“…As shown in Figure a,b, the peak currents of the NiBi 3 and Bi CV curves are increased with the scan rate during 0.2 to 2.0 mV s −1 . According to the previous study, [ 21a,b,25 ] the fitted b ‐value of the log( i ) vs log( v ) plots of NiBi 3 (Figure S14a, Supporting Information) and Bi (Figure S14b, supporting information) anode reflect the reaction kinetics of the electrode. As shown in Figure 5c, the fitted b ‐value for R 1 , R 2 , O 2 , and O 1 peaks of Bi is 0.519, 0.515, 0.522, and 0.493, respectively, which is close to 0.5.…”

Layer‐structured Bismuth (Bi) is an attractive anode for Na‐ion and K‐ion batteries due to its large volumetric capacity and suitable redox potentials. However, the cycling stability and rate capability of the Bi anode are restricted by the large volume expansion and sluggish Na/K‐storage kinetics. Herein, a structural dimensionality reduction strategy is proposed and developed by converting 2D‐layer‐structured Bi into a quasi‐one‐dimensional (quasi‐1D) structured NiBi3 with enhanced reaction kinetics and reversibility to realize high‐rate and stable cycling performance for Na/K‐ion storage. As a proof of concept, the quasi‐1D intermetallic NiBi3 with low formation energy, metallic conductivity, and three‐dimensional (3D) Na/K‐ion diffusion pathways delivers outstanding capacity retention of 94.1% (332 mAh g−1) after 15000 cycles for Na‐ion storage, and high initial coulombic efficiency (ICE) of 93.4% with improved capacity retention for K‐ion storage. Moreover, investigations on the highly reversible Na/K‐storage reaction mechanisms and cycling‐driven morphology reconstruction further reveal the origins of the high reversibility and the accommodation to volume expansion. The finding of this work provides a new strategy for high‐performance anode design by structure dimensionality manipulation and cycling‐driven morphology reconstruction.This article is protected by copyright.

“…When b value approaches 0.5, the reaction is diffusion‐controlled process, and b value approximates 1 to indicate a surface‐controlled pseudocapacitive behavior. [ 46,47 ] As displayed in Figure 4b, the b values of peaks 1, 2, 3 and 4 are calculated to be 0.855, 0.889, 1.058 and 0.898, respectively, revealing that the Zn 2+ stored procedure is mainly controlled by pseudocapacitive behavior. Furthermore, according to the formula i = k 1 v + k 2 v 1/2 , the current (i) at the specific potential can be separated into surface‐controlled pseudocapacitive effect (k 1 v) and diffusion‐controlled effect (k 2 v 1/2 ).…”

Aqueous zinc ion batteries (AZIBs) have attracted much interest in the next generation of energy storage devices because of their elevated safety and inexpensive price. Polyanionic materials have been considered as underlying cathodes owing to the high voltage, large ionic channels and fast ionic kinetics. However, the low electronic conductivity limits their cycling stability and rate performance. Herein, mesoporous Na3V2(PO4)2F3 (N3VPF) nanocuboids with the size of 80–220 nm cladded by reduced graphene oxide (rGO) have been successfully prepared to form 3D composite (N3VPF@rGO) by a novel and fast microwave hydrothermal with subsequent calcination strategy. The enhanced conductivity, strengthened pseudocapacitive behaviors, enlarged DZn2+, and stable structure guarantee N3VPF@rGO with splendid Zn2+ storage performance, such as high capacity of 126.9 mAh g‐1 at 0.5 C (1 C = 128 mA g‐1), high redox potentials at 1.48/1.57 V, high rate capacity of 93.9 mAh g‐1 at 20 C (short charging time of 3 mins) and extreme cycling stability with capacity decay of 0.0074% per cycle after 5000 cycles at 15 C. The soft package batteries also present preeminent performance, demonstrating the practical application values. In situ X‐ray diffraction, ex situ transmission electron microscopy and X‐ray photoelectron spectroscopy reveal a reversible Zn2+ insertion/extraction mechanism.

“…For Li-ion batteries, electrode materials play a crucial part in determining voltage, capacity, Li storage ability, and stability of the structure and cycling. [236][237][238][239][240] It is important to predict these properties based on the intrinsic properties of electrode materials. And finding a clear structure-function relationship would benefit researchers to gain insights into the behavior of electrode materials.…”
