Isimo Sesicelo kanye Nokuhlaziywa Kwama-Prospect Ama-Electrode e-Graphite ku-Anode Materials yamabhethri e-Lithium-Ion
1. Isimo Sokusetshenziswa: I-Graphite Ibusa Imakethe Kodwa Ibhekene Nezingcindezi Zokushintsha Kobuchwepheshe
1.1 Isikhundla Esivelele Semakethe
Izinto ze-anode ze-graphite (kufaka phakathi i-graphite yemvelo neyokwenziwa) zihlala ziyizona eziyinhloko kuma-anode ebhethri le-lithium-ion, ezibalelwa ngaphezu kwama-99% okuthunyelwa komhlaba wonke ngo-2024. I-graphite yokwenziwa, enezinzuzo ezifana nokuxinana okuphezulu kompompi, ukusebenza kahle komjikelezo (>imijikelezo engu-1,500), kanye nokusebenza kahle kokuqala okungu-93%, ibusa umkhakha webhethri lamandla ngesabelo semakethe esingaphezu kwama-80%. Njengomkhiqizi omkhulu emhlabeni, iShayina ithole umkhiqizo we-负极材料 (izinto ze-anode) ongamathani ayizigidi ezingu-2.16 ngo-2024, ithola ama-98.5% emakethe yomhlaba wonke, kanye nama-anode e-graphite aqukethe ngaphezu kwama-75% alesi sisamba.
1.2 Izinzuzo Ezibalulekile Zezindleko
Ama-anode e-graphite afinyelele izindleko eziphansi ngokusebenzisa umnotho wesilinganiso, njengoba amanani e-graphite yokwenziwa yasekhaya eShayina ehla esuka ku-RMB 55,000/ton ngo-2022 aya ku-RMB 16,500/ton ngo-2024, ukwehla okungu-21.43%. Lokhu kusebenza kahle kwezindleko kuqinisekisa ukwamukelwa kabanzi emikhakheni ethintekayo ngamanani njengezinto zikagesi zabathengi kanye nokugcinwa kwamandla.
1.3 Izithiyo Zobuchwepheshe Ezisafufusa
Umthamo othize we-Graphite ngokwethiyori unqunyelwe ku-372 mAh/g, usondela ophahleni lwawo lokusebenza futhi ulwela ukuhlangabezana nesidingo "sebanga elide kakhulu" ezimotweni ezintsha zamandla (ama-NEV). Ukuphishekela ukuminyana kwamandla aphezulu kumabhethri wamandla aphezulu kuqhuba ukushintshela ezintweni zesizukulwane esilandelayo ezifana nama-anode asekelwe ku-silicon kanye ne-hard carbon.
2. Amathemba Okusebenzisa: Angeke Athathelwe Indawo Esikhathini Esifushane Kodwa Abhekene Nezingozi Zokufaka Endaweni Yesikhathi Eside
2.1 Isikhathi Esifushane (Iminyaka Engu-3–5): I-Graphite Remains Core
- Ukukhula Kwesidingo Esiqhubekayo: Ukwanda kwama-NEV kanye nezimakethe zokugcina amandla kuzothuthukisa isidingo sezinto ze-anode, njengoba ukuthunyelwa kwe-China kulindeleke ukuthi kufinyelele amathani ayizigidi ezingu-2.41 ngo-2025, kanti ama-anode e-graphite asasebenza ngaphezu kuka-70%.
- Ukuthuthukiswa Kobuchwepheshe Kugcina Ukuncintisana: Ubuchwepheshe bokumboza obunesigaba soketshezi buye bandisa impilo yomjikelezo we-graphite anode ngaphezu kwemijikelezo engu-2,000, kuyilapho imiklamo yesakhiwo enezimbobo ze-3D ivumela ukushaja okusheshayo kwemizuzu eyi-15 kufike kumthamo ongu-80%, okuhlangabezana nezidingo zama-elekthronikhi abathengi kanye namabhethri kagesi asezingeni eliphansi.
- Izinzuzo Zezindleko Zisalokhu Zingaphazanyiswa: Ukuqamba okusha ezinqubweni ze-graphitization (isb., i-graphitization eqhubekayo) kunciphisa kakhulu izindleko, kanti ama-anode asekelwe ku-silicon ahlala ebiza kakhulu ngokuphindwe ka-3-5, okunciphisa ukwamukelwa kwesisindo sesikhathi esifushane.
2.2 Isikhathi Eside (Iminyaka emi-5–10): Ama-Anode Asekelwe ku-Silicon Athola Ukudonsa, Acindezela Isabelo Semakethe se-Graphite
- Ukuthuthuka kwe-Anode Esekelwe ku-Silicon: Intuthuko ekwakhiweni kwe-nanostructured, ukulungiswa kwe-carbon coating, kanye nobuchwepheshe be-pre-lithiation kuthuthukise ukusebenza kahle komjikelezo wokuqala kwaba ngaphezu kuka-85%, kwandise impilo yomjikelezo ngaphezu kwemijikelezo eyi-1,000, futhi kunciphisa izindleko ngo-60% kusukela emazingeni ka-2022 kuya ku-RMB 180/kg. Imakethe yomhlaba wonke ye-anode esekelwe ku-silicon kulindeleke ukuthi ifinyelele ku-RMB 30 billion ngo-2025, kanti ukungena kuzodlula u-10%, futhi kungenzeka kube ngu-25% ngo-2030.
