Special Issue Information

Dear Colleagues,

Efficient, inexpensive, and sustainable energy conversion and storage techniques are critical for utilizing renewable energy sources and promoting carbon neutrality. We need more fundamental principles, functional materials, and experiments to achieve better performance or invent novel energy conversion/storage devices. This demanding boosts multidisciplinary research in many fields, such as interconversion between electricity and heat, solar energy conversion and solar fuels, hydrogen generation and storage, CO2 conversion and storage, storage batteries and supercapacitors, energy harvesting, etc. Recently, a significant number of emerging materials, structures, and devices have attracted increasingly attention. These growing hot and cutting-edge topics advance our knowledge and inform the development of next-generation solutions for efficient energy utilization.

This Special Issue aims to provide a forum for researchers to present the latest advances and perspectives in the development of advanced energy conversion and storage technologies. The topics include but are not limited to the following items:

  1. Electrode materials and structure design for batteries and supercapacitors;
  2. Membrane materials and fluid flow in flow batteries and fuel cells;
  3. Transport phenomenon and dynamics at electrode/electrolyte interfaces;
  4. Modelling, optimization, and numerical aspects of energy storage systems;
  5. Thermoelectric processes and materials;
  6. Solar energy conversion and solar fuels;
  7. Heat and mass transfer and thermal management in energy storage;
  8. Energy-harvesting devices.

P-Doped Modified Porous Carbon Derived from ZIF-8 for Enhanced Capacitive Performance
by Congxiu Guo, Guilin Li, Yujia Wu, Xuhui Wang, Yu Niu and Jiao Wu

Abstract
Porous carbon materials derived from ZIF-8 have attracted extensive research attention on account of their large surface area, tunable mesoporosity and abundant nitrogen content. However, directly carbonized ZIF-8 usually suffers from a low electronic conductivity, poor wettability and relatively low mesoporosity, which severely [...] Read more.
Porous carbon materials derived from ZIF-8 have attracted extensive research attention on account of their large surface area, tunable mesoporosity and abundant nitrogen content. However, directly carbonized ZIF-8 usually suffers from a low electronic conductivity, poor wettability and relatively low mesoporosity, which severely restricts their capacitive performance. Herein, P-doped modified carbon materials derived from ZIF-8 (ZPCs) were synthesized by using nontoxic phytic acid as a phosphorus source, followed by carbonization at high temperature. Benefiting from its relatively high specific surface area of 911.7 m2 g−1 and higher ratio of mesopores, as well as N, O and P doping, ZPC-1000 delivers the largest specific capacity, up to 219.4 F g−1 at 1 A g−1, among the prepared samples and an outstanding cycle span, retaining 100% capacity after 2000 cycles at 5 A g−1. In this work, we highlight the strategy of constructing a synergistic effect between high mesoporosity and heteroatom doping, which can greatly boost the capacitive performance of carbon materials.

Zinc–bromine redox flow battery (ZBFB) is one of the most promising candidates for large-scale energy storage due to its high energy density, low cost, and long cycle life. However, numerical simulation studies on ZBFB are limited. The effects of operational parameters on battery performance and battery design strategy remain unclear. Herein, a 2D transient model of ZBFB is developed to reveal the effects of electrolyte flow rate, electrode thickness, and electrode porosity on battery performance. The results show that higher positive electrolyte flow rates can improve battery performance; however, increasing electrode thickness or porosity causes a larger overpotential, thus deteriorating battery performance. On the basis of these findings, a genetic algorithm was performed to optimize the batter performance considering all the operational parameters. It is found that the battery energy efficiency can reach 79.42% at a current density of 20 mA cm−2. This work is helpful to understand the energy storage characteristics and high-performance design of ZBFB operating at various conditions. Full article

The ferrocyanide-based organic redox flow battery (ferrocyanide-based ORFB), based on electrochemistry, has become a potential energy storage technology due to its low price, eco-friendliness, safety, and convenience. However, its low efficiency and poor mass transfer performance hinder the application of the ORFB. The influence of the electrode shape (trapezoid, sector, and rectangle) on the mass transfer and battery performance are studied based on a numerical model, which is verified by the experiments. The results show that battery performance of the trapezoid electrode is better than that of the sector and rectangle electrode. The discharge voltage of the rectangle battery is the lowest, and the discharge voltage of the trapezoid battery is the highest. The discharge voltage of the rectangle battery is 4.47% lower than that of the trapezoid battery. The uniformity factor value of the trapezoid battery is 26.9% higher than that of the rectangle battery. The trapezoid shape is the best design for the electrode, contributing to the application of the ferrocyanide-based ORFBs. Full article

Micro/nano-motors play an important role in energy, environment, and biomedicines. As a new type of nano-motors, nanobottles attract great attention due to their distinct advantages of a large cavity, high specific surface area, bionic streamline structure, and chemotactic motion. Here, we systematically review the development of nanobottle motors from aspects of propulsion mechanisms, fabrication methods and potential applications. Firstly, three types of propulsive modes are summarized, with focus on chemical propulsion, light driving and magnetic actuation. We then discuss the fabrication methods of nanobottles, including the soft-template-based hydrothermal method and the swelling-inducement and wet-chemistry methods. The potential applications of nanobottle motors are additionally highlighted in energy, environmental, and biomedical fields. Finally, the future challenges and outlooks of nanobottle motors are discussed for the further development of this technology. Full article
