Dear Colleagues,

The 2019 Nobel Prize in Chemistry was awarded to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino in recognition of their significant contributions to the development of lithium-ion batteries. Since Dr. Goodenough demonstrated the use of cobalt oxide as a cathode material in 1980 and Yoshino created the first commercially viable lithium-ion battery in 1985, research and industrial practices involving lithium-ion batteries have made great progress. In recent years, with the rapid expansion of the electric vehicle industry, the lithium-ion battery has gained significant attention as a core component in these vehicles. However, with great power comes great responsibility. The rapid development of electric vehicles, energy storage systems, and 3C electronics industries has put forward higher requirements for the energy density, power density, cycle performance, and safety of lithium-ion batteries. Electrode materials (including cathode materials and anode materials) are the key indicators of the energy performance of batteries. Recent research on doping modification of traditional cathode and anode materials and the development of new electrode materials has greatly promoted progress in the industry, such as the industrialization of high-nickel NCM cathode materials and silicon carbon anode materials. Additionally, studies on all-solid-state lithium batteries developed as a means to improve the safety and energy density of liquid electrolyte lithium-ion batteries and improvements in the electrode material recycling industry have entered the pilot-scale stage. However, to meet the requirements for use in wearable bioelectronics, current all-solid-state lithium batteries must surmount challenges in stretchability and durability while withstanding the strain induced by the skin or tissues. Thus, the development of stretchable and healable electrodes, higher-performance binders, and stable solid or gel electrolytes could significantly increase the lifetime of all-solid-state lithium batteries and contribute to the commercialization of wearable lithium-ion batteries in electronic devices. To further summarize and report recent advances in the research on electrode materials and their applications in wearable lithium-ion batteries and bioelectronics, this Special Issue was launched to provide a dedicated platform for the exchange of academic findings across related fields. This issue strives to deepen the academic and industrial knowledge on new technologies and novel electrode materials through discussions on related issues to promote the progress and implementation of these exciting technologies.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
