which scatters phonon strongly. A lowest κ L value of 0.57 W m −1 K −1 at 673 K is obtained for x = 3 sample, which is close to the amorphous limit. The interactive effect of enhanced mobility and strong scattering of phonons, contributing to a record zT ∼ 0.48 at 673 K for x = 3 sample. Lattice strain engineering is an effective tactic to simultaneously optimize the electrical and thermal transport.

Potassium-ion batteries (PIBs) are becoming one of the promising alternative metal-ion battery systems to lithium-ion batteries due to the abundance and low cost of potassium . Among the anode materials for the metal-ion battery systems, phosphorus-based materials are attractive due to the low cost and their high theoretical-specific capacity. Herein, for the first time, we report the selenium -phosphorous-carbon (Se–P–C) amorphous composites prepared by the plasma-assisted ball milling method as the high-performance anode material for PIBs. In particular, when the amorphous Se–P composite anode with the molar ratio of 1:2 and the P-milling time of 30 h (Se–2P/C@30 h), the associated PIB delivers a high reversible capacity of 634 mA h g −1 at a current density of 0.05 A g −1 and excellent rate capability of 248.6 mA h g −1 at a current density of 1 A g −1 . Furthermore, the experimental characterization and analysis reveal the reaction mechanisms that K–P (K 2 P 3 ) and K–Se (KSe) phases are formed during the potassiation process. The present work provides a facile approach to achieve a promising anode material for K-ion batteries, and the preparation route can be viewed as a reference for the further development of phosphorous-based anodes with high capacity and long cycle life for PIBs.

In this study, alkali hydroxides (NaOH, LiOH, KOH) were attempted as new-type catalytic additives to improve the hydrogen storage properties of MgH 2 by ball milling . It is shown that the additives readily react with the MgH 2 to form perovskite-structured NaMgH 3 and KMgH 3 , but not the LiMgH 3 . Although the in-situ formed perovskite hydrides remain stable during hydriding/dehydriding cycles, both NaMgH 3 and KMgH 3 show predominant catalytic role on the hydriding and dehydriding of MgH 2 . In contrast, the LiOH modified MgH 2 presents much inferior sorption kinetics because of the absence of LiMgH 3 . The catalytic mechanism of perovskite hydrides can be explained by the high hydrogen mobility in the perovskite structure . This study shows that such cheap hydroxides could be used as efficient catalysts to improve the hydrogen storage properties of high-capacity metal hydrides and complex hydrides .

Ti 1.4 V 0.6 Ni + x LiAlH 4 ( x = 0.5, 1, 1.5, 2, 2.5, wt.%) composites were prepared by ball-milling, and the effects of LiAlH 4 content on structure and electrochemical properties of the composites were investigated systematically. The addition of LiAlH 4 to the Ti 1.4 V 0.6 Ni alloy significantly affected the morphology and size of the composite particles . The electrochemical cycling stability and rate dischargeability of the composite electrodes benefitted from adding some LiAlH 4 ( x = 1), which however deteriorated when the LiAlH 4 content increased further. The positive effect of LiAlH 4 on the electrochemical performance of the studied alloy was caused by suppression of the dissolution of active components of the Ti 1.4 V 0.6 Ni hydrogen storage alloy.

Nickel sulfides decorated reduced graphene oxide (rGO) has been produced by co-reducing Ni 2+ and graphene oxide (GO), and is subsequently ball milled with Mg nanoparticles (NPs) produced by hydrogen plasma metal reaction (HPMR). The nickel sulfides of about 800 nm completely in situ change to MgS, Mg 2 Ni and Ni multiple catalysts after first hydrogenation/dehydrogenation process at 673 K. The Mg-5wt%NiS/rGO nanocomposite shows the highest hydrogen desorption kinetics and capacity properties, and the catalytic effect order of the additives is NiS/rGO, NiS and rGO. At 573 K, the Mg-NiS/rGO nanocomposite can quickly desorb 3.7 wt% H 2 in 10 min and 4.5 wt% H 2 in 60 min. The apparent hydrogen absorption and desorption activation energies of the Mg-5wt%NiS/rGO nanocomposite are decreased to 44.47 and 63.02 kJ mol −1 , smaller than those of the Mg-5wt%rGO and Mg-5wt%NiS samples. The best hydrogen desorption properties of the Mg-5wt%NiS/rGO nanocomposite can be explained by the synergistic catalytic effects of the highly dispersed MgS, Mg 2 Ni and Ni catalysts on the rGO sheets, and the more nucleation sites between the catalysts, rGO sheets and Mg matrix.
