In this work, we report the synthesis of nickel-cobalt phosphate dihydrate (NCP) grown directly on nickel foam using a simple hydrothermal method carried out at 180°C for 12 h. This straightforward approach yielded a distinctive flake and nanosheet morphology, resulting in abundant electroactive sites, enlarged surface area, and open channels for rapid ion diffusion. Electrochemical investigation revealed the remarkable performance of the NCP electrode. Cyclic voltammetry (CV) demonstrated a specific capacity of 118.8 C/g (215 F/g) at 5 mV/s, while galvanostatic charge-discharge (GCD) measurements confirmed a specific capacity of 98.8 C/g (178.9 F/g) at 1 A/g within a 0.55 V potential window. To evaluate practical applicability, a supercapattery device was assembled using the binder-free NCP electrode as the positive electrode and activated carbon (AC) as the negative electrode. The NCP//AC device delivered a specific capacity of 87.7 C/g at 0.5 A/g. Most notably, the device demonstrated outstanding electrochemical stability, maintaining 92.9% capacity retention after 5000 cycles at 2 A/g. These findings highlight the efficacy of the hydrothermal approach and the synergistic role of Ni and Co in stabilizing the phosphate framework. The NCP electrode, with its unique nanosheet architecture, emerges as a promising candidate for next-generation, high-performance supercapattery.</p>","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"5 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.70115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These limitations arise from the intrinsically low dielectric constant of polymer matrices that fail to effectively dissociate lithium salts. Meanwhile, the disordered ion pathways induce tortuous migration routes and nonuniform current density at electrode interfaces. This perspective introduces the concept of programming ionic transport, which integrates ferroelectric liquid crystals (LCs), dielectric field engineering, and process-programmed assembly to overcome these challenges. Ferroelectric LCs offer a unique combination of high dielectric anisotropy and programmable molecular order, enabling the creation of low-tortuosity ion highways with built-in polarization fields. The spontaneous polarization of ferroelectric nematic phases can generate local electric fields that actively repel anions and guide lithium ions, potentially overcoming the limitations of conventional SPEs. To translate this molecular order into macroscopic device function, we highlight the critical role of advanced manufacturing techniques. Process-programmed assembly, including shear-induced alignment in 3D printing and electrospinning, provides a direct means to control alignment of LCs into designed architectures. The integration of material design and digital fabrication enables electrolytes with graded dielectric properties, hierarchical ion transport networks, and customized device geometries for ASSBs.

Sc₂O₃ was incorporated at doping levels of 0.5, 1, and 2.5 wt%, and its effects were systematically investigated using several characterization techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). These analyses confirmed successful Sc₂O₃ incorporation without significant changes in the cathode morphology. Electrochemical characterizations showed that, although the initial capacity decreased with increasing Sc content, capacity retention and rate performance improved significantly. Notably, the sample doped with 1 wt% Sc₂O₃ demonstrated a discharge capacity of 195.1 mAh g⁻¹ after 100 cycles at 0.1 C, with a retention rate of approximately 93.1%. These findings highlight the efficacy of Sc₂O₃ doping as a viable strategy to enhance the electrochemical properties and commercial potential of nickel-rich layered cathodes in LIB applications.

The study demonstrates that asymptotic techniques offer both physical insight into the complex interplay of transport mechanisms—namely, lithium exchange between silicon and graphite, diffusion within active particles, and exchange between graphite and composite particles—and contribute to efficient parameter identification. A key challenge in characterising composite Si-C electrodes via GITT lies in the presence of very disparate time scales associated with the relevant transport phenomena. This fact results in a cell behaviour during the GITT test completely different with respect to homogeneous electrodes. The asymptotic framework developed here explains how the interplay among these transport phenomena affects the observed cell voltage during the experiments and why GITT tests must be adapted for reliable identification of blended electrode parameters, providing guidance for the design of such adapted experiments. Although applied here to a single pulse-relaxation cycle, the methodology is general and can be extended to other operating conditions or composite electrode systems.</p>","PeriodicalId":8807,"journal":{"name":"Battery Energy","volume":"5 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bte2.70107","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these challenges, researchers have explored BP incorporated with various nanocomposites to not only improve structural stability and conductivity of BP, but also suppress its environmental degradation and optimize its electrochemical performance. This review focuses on modification strategies such as carbon-based hybridization, metal doping, and heterostructure engineering to address these challenges.

In nanoporous carbon hosts, the CEI together with nanopore confinement plays a key role in capacity retention and long-term cycling. Yet, its spatial formation, stability, and contribution to electrochemical performance remain poorly understood, partly due to challenges in characterization caused by beam and air sensitivity. Here, we employ cryogenic transmission electron microscopy (cryo-TEM) with electron energy loss spectroscopy and energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy and electrochemical testing together with galvanostatic intermittent titration technique measurements to elucidate how carbon particle size affects CEI formation and electrochemical performance. We find that the CEI is not a uniform surface film but extends heterogeneously into the particle bulk. Mass transport during the first discharge dictates CEI development, and larger particles suffer from inactive regions due to the preferential CEI formation only in the outer regions of the particles. During extended cycling, charge transfer resistance at confined CEI/active material/carbon interfaces emerges as the dominant performance-limiting factor.

In this Perspective, we revisit the role of anionic polarizability across sulfide, halide, oxide, and mixed‑anion systems, highlighting how local tetrahedral dynamics complement global lattice effects.

This shift has intensified persistent challenges related to degradation, safety and lifecycle uncertainty. A growing body of literature examines the use of artificial intelligence (AI) and machine learning (ML) in battery modelling and management. However, most extant studies emphasise individual algorithms or isolated prediction tasks. The reliable deployment of intelligence on operational battery system receives limited attention. This perspective addresses this limitation by examining intelligent battery systems from a system-level standpoint. Intelligence is approached as an outcome of coordinated integration across sensing, learning, optimisation and management functions, rather than as an isolated algorithmic feature. Recent advances in data acquisition, performance optimisation, lifecycle modelling and predictive management are examined within a unified battery management architecture. Attention is given to practical deployment constraints, including sensing fidelity, data representativeness, interpretability, scalability and compatibility with embedded control systems. Evidence from fast charging studies and grid-scale deployments highlights both the potential of AI-driven approaches and the structural barriers that restrict translation from laboratory settings to real-world operation. The analysis highlights the role of early and diverse sensing, physics-informed learning, uncertainty-aware decision processes and deployment-oriented model design in shaping dependable system-level intelligence.
