Carbon-based materials have been considered as the most promising anode for both sodium-ion batteries (SIBs) and potassium-ion (PIBs), owing to their good chemical stability, high electrical conductivity, environmental benignity. However, due large sizes of sodium potassium ions, it is a great challenge realize carbon with reversible capacity, long cycle life, rate capability. Herein, by rational design, N-doped 3D mesoporous nanosheets (N-CNS) are successfully synthesized, which can...
Lithium-sulfur (Li-S) batteries are strongly considered as next-generation energy storage systems because of their high density. However, the shuttling lithium polysulfides (LiPS), sluggish reaction kinetics, and uncontrollable Li-dendrite growth severely degrade electrochemical performance Li-S batteries. Herein, a dual-functional flexible free-standing carbon nanofiber conductive framework in situ embedded with TiN-VN heterostructures (TiN-VN@CNFs) an advanced host simultaneously for both...
The biggest challenge of potassium-ion batteries (KIBs) application is to develop high-performance electrode materials accommodate the potassium ions large size.

Three typical electric polarizations illustrated Cole-Cole diagram. The properties can be...
Abstract Na‐Se and K‐Se batteries are attractive as a stationary energy storage system because of much abundant resources Na K in the Earth's crust. As alloy‐type Se has severe pulverization issue, one critical challenge to develop advanced is explore highly efficient stable Se‐based cathode. Herein, flexible free‐standing Se/carbon composite film prepared by encapsulation into carbon nanotube (CNT) interwoven N,O dual‐doped porous nanosheet (Se@NOPC‐CNT). The 3D interconnected CNT uniformly...
Li metal is demonstrated as one of the most promising anode materials for high energy density batteries. However, uncontrollable dendrite growth and repeated solid electrolyte interface during charge/discharge process lead to safety issues capacity decay, preventing its practical application. To address these issues, an effective strategy realize uniform nucleation. Here, a stable lithium-scaffold composite electrode (CC/CNT@Li) designed by melting lithium into 3D interconnected lithiophilic...
K-SeS2 batteries could provide a low-cost and high energy density storage system, because the earth-abundant element potassium (K) shows low reduction potential gravimetric capacity. But battery has never been reported of lack high-performance electrode materials. Herein, we design an advanced by encapsulation SeS2 in nitrogen-doped free-standing porous carbon matrix (SeS2@NCNFs). The self-supported SeS2@NCNFs achieves reversible capacity 417 mAh g–1 after 1000 cycles with 85% retention at...

Potassium-ion batteries (KIBs) are promising candidates for large-scale energy storage devices due to their high density and low cost. However, the large potassium-ion radius leads its sluggish diffusion kinetics during intercalation into lattice of electrode material, resulting in pulverization poor cycle stability. Herein, vanadium trioxide anodes with different oxygen vacancy concentrations (V2O2.9, V2O2.8, V2O2.7 determined by neutron diffraction) developed KIBs. The V2O2.8 anode is...
Two dimensional materials have been widely identified as promising microwave absorbers, owing to their large surface area and abundant interfaces. Here, a novel laminated magnetic composite derived from Mxene was designed successfully synthesized via facile hydrothermal oxidization of nickel ion intercalated Ti3C2. Highly disordered carbon sheets were obtained by low temperature oxidization, the in-situ produced TiO2 NiO nanoparticles embedded closely between them. This layered hybrid...
Multi-functional carbon fiber (CF) based composites have great potential as new-type microwave absorption materials (MAMs). However, it was still a huge challenge to integrate antioxidation and MA properties into CF composites. Herein, the SiOC ceramics coating modified fibers (SiOC/CFs) were prepared by polymer precursor pyrolysis method.
