Improving electrochemical performances of Lithium-rich oxide by cooperatively doping Cr and coating Li3PO4 as cathode material for Lithium-ion batteries

Investigating dry room compatibility of sulfide solid-state electrolytes for scalable manufacturing

“…11 The P-O signal can be observed at 133.6 eV and 133.8 eV in the air-HT and water-HT samples, indicating the formation of Li 3 PO 4 . 34 The larger PS 4 3À peak area in air-HT than that of water-HT implies a larger degree of LPSCl recovery in air-HT sample. These are consistent with the previous XRD results.…”

K-doped Li2ZnTi3O8/C as an efficient anode material with high performance for Li-ion batteries

“…34,35 This difference was perhaps associated with a wider tunnel for Li 1.9 K 0.1 ZnTi 3 O 8 /C, a feature apt to increase the speed of Li + transport and further improve the electrochemical properties of the resulting electrode material. 36 Fig. 1(B) shows the XRD patterns of Li 1.9 K 0.1 ZnTi 3 O 8 /C before and after 100 cycles.…”

“…Therefore, Li 1.9 K 0.1 ZnTi 3 O 8 /C was indicated to demonstrate a better capacity retention and cycling performance than Li 2 ZnTi 3 O 8 /C, which could be attributed to the low-dose K + doping enlarging the Li + transport tunnels, and hence increasing the rates of Li + transport and electron transport. 36 …”

Cr-Doped Li2ZnTi3O8 as a High Performance Anode Material for Lithium-Ion Batteries

“…All electrochemical performances were tested in the voltage range of 0.05-3.0V at room temperature. parameters increased following introduction of Cr 3+ into the Li 2 ZnTi 3 O 8 crystal structure due to the larger radius of Cr 3+ (0.062 nm) compared with that of Ti 4+ (0.061 nm) (Novikova et al, 2018), which promotes the transportation of lithium ions and further enhances the electrochemical performance (Tai et al, 2020).…”
