N-doped porous carbon materials possess abundant pores and nitrogen functionalities, holding significant potential for supercapacitors. However, achieving precise control of the pore structure to enhance electrochemical performance remains challenging in large-scale production commercial electrode materials. Herein, Chinese yam, a rhizome plant rich dopamine, is selected as precursor prepare N,O-codoped hierarchical (N/O-PC-3) via one-step carbonization activation process. The precisely controlled by adjusting degree aggregation zinc-containing hydrolysates biomass through synergistic action ZnCl2 (activating agent) NH4Cl (nitrogen source).

With the rapid development of new energy industry, supercapacitors have become key devices in field storage. To forecast remaining useful life (RUL) supercapacitors, we introduce a technology that integrates variational mode decomposition (VMD) with bidirectional long short-term memory (BiLSTM) neural network. Firstly, aging experiments under various temperatures and voltages were carried out to obtain data. Then, VMD was implemented decompose data, which helped eliminate disturbances, including capacity recovery test errors. hyperparameters BiLSTM adjusted, employing sparrow search algorithm (SSA) improve consistency between input data network structure. After obtaining optimal BiLSTM, decomposed into for prediction. The experimental results showed VMD-SSA-BiLSTM model proposed this paper has high prediction accuracy robustness different voltages, an average RMSE 0.112519, decrease 44.3% compared minimum 0.031426.

Abstract Here, poly( N ‐acryloylglycinamide‐ co ‐vinyltriazole) p(NAGA‐ ‐VTZ) supramolecular polymer hydrogel doped with carbonized and activated polypyrrole nanotubes as a high‐strength self‐healable material is presented for supercapacitors. Initially, the films are synthesized by photopolymerization of ‐acryloylglycinamide 1‐vinyl‐1,2,4‐triazole without use any cross‐linkers. The hydrogels demonstrated remarkable self‐healing ability via hydrogen bonding at temperatures above upper critical solubility temperature, excellent mechanical properties (0.86 MPa), large stretchability (1300%) cut resistance. Subsequently, ethanol/KOH‐activated (acNTs) prepared active electrochemical double‐layer capacitors (EDLC). Then, symmetric supercapacitor employing hydrogel, acNTs aqueous 3 m KCl solution assembled. Cyclic voltammetry galvanostatic charge–discharge measurements show that device gives specific capacitance 282.62 F g −1 0.2 A high areal 316.86 mF cm −2 scan rate 10 mV s . Importantly, operates over wide voltage window (0–1.2 V) provides cyclic performance retention 97% after 000 cycles 94% self‐healing. In summary, developed exhibits considerable potential high‐performance energy storage device.
