Anoodyada Silicon-ka iyo kaarboonku waxay bilaabayaan caqabad dhammaystiran oo ku wajahan anoodyada graphite (oo ay ku jiraan kookaha batroolka ee graphitized) iyadoo la gaaray horumarro tignoolajiyadeed iyo qiimo dhimis. Si kastaba ha ahaatee, "carshiga" anoodyada graphite wuxuu sii ahaanayaa mid deggan muddada gaaban, isagoo wajahaya khatarta ah in la beddelo mustaqbalka fog. Falanqaynta soo socota waxaa laga sameeyay saddex cabbir: tignoolajiyada, kharashka, iyo codsiga suuqa.
I. Cabbirka Tiknoolajiyadda: "Boobka Waxqabadka" ee Silikoon-Kaarboon Anoodes iyo "Boobka Xaddidan" ee Garaafit Anoodes
Faa'iidooyinka Horumarka ee Silicon-Carbon Anodes
- Awoodda Cufnaanta Tamarta: Awoodda gaarka ah ee aragtiyeed ee silicon (4200mAh/g) waxay ka badan tahay toban jeer tan garaafitka (372mAh/g). Anodyada Silicon-ka-kaarboon ee lagu diyaariyey CVD (Khamriga Uumiga Kiimikada) waxay muujinayaan koror 50% ah oo ku yimid cufnaanta tamarta marka la barbar dhigo garaafitka dhaqameed, iyadoo cimriga wareegga uu ka badan yahay 1000 wareeg (tusaale ahaan, tignoolajiyada qalfoofka kaarboon ee Shanghai Xiba waxay hoos u dhigaysaa heerka bararka elektiroonigga ilaa 5%).
- Yaraynta Arrimaha Ballaarinta Mugga: Walxaha silikoonka ee nanoscale oo ay weheliso qalfoofyada kaarboonka ee daloola waxay sameeyaan qaab-dhismeed "neefsasho leh", taasoo si wax ku ool ah u ilaalinaysa cadaadiska ballaarinta silikoonka. Tusaale ahaan, baytariga 4680 ee Tesla, oo adeegsanaya anodes-ka silikoon-kaarboonka ee CVD, wuxuu gaaraa in ka badan 2500 wareeg wuxuuna suurtogaliyaa dallacaad degdeg ah oo 8 daqiiqo ah.
- La-waafajinta Habka La Kordhiyay: Anoodyada Silicon-ka iyo Kaarboon waxaa lagu dari karaa elektaroolaytyada nus-adag, taasoo sii wanaajinaysa badbaadada iyo cufnaanta tamarta. Anoodyada silicon-ka iyo Kaarboon ee Beijing Lier, oo lagu daray elektaroolaytyada adag ee sulfide, waxay gaaraan cufnaanta tamarta oo ka badan 500Wh/kg waxayna wareegaan cimriga 2000 wareeg.
"Saamaynta Saqafka" ee Graphite Anodes
- Xaddidaadaha Waxqabadka: Awoodda gaarka ah ee wax ku oolka ah ee anodes-ka graphite ayaa ku dhawaad gaartay ugu badnaanteeda aragtiyeed (360mAh/g), iyadoo arrimo ay ka mid yihiin iswaafajinta elektrolytka oo liidata iyo awoodda oo libdha sababtoo ah sameynta filimka SEI (Solid Electrolyte Interphase) inta lagu jiro wareegyada dallacaadda/sii deynta bilowga ah.
- Awoodda Wax-ka-beddelka Xaddidan: In kasta oo wax-ka-beddel lagu samayn karo iyadoo la isticmaalayo kaarboon jilicsan, kaarboon adag, ama nanotubes kaarboon ah, haddana ma dhaafi karaan faa'iidooyinka awoodda aragtiyeed ee walxaha ku salaysan silikoon. Tusaale ahaan, kaarboon adag, iyadoo bixinaysa awood gaar ah oo ka sarreysa garaafitka, haddana ma laha goob deggan oo lagu shubo dallacaadda waxayna la kulantaa burbur degdeg ah oo awoodda ah.
II. Cabbirka Kharashka: "Qalooca Dhimista Kharashka" ee Silikoon-Kaarboon Anodes iyo "Faa'iidada Kharashka" ee Garaafit Anedes
Dhimista Kharashyada ee Silikoon-Kaarboon Anodes
- Isku-filnaanshaha Gaaska Silane: Gaaska Silane (SiH₄), oo ah walxo ceeriin ah oo asaasi u ah anodyada silicon-carbon, ayaa hore ugu tiirsanaa soo dejinta (qiimihiisu wuxuu gaarayaa ilaa 2 milyan oo yuan/tan). Tan iyo 2023, shirkadaha hormuudka ka ah waxay gaareen wax soo saarka gudaha iyada oo loo marayo khadadka wax soo saarka ee iskood u dhisan, taasoo hoos u dhigtay kharashyada ilaa 750,000 yuan/tan. Tani waxay qiimaha anodyada silicon-carbon ka dhigtay 1.5 milyan oo yuan/tan ilaa 750,000 yuan/tan, taasoo u dhow 1.5 jibaar qiimaha anodyada graphite (qiyaastii 500,000 yuan/tan).
