Special Issue Information

Dear Colleagues,

Lithium-ion batteries have emerged as critical electrochemical devices, essential, customizable, and important power sources for vehicles and large-scale energy storage systems. As one of the most important components, the materials, including positive and negative electrode materials, play a significant role in the improvement of the performance of lithium-ion batteries. Indeed, the rational design and preparation of various nanomaterials for LIB application has attracted huge attention from researchers worldwide in recent decades, and it has been a major research theme for the development of high-performance batteries.

The main aim of this Special Issue is to publish original research articles on the current state and future trends in the field of LIB materials. Review articles by experts in the field are also welcomed if they contribute to defining the direction in which research and new applications will evolve.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly 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 2700 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.

Self-assembled liquid crystal polymer networks build directional transport channels via molecular alignment, enabling efficient and ordered lithium-ion migration, while single-ion conducting polymer electrolytes improve lithium-ion transference number by covalently anchoring anions, which alleviates concentration polarization and effectively suppresses lithium dendrite growth. Herein, a series of substrate-free Li salt-grafted cholesteric liquid crystal elastomers (CLCE) with tunable helical pitches and spiral orientation were fabricated, and quasi-solid electrolyte membranes were obtained through plasticization. It was found that samples with the smallest helical pitch delivered the highest lithium-ion transference number irrespective of the spiral orientation. The optimal CLCE electrolyte membrane achieved a lithium-ion transference number of 0.94, exhibiting characteristic single-ion conductivity. Moreover, after adding small amount of extra free Li salt, the prepared electrolyte membrane delivered a room-temperature ionic conductivity of 2.6 × 10−4 S·cm−1, an electrochemical stability window of 5.2 V and stable cycling performance, providing new insights into the design of high-performance safe quasi-solid lithium-ion batteries.

Trace amounts of H2O are inevitably introduced during lithium battery manufacturing processes, which induces the hydrolysis of LiPF6, leading to HF formation, which triggers a cascade of deleterious reactions that degrade the solid electrolyte interphase (SEI) and corrode electrode materials. In this work, a water-scavenging electrolyte was constructed by employing a boroxine-linked covalent organic framework (COF) as the suspended phase. The ring-opening reaction of the boroxine ring units in COFs can effectively capture H2O, thereby suppressing the hydrolysis of PF6− and mitigating electrode corrosion caused by HF. Consequently, a Li-metal battery with a high-nickel cathode retained 73% of its initial capacity after 500 cycles at 1 C, and a silicon-based lithium-ion battery with a high-nickel cathode sustained stable cycling over 500 cycles at a high rate of 10 C. This suspension strategy, leveraging a boroxine-linked COF with dual H2O-scavenging capability, offers a scalable and versatile platform for electrolyte engineering toward practical next-generation lithium batteries.
