{"product_id":"cazibcv2o5np","title":"Vanadium Pentoxide (V2O5, \u003e99.9%) Nanopowder (~50 nm) for Aqueous Zn-Ion Battery Cathode, 50-100 g\/Bottle, CAZIBCV2O5NP","description":"\u003cp\u003eVanadium pentoxide (V2O5) nanopowder is one of the most extensively studied and high-performance intercalation cathode materials for aqueous zinc-ion batteries (AZIBs).Due to its layered or open orthorhombic framework, multi-valence vanadium redox chemistry (V^{5+}\/V^{4+}\/V^{3+}), and high theoretical capacity, it serves as a benchmark host for divalent zinc ion insertion.\u003c\/p\u003e\n\u003cp\u003eThe key electrochemical advantages of the V2O5 nanopowder for aqueous Zn-Ion battery are: (1) \u003cstrong\u003eReversible Zn^{2+} Intercalation and Deintercalation\u003c\/strong\u003e: During discharge, zinc ions (Zn^{2+}) intercalate into the interlayer galleries of the V2O5 crystal lattice, accompanied by the reduction of vanadium ions from V^{5+} to lower oxidation states (V^{4+} and V^{3+}). Upon charging, Zn^{2+} ions are extracted, reversing the process. (2) \u003cstrong\u003eProton Co-Intercalation\u003c\/strong\u003e: In many mild aqueous systems (such as ZnSO4 electrolytes), a concurrent proton (H+) co-intercalation mechanism often occurs due to minor localized pH fluctuations near the cathode surface. This dual-ion insertion helps maintain structural charge balance and contributes to high initial capacities.\u003c\/p\u003e\n\u003cp\u003eThe nanosize dimension brings the following advantages: (1) \u003cstrong\u003eShortened Solid-State Diffusion Paths\u003c\/strong\u003e: Divalent zinc ions (Zn^{2+}) possess a high charge density and strong electrostatic interactions with host lattice oxygen atoms, resulting in intrinsically sluggish solid-state diffusion. Scaling V2O5 down to the nanoscale (e.g., nanoparticles, nanobelts, or ultra-thin nanosheets) drastically reduces the diffusion distance required for Zn^{2+}, accelerating charge-transfer kinetics. (2) \u003cstrong\u003eEnhanced Electrochemically Active Surface Area\u003c\/strong\u003e: A high surface-to-volume ratio maximizes contact with the aqueous electrolyte, exposing more active redox sites and lowering local interfacial resistance. (3) \u003cstrong\u003eMechanical Stress Accommodation\u003c\/strong\u003e: Nanostructured architectures can better accommodate the localized lattice expansion and contraction that occurs during repeated ion insertion and extraction, preventing premature structural pulverization.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100.036%; height: 284.8px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCAZIBCV2O5NP (C-AZIB-C-V2O5NP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1314-62-1\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eyellow-orange powder\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003eMolar Mass\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e181.88 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003eParticle Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eD50 =~ 50 nm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003eDensity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e3.35 g\/mL at 25 °C (lit.)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.6898%; height: 35.6px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.1319%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e50 g and 100 g\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/adma.202001469\"\u003e\u003cspan\u003eK.