- Ballaarinta Habraacyada CVD: Qiimaha qalabka CVD ee gudaha ayaa hoos ugu dhacay saddex meelood meel ka mid ah kuwa dibadda laga keeno, iyadoo awoodda hal-mashiinka ah ay saddex laab kor u kacday. Tusaale ahaan, awoodda wax soo saarka CVD ee shirkad hormuud ah ayaa ka korodhay 100 tan/sanadkii ilaa 5000 tan/sanadkii, taasoo hoos u dhigtay kharashka cutubka 40%.
- Dhaqaale ahaan: Haddii qiimaha anode-ka silicon-ka-kaarboon uu hoos ugu dhaco 1.5 jeer kan graphite, kororka kharashka gaadhiga korontada ku shaqeeya ee heerka A00 oo ku qalabaysan baytari 30kWh ah wuxuu noqon doonaa qiyaastii 2000 yuan, halka uu keenayo koror 15% ah oo kala duwan, taasoo bixinaysa kharash-ool ah oo muhiim ah.
"Qiimaha Qotoda" ee Graphite Anodes
- Kharashyada Alaabta Ceeriin ee Yar: Alaabta ceeriin ee graphite anode, sida batroolka coke iyo irbadda coke, waxay muujinayaan isbeddel qiimo oo yar (tusaale ahaan, batroolka coke ee graphitized oo qiimihiisu yahay 1620-3000 yuan/ton).
- Geedi socodka Wax Soo Saarka ee Bislaaday: Habka wax soo saarka ee anodes-ka graphite (burburinta, granulation, kala soocidda, graphitization heerkulka sare) waa mid aad loo habeeyey, taasoo suurtogalinaysa xakamaynta kharashka marka la eego wax soo saarka tirada badan.
- Faa'iidada Kharashka Muddada Gaaban: Codsiyada kaydinta tamarta (xasaasi u ah nolosha wareegga laakiin aan baahi badan u qabin cufnaanta tamarta) iyo suuqyada baabuurta korontada ku shaqeeya ee heerka hoose, anodes-ka graphite waxay leeyihiin faa'iido kharash.
III. Cabbirka Codsiga Suuqa: "Galitaanka Suuqa" ee Silikoon-Kaarboon Anodes iyo "Suuqa Jira" ee Garaafit Anodes
"Wadada Kobaca Sare" ee Silicon-Carbon Anodes
- Baytariyada Korontada: Shirkadaha hormuudka ka ah sida CATL iyo Tesla ayaa hormuud ka ahaa soo saarista batariyada anode-ka silicon-ka ah. Baahida caalamiga ah ee anode-ka silicon-ka ah ayaa la saadaalinayaa inay gaarto 60,000-70,000 tan marka la gaaro 2026, taasoo u dhiganta cabbirka suuqa oo ah 18-21 bilyan oo yuan.
- Qalabka Elektarooniga ah ee Macaamiisha: Anodyada Silicon-ka iyo kaarboonka ayaa dhex galay in ka badan 25% taleefannada casriga ah ee casriga ah (tusaale ahaan, Honor Magic5 Pro), taasoo kordhisay awoodda batteriga 15% halka ay ku dartay dhumucda 0.1mm oo keliya.
- Baytariyada Xaaladda Adag: Anoodyada Silicon-ka iyo Kaarboonka, oo lagu daray elektaroolaytyada adag, waxay matalaan jihada tiknoolajiyadda muddada dheer. Tusaale ahaan, anodes-ka silicon-ka iyo kaarboonka ee Beijing Lier, oo lagu daray electrolytes-ka adag ee sulfide, waxay gaaraan cufnaanta tamarta oo ka badan 500Wh/kg.
"Difaaca Suuqa ee Jira" ee Graphite Anodes
- Saamiga Suuqa: Anodyada garaafiga hadda waxay ka yihiin in ka badan 95% suuqa walxaha anodka baytariga lithium-ion (iyadoo garaafiga macmalka ah uu ka kooban yahay 80%), taasoo ka dhigaysa mid aan macquul ahayn in la beddelo muddada gaaban.
- Adkeysiga Suuqa ee Niche: Kaydinta tamarta (tusaale ahaan, kaydinta la qaybiyey) iyo suuqyada baabuurta korontada ku shaqeeya ee heerka hoose, anodyada garaafitku waxay sii wadaan inay saldhig yeeshaan sababtoo ah faa'iidooyinka kharashka iyo cimriga wareegga oo ka badan 6000 wareeg.
IV. Aragtida Mustaqbalka: Intee in le'eg ayay Graphite Anodes sii haysan karaan "carshigooda"?
- Muddada Gaaban (1-3 Sano): Anodyada garaafitku way sii jiri doonaan, laakiin anodyada silikoon-kaarboonku waxay si dhakhso ah u kordhin doonaan gelitaanka baytariyada korontada ku shaqeeya iyo qalabka elektaroonigga ah ee macaamiisha ee heerka sare ah.
- Muddada Dhexe (3-5 Sano): Haddii qiimaha anode-ka silicon-ka-kaarboon uu la jaanqaado anode-ka graphite (la filayo 2026), cufnaanta tamarta iyo faa'iidooyinka degdegga ah ee dallacaadda ayaa horseedi doona beddel ballaaran oo ku yimaada kaydinta tamarta iyo suuqyada baabuurta korontada ku shaqeeya ee heerka hoose.
- Muddada Dheer (5+ Sano): Anoodyada Silicon-ka-kaarboon, oo lagu daray elektrolytyada adag, waxay noqon karaan xudunta teknoolojiyada baytariga ee jiilka soo socda, taasoo laga yaabo inay meesha ka saarto awoodda anoodyada graphite.
