Te Tūnga o te Whakamahinga me te Tātaritanga o te Tirohanga o ngā Irahiko Karāpiti i roto i ngā Rauemi Anode mō ngā Pūhiko Lithium-Ion
1. Tūnga Whakamahinga: Ko te Karāpiti te Mana Nui o te Mākete engari e anga atu ana ki ngā Pēhanga Hangarau Whakahou
1.1 Te Tūnga o te Mākete Matua
Ko ngā rauemi anode graphite (tae atu ki te graphite tūturu me te graphite hangai) kei te noho tonu hei mea matua i roto i ngā anode pākahiko lithium-ion, neke atu i te 99% o ngā tukunga o te ao i te tau 2024. Ko te graphite hangai, me ngā painga pēnei i te kiato teitei o te tap, te mahi huringa pai rawa atu (>1,500 huringa), me te 93% o te pai o te tīmatanga, e whakahaere ana i te rāngai pākahiko hiko me te neke atu i te 80% o te wahanga mākete. Hei kaihanga nui rawa atu o te ao, i tutuki i a Haina te putanga rauemi anode (负极材料) o te 2.16 miriona tone i te tau 2024, e hopu ana i te 98.5% o te mākete o te ao, me ngā anode graphite neke atu i te 75% o tēnei tapeke.
1.2 Ngā Painga Utu Nui
Kua iti ngā utu o ngā anode graphite nā roto i ngā ōhanga tauine, ā, kua heke ngā utu graphite hangai ā-rohe i Haina mai i te RMB 55,000/tana i te tau 2022 ki te RMB 16,500/tana i te tau 2024, he hekenga 21.43%. Mā tēnei whai huatanga utu ka whānuitia te whakamahinga i roto i ngā rāngai e aro nui ana ki te utu pēnei i ngā hikohiko kaihoko me te rokiroki pūngao.
1.3 Ngā Ārai Hangarau Hou
Ko te kaha motuhake o te karāpiti he 372 mAh/g anake, e tata ana ki tōna taumata mahi, ā, e uaua ana ki te whakatutuki i te hiahia mō te "whānuitanga tino roa" i roto i ngā waka hiko hou (NEV). Ko te whai i te kiato kaha teitei ake i roto i ngā pākahiko mana kounga teitei kei te akiaki i te nekehanga ki ngā rauemi o te whakatupuranga e whai ake nei pērā i ngā anode waro-mārō me te silicon.
2. Ngā Tūponotanga Tono: Kāore e taea te whakakapi i te wā poto engari kei te aro atu ki ngā mōrearea whakakapinga mō te wā roa
2.1 Wā Poto (3–5 Tau): Ko te Karāpiti tonu te Matua
- Te Tipu Tonu o te Hiahia: Mā te whānui o ngā mākete rokiroki hiko me ngā NEV ka akiaki i te tono mō ngā rauemi anode, me te matapae ka eke ngā tuku mai i Haina ki te 2.41 miriona tana metrika i te tau 2025, me ngā anode karāpeti tonu e neke atu i te 70%.
- Ka Pupuri te Arotau Hangarau i te Whakataetae: Kua roa ake te ora o te huringa anode graphite i ngā hangarau paninga wai ki tua atu i te 2,000 huringa, ā, mā ngā hoahoa hanganga porous 3D ka taea te utu tere 15-meneti ki te 80% o te kaha, e tutuki ai ngā whakaritenga mō ngā hikohiko kaihoko me ngā pākahiko iti te mana.
- Ngā Painga Utu Kāore anō kia Whakahēngia: Mā ngā mahi auaha i roto i ngā tukanga whakakāwhata (hei tauira, te whakakāwhata tonu) ka whakaitihia ake ngā utu, engari ko ngā anode e hangai ana ki te silicon e 3–5 ngā wā ka nui ake te utu, ka whakawhāiti i te whakamahinga papatipu mō te wā poto.
2.2 Wā Roa (5–10 Tau): Ka Piki te Mana o ngā Anode Hanga-Hikorona, ka Pēhia te Wāhanga Mākete o te Graphite
- Ngā Huarahi Hou o te Anode Hanga-Hangai-Silicon: Nā ngā whanaketanga o ngā hoahoa nanostructured, ngā arotautanga paninga waro, me ngā hangarau pre-lithiation kua whakapai ake i te whai huatanga o te huringa tuatahi ki te neke atu i te 85%, kua roa ake te ora o te huringa ki tua atu i te 1,000 huringa, ā, kua whakaitihia ngā utu mā te 60% mai i ngā taumata o te tau 2022 ki te RMB 180/kg. E matapaetia ana ka eke te mākete anode hanga-silicon o te ao ki te RMB 30 piriona i te tau 2025, me te urunga ki runga ake i te 10%, ā, tera pea ka eke ki te 25% i te tau 2030.
