Co–Sn Nanocrystalline Solid Solutions as Anode Materials in Lithium‐Ion Batteries with High Pseudocapacitive Contribution

“…One main approach is to alloy the active phase, Sn, with a second element that can buffer the volume changes . In this direction, Sn‐based alloys with Ni, Co, Fe, Cu, and Sb have demonstrated superior cycling performance than bare Sn anodes. Among the different Sn‐based alloys tested, Co–Sn electrodes have shown particularly promising performances as anode materials for LIBs .…”

These nanoparticles were used as anode materials for Liion batteries.…”

In-Depth Analysis of the Conversion Mechanism of TiSnSb vs Li by Operando Triple-Edge X-ray Absorption Spectroscopy: a Chemometric Approach

“…1 However, fast capacity decay and short cycle life are still major drawbacks of these materials. 2 In spite of these difficulties several several promising conversion-type electrode materials have been presented and studied in the last years, based on either oxides 2 or 2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 p-group semi-metals such as tin [3][4][5] or antimony.

Structurally Ordered Intermetallic Cobalt Stannide Nanocrystals for High‐Performance Electrocatalytic Overall Water‐Splitting

“…Intermetallic compounds containing non-noble metals (main group and transition metals) were also shown to be potential candidates for application in data storage,m agnetic materials,e lectronics,a nd sensors to electrodes in rechargeable batteries. [3] However,t he geometric and electronic influence of such materials for the energy conversion and storage applications are still scarcely investigated.As acentral part for asustainable realization of renewable energy conversion, the development of inexpensive materials for technologies capable of electrochemical water-splitting into hydrogen and oxygen in an economically viable way is highly desired. [4] Currently,n oble-metal-based materials (Pt, RuO 2, and IrO 2 )have been considered as the state-of-the-art electrocatalysts for HER and OER;however,relatively high costs and scarcity of the materials greatly stint their widespread industrial applications.…”
