Electrochemical performance of pre-lithiated ZnMoO4 and r-GO@ZnMoO4 composite anode for lithium-ion battery application

Practical evaluation of prelithiation strategies for next‐generation lithium‐ion batteries

“…25 Recently, Singh et al directly integrated prelithiation and material synthesis to prepare prelithiated ZnMoO 4 , which showed better reversible capacity (~1000 mAh g −1 at 0.1 A g −1 ) and superior rate capability (~400 mAh g −1 at 2 A g −1 ). 26 A spinel-type LiMn 2 O 4 cathode can store extra irreversible Li + with the help of the Mn 4+ /Mn 3+ redox pair, thereby forming a Li-rich Li 1+x Mn 2 O 4 (0 < x < 1) phase. 27 The irreversible Li + in Li 1+x Mn 2 O 4 can be released during the first cycle, so prelithiation of the spinel LiMn 2 O 4 cathode is a feasible method to compensate for the anodic ICL in a full battery.…”

“…Also, Chen et al constructed a galvanic cell to prelithiate SnO 2 with metallic lithium as the lithium source 25 . Recently, Singh et al directly integrated prelithiation and material synthesis to prepare prelithiated ZnMoO 4 , which showed better reversible capacity (~1000 mAh g −1 at 0.1 A g −1 ) and superior rate capability (~400 mAh g −1 at 2 A g −1 ) 26 …”

Structural Transformation of Hydrated WO3 into SnWO4 via Sn Incorporation Enables a Superior Pseudocapacitor and Aqueous Zinc-Ion Battery

“…Among binary metal oxides, metal tungstate compounds MWO 4 (M = Cu, Ni, Zn, Mn, Sn, etc.) are the most favorable electrode materials as a result of two dissimilar metal cations offering multiple redox activities. − MWO 4 is highly employed for catalysts, sensors, biosensors, optical fibers, photocatalysis, energy storage, luminescent materials, etc. − However, there are very limited attempts made on SnWO 4 for lithium-ion batteries and the supercapacitor applications thus far. For the lithium-ion battery, orthorhombic α-SnWO 4 has demonstrated the specific capacity of 75 mAh g –1 after 100 cycles .…”
