I tata nei, ko te teihana hiko rokiroki hiko konutai-katote tuatahi o Haina - Volin sodium-ion pākahiko teihana hiko rokiroki hiko i whakauruhia ki Nanning, Guangxi. Koinei te kaupapa rangahau me te whanaketanga matua o te motu "100 megawatt-hour sodium-ion battery energy storage technology" kaupapa whakaaturanga kaupapa o te wahanga tuatahi o te kaupapa, ko te rahi o te 2.5 megawatts/10 megawatt-haora.
Ko te teihana hiko he haumi me te hanga e Guangxi Power Grid Company o Southern Power Grid, a ko te tauine o tenei wahanga he 10 MWh. Ko te katoa o te tauine o te kaupapa ka tae ki te 100 MWh, ka taea te whakaputa i te 73 miriona nga nekehanga o te hiko ma i ia tau, Ka haumihia te tipu hiko ka hangaia e Guangxi Power Grid Company o Southern Power Grid, a ko te tauine o tenei waahanga ko 10 MWh. Ka eke te tapeke o te kaupapa ki te 100 MWh, ka taea te whakaputa i te 73 miriona nga nekehanga o te hiko ma ia tau, me te whakaiti i nga tuku waro hauhaa ki te 50,000 tana, ka tutuki nga hiahia hiko o te 35,000 nga kaiwhakamahi noho.
Ka whakatauritea ki te rokiroki pūngao pūhiko lithium-ion, "teina" konutai-ion pūngao pūngao rokiroki rāhui rauemi mata, ngāwari ki te tango, utu iti, pai ake te mahi i te pāmahana iti, i roto i te rokiroki pūngao nui-tauine kua kitea painga. "Ko te rokiroki pūngao pūhiko konutai i roto i te tauine o te waahanga whanaketanga, ka taea te whakaheke i te utu o te utu e 20% ki te 30%, i raro i te kaupapa o te whakapai ake i te hanganga o te pākahiko me te tukanga, te whakapai ake i te tere o te whakamahi i nga rauemi me te huringa. ora, te utu o te hiko e taea te tūhura ki te 0.2 yuan / kWh, ko te ki te whakatairanga i te tono ōhanga o te momo hou o te rokiroki o te aronga nui o te hangarau, "te rokiroki pūngao mana motu Chen Man, tuarua hēkeretari-Tianara o te National Electric. Ko te Komiti Hangarau Rokiroki Mana me te tohunga hangarau taumata-rautaki o te Matiti Mana Tonga ki te Tonga.
Ahakoa ko te mahi a Haina i roto i te rangahau me te whakawhanaketanga, te whakaputa, te whakarite paerewa, te whakatairanga i te maakete me te tono o nga hua pākahiko konutai-konutai kei te kaha tonu, kaore he tauira o te ao mo te tono hangarau hiko konutai-katote ki nga teihana hiko rokiroki kaha nui. .
I te marama o Noema 2022, ko Guangxi Power Grid Company, i te taha o te South Grid Energy Storage Company, te Institute of Physics of the Chinese Academy of Sciences, Zhongkehai Sodium Technology Co., Ltd. me etahi atu waahanga o te roopu kaupapa, i whakarewa mana i te motu. kaupapa kaupapa rangahau matua me te whanaketanga kaupapa kaupapa-iti "100 megawatt-hour konutai-ion pūhiko pūngao rokiroki pūngao hangarau whakauru hangarau me te whakaaturanga tono" rangahau Whakaritea te mahi. "E arotahi ana matou ki te whakarite i te tauine hiko hiko teitei, te whakauru i te punaha me te aukati me te whakahaere i te haumaru me etahi atu hangarau matua ki te whakahaere rangahau, i hangaia me nga mana hinengaro motuhake o te whakarite pākahiko konutai-ion me te hangarau whakauru punaha," te kaiarahi kaupapa, ko te South China Grid Guangxi Grid Company, te kaiwhakahaere tuarua o te Tari Innovation Gao Lik i whakaurua.
Ko te pūtau pūhiko kaha-nui te waeine taketake o te katoa o te punaha rokiroki pūngao pūhiko konutai-ion. I muri i te kotahi me te hawhe tau o te rangahau, ka whakawhanakehia e te roopu kaupapa te waahi tuatahi o te ao roa-roa, te whanui o te pāmahana, te haumaru teitei 210Ah konutai-ion pūngao rokiroki pūhiko. "Mai i te tirohanga o te mahi, ko ta maatau momo pākahiko konutai-katote nga painga o te rohe pāmahana mahi whanui, te utu tere me te maha pai, a ka taea te utu ki te 90% i roto i te 12 meneti," ko ta Hu Yongsheng, he kairangahau i te Institute of Physics, Chinese Academy of Sciences.
