Neuromorphic computing integrates processing and memory functions using artificial neurons and synapses designed with electronic circuits, enabling parallel, energy-efficient data handling. One of the leading technologies supporting this paradigm is phase change memory (PCM), a non-volatile memory that stores data through reversible transitions between amorphous (high resistance) and crystalline (low resistance) states of chalcogenide materials, particularly Ge<sub>2</sub>Sb<sub>2</sub>Te<sub>5</sub> (GST225). PCM exhibits fast read/write speeds, excellent data retention, and scalability, making it ideal for neuromorphic architectures. This review highlights recent advancements in PCM for neuromorphic computing, including innovations in doping strategies and device engineering. Notable developments include arsenic-doped ovonic threshold switches (OTS) for enhanced selector performance, monolayer Sb<sub>2</sub>Te<sub>3</sub> for atomic-scale devices, and heater-all-around (HAA) 3D architectures for reduced energy consumption. Integration with machine learning tools enables precise atomistic modeling, accelerating material and device optimization. Furthermore, emerging variants like ovonic unified memory (OUM) and interfacial PCM (IPCM) offer unique performance advantages. While PCM promises significant benefits, key challenges such as resistance drift, endurance limits, and thermal crosstalk must be addressed. The global neuromorphic computing market is poised for exponential growth, driven by innovations in materials, algorithms, and architectures. The PCM and neuromorphic computing represent a transformative leap toward intelligent, adaptive, and energy-efficient computing systems.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proper temperature regulation is essential for maintaining safety, optimizing electrochemical performance, and extending cycle life. This review provides a comprehensive and structured analysis of the latest developments in battery thermal management systems (BTMS), encompassing foundational commercial systems and advanced active, passive, and hybrid cooling strategies. The discussion integrates insights from materials science, thermodynamics, systems engineering, and artificial intelligence-based control strategies. Among the most significant advancements are phase change materials (PCMs) with enhanced thermal conductivity, such as graphene-reinforced paraffin composites, which improve heat absorption and dissipation. Another key innovation is the use of microchannel liquid cooling systems, particularly those optimized through advanced topological design techniques, enabling more efficient heat transfer. Additionally, intelligent control mechanisms, including digital twin-assisted thermal management systems, allow for real-time monitoring and adaptive cooling strategies. The review critically examines the trade-offs between cooling performance, energy efficiency, and cost considerations, evaluating technologies based on key performance indicators. It also highlights several transformative developments, including self-healing thermal interface materials, 3D-printed microchannel cold plates, radiative cooling surfaces, and smart, self-regulating materials. Looking ahead, emerging frontiers such as digital twin-assisted thermal control, blockchain for lifecycle management, and quantum-optimized design are identified as promising next-generation solutions with potential to enhance scalability and sustainability.

Thermal runaway remains a major safety risk, highlighting the need for efficient battery thermal management systems (BTMS). The present work numerically investigates the effectiveness of phase change materials (PCMs) and fins in BTMS performance. An 8-cell module operating at an 8C discharge rate was selected for analysis. ANSYS-based simulations were conducted to analyze the thermal behavior of prismatic battery modules under high discharge conditions. Both organic and inorganic PCMs were evaluated, alongside fins of varied geometry, orientation, and number. Results show that high thermal conductivity PCM, such as capric acid, lowered peak battery temperatures by 36 K compared to modules without cooling. Under natural convection, vertical fins were more effective than horizontal fins, whereas under elevated convective heat transfer coefficients (50 W/m<sup>2</sup>·K), horizontal fins achieved a 31 K reduction relative to no cooling. The combined effects of high thermal conductivity and specific heat capacity of PCMs were found to be critical for thermal regulation. Optimized PCM thickness outperformed fin-only configurations in overall effectiveness. However, achieving the right balance between fins and PCM remains essential for compactness and practical design integration.

Acknowledging the complexity of the MG system and the importance of effective battery operation, this paper presents a systematic and comprehensive review on battery and energy management for RFBs.

This case study is based on actual monthly electricity consumption statistics over 1 year for a home in the Al-Latifiya district, south of Baghdad, Iraq, to install a roof PV system instead of a Diesel Generator (DG) to compensate for the interruption of the public grid.

This study investigates the impact of capacity degradation on the SoC–OCV relationship across different temperatures, aging levels, and OCV testing methods, using the CALCE and NASA battery datasets. Results show that when SoC is normalized by the degraded capacity, the SoC–OCV relationship remains nearly constant for SoC values above 20%.
