Anode CNT Slurry: Kev ruaj ntseg cov qauv kev ntseeg siab ntawm Next-Gen Negative Electrodes
Thaum lub cathode dictates lub zog ceev, lub anode yog lub rooj vag ntawm lub voj voog lub neej thiab kev nyab xeeb. Qhov no muaj tseeb tshwj xeeb tshaj yog thaum kev lag luam hloov mus rau Silicon-Carbon (Si-C) composites. Lub cev nthuav dav ntawm silicon thaum lub sijhawm lithiation yog qhov xwm txheej hnyav- nws tuaj yeem rhuav tshem tus qauv kev sib txuas. Shandong TanfengAnode CNT Slurryyog engineered tshwj xeeb los ua ib tug saj zawg zog, resilient "electron net" uas tuav lub anode ua ke, lub voj voog tom qab lub voj voog.
Ciaj sia nyob qhov nthuav dav: Qhov Kev Sib Tw Anode
Graphite yog qhov ruaj khov, tab sis niaj hnub siab - muaj peev xwm anodes uas muaj 5-10% Silicon ntsib qhov kev sib tw loj: ntim nthuav dav txog 300%. Ib qho kev sib txuas sib txuas (xws li cov pa roj carbon dub) tawg nyob rau hauv lub siab no. Thaum lub network puas lawm, kev sib txuas hluav taws xob poob, thiab lub roj teeb tuag.
PebAnode CNT Slurrymuab kev daws teeb meem dynamic. Cov Carbon Nanotubes tsim lub vev xaib hloov tau yooj yim, entangled web. Thaum cov silicon hais nthuav dav, CNTs flex thiab ncab ntau dua li tawg. Lawv tuav cov hluav taws xob tsis tu ncua txawm tias thaum muaj kev ntxhov siab ntawm kev them nyiaj ceev, kom ntseeg tau tias Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob (SEI) tseem nyob ruaj khov thiab cov anode khaws nws lub peev xwm ntau dua txhiab lub voj voog.
Structural Stability: Carbon Black vs Anode CNT Slurry
Cov kev xav tau ntawm tus neeg sawv cev anode yog qhov txawv ntawm cov cathode, tsom hnyav rau cov neeg kho tshuab resilience thiab aqueous ua.
| Qhov tseem ceeb Parameter | Ib txwm Carbon Dub (SP) | Shandong Tanfeng Anode CNT Slurry |
|---|---|---|
| Network Flexibility | Rigid thiab Brittle | Yooj yim thiab Elastic |
| Teb rau Expansion | Cracks thiab disconnects | stretches thiab tuav kev sib cuag |

Shandong Tanfeng: Masters ntawm Aqueous Dispersion
Ib qho tseem ceeb sib txawv rau kev tsim cov anode yog cov kuab tshuaj. Tsis zoo li cathodes (uas siv NMP), feem ntau anodes siv dej -raws li cov tshuab nrog CMC thiab SBR binders. Raws li qhov tshwj xeebcarbon nanotube conductive slurry chaw tsim tshuaj paus, Shandong Tanfeng tau mastered lub kos duab ntawm dispersing CNTs nyob rau hauv aqueous ib puag ncig.
1. SBR/CMC Compatibility:
Styrene-Butadiene Rubber (SBR) yog qhov kev xaiv ntawm anodes. PebAnode CNT Slurryyog pH-tuned thiab viscosity- tswj kom sib xyaw zoo nrog SBR thiab CMC (Carboxymethyl Cellulose). Peb xyuas kom meej tias qhov sib ntxiv ntawm peb cov slurry tsis destabilize lub rheology ntawm koj txheej slurry, tiv thaiv "flocculation" uas tuaj yeem ua kom puas batch.
2. "Stitching" SEI Txheej:
Fast charging thawb lithium ions mus rau hauv lub anode ntawm kev kub ceev. Qhov no tuaj yeem ua rau tsis sib xws lithium plating. Peb CNT network ua raws li daim phiaj hluav taws xob uas sib npaug ntawm qhov ceev tam sim no thoob plaws qhov chaw anode. Qhov no txhawb kev tsim cov txheej txheem SEI ib yam, inhibiting lithium dendrite kev loj hlob thiab txhim kho kev nyab xeeb ntawm cov roj teeb.
3. Plua plav-Kev koom ua ke pub dawb:
Kev tuav cov hmoov CNT qhuav hauv dej -raws li ib puag ncig yog qhov nyuaj thiab muaj kev phom sij. Los ntawm kev muab cov khoom ua ntej- dispersed slurry, peb tshem tawm qhov kev pheej hmoo ntawm cov khoom siv pa hauv huab cua hauv koj lub hoobkas. Nws sib tov tam sim ntawd rau hauv koj cov aqueous anode slurry, txuag lub sij hawm thiab txo kev ruaj ntseg raws li lub nra.
