“…[25,26] In addition to the XRD analysis, we further performed Raman spectroscopy analysis. More specifically, the cubic ZnS crystal structure can also be confirmed by the observation of the exposed (220) and (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) crystal planes along the zone axis of [001], as indicated by d-spacings of lattice fringes in Figure 1f. The morphology of the ZnSi 2 P 3 powder was further examined using field-emission scanning electron microscopy (FESEM; Figure S1, Supporting Information) and low-magnitude transmission electron microscopy (TEM, Figure 1e).…”

“…[1][2][3] However, the intrinsic low electronic and ionic conductivity as well as severe volume change dramatically degrade the obtainable capacity and cycling stability. [11,12] However, the electronic and ionic conductivities of these two phosphides are still low, resulting in unsatisfactory electrochemical performances. [3][4][5][6][7][8][9][10] Unfortunately, the complicated synthesis processes together with low yield greatly increase the cost of LIBs, although the well-designed nanostructure engineering did show better Li-storage performance in certain aspects (e.g., rate performance) compared to the micro-sized Si anodes.…”

Si-based anodes with a stiff diamond structure usually suffer from sluggish lithiation/delithiation reaction due to low Li-ion and electronic conductivity. Here, a novel ternary compound ZnSi 2 P 3 with a cationdisordered sphalerite structure, prepared by a facile mechanochemical method, is reported, demonstrating faster Li-ion and electron transport and greater tolerance to volume change during cycling than the existing Si-based anodes. A composite electrode consisting of ZnSi 2 P 3 and carbon achieves a high initial Coulombic efficiency (92%) and excellent rate capability (950 mAh g −1 at 10 A g −1 ) while maintaining superior cycling stability (1955 mAh g −1 after 500 cycles at 300 mA g −1 ), surpassing the performance of most Si-and P-based anodes ever reported. The remarkable electrochemical performance is attributed to the sphalerite structure that allows fast ion and electron transport and the reversible Li-storage mechanism involving intercalation and conversion reactions. Moreover, the cation-disordered sphalerite structure is flexible to ionic substitutions, allowing extension to a family of Zn(Cu)Si 2+x P 3 solid solution anodes (x = 0, 2, 5, 10) with large capacity, high initial Coulombic efficiency, and tunable working potentials, representing attractive anode candidates for next-generation, high-performance, and low-cost Li-ion batteries.

“…Such materials show high theoretical capacities and high capacities on first charging, but also rapid fading capacity retentions during cycling. [8][9][10][11][12] For a deeper insight into the charging and discharging mechanism of these anode materials the phases formed during lithiation have been investigated. In silicon anodes crystalline Li 15 Si 4 , which contains isolated Si anions, shows the maximum lithium content reached by electrochemical intercalation.…”

Dedicated to Professor Caroline Röhr on the Occasion of her 60 th Birthday.Binary lithium silicides and germanides as well as ternary lithium phosphidotetrelates have been intensively investigated with regard to their suitability as anode materials for all-solidstate-batteries. In this context we studied the ternary phase diagram Li/Tt/P on the phosphorus-poor side. The phosphide tetrelides Li 10.68(8) Si 5 P and Li 10.1(2) Ge 5 P are ternary compounds in the respective phase systems so far uniquely featuring discrete building blocks, which were previously found exclusively in binary alkali metal tetrelides and phosphides. Li 10.68(8) Si 5 P and Li 10.1(2) Ge 5 P contain aromatic Tt 5 pentagons with an environment of mostly ordered Li atoms and isolated P 3À anions with a coordination environment of predominantly disordered Li atoms. The five-membered ring subunits are stacked under formation of 1 ∞ [Li 6 Tt 5 ] chains (Tt = Si, Ge). chains. The compounds crystallize in the space group Pnma (63) (Z = 4) with cell parameters of a = 10.2434(3) Å, b = 4.2788(1) Å, c = 23.9767(3) Å for Li 10.68(8) Si 5 P and a = 10.3599(11) Å, b = 4.3072(2) Å, c = 24.267(2) Å for Li 10.1(2) Ge 5 P. The single crystal structure determination is supplemented by X-ray powder diffraction experiments and 7 Li, 29 Si and 31 P solid state MAS NMR spectroscopy. With respect to their electron count the compounds are placed between compounds comprising aromatic five-membered rings such as the electron-precise Zintl phase Li 8 MgSi 6 and the nonclassical Zintl phase Li 12 Si 7 having two extra electrons.

“…The 2D materials have attracted tremendous interest due to their exotic properties and great potential in practical applications,1,2 such as electronic device, energy storage, catalysis, sensing, and so on 3–5. More recently, the few‐layered and monolayered group IV‐V semiconductors have been fabricated and shown to possess excellent structural stability 6–12. Owing to their outstanding electrical and optical properties combined with suitable bandgaps (1.6–2.2 eV), the monolayered group IV‐V semiconductors are predicated to be promising candidates for electronic and optoelectronic applications 13–16.…”

Heterostructure of various 2D semiconductors have attracted extensive attention due to their tunable electronic properties and tremendous application potential. Using first‐principles calculations, the electronic properties of a GeP/graphene van der Waals heterostructure are studied and the physical mechanism of its properties modulated by strain and electric field are examined. The calculations reveal that not only the electronic properties of the GeP/Graphene heterostructure, but also the position of the graphene's Dirac cone, can be modulated by uniaxial strain. Interestingly, uniaxial strain can induce p‐type to n‐type Schottky contact transition and its band alignment allows photocatalytic water splitting. The band edges of the GeP relative to that of graphene are effectively modulated by transverse electric field. These findings provide comprehensive understanding of fundamental properties of the GeP/graphene heterostructure and its tunable electronic properties through strain engineering and electric fields, which will be helpful to the application of 2D GeP‐based nanodevices.
