Electrochemistry is a subject with a long history but full of vitality. Since Galvani discovered animal electrical phenomenon in 1791, electrochemistry has experienced several vigorous development periods. Electrochemistry is a subject that studies the transformation between electric energy and chemical materials. It is an important subject across the two fields of fundamental science (Science) and applied science (Engineering and Technology). The traditional idea is that electrochemistry is mainly about the conversion between electric energy and chemical energy, such as electrolysis and battery. However, electrochemistry is not limited to the electrochemical reaction, but also includes other physicochemical processes, such as electrochemical biosensor, photo electrochemistry, electroplating and corrosion. With the development of new technologies, such as spectroscopy, mass spectrometry, microscopy and computational simulation, electrochemical studies were largely reshaped.
At present, with the increasing demand for traditional energy replacement, the carbon peaking and carbon neutrality goals put on the agenda, the needs of clean energy vehicles and so on, the electrochemistry has ushered in the third golden development period. With the development of energy, material, environment, information, biomedicine and other areas, more and more talented researchers enter the field of electrochemistry. The number of participants in the national electrochemical annual conference has increased exponentially in the past decade. In 2019, the actual number of participants of the 20th National Electrochemical Society exceeded 5000.
In recent years, there have been many new frontier and hot topics in both fundamental and applied electrochemistry. In the field of electrochemical interface, the interface microstructure, high spatial temporal resolution method, adsorption kinetics and theoretical modeling are all at the key nodes to break through the limitations of previous limit. In the foreseeable future, there will be more breakthroughs in atomic and molecular level mechanisms and models. In the field of electrocatalysis, it has focused on the materials science, which has developed rapidly and stimulated by the need of fuel cell technology. With the increasing demand for renewable energy such as solar energy, perovskite based solar cells have become a hot spot. The trillion-dollar industrial supply chain of electrical vehicles has been spread all over the world. Energy conversion and storage will also be the key direction in the future and will play an important role in the fields of environment and economy. With the emergence of new technologies and concepts such as brain computer interface and metauniverse, the combination of microcircuit chip and bioelectrochemistry will be the next technological revolutions.
This special collection (consecutively published in the journal’s February and March issues) consist of a series of review and research articles on cutting-edge experimental technologies and theoretical methods, including synchrotron characterization technology, electrochemical voltammetry and chronoamperometry, the application of magnetic resonance in metal ion batteries, application of electrical transport spectroscopy in in-situ electrochemical interface measurement, single nanoparticle electrochemical measurement technology, and application of Mossbauer spectroscopy in electrocatalysis, electrochemical double-layer modeling and theoretical simulations of electrocatalysis based on the machine learning. The research progress of brain electrochemistry, application of various in-situ technologies in ORR research, development of electrochemical materials and research advances in fuel cells and batteries will also be introduced in detail in the special issue.
The booming electrochemistry will certainly bring more breakthroughs to technologies and leading economic development in near future and beyond.
Finally, we would like to express our heartfelt thanks to all the authors, reviewers and editorial staff for their hard and fruitful work!
