Facile preparation of Sn hollow nanospheres anodes for lithium-ion batteries by galvanic replacement

Sb porous hollow microspheres as advanced anode materials for sodium-ion batteries

“…36 Secondly, the interior void space and holes in the porous shells could accommodate the large volume change during cycling, resulting in high capacity retention. 35,[40][41][42] Thirdly, sodium could go through a surface path and channels in the porous shells, facilitating sodium diffusion and allowing better reaction kinetics and the thin shell thickness guarantees a short Na + diffusion distance, which plays a vital role in the rate performance.…”

“…Lots of previous reports have conrmed that some special morphology such as porous and hollow structures may improve the electrochemical performances of the corresponding electrode materials for both LIBs and SIBs. [35][36][37][38][39][40][41][42][43][44][45][46][47] Therefore, the design of metallic Sb with porous and hollow structures to improve its electrochemical performance for SIBs is reasonable and signicant. In this paper, the Sb porous hollow microspheres were rst prepared through a chemical reduction reaction by employing commercialized Zn powder as the template and they were also applied as an anode for SIBs with superior cycle stability and rate capacity for the rst time.…”

TEM in situ lithiation of tin nanoneedles for battery applications

“…Indeed, Sn forms intermetallic compounds with Li with many of the same ratios and structures as Si does, however, most processes used to create nanostructures are slow and resource intensive. This is particularly so for nanoparticles of Sn [33] or hollow Sn spheres [34]. The difficulty in using nanoparticles is that they must be supported [35], even during preparation when using template synthesis [36], which may negate the advantage of their small size unless they are effectively unconstrained.…”

Nonlinear Potential Scanning as a Novel Approach to Calculation of the Time Variable Galvanic Displacement Reaction Rate

“…A surface‐treatment process for depositing Zn on Al or Mg alloys parts by galvanic displacement reaction is used prior to application of functional coatings on this alloys [10] . Metal nanostructures fabricated via galvanic displacement are used in production of catalysts, [11–21] sensors, [8,9,22] lithium‐ion batteries [23] . Galvanic displacement allowing to obtain ultrathin layers is known as “surface limited redox displacement” [13,24–28] …”

“…[10] Metal nanostructures fabricated via galvanic displacement are used in production of catalysts, [11][12][13][14][15][16][17][18][19][20][21] sensors, [8,9,22] lithium-ion batteries. [23] Galvanic displacement allowing to obtain ultrathin layers is known as "surface limited redox displacement". [13,[24][25][26][27][28] Along with all these applications, galvanic displacement reaction can lead to undesired processes.…”
