Raw Material Parad Artificial Graphite Anodes

1. Product Core

Say Raw Material parad Artificial Graphite Anodes et sakey a functional powder material ya imparaan panamegley na saray proseson eksakto a singa say pre-carbonization, crushing, purification, tan grading, ya walay high-purity needle coke, petroleum coke, odino coal-based coke bilang manunan substrate. Saya so manunan sengegan na produksyon na artipisyal ya graphite negative electrodes parad lithium batteries. Say manunan kablian to et say pangiter na atagey-kalidad iran substrate parad ontumbok a panagproseso na graphitization diad panamegley na eksakton regulasyon na kemikal a komposisyon tan pisikal ya istruktura, ya diad kaunoran et mangiter ed saray artipisyal a graphite negative electrodes na ekselentin konduktibidad, inkapekder na panagbisikleta, tan rate performance, a makasumpal ed saray manunan kakaukolanen na saray baterya na lithium parad "atagey, atagey a kapasidad, andukey a bilay".

3.Saray Manunan Tampok na Produkto

(1) Atagey so Carbon Content tan Abeba so Impurities

Say fixed carbon content Mas baleg o mipara ed 98.5% (high-end power grade specifications Mas baleg o mipara ed 99.5%), ash content Mas abeba odino mipara ed 0.3% (total content na metal impurities a singa say Fe, Ni, Cu Mas abeba o mipara ed 50ppm), sulfur content Mas abeba odino mipara ed 0.1%. nitrogen content ya abeba odino mipara ed 0.2%; Say abeban impurity characteristic et makapaliis ed saray side reactions legan na battery cycling, nabawasan so electrolyte decomposition, tan naseguro so inkapekder na negatibon electrode interface.

(2) Pinaaligwas ya Morpolohiya na Partikulo tan Inkaapag-apag na Kabaleg na Partikulo

Parad Raw Material parad Artificial Graphite Anodes, saray partikulo et malimpek odino ag-regular so kurti ra, walay makinis ya tapew da tan anggapoy matalimbeng iran gilig da (pian ag-onkasil so substrate legan ya man-coating na electrode); say inkaapag-apag na kabaleg na partikulo to et akasentro (D50=10-50μm, Span=0.8-1.2), tan nayarin i-customize unong ed kapal na kakaukolanen na negatibon plato na electrode. Saya so matukoy ed saray proseso na produksyon ya walaan na nanduruman densidad na panag-compact (1.6-1.8g/cm3) pian napaaligwas so inka-consistent na plato na electrode.

(3) Maong ya Graphitization Performance

Baleg so posibilidad ya napaaligwas so grafitization. Kayari na atagey a temperatura na graphitization ed 2800-3000 degree, say graphitization℃et nayarin onabot ed 90%, tan say lattice constant (c0) et abeba odino mipara ed 0.3356nm; Legan na proseso na graphitization, say volume shrinkage rate et mansiansian stable (Makulang odino mipara ed 5%), ya nayarin mamawas ed peligro na pan-crack na saray negatibon produkto na electrode tan mamawas ed saray lugi ed produksyon.

(4) Maong ya Proseso na Pan-adapt

Say pulbos et walaan na ekselentin flowability (anggulo na repose ya kulang o mipara ed 38 degree) tan mainomay ya ilaok ya parepareho ed saray binder (singa say PVDF) pian nawalaan na malet ya sistema na slurry; Legan na proseso na panag-compact, walay mabiskeg ya plasticity to tan ag-itan mainomay ya nabuyak na particle, ya mamaseguro ed saray mekanikal ya kablian na electrode tan onaadapta ed automated coating production lines.

 

 

4. Saray Manunan Lugar na Aplikasyon

(1) Power Lithium Battery Field

Uusaren ed panaggawa na artipisyal ya graphite negative electrodes parad balon energy vehicle power batteries, ya atagey so konduktibidad tan abeban polarization characteristics, saya so mamaaligwas ed battery rate charging tan discharge performance (susuportaan toy 1C-3C fast charging), legan ya naseguro so cycle life na masulok ya 2000 a danay, ya makatulong ed range tan service life na luluganan.

(2) Energy Storage Lithium Battery Field

Matukoy parad lithium battery negative electrodes ed saray energy storage power stations (singa say photovoltaic tan wind power supporting energy storage), say abeban impurity content et makapangibawas ed battery self-discharge rate (monthly self-discharge<=3%), tan say stable graphitization performance et mamaseguro na abeban kapasidad na degradation na battery diad andukey a panaon na karga-siklo na panag-discharge (1000 siklo na degradation Mas abeba odino mipara ed 15%).

(3) Consumer Electronics Lithium Battery Field

No usaren bilang negatibon electrode parad saray lithium batteries ed saray electronic devices a singa saray smartphone tan laptop, say customized particle size distribution et makapangiter na panipis na electrode (say kapal na electrode et abeba odino mipara ed 80μm) tan napaaligwas so densidad na enerhiya na baterya (diad atagey a - kapasidad na positibon electrode, sarag ton nadampot so mas baleg a densidad na enerhiya nen saray o mipara ed electrode anggad 4.5Wh/cm3).

(4) Espisyal ya Lithium Battery Field

No uusaren bilang negatibon electrode parad saray baterya ya lithium diad atagey a temperatura (singa say industrial control equipment) odino abeban temperatura (singa saray kagawaan ed paway), say baterya et mansiansian malet so discharge performance to (capacity retention rate Mas baleg nen o mipara ed 80%) ed -600℃ya karga na karga diad panamegley na regulasyon na imitization℃degree.
