Cov graphite uas nthuav tau yog tsim los ntawm ob txoj kev

Cov graphite uas nthuav tau yog tsim los ntawm ob txoj kev: tshuaj lom neeg thiab electrochemical. Ob txoj kev no txawv ntxiv rau cov txheej txheem oxidation, deacidification, ntxuav dej, dehydration, ziab thiab lwm yam txheej txheem zoo ib yam. Qhov zoo ntawm cov khoom ntawm feem ntau ntawm cov chaw tsim khoom siv cov txheej txheem tshuaj lom neeg tuaj yeem ncav cuag cov ntsuas teev tseg hauv GB10688-89 "graphite nthuav tau" tus qauv, thiab ua tau raws li cov khoom siv rau kev tsim cov ntawv graphite yooj ywm thiab cov qauv xa khoom.

Tab sis kev tsim cov khoom tshwj xeeb uas tsis tshua muaj zog (≤10%), cov ntsiab lus sulfur tsawg (≤2%) ntawm cov khoom nyuaj, cov txheej txheem tsim khoom tsis dhau. Kev txhim kho kev tswj hwm kev txawj ntse, kawm cov txheej txheem intercalation kom zoo, tswj hwm kev sib raug zoo ntawm cov txheej txheem tsis thiab kev ua tau zoo ntawm cov khoom, thiab tsim cov graphite zoo ruaj khov yog cov yuam sij los txhim kho qhov zoo ntawm cov khoom tom ntej. Qingdao Furuite Graphite cov ntsiab lus: txoj kev electrochemical tsis muaj lwm cov oxidants, cov graphite flake ntuj thiab anode pabcuam ua ke tsim ib lub chamber anode soaked hauv concentrated sulfuric acid electrolyte, los ntawm kev ncaj qha tam sim no lossis pulse tam sim no, oxidation tom qab ib lub sijhawm kom coj tawm, tom qab ntxuav thiab ziab yog graphite nthuav dav. Qhov tseem ceeb tshaj plaws ntawm txoj kev no yog tias qib tshuaj tiv thaiv ntawm graphite thiab cov ntsuas kev ua tau zoo ntawm cov khoom tuaj yeem tswj tau los ntawm kev kho cov kev ntsuas hluav taws xob thiab lub sijhawm tshuaj tiv thaiv, nrog rau kev ua qias me me, tus nqi qis, ruaj khov zoo thiab kev ua tau zoo heev. Nws yog qhov ceev kom daws qhov teeb meem sib tov, txhim kho kev ua haujlwm thiab txo qhov kev siv hluav taws xob hauv cov txheej txheem intercalation.

Tom qab deacidification los ntawm ob qho txheej txheem saum toj no, qhov sib piv ntawm sulfuric acid wetting thiab adsorption ntawm graphite interlamellar compounds tseem yog li 1: 1, kev siv cov neeg sawv cev intercalating yog loj, thiab kev siv dej ntxuav thiab dej phwj tuaj ntau. Thiab feem ntau cov chaw tsim khoom tsis tau daws qhov teeb meem ntawm kev kho dej khib nyiab, nyob rau hauv lub xeev ntawm kev tso tawm ntuj, kev ua qias tuaj ib puag ncig yog qhov loj heev, yuav txwv tsis pub kev loj hlob ntawm kev lag luam.
