Special Issue Information

Dear Colleagues,

The increasing demand for sustainable energy solutions and environmental protection has accelerated the development of advanced electrochemical applications. Electrochemistry is integral to the innovation of novel batteries, sensors, and other technologies that address energy and environmental challenges. This Special Issue aims to showcase the latest advancements in electrochemistry applications related to energy and the environment, with an emphasis on battery and sensor technologies.

Batteries have become essential in modern society, powering everything from portable electronics to electric vehicles and renewable energy systems. Beyond Li-ion batteries, groundbreaking electrochemistry research enables for next-generation batteries, such as Na-ion, K-ion, Zn-ion, and Al-ion batteries. Electrochemical sensors represent another vital application in the energy and environment sectors. These sensors facilitate the detection and monitoring of various environmental parameters, including water quality, air quality, soil contamination, and greenhouse gas emissions, contributing to the preservation and enhancement of our planet's ecosystems.

In addition to batteries and sensors, numerous other electrochemistry applications are shaping the energy and environmental landscape. Fuel cells, electrochemical water treatment methods, and CO2 reduction and conversion techniques are also significant, contributing to the promotion of a circular economy. This Special Issue highlights the essential role of electrochemistry in developing sustainable energy solutions and protecting the environment. Therefore, this Special Issue invites original research papers, short communications, and review articles that explore a wide range of electrochemistry applications in energy and environment sectors:

  1. Energy storage and conversion technologies, including novel battery technologies (e.g., lithium-ion, sodium-ion, potassium-ion batteries), solar cells, thermoelectric generators, and fuel cells, contributing to sustainable energy solutions.
  2. Environmental sensing, focusing on the development and implementation of electrochemical sensors for monitoring water quality, air quality, soil contamination, and greenhouse gas emissions, promoting environmental protection and resource management.
  3. Cell-based water treatment processes, such as electrocoagulation, electrooxidation, and electrodialysis, offer effective solutions for removing pollutants and contaminants from water. These innovative methods utilize small-scale devices that harness the power of electrochemistry to treat water and ensure its quality.
  4. Small-scale electrochemical CO2 reduction and conversion methods, transforming carbon dioxide emissions into valuable chemicals and fuels using cells. These innovative approaches offer a sustainable solution to reducing greenhouse gas emissions, contributing to the overall effort of combating climate change and promoting a greener future. We eagerly anticipate your valuable contributions to this Special Issue and look forward to showcasing the latest advancements in electrochemistry applications for energy and environmental sustainability.

Red phosphorus (rP) is one of the most promising anode materials for lithium-ion batteries, owing to its high theoretical capacity. However, its low electronic conductivity and large volume expansion during cycling limit its practical applications, as it exhibits low electrochemical activity and unstable cyclability. To address these problems, tellurium (Te)-rP-C composites, which have active materials (Te, rP) that are uniformly distributed within the carbon matrix, were fabricated through a simple high-energy ball milling method. Among the three electrodes, the Te-rP (1:2)-C electrode with a 5% FEC additive delivers a high initial CE of 80% and a high reversible capacity of 734 mAh g−1 after 300 cycles at a current density of 100 mA g−1. Additionally, it exhibits a high-rate capacity of 580 mAh g−1 at a high current density of 10,000 mA g−1. Moreover, a comparison of the electrolytes with and without the 5% FEC additive demonstrated improved cycling stability when the FEC additive was used. Ex situ XRD analysis demonstrated the lithiation/delithiation mechanism of Te-rP (1:2)-C after cycling based on the cyclic voltammetry results. Based on the electrochemical impedance spectroscopy analysis results, a Te-rP-C composite with its notable electrochemical performance as an anode can sufficiently contribute to the battery anode industry.
