Transition metal oxides as a cathode for indispensable Na-ion batteries

Abstract

Na+ ion intercalated layered metal oxides have tremendous applications as the cathode materials for SIBs owing to their superior electrochemical performance compared to other types of cathode materials.

Minireview on Layered Transition Metal Oxides Synthesis Using Coprecipitation for Sodium Ion Batteries Cathode Material: Advances and Perspectives

“…The cathode is the most critical component in SIBs which loses electrons during charging and gains them during discharging. 29 The electrochemical properties and life of the battery depend on the structure of the cathode material. 7 The cathode of a battery is usually prepared by the combination of active material (∼ 95%), conductive carbon (∼1%), binder (∼4%), and solvent.…”

Effect of Ti1−xFexO2 photoanodes on the performance of dye-sensitized solar cells utilizing natural betalain pigments extracted from Beta vulgaris (BV)

“…Previous studies suggested that transition metal doping alters the electronic dimensions, provides structural stability, and tunes the light absorption. [14][15][16][17] In most of the previously reported works on the BV dyebased DSSCs, generally photoanode structures were examined to investigate the device performance and stability. Although many nanostructured photoanodes were investigated it was impossible to significantly enhance the DSSC performance due to the insufficient charge collection efficiency, low photoscattering, and higher interfacial charge recombination.…”

Vertically aligned MoS2nanosheets on monodisperse MXene as electrolyte-philic cathodes for zinc ion batteries with enhanced capacity

“…), which are abundant in resources and low cost. 1,[6][7][8][9][10] Aqueous zinc ion batteries (ZIBs) are considered to be ideal candidates over lithium-ion batteries due to their low redox potential (−0.763 V vs. standard hydrogen electrode (SHE)), 6,[11][12][13] high theoretical specic capacity (820 mA h g −1 and 5855 mA h cm −3 ), 14,15 non-toxic properties 6 and abundant Zn resources. 7 A typical ZIB generally compose of Zn metal anode, electrolyte, and cathode electrode for accommodating Zn ions.…”
