Special Issue Information

Dear Colleagues,

This Special Issue, “Preparations and Applications of Polymer–MXenes Composites for Next Generation Energy Storage,” aims to highlight the rapidly expanding field of advanced hybrid materials that integrate the unique electronic, mechanical, and structural properties of MXenes with the versatility and processability of functional polymers. By combining conductive two-dimensional transition metal carbides/nitrides with a wide range of natural and synthetic polymers, these composites offer promising solutions to overcome current limitations in electrochemical energy storage, including conductivity, stability, flexibility, and interfacial compatibility.

The Issue will cover topics such as innovative synthesis and fabrication strategies for polymer–MXene composites, structure–property relationships, interfacial engineering, and their applications in lithium-ion, sodium-ion, zinc-ion, and emerging multivalent batteries, as well as supercapacitors and flexible/wearable devices. Contributions that bridge fundamental understanding with practical implementation, such as scalable preparation methods, in situ characterization, and performance optimization under extreme conditions, are particularly encouraged.

We welcome both original research articles reporting cutting-edge experimental or computational advances and comprehensive review papers that provide critical insights into future directions of polymer–MXene composite research in the context of next-generation energy storage technologies.

Polymer-engineered MXene composites have emerged as a versatile materials platform for electrochemical energy storage, offering a means to address key limitations associated with ion transport, structural instability, and interfacial reactivity. This review provides a unified perspective on how polymer integration modifies the structure–transport–stability relationships of MXene-based systems across Na-ion batteries, aqueous Zn-ion batteries, and supercapacitors. In Na-ion systems, polymer-mediated interlayer engineering and porosity control improve ion accessibility and mitigate diffusion limitations arising from the large ionic radius of Na+. In aqueous Zn-ion systems, polymer electrolytes and interfacial layers regulate Zn2+ solvation and deposition behavior, suppressing dendritic growth and parasitic reactions. In supercapacitors, polymer–MXene hybrids establish coupled ionic–electronic transport pathways and mechanically compliant architectures, enabling stable electrochemical performance under high-rate and deformable conditions. Particular emphasis is placed on the underlying mechanisms responsible for suppressing oxidation, preserving structural integrity, and extending cycle life, including interfacial passivation, desolvation regulation, and structural confinement. These coupled effects govern long-term electrochemical stability across different energy storage systems. Finally, recent advances in operando characterization, data-driven materials design, and scalable processing are discussed in the context of future development. By linking material design strategies to fundamental mechanisms, this review outlines a coherent framework for the rational development of polymer–MXene composites toward practical energy storage applications.

MXene–polymer hybrids combine the high in-plane conductivity and rich surface chemistry of MXenes with the processability and mechanical tunability of polymers for lithium-metal and lithium–sulfur batteries. Most reported systems still rely on HF-etched MXenes, introducing F-rich terminations, safety and waste issues, and poorly controlled surfaces. This review instead centers on fluoride-free synthesis routes, benchmarks them against HF methods, and translates route–termination relationships into practical rules for choosing polymer backbones. We track the evolution from early linear hosts such as PEO- and PVDF-type polymers to polar nitrile or carbonyl matrices, crosslinked and ionogel networks, and emerging biopolymers and COF-type porous frameworks that are co-designed with MXene terminations to regulate ion transport, interfacial chemistry, and mechanical robustness. These chemistry–backbone pairings are linked to five scalable fabrication modes, including solution blending and film casting, in situ polymerization, surface grafting, layer-by-layer assembly, and electrospinning, and to roles as solid or quasi-solid electrolytes, artificial interphases, separator-like coatings, and electrode-facing architectures. Finally, we highlight key evidence gaps and reporting standards needed to de-risk scale-up of green MXene–polymer batteries. Full article
