Novel Fe<sub>3</sub>O<sub>4</sub>@Ti<sub>3</sub>C<sub>2</sub> MXene hybrid exhibits great promise as a high volumetric performance anode material for lithium ion batteries.
Solid polymer electrolytes are considered among the most promising candidates for developing practical solid-state sodium batteries. However, moderate ionic conductivity and narrow electrochemical windows hinder their further application. Herein, inspired by Na+/K+ conduction in biological membranes, we report a (-COO-)-modified covalent organic framework (COF) as Na-ion quasi-solid-state electrolyte with sub-nanometre-sized Na+ transport zones (6.7-11.6 Å) created adjacent -COO- groups COF...
Ultramicroporous carbon materials with uniform pore size accurately adjusted to the dimension of electrolyte ions or CO 2 molecule are highly desirable for maximizing specific capacitance and uptake. However, efficient ways fine‐tuning ultramicropore at angstrom level scarce. A completely new approach precisely tuning sub‐angstrom is proposed herein. Due varying activating strength alkali ions, can be finely tuned in range 0.60–0.76 nm as activation ion varies from Li + Cs . The carbons...
Abstract The intercalation capacity at low potential of carbon‐based anode plays a significant role for developing potassium ion batteries (PIBs) with high energy density. However, the inferior rate and cyclic performance caused by repeated insertion/extraction large K + tremendously restricts practical application PIBs.

Abstract Noncovalent modification of carbon materials with redox‐active organic molecules has been considered as an effective strategy to improve the electrochemical performance supercapacitors. However, their low loading mass, slow electron transfer rate, and easy dissolution into electrolyte greatly limit further practical applications. Herein, this work reports dual (1,5‐dihydroxyanthraquinone (DHAQ) 2,6‐diamino anthraquinone (DAQ)) cooperatively confined in‐between edge‐oxygen‐rich...
A simple but efficient template carbonization method was prepared to covalently graft <italic>p</italic>-phenylenediamine molecule onto hollow “bubble-like” carbon spheres (PPD–BC) surface as the negative electrode for high performance asymmetric supercapacitors.
Abstract With the rapid development of mobile electronics and electric vehicles, future supercapacitors focuses on not only high energy power densities but also device minimization lightweight. Although activated carbon based an double‐layer mechanism has been used in commercialized supercapacitors, it is unsatisfied with ever‐increasing demands for a limited space. Therefore, urgent design preparation advanced electrode materials both gravimetric volumetric performance without sacrificing...
