Nō nā tata nei, i whakatūria te teihana hiko rokiroki pūngao pākahiko konutai-ion tuatahi o Haina ki Nanning, Guangxi. Koinei te kaupapa rangahau me te whanaketanga matua o te motu "100 megawatt-haora hangarau rokiroki pūngao pākahiko konutai-ion" i te wāhanga tuatahi o te kaupapa, ko te rahi kua tāutahia he 2.5 megawatts/10 megawatt-haora.
Nā te Kamupene Whatunga Hiko o Guangxi o Southern Power Grid te whakangao me te hanga i te teihana hiko, ā, ko te tauine o tēnei wāhanga he 10 MWh. Ka eke te tauine katoa o te kaupapa ki te 100 MWh, ka taea te whakaputa i te 73 miriona nekehanga o te hiko ma ia tau. Nā te Kamupene Whatunga Hiko o Guangxi o Southern Power Grid te whakangao me te hanga i te tipu hiko, ā, ko te tauine o tēnei wāhanga he 10 MWh. Ka eke te tauine katoa o te kaupapa ki te 100 MWh, ka taea te whakaputa i te 73 miriona nekehanga o te hiko ma ia tau, ka whakaiti i ngā tukunga hauhā waro mā te 50,000 tāne, ā, ka tutuki hoki ngā hiahia hiko o te 35,000 kaiwhakamahi kāinga.
Ki te whakataurite ki te rokiroki pūngao pākahiko lithium-ion, ko ngā "teina" pākahiko konutai-ion he rauemi mata e rahui ana i ngā rauemi mata, he ngāwari ki te tango, he iti te utu, he pai ake te mahi i ngā pāmahana iti, ā, he mārama ngā painga o te rokiroki pūngao nui. "I te wā o te whanaketanga, ka taea te whakaiti i te utu o te rokiroki pūngao pākahiko konutai-ion mā te 20% ki te 30%, i raro i te kaupapa o te whakapai ake i te hanganga me te tukanga pākahiko, te whakapai ake i te tere whakamahinga o ngā rauemi me te roa o te huringa, ka taea te tūhura i te utu hiko ki te 0.2 yuan / kWh, hei whakatairanga i te tono ōhanga o te momo rokiroki hou o te ahunga nui o te hangarau," te kī a Chen Man, te rokiroki pūngao ā-motu, te hēkeretari tuarua o te Komiti Hangarau Rokiroki Mana Hiko ā-Motu me te tohunga hangarau taumata rautaki o te Southern Power Grid.
Ahakoa kei te kaha haere tonu ngā mahi a Haina i roto i te rangahau me te whanaketanga, te whakaputa, te whakapūmautanga, te whakatairanga mākete me te tono o ngā hua pākahiko konutai-ion, kāore he tauira o te ao mō te tono o te hangarau pākahiko konutai-ion ki ngā teihana hiko rokiroki pūngao nui.
I te Whiringa-ā-rangi 2022, i whakarewahia mana e te Kamupene Whatunga Hiko o Guangxi, me te Kamupene Rokiroki Pūngao Whatunga Tonga, te Whare Wānanga Ahupūngao o te Whare Wānanga Pūtaiao Hainamana, te Kamupene Hangarau Sodium Zhongkehai, me ētahi atu wāhanga o te tīma kaupapa, te kaupapa rangahau me te whanaketanga matua ā-motu "100 megawatt-haora hangarau whakauru pūnaha rokiroki pūngao pākahiko konutai-ion me te whakaaturanga tono" rangahau mō te mahi. "E arotahi ana mātou ki te whakarite tauine matua hiko mahi-teitei, te whakauru pūnaha me te aukati me te whakahaere haumaru me ētahi atu hangarau matua hei whakahaere rangahau, i hangaia me ngā mana pupuri hinengaro motuhake o te whakarite pākahiko konutai-ion me te hangarau whakauru pūnaha," te whakaaturanga a te kaiārahi kaupapa, te Kamupene Whatunga Guangxi o te Tonga Haina, te kaiwhakahaere tuarua o te Tari Auaha a Gao Lik.
Ko te pūtau pākahiko kaha-teitei te waeine taketake o te pūnaha rokiroki pūngao pākahiko konutai-ion katoa. Whai muri i te kotahi tau me te hawhe o te rangahau, i whakawhanakehia e te tīma kaupapa te pākahiko rokiroki pūngao konutai-ion 210Ah tuatahi o te ao, he roa te ora, he whānui te rohe pāmahana, he haumaru teitei. "Mai i te tirohanga mahi, ko tā mātou momo pākahiko konutai-ion he painga o te rohe pāmahana mahi whānui, te utu tere me te maha o ngā kaha, ā, ka taea te utu ki te 90% i roto i te 12 meneti," te kī a Hu Yongsheng, he kairangahau i te Institute of Physics, Chinese Academy of Sciences.
