However, Si-based anodes experience internal mechanical strain, pulverization of silicon particles during charging and discharging, and poor electrical conductivity (6.7 × 10⁻⁴ S cm⁻¹). The effectiveness of various nanostructured architectures in resolving the problems with high-capacity Si anodes has been established. In this study, industrial ferrosilicon was used as a low-cost Si source, and a scalable method was introduced to construct a porous Si@C composite anode using two-step leaching–ball milling followed by heat treatment, through which porous Si nanoparticles are wrapped with multilayer carbon sheets derived from polyacrylonitrile (PAN). By encapsulating porous silicon nanoparticles with multiple layers of carbon sheets, creating a dependable framework for conductivity was made possible, ensuring fast transport of electrons, that also mitigated the changes in volume of silicon. This technique was both scalable and straightforward, utilizing cost-effective industrial ferrosilicon as a source of silicon. The nano-sized porous Si/C anode therefore achieves a steady cycling with 887.1 mAh g⁻¹ more than 200 cycles at 1 A g⁻¹ and a rate capability of 657.2 mAh g⁻¹ at 5 A g⁻¹. Also, the resulting porous Si@C powders were evaluated for their electrochemical performance as supercapacitor electrodes. The specific capacitance of the porous Si@C powders was found to be 1494 F g⁻¹ at 1 A g⁻¹, decreasing to 894 F g⁻¹ at 10 A g⁻¹. Additionally, a hybrid capacitor comprising of the porous Si@C powders and activated carbon was tested, which exhibited comparable electrochemical energy storage performance. The energy density of this hybrid capacitor was measured to be 37.2 W h kg⁻¹ at a power density of 694 W kg⁻¹. These findings demonstrate the potential of using Si-based electrodes in supercapacitors, particularly porous Si@C powders, to improve their performance.</div></div>","PeriodicalId":16811,"journal":{"name":"Journal of Physics and Chemistry of Solids","volume":"208 ","pages":"Article 113160"},"PeriodicalIF":4.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phase formation is confirmed from room temperature Rietveld refinement of X-ray diffraction data. The composite shows orthorhombic crystal structure with space-group <em>‘Pbam + Pbnm’</em> which is also well supported from Raman spectra. XPS analysis confirmed the existence of multiple valence states of magnetic ions such as Fe²⁺:Fe³⁺:Fe⁴⁺ = 41:45:14 and Mn³⁺:Mn⁴⁺ = 88:12, within experimental limit. This triggers super-exchange and double-exchange interactions thereby contributing significantly to the dielectric and magnetic order parameters. At the same time, with increase in LSMO content an increase in AFM transition temperature (T_N) close to room temperature is observed. An irreversibility in ZFC-FC data is evidenced for T &lt; 350 K along with an opening in M − H plot, indicating spin-glass behaviour and an onset of weak ferromagnetism in the composites. The latter is found to get enhanced significantly with increase in LSMO content and is also verified from Arrott plots. The dielectric measurements at 0 T and 1.3 T shows anomaly around T_N, hinting at plausible MD coupling. Further, confirmation to the intrinsic MD coupling is assisted by temperature and magnetic field variation of magnetodielectric effect (MD%) which shows enhanced MD effect effective at room temperature. This intriguing MD coupling could be attributed to inverse Dzyalonshinskii-Moriya interactions between magnetic ions present in the composite due to strong cross coupling. Lastly, from Landau free energy expression, the existence of biquadratic nature of magnetoelectric coupling (<em>P</em>^<em>2</em><em>M</em>^<em>2</em>) emerging from the coupling term ‘<em>γP</em>^<em>2</em><em>M</em>^<em>2</em>’ is established. At 300 K, <em>γ</em> is ∼1.6 × 10⁻² (emu/g)⁻² for BL70-30 and shows ∼2 % MD response – a nearly eight-fold increase as compared to parent BFO. Hence, the above outcomes highlight the significance of the composite as a viable candidate for multifunctional applications.</div></div>","PeriodicalId":16811,"journal":{"name":"Journal of Physics and Chemistry of Solids","volume":"208 ","pages":"Article 113159"},"PeriodicalIF":4.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
