Porous Electrode Materials for Zn-Ion Batteries: From Fabrication and Electrochemical Application

Abstract: Porous materials as electrode materials have demonstrated numerous benefits for high-performance Zn-ion batteries in recent years. In brief, porous materials as positive electrodes provide distinctive features such as faster electron transport, shorter ion diffusion distance, and richer electroactive reaction sites, which improve the kinetics of positive electrode reactions and achieve higher rate capacity. On the other hand, the porous structures as negative electrodes also exhibit electrochemical properties … Show more

“…Creating pores in various scales in the structure and increasing electrode thickness facilitate ion transport within the structure, which is beneficial to balancing energy and power density. An additional advantage of this design lies in its capacity for electrolyte penetration, enhancing the involvement of ions in electrochemical reactions and improving the battery performance [50][51][52][53][54][55][56][57][58][59].…”

“…It can be, e.g., ceramic [29], which has low thermal conductivity, good corrosion resistance and considerable mechanical strength. Li et al [30] reported TiN porous ceramics prepared via a freeze-drying and in situ nitridation reaction method using Ti powder and chitosan as raw materials. It showed great potential for use as sulfur host material for lithium-sulfur batteries, with a high capacity of 778 mAh/g.…”

“…Graphene/GO/reduced graphene oxide (rGO) [36] is regarded as a super lightweight and high conductivity material; it can be used in many applications, such as porous electrodes [30], supercapacitors [37], and sensors [38][39][40], etc. Chen et al [41] presented an ice template method for fabricating flexible macroporous 3D graphene sponges as the anode of microbial fuel cells (MFC), where the graphene sponge was found to be conductive, lightweight, and could recover from deformation repeatedly up to 50%.…”

“…34 In the last few years, novel electrode materials and electrolytes have been explored and new manufacturing methods have been developed to improve the electrochemical performance of ZIBs. [35][36][37] The rate of the redox reaction at the electrode, the transport rate of Zn ions, and the electron conductivity are very important factors to improve the performance of energy storage devices. 38 ZIBs use Zn or Zn-containing materials as the anode and manganese dioxide, vanadium oxide, Prussian blue, and other materials as the cathode.…”