Hei ngā kaiuru hangarau matua o te kaupapa, he nui ngā wheako rangahau a te SouthGrid Energy Storage Company Energy Storage Research Institute i roto i te whakaurunga pūnaha rokiroki pūngao pākahiko lithium me te aukati me te whakahaere haumaru i roto i te mara, ā, kei te whakahaere i te kaupapa rangahau me te whanaketanga matua ā-motu "te tono huringa ora o te pūnaha rokiroki pūngao pākahiko lithium-ion mō te hangarau haumaru". "Ahakoa he rite ngā mātāpono tauhohenga o ngā pākahiko konutai me te lithium, ko te whakawhanake i tētahi pūnaha rokiroki pūngao katoa e whakakotahi ana i ngā āhuatanga utu me te tuku o ngā pākahiko konutai me wikitoria i ngā wero hou maha," te kī a Li Yongqi, he tohunga hangarau nō te SouthGrid Energy Storage Company, me te kare ā-roto.
Hei tauira, ka whakamahia e te tīma kaupapa he hoahoa rokiroki pūngao tohatoha e hangai ana ki te ngaohiko teitei o ngā pākahiko konutai-ion, ā, ka whakauruhia e te pūnaha katoa he 88 ngā kaitahuri modular, ka tutuki ai he "taurite kotahi-ki-kotahi" ki ngā tautau pākahiko, ko te hoahoa tohatoha tuku iho o te pūnaha rokiroki pūngao lithium-ion me whakauru noa i te neke atu i te 40 ngā kaitahuri. Ko te kaupapa tonu o te whakaneke rua i te maha o ngā kaitahuri ko te whakanui ake i te wātea o te kaha me te pai o te hurihanga pūngao. Ko te pai o te hurihanga pūngao whānui o tēnei pūnaha rokiroki pūngao pākahiko konutai he neke atu i te 92%, ko ngā pākahiko lithium he iti iho i te 90%, e tumanakohia ana ka whakakapi me te whakakapi pai i ngā pākahiko lithium, ā, ka whakamahia ki te rokiroki pūngao hiko matū nui, ngā waka hiko, ngā mīhini hanga me ētahi atu mara.
Mō te ārai me te whakahaere haumaru, kua whakawhanakehia e te tīma tētahi rautaki whakahaere wera mō te pūnaha whakamatao wai me tētahi huinga katoa o ngā hangarau ārai me te whakahaere ahi mō te pūnaha rokiroki pūngao pākahiko konutai-ion, pērā i te ārai wera taumata-mōwae me te tinei ahi tino whai hua.
Ko te rerekētanga pāmahana i waenga i ngā pūtau pākahiko konutai neke atu i te 22,000 i roto i te pūnaha katoa ka whakahaerehia i roto i te 3 nekehanga Celsius. Ko te whakamahinga o te ārai whakamarara wera me te ārai rere wera.paraikete hauhautanga muka karāheHei rauemi ārai wera i waenga i te matua hiko, ka horapa te wā wera o te monomer pākahiko mai i te 30 meneti ki te 2 hāora, ka roa ake ki te 4 ngā wā, ka nui ake te whakapai ake i te haumaru o te waeine pākahiko.
I whakawhanakehia e te tīma te hangarau tinei ahi, whakamatao, me te ārai-whakakā hauota wai e whai hua ana ki te hauota wai, ka taea te tinei i te ahi pākahiko tuatahi i roto i te 5 hēkona, kia 24 hāora te roa me te kore e mura anō, e pahū rānei. "Ko te hangarau rokiroki pūngao lithium me te konutai o nāianei e whakatairanga ana i te whakapai ake i ngā āhuatanga o tētahi ki tētahi, ko tēnei huinga rangahau pūnaha rokiroki pūngao pākahiko konutai-ion me te hangarau tinei ahi, whakamatao, me te ārai-whakakā hauota wai whai hua e whai hua ana ki te hauota wai mā te whakamahi i te huringa ora o te pūnaha rokiroki pūngao pākahiko lithium-ion o te tono whakawhiti hangarau haumaru i roto i te lithium, te pūnaha rokiroki pūngao konutai mō te wā tuatahi i roto i te tono hangarau," te kī a LiYongQi.
I te 28 o Hānuere, 2024, i arotakehia ngā hua o te kaupapa e te tohunga hangarau Hainamana o Jiang Jianchun, te tohunga pūtaiao Hainamana o te Whare Wānanga Hangarau, te tohunga hangarau Cheng Shijie, te tohunga hangarau Zhang Yue, te tohunga hangarau Sun Jinhua o te Kotahitanga o Europi me ētahi atu tohunga o te Komiti Aromatawai o te Rōpū Ahumahi Mīhini o Haina: ko te hangarau whānui o te "pūnaha rokiroki pūngao pākahiko konutai 10 MWh mō ngā teihana hiko rokiroki pūngao hiko" i whakawhanakehia e te rōpū kaupapa kei te taumata rangatira o te ao.
