A robust strategy for engineering Li4Ti5O12 hollow micro-cube as superior rate anode for lithium ion batteries

Dual-Modified Li4Ti5O12 Anode by Copper Decoration and Carbon Coating to Boost Lithium Storage

“…The peak at approximately 0.7 V in the initial lithiation process results from the generation of an SEI film. The cathodic peak in the first CV cycle is at about 1.25 V, which is slightly lower than those in the subsequent cycles, implying the surface structure reconstruction of LTO due to interfacial reactions. − Subsequently, the cathodic peak shifts to 1.5 V, and the anodic peak remains unchanged at 1.7 V, which is the characteristic lithiation behavior of LTO accompanied by the structural transition between spinel and ordered rock-salt. , The broad reversible peaks between 0.6 and 0.02 V correspond to the transition between the ordered rock-salt structure and disordered quasi-rock-salt structure, resulting in extra capacity . Apparently, the CV curves of LTO@C-Cu almost overlap except for the initial cycle.…”

Hybrid nanotubes constructed by confining Ti0.95Nb0.95O4 quantum dots in porous bamboo-like CNTs: superior anode materials for boosting lithium storage

“…40 It is worth mentioning that the electrochemical performance of the TN electrode was higher than that of the Li 4 Ti 5 O 12 and Ti–Nb–O based nanocomposites reported in the open literature (Table 2). 9,10,32,39–47…”

“…40 It is worth mentioning that the electrochemical performance of the TN electrode was higher than that of the Li 4 Ti 5 O 12 and Ti-Nb-O based nanocomposites reported in the open literature (Table 2). 9,10,32,[39][40][41][42][43][44][45][46][47] Moreover, the rate performance of TN was tested under the current densities from 0.5 to 8.0 A g −1 . When the current density is restored to the small current of 0.5 A g −1 , the capacity has almost no change, showing a good rate perform-ance (Fig.…”

“…Figure 3a shows the schematics diagram of Li4Ti5O12 with various nano/microstructures, including 0D, 1D, 2D and 3D [80] . The morphology control of Li4Ti5O12 can be designed to reduce the diffusion distance of Li + [91,92] . In addition, the nanostructure increases the surface area that can be used to reduce interfacial charge transfer, thus substantially improving the electrochemical activity.…”