- Izinqubomgomo kanye Nezishoshovu Zemakethe: Ukuthengiswa kwe-NEV emhlabeni wonke kulindeleke ukuthi kufinyelele amayunithi ayizigidi ezingama-60 ngo-2030, kuyilapho umthamo wokugcina amandla uhlelelwe ukukhula kusuka ku-300 GWh ngo-2025 kuya ku-800 GWh ngo-2030. Izidingo eziphezulu zamandla zizosheshisa ukwamukelwa kwama-anode asekelwe ku-silicon.
- Indawo Yokuphumula Ye-Graphite's Niche: Ama-anode e-Graphite angase abuyele emuva kumabhethri kagesi asezingeni eliphansi, isitoreji samandla, kanye ne-electronics yabathengi, lapho isabelo semakethe sigugulwa yizinto ezisekelwe ku-silicon, i-lithium-metal, nezinye izinto ezithuthukisiwe.
2.3 Izingozi Ezingaba Khona Zokufaka I-Sodium-Ion Namabhethri E-Solid-State
- Ukuthengiswa Kwebhethri Le-Sodium-Ion: Uma izindleko ziwela ngaphansi kwe-RMB 0.3/Wh, amabhethri e-sodium-ion angaphazamisa isidingo se-graphite anode, ikakhulukazi ekugcinweni kwamandla.
- Ukuphazamiseka Kwebhethri Eliqinile: Inhlanganisela yama-electrolyte e-solid-state kanye nama-anode e-lithium-metal ingashintsha isimo se-anode, yize ukuthengiswa kusasele iminyaka emi-5-10.
3. Izitayela Zemboni Nezincomo Zamasu
3.1 Iziqondiso Zokuphindaphinda Kobuchwepheshe
- Ama-Graphite Anode: Gxila ekuthuthukiseni ukusebenza kokushaja okusheshayo (isb., ukugqoka kwesigaba soketshezi), ukunciphisa izindleko (isb., ukwenziwa kwe-graphit okuqhubekayo), kanye nokuphila isikhathi eside (isb., izakhiwo ezinezimbobo ze-3D).
- Ama-Anode Asekelwe ku-Silicon: Qapha ukuvuthwa kwenqubo ye-CVD silicon-carbon, ukukhiqizwa kwezimboni kwangaphambi kokuguqulwa, kanye nokusetshenziswa kwe-graphite-silicon composite (isb., izixazululo ze-BTR ze-S+i graphite).
- Ama-Anode Avelayo: Ama-anode e-lithium-metal kanye ne-carbon anezimbobo zamabhethri e-lithium-sulfur angena ezigabeni zokuhlola, kanti amaphrojekthi okubambisana kwezimboni nezemfundo aphindeka kathathu kusukela ngo-2022.
3.2 Izincomo Zesu Lebhizinisi
- Isu Lesikhathi Esifushane: Yakha ama-anode ezinhlelo ze-cathode ezine-nickel ephezulu kanye nezinhlanganisela ze-silicon-carbon ukuze kuthuthukiswe amaphrimiyamu omkhiqizo.
- Isu Lesikhathi Eside: Tshala imali kumalungelo obunikazi ayisisekelo (isb., ukuguqulwa kwe-coating, i-pre-lithiation) kanye nokubambisana okuqinile nabakhiqizi bamabhethri abaphezulu aba-5 emhlabeni wonke ukuze kuqiniswe izikhundla zemakethe.
- Ukunciphisa Ingozi: Hlukanisa ukutshalwa kwezimali kuzo zonke izinhlobo zobuchwepheshe be-graphite, based silicon, kanye ne-lithium-metal ukuze uvikele izingozi zokushintsha; beka phambili abahlinzeki abanekhono eliqinile le-ESG kanye nemikhuba yokukhiqiza eluhlaza.
4. Isiphetho
Ama-electrode e-graphite ahlala ebalulekile kuma-anode ebhethri le-lithium-ion esikhathini esifushane, asekelwe yizindleko zawo eziphansi, ukuzinza, kanye nokuthuthukiswa kobuchwepheshe okuqhubekayo. Kodwa-ke, intuthuko kuma-anode asekelwe ku-silicon kanye nokwanda kwezidingo zobuningi bamandla kuma-NEV kubeka engcupheni yokushintsha isikhathi eside. Izinkampani kumele zilinganisele ukusungula izinto ezintsha, ukulawulwa kwezindleko, kanye nokuqina kochungechunge lokuhlinzeka ngokushintsha kusuka "ekwandiseni isikali" kuya "ekuthuthukisweni kwekhwalithi," ekugcineni kuqhubekisele imboni ekubuneni kwamandla okuphezulu, isikhathi eside sokuphila, kanye nezindleko eziphansi.