- Ngā Ārahi Kaupapahere me te Mākete: E matapaetia ana ka eke ngā hokonga NEV o te ao ki te 60 miriona waeine i te tau 2030, ā, e tipu ana te kaha rokiroki pūngao mai i te 300 GWh i te tau 2025 ki te 800 GWh i te tau 2030. Mā te nui o ngā tono kiato pūngao ka tere ake te whakamahi i ngā anode e hangai ana ki te silicon.
- Te Hokinga Motuhake o te Karāpiti: Tērā pea ka hoki ngā anode karāpiti ki ngā pākahiko iti te mana, te rokiroki pūngao, me ngā hikohiko kaihoko, ka memeha haere te wāhi mākete nā ngā rauemi matatau e hangai ana ki te silicon, te lithium-metal, me ētahi atu rauemi matatau.
2.3 Ngā Mōrearea Whakakapinga Pea: Ngā Pūhiko Konutai-Ion me ngā Pūhiko Āhua-Tokotahi
- Te Hokohoko Pūhiko Konutai-Ion: Mena ka heke ngā utu i raro iho i te RMB 0.3/Wh, ka raru pea te tono mō te anode karāhe, inā koa i roto i te rokiroki pūngao.
- Te Whakararuraru i te Pūhiko Āhua-Toka: Mā te whakakotahitanga o ngā irahiko āhua-totoka me ngā anode lithium-metal ka taea te huri i te ao anode, ahakoa e 5–10 tau te roa o te hokohoko.
3. Ngā Auahatanga Ahumahi me ngā Taunakitanga Rautaki
3.1 Ngā Aronga Whakahoutanga Hangarau
- Ngā Anode Graphite: Arotahi ki te whakarei ake i te mahi utu tere (hei tauira, ngā paninga wai-āhuatanga), te whakaiti i te utu (hei tauira, te whakakāwhata tonu), me te roa o te ora (hei tauira, ngā hanganga pūwero 3D).
- Ngā Anode Hangai-Hiko: Aroturuki i te pakeketanga o te tukanga hiko-waro CVD, te ahumahi i mua i te whakapūtanga, me ngā tono hiato karāti-hiko (hei tauira, ngā otinga karāti S+i a BTR).
- Ngā Anode Hou: Kei te tīmata ngā anode konukōre-litium me ngā anode waro porous mō ngā pākahiko lithium-whanariki ki ngā wāhanga whakamātautau, ā, kua toru ake ngā kaupapa mahi tahi a te ahumahi me te ao mātauranga mai i te tau 2022.
3.2 Ngā Taunakitanga Rautaki a te Kamupene
- Rautaki Wā Poto: Whakawhanakehia ngā anode mō ngā pūnaha cathode nikara-teitei me ngā hiato silicon-waro hei whakarei ake i ngā hua kounga teitei.
- Rautaki Wā Roa: Hokohoko ki ngā mana pateni matua (hei tauira, ngā whakarerekētanga paninga, te whakatōnga i mua i te whakatōnga) me te whakarite hononga mahi tahi me ngā kaihanga pākahiko o runga e 5 o te ao hei whakaū i ngā tūranga mākete.
- Te Whakaiti i te Mōrearea: Whakawhanuitia ngā haumitanga puta noa i ngā hangarau karāpeti, e ahu mai ana i te silicon, me te lithium-metal hei ārai i ngā mōrearea whakakapinga; te whakatairanga i ngā kaiwhakarato he kaha te mahi ESG me ngā mahi hanga matomato.
4. Whakamutunga
He mea nui tonu ngā irahiko karāpiti i roto i ngā anode pākahiko lithium-ion mō te wā poto, nā te iti o te utu, te pumau, me ngā whakatikatika hangarau tonu. Heoi, ko ngā whanaketanga o ngā anode e ahu mai ana i te silicon me te pikinga o ngā tono kiato pūngao i roto i ngā NEV ka puta he mōrearea whakakapinga mō te wā roa. Me whakataurite e ngā kamupene te auahatanga, te whakahaere utu, me te manawanui o te mekameka tuku ki te whakawhiti mai i te "whanuitanga tauine" ki te "whakarei ake i te kounga," ā, i te mutunga ka akiaki i te umanga ki te kiato pūngao teitei ake, te roa ake o te ora, me ngā utu iti iho.
