While aqueous electrolytes are the most widely employed, recent developments have also extended to non-aqueous electrolyte systems. Their intrinsic safety, low cost, and high-rate capability make them attractive for wearable, microelectronic, and autonomous systems. However, their practical implementation remains hindered by zinc anode instability, kinetic mismatch between capacitive and battery-type cathodes, electrolyte trade-offs, and scalability of complex device architectures. Herein, we address the strategies to overcome these challenges examined from a mechanism-guided and system-level perspective. Emerging device concepts including flexible, micro-ZIHSCs, self-healing systems and hybrid air-assisted configurations are discussed as viable pathways to overcome intrinsic material limitations.

To address limitations in convergence speed and estimation accuracy, this paper proposes an improved Latin Hypercube Tuna Swarm Optimization (LHTSO) algorithm. The method enhances population initialization via Latin hypercube sampling, incorporates a stage-adaptive search strategy, and introduces an elite-guidance mechanism to improve global optimization performance. An integrated LHTSO-BP-UKF framework is further developed for SOC estimation. Experimental validation is conducted under multiple driving cycles (Dynamic Stress Test (DST), New European Driving Cycle (NEDC), Federal Test Procedure (FTP), Urban Dynamometer Driving Schedule (UDDS)) and a wide temperature range (−10 to 40 °C). Results demonstrate that the proposed method consistently outperforms conventional Unscented Kalman Filter (UKF) and its variants. Under the challenging DST condition at 25 °C, the proportion of samples with estimation error exceeding 1% is reduced from 80.20% to 4.10%, achieving a 96.55% relative improvement. Moreover, the method maintains stable and bounded estimation under low-temperature conditions. These results confirm the robustness, generalization capability, and practical applicability of the proposed approach.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we propose a nested dual-inlet-dual-outlet serpentine channel LCP (NSLCP). The new structure shortens the single-path flow length of coolant, improves flow distribution uniformity, and eliminates excessive coolant temperature rise along the flow path. Thus, the heat dissipation efficiency, temperature uniformity, and system energy consumption are greatly enhanced. Results show that the thermal management system achieves significantly better overall performance with a channel width of 8 mm and a coolant mass flow rate of 2 g·s−1, compared with conventional structures. In the full operating range of 25–45 °C ambient temperatures and 0.5–2 C discharge rates, the maximum temperature and temperature difference of the battery module are controlled below 28 and 2 °C, respectively. The proposed LCP provides an innovative and practical solution for high-performance thermal management systems in large-scale energy storage stations.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ammonia has emerged as a promising carbon-free energy carrier because it can be liquefied at approximately 1 MPa under ambient conditions, has a high-octane number of about 110, and contains 17.6 wt% hydrogen, making it attractive for large-scale energy storage and transportation. This article focuses on earlier research and recent studies on technical developments in direct injection (DI) of NH3-assisted combustion. Focus on the combustion characteristics of NH3 DI in ICEs, as well as the spray characteristics, safety, and handling of NH3. This review paper develops the fundamentals of the mechanism of NH3 combustion technology, providing new insights into the application of NH3 in ICEs. Although NH3 possesses favorable storage characteristics, its application in ICEs is challenged by a high autoignition temperature (∼650 °C), low laminar flame speed (∼7 cm/s), and lower heating value (18.8 MJ/kg), which contribute to combustion instability, NOx formation, and NH3 slip. The review also explains the fundamental combustion mechanisms of ammonia and identifies key research gaps and future directions for developing efficient, low-emission ammonia-fueled internal combustion engines, supporting the transition towards sustainable and carbon-free transportation.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, under harsh operating conditions, SACs face significant challenges related to catalytic activity and structural stability. This review provides a comprehensive overview of the recent progress and future prospectives of SACs functioning under harsh environments, including high temperatures, strong acidic/alkaline media, and high-energy radiation fields. We systematically analyze the intrinsic characteristics of SACs that make them susceptible to atomic migration, aggregation, and coordination structure disruption in these harsh environments. Particular emphasis is placed on recent advances in operando characterization techniques such as in situ transmission electron microscopy, X-ray absorption spectroscopy, and multiscale simulations, which have provided critical insights into the relationships between of structure and performance. Despite progress, SACs still struggle with the trade-off between activity and stability related to dynamic reconstruction under extreme conditions. Looking ahead, SACs have broad application prospects in aerospace, deep sea exploration, nuclear waste treatment, and so on. This review aims to provide theoretical guidance and design principles for developing high-performance and robust SACs, thereby accelerating their practical deployment and sustainable utilization in next-generation clean energy technologies.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a key enabler of long-distance renewable energy transmission, Voltage Source Converter-based High-Voltage Direct Current systems have become essential infrastructure. However, line protection remains a critical bottleneck due to ultrafast fault transients, strong converter–line coupling, and sensitivity under weak-grid conditions. This review identifies three intrinsic paradoxes constraining existing methods: the speed–reliability trade-off, the laboratory–field generalization gap, and the intelligence–explainability tension. Conventional traveling-wave and differential schemes struggle to maintain robustness in multi-terminal and renewable-dominated scenarios. Data-driven approaches, including machine learning and deep learning, improve adaptability but rely on statistical correlations, leading to limited interpretability and reduced robustness under unseen conditions. To address these challenges, this review discusses an Large Language Model–Knowledge Graph-based decision-support paradigm that supports protection supervision, logic validation, adaptive setting review, and post-fault diagnosis, while retaining primary trip initiation within deterministic protection. By combining mechanism-oriented representation with semantic reasoning, this framework supports interpretable, consistent, and adaptive supervisory protection functions, paving the way for next-generation DC systems in renewable-dominated grids.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 9","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
