“…However,i tc an be seen that the R ct of PTAPP-NC is lower than that of PTAPP-NS, and the result also supported the highers pecific capacity of PTAPP-NC.M oreover,t he slope of the PTAPP-NC anode of the linear line in the low frequencyi sl arger than PTAPP-NS and PTAPP-blank, indicating the lower diffusive resistivity of PTAPP-NC and its quick ion motion in the host solid-state phase. [24] The above electrochemical measurements adequately demonstrate that PTAPP-NC electrode exhibits outstanding rate performance and long cycle stability at high currentd ensity. This result can be attributedt ot he highly conjugated chemical structureo fp orphyrin, which is of benefit for the charge-transfer reaction and not destroyed easily.I na ddition, the unique layer-by-layered structure would shorten the diffusiond istance during the insertion/extraction of lithium ions, and provide more spaces for electrolyte, thus improving the lithium storage performance.…”

The precise regulation of nucleation growth and assembly of polymers is still an intriguing goal but an enormous challenge. In this study, we proposed a pre‐polymerization strategy to regulate the assembly and growth of polymers by facilely controlling the concentration of polymerization initiator, and thus obtained two kinds of different nanosheet‐based porphyrin polymer materials using tetrakis‐5,10,15,20‐(4‐aminophenyl) porphyrin (TAPP) as the precursor. Notably, due to the π–π stacking and doping of TAPP during the preparation process, the obtained PTAPP‐nanocube material exhibits a high intrinsic bulk conductivity reaching 1.49×10−4 S m−1. Profiting from the large π‐conjugated structure of porphyrin units, closely stacked layer structure and excellent conductivity, the resultant porphyrin polymers, as electrode materials for lithium ion batteries, deliver high specific capacity (≈650 mAh g−1 at the current density of 100 mA g−1), excellent rate performance and long‐cycle stability, which are among the best reports of porphyrin polymer‐based electrode materials for lithium‐ion batteries, to the best of our knowledge. Therefore, such a pre‐polymerization approach would provide a new insight for the controllable synthesis of polymers towards custom‐made architecture and function.

“…So far, 0D nanomaterials have various types, including quantum dots, nanoparticles, nanospheres, nanocages, core–shell structures, and so forth. Typically, these 0D nanomaterials have been widely studied in energy storage field due to structural features and properties including surface effect, small size effect, and so on; especially, the small size of 0D nanomaterials possesses large surface area, providing sufficient sites for ionic adsorption [ 94 , 95 ]. Additionally, the stable structure plays a crucial role in buffering large volume expansion, like hollow 0D nanomaterials.…”

Potassium ion batteries (PIBs) with the prominent advantages of sufficient reserves and economical cost are attractive candidates of new rechargeable batteries for large-grid electrochemical energy storage systems (EESs). However, there are still some obstacles like large size of K+ to commercial PIBs applications. Therefore, rational structural design based on appropriate materials is essential to obtain practical PIBs anode with K+ accommodated and fast diffused. Nanostructural design has been considered as one of the effective strategies to solve these issues owing to unique physicochemical properties. Accordingly, quite a few recent anode materials with different dimensions in PIBs have been reported, mainly involving in carbon materials, metal-based chalcogenides (MCs), metal-based oxides (MOs), and alloying materials. Among these anodes, nanostructural carbon materials with shorter ionic transfer path are beneficial for decreasing the resistances of transportation. Besides, MCs, MOs, and alloying materials with nanostructures can effectively alleviate their stress changes. Herein, these materials are classified into 0D, 1D, 2D, and 3D. Particularly, the relationship between different dimensional structures and the corresponding electrochemical performances has been outlined. Meanwhile, some strategies are proposed to deal with the current disadvantages. Hope that the readers are enlightened from this review to carry out further experiments better.

Ti 3 C 2 has been considered as a potential material for lithium-ion storage because of its abundant surface terminals, excellent metal-like conductivity, and modifiable layered structure. However, the Li + diffusion rate in interlayer is limited by the small interlayer spacing determined by the van der Waals forces. Herein, the dehydration condensation reaction between amino-functionalized Ti 3 C 2 (Ti 3 C 2 -NH 2 ) and maleic acid (MA) molecules was utilized to enlarge the interlayer spacing of Ti 3 C 2 . The MA molecules were successfully welded into interlayers of Ti 3 C 2 by HN−CO bonds (namely, chemical welding) and MA chemical welded Ti 3 C 2 (MA-Ti 3 C 2 ) with self-adaption layered structure were obtained. The MA molecules can contribute double effects to the layered structure of Ti 3 C 2 , and they act as chains to remit the volume change during Li + insertion and serve as pillars to enhance the structure stability during Li + extraction. The MA-Ti 3 C 2 exhibits an interlayer spacing of 1.28 nm, a fast Li + diffusion rate (1.4 × 10 −8 to 5.8 × 10 −7 cm 2 s −1 ), and improved Li + storage performance. The MA-Ti 3 C 2 //AC lithium-ion capacitor (LIC) demonstrates an excellent energy density of 102.5 Wh kg −1 at 200 W kg −1 and cycle stability with 76.3% at 1.0 A g −1 after 1000 cycles. This novel chemical welding delivers an effective perspective for modifying the layered structure, enhancing the structure stability, and achieving fast Li + diffusion and high-rate capability of twodimension materials.