I te mea ko nga kaiuru hangarau matua i roto i te kaupapa, ko te SouthGrid Energy Storage Company Energy Storage Research Institute i roto i te whakaurunga o te punaha rokiroki hiko pākahiko lithium me te aukati haumaru me te whakahaere i roto i te mara he nui nga wheako rangahau, ka whakahaere i te kaupapa rangahau matua me te whanaketanga " lithium-ion pūngao pūngao pūngao rokiroki pūnaha tono huringa ora o te hangarau haumaru”. "Ahakoa he rite nga tikanga tauhohenga o te konutai me te pākahiko lithium, ko te whakawhanaketanga o te punaha rokiroki hiko katoa e whakakotahi ana i nga ahuatanga o te utu me te tuku o nga pākahiko konutai me kaha ki te wikitoria i nga wero hou," ko ta Li Yongqi, he tohunga hangarau mai i te SouthGrid Energy Storage Company. , me te kare-a-roto.
Ko te whakaurunga o te punaha hei tauira, ka mau te roopu kaupapa i tetahi hoahoanga rokiroki hiko toha i runga i te ngaohiko teitei o nga pākahiko konutai-katote, a ka whakauruhia e te punaha katoa nga kaitahuri 88, me te mohio ki te "kotahi-ki-tetahi reta" me te tautau pūhiko, i te hoahoanga tohatoha tuku iho o te pūnaha rokiroki pūngao lithium-ion me whakauru noa atu i te 40 pūtahuri. Ko te kaupapa tonu o te whakarua i te maha o nga kaitahuri ko te whakanui ake i te waatea me te kaha o te hurihanga kaha. Ko te kaha o te hurihanga o te kaha o tenei punaha rokiroki pūngao konutai he nui ake i te 92%, ko nga pākahiko lithium he iti ake i te 90%, e tika ana kia whakakiia me te whakakapi tika i nga pākahiko lithium, ka whakamahia ki te rokiroki hiko hiko hiko nui. nga waka hiko, nga miihini hanga me etahi atu mara.
Mo te aukati me te whakahaere haumaru, kua whakawhanakehia e te roopu he rautaki whakahaere waiariki mo te punaha whakamatao wai me te huinga katoa o te aukati ahi me nga hangarau whakahaere mo te punaha rokiroki hiko pūngao konutai-ion, penei i te arai waiariki taumata-kowae me tinei ahi tino pai.
Ko te rereketanga o te pāmahana i waenga i te neke atu i te 22,000 nga pūtau pākahiko konutai i roto i te punaha katoa ka whakahaerehia i roto i te 3 nga nekehanga Celsius. Ko te whakamahi i te tohanga wera me te arai rerenga waiarikiparaikete airgel muka karaihehei rauemi arai waiariki i waenga i te uho hiko, ka horahia te wa omaoma monomer pākahiko waiariki mai i te 30 meneti ki te 2 haora, ka roa ki te 4 nga wa, ka tino pai ake te haumaru o te waahanga pākahiko.
I whakawhanakehia e te roopu te hauota wai hei whakakore i te ahi, te whakamahana, te hangarau anti-reignition, ka taea te tinei i te ahi pākahiko tuatahi i roto i te 5 hēkona, ki te mahi i nga haora 24 me te kore e mura me te pahū. "Ko te hangarau rokiroki hiko lithium me te konutai o naianei ki te whakatairanga i te whakapai ake o nga ahuatanga o tetahi ki tetahi e kitea ana, ko tenei huinga o te konutai-ion pākahiko te rangahau punaha rokiroki pūngao me te hauota wai whai hua ki te tinei ahi, whakamahana, hangarau anti-reignition na roto i te hiko pākahiko lithium-ion. Ko te punaha rokiroki tono huringa ora o te tono huringa hangarau haumaru i roto i te lithium, te tukutahi punaha rokiroki pūngao konutai mo te wa tuatahi i roto i te tono miihini, "e kii ana a LiYongQi.
Hanuere 28, 2024, e te Hainamana Academy o Engineering Jiang Jianchun academician, Hainamana Academy o Pūtaiao, Cheng Shijie academician, Zhang Yue academician, te Pākehā Union Academy o Sciences Sun Jinhua academician me ētahi atu tohunga o te China Machinery Ahumahi Federation Appraisal Committee i runga i te nga hua o te kaupapa ki te arotake i te arohaehae: ko te hangarau katoa o te "10 MWh konutai katote puunaha rokiroki hiko mo nga teihana hiko rokiroki hiko" i whakawhanakehia e te roopu kaupapa kei te taumata rangatira o te ao.
