Sphere-like SnO2/TiO2 composites as high-performance anodes for lithium ion batteries

Tin and Tin Compound Materials as Anodes in Lithium-Ion and Sodium-Ion Batteries: A Review

“…Tin oxide materials were first discovered and applied in LIBs with a high specific capacity by Idato et al from Fuji Photo Film in 1997 (Idota et al, 1997). From then on, SnO 2 -based anodes in LIBs have drawn considerable attention because of their high theoretical capacity, resource availability, environmental benignity, and low operating potentials (0.3 and 0.5 V vs. Li + /Li in charge and discharge processes; Li R. et al, 2019). The chemical reactions of SnO 2 with lithium electrodes involve the following two steps (Courtney and Dahn, 1997;Chen and Lou, 2013; FIGURE 1 | Schematic illustration (A) and SEM image (B) of tin nanoplates encapsulated in foam like graphene backboned carbonaceous carbon matrix (F-G/Sn@C), cycling performance (C) of F-G/Sn@C at 400 mA/g from 0.01 to 2.00 V.

Review of Modified Nickel-Cobalt Lithium Aluminate Cathode Materials for Lithium-Ion Batteries

“…After 400 cycles at 1.0 C, the capacity decreases from 123.7 to 86.7 mAh g -1 with a capacity retention of 70.1%, in which excessive Li is believed to reduce the cationic mixing and SnO 2 modification is deemed to restrict the undesirable side reaction between active materials and electrolytes [50]. Liu et al [51] have synthesized a multifunctional TiO 2 composite layer by the solid-state reaction to modify LiNi 0.8 Co 0.15 Al 0.05 O 2 materials to enhance the surface and structural stability confirmed by electron microscopy and XPS measurements, in which the substitution of Ti in the crystal structure realizes the synergistic effect of the composite layer and titanium doping by enhancing surface and 3 International Journal of Photoenergy structural stability via heterogeneous layer coating and bulk doping [52], and the electrochemical battery exhibits the highest initial capacities of 162.9 and 182.4 m Ah g -1 at 1.0 C and 0.1 C, and the discharge capacity retentions can reach 85.0% after 200 cycles at 1.0 C. Moreover, metal oxides doped with different metal elements can provide higher electronic conductivity. He et al [53] adopted electronically conductive antimony-doped tin oxide (ATO) to coat the NCA cathode material by a wet chemical process.…”

Confining FeS in graphitized carbon with void space for high and stable electrochemical storage performance of Na + and K +

“…When new SEI films are continuously formed during each cycle of the charge/discharge process, the electrolyte will be seriously consumed with inevitable capacity loss 12 . To solve these problems, many strategies have been explored in various transitional metal compound systems, such as morphology control 13‐16 constructing nanosized structures 17‐19 and compositing with passive materials 20‐24 . These works have greatly improved the electrochemical storage of Na‐ion in transitional metal compound electrode.…”
