Synchronous embedded growth of Mo₂C nanodisk arrays immobilized on porous carbon nanosheets for ultra-stable sodium storage

Abstract

Sodium ion capacitors (SICs) that combine the merits of both rechargeable batteries and supercapacitors have gained widespread recognition for their high energy density and extended cycle life as a new...

Isomers of terephthalate derivatives as anodes for sodium-ion batteries

“…According to previous reports, the kinetics of sodium ion transport can be evaluated by examining the correlation between the response current and the scan rate. 44–47 The ratio of log i /log v was calculated from the cathodic and anodic peaks of the P-TT and M-TT electrode (Fig. 6a and d).…”

1D MnSe@carbon nanofiber as a high-rate anode for sodium-ion batteries: electrochemical and ex situ mechanistic investigation of Na+ charge storage

“…12–14 However, they also have limited theoretical capacity. The conversion type anodes include metal sulfides (MnS, SnS), 15,16 metal selenides (SnSe, FeSe), metal phosphates (SnP), and metal oxides (Fe 2 O 3 ), which have high theoretical capacity (300–900 mA h g −1 ). 17,18 For the conversion anodes, the new compound formation and involvement of multi electrons during sodiation lead to high theoretical capacity.…”
