{"product_id":"clibcnlfphrwt","title":"Nanosize LiFePO4 (LFP) Powder with High-Rate (20C) and Wide Temperature (-40 to 60℃) for Li-Ion Battery Cathode, 100 g\/bottle, CLIBCNLFPHRWT","description":"\u003cp\u003eTo achieve high-rate performance in LiFePO4 (LFP) over a wide temperature range (typically defined as -30°C to +60°C), synthesis must overcome the material's intrinsic 1D lithium-ion diffusion path and low electronic conductivity.\u003c\/p\u003e\n\u003cp\u003eTo push LFP to high rates (10C to 50C), the goal is to shorten the diffusion distance (L) for lithium ions, as the diffusion time is proportional to L^2. Typically the following strategies are explored: (1) \u003cstrong\u003eNano-structuring\u003c\/strong\u003e: Reducing primary particle size to \u0026lt;100 nm. This is often achieved via solvothermal synthesis or solution combustion, which yield smaller, more uniform particles than traditional solid-state methods. (2) \u003cstrong\u003e3D Conductive Networks\u003c\/strong\u003e: Moving beyond simple amorphous carbon. Using Graphene or Carbon Nanotubes (CNTs) creates a \"superhighway\" for electrons, ensuring the entire electrode surface is active even during rapid pulses. (3) \u003cstrong\u003eSurface Coating (Ga, Metal Oxides)\u003c\/strong\u003e: Recent research shows that coating LFP with metals like Gallium or oxides like Al2O3 can improve electronic density without sacrificing tap density, providing a more robust electron-conduction shell than carbon alone.\u003c\/p\u003e\n\u003cp\u003eThe \"bottleneck\" in cold weather is the charge transfer resistance (Rct) at the cathode\/electrolyte interface. (1) \u003cstrong\u003eBulk Doping\u003c\/strong\u003e: Substituting Fe^{2+} with ions like Mg^{2+}, Zr^{4+}, or V^{5+} slightly expands the lattice or creates defects that lower the activation energy for lithium-ion hopping. (2) \u003cstrong\u003eInterfacial Engineering\u003c\/strong\u003e: Using \"soft\" carbon sources (like phytic acid or citric acid) during synthesis creates a more permeable carbon layer that facilitates faster ion desolvation. (3) \u003cstrong\u003eElectrolyte Synergies\u003c\/strong\u003e: While the cathode is the focus, LFP synthesized with a high surface area requires electrolytes with low-viscosity solvents (like carboxylates) and additives (like LiDFP or LiBOB) to maintain a thin, conductive SEI at sub-zero temperatures.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eThe high-rate LFP powders are surface coated with carbon (2.5 wt%) for improving stability and conductivity.\u003c\/span\u003e \u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 385.387px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 41.95px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 41.95px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 41.95px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCLIBCNLFPHRWT (C-LIB-C-NLFPHRWT)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 38.375px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 38.375px;\"\u003e\n\u003cstrong\u003e \u003c\/strong\u003e\u003cem\u003eParticle Size Distribution\u003c\/em\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 38.375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eD10 = 0.23 um;  \u003c\/span\u003e\u003cspan\u003eD50 = 0.65 um;   D90 = 3.18 um\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003eMain Component Content\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e\n\u003cp\u003e\u003cspan\u003eLi: 4.3 wt%,   Fe: 32.9 wt%,  P: 20.2 wt%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6331%;\"\u003e\u003cem\u003eCarbon Content\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%;\"\u003e\n\u003cp\u003e\u003cspan\u003e2.5 wt%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.3625px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 23.3625px;\"\u003e\u003cem\u003eTap Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 23.3625px;\"\u003e\u003cspan\u003e0.65 g\/cm3\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.3625px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 23.3625px;\"\u003e\u003cem\u003eSpecific Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 23.3625px;\"\u003e17.8 m2\/g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 23.3625px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 23.3625px;\"\u003e\u003cem\u003eWater Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 23.3625px;\"\u003e577 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 162.3px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 162.3px;\"\u003e\u003cem\u003eFirst Discharging Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 162.3px;\"\u003e\n\u003cp\u003e158.3 mAh\/g (2.0-3.7 V, 0.1 C)\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBCNLFPHRWT_Discharge_Efficiency_160x160.png?v=1769905947\" style=\"margin-bottom: 16px; float: none;\" width=\"185\" height=\"102\"\u003e   \u003cimg height=\"111\" width=\"131\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CLIBCNLFPHRWT_02_160x160.png?v=1769905947\" style=\"margin-bottom: 16px; float: none;\"\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 30.725px;\"\u003e\n\u003ctd style=\"width: 33.6331%; height: 30.725px;\"\u003e\u003cem\u003eFirst Columbic Efficiency\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0072%; height: 30.725px;\"\u003e\n\u003cp\u003e96.9% \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: (1) Please store the nanosize LFP powder in a dry area (glovebox is preferred); \u003c\/span\u003e\u003cspan\u003e(2) The battery powder is highly recommended to be dried at 80-100°C in a vacuum oven for 6-12 h before use. \u003c\/span\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\u003cspan\u003e\u003ca href=\"https:\/\/advanced.onlinelibrary.wiley.com\/doi\/abs\/10.1002\/aenm.201300159\"\u003eX.
