ʻOiai nei, ua hoʻomaka ka hana ʻana o ke kahua mana mālama ikehu pākahiko sodium-ion mua loa o Kina - ʻo Volin sodium-ion battery storage ikehu kikowaena mana ma Nanning, Guangxi. ʻO kēia ka papahana noiʻi a me ka hoʻomohala koʻikoʻi aupuni "100 megawatt-hour sodium-ion battery storage ikehu ʻenehana" o ka pae mua o ka papahana, ʻo ka nui i hoʻokomo ʻia he 2.5 megawatts/10 megawatt-hola.
Ua hoʻopukapuka ʻia a kūkulu ʻia ke kahua mana e ka Guangxi Power Grid Company o Southern Power Grid, a ʻo ka nui o kēia pae he 10 MWh. ʻO ka nui o ka papahana e hiki aku i 100 MWh, hiki ke hoʻopuka i 73 miliona degere o ka uila maʻemaʻe i kēlā me kēia makahiki. Ua hoʻopukapuka ʻia a kūkulu ʻia ke kahua mana e ka Guangxi Power Grid Company o Southern Power Grid, a ʻo ka nui o kēia pae he 10 MWh. ʻO ka nui o ka papahana e hiki aku i 100 MWh, hiki ke hoʻopuka i 73 miliona degere o ka uila maʻemaʻe i kēlā me kēia makahiki, e hōʻemi ana i nā hoʻokuʻu ʻana o ke kalapona dioxide ma 50,000 tone, a e hoʻokō i nā pono uila o 35,000 mau mea hoʻohana hale.
Ke hoʻohālikelike ʻia me ka mālama ʻana i ka ikehu o ka pila lithium-ion, ʻo nā "kaikuaʻana" sodium-ion bateria mālama ikehu maka nā waihona mea maka, maʻalahi ke unuhi, haʻahaʻa ke kumukūʻai, hana maikaʻi ma nā mahana haʻahaʻa, i ka mālama ʻana i ka ikehu nui he mau pono maopopo. "I ka mālama ʻana i ka ikehu o ka pila sodium-ion i ke kahua hoʻomohala, hiki ke hoʻemi ʻia ke kumukūʻai o ke kumukūʻai e 20% a 30%, ma lalo o ke kumumanaʻo o ka hoʻomaikaʻi piha ʻana i ka hoʻonohonoho ʻana a me ke kaʻina hana o ka pila, hoʻomaikaʻi i ka helu hoʻohana o nā mea a me ke ola pōʻaiapuni, hiki ke ʻimi ʻia ke kumukūʻai o ka uila i 0.2 yuan / kWh, ʻo ia ke paipai i ka hoʻohana waiwai o ke ʻano hou o ka mālama ʻana i kahi kuhikuhi koʻikoʻi o ka ʻenehana," wahi a Chen Man, ka waihona ikehu mana aupuni, hope kākau ʻōlelo nui o ke Komite ʻenehana mālama mana uila aupuni a me ka loea ʻenehana pae hoʻolālā o ka Southern Power Grid.
ʻOiai ke holomua nei ka hana a Kina ma ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ka hoʻohālikelike ʻana, ka hoʻolaha ʻana i ka mākeke a me ka hoʻohana ʻana i nā huahana pila sodium-ion, ʻaʻohe hiʻohiʻona honua no ka hoʻohana ʻana i ka ʻenehana pila sodium-ion i nā kikowaena mana mālama ikehu nui.
I Nowemapa 2022, ua hoʻolaha kūhelu ʻo Guangxi Power Grid Company, me ka South Grid Energy Storage Company, ka Institute of Physics of the Chinese Academy of Sciences, Zhongkehai Sodium Technology Co., Ltd. a me nā ʻāpana ʻē aʻe o ka hui papahana, i ka papahana noiʻi a me ka hoʻomohala koʻikoʻi aupuni ma ke kumuhana "100 megawatt-hour sodium-ion battery energy storage system integration technology and application demonstration" e hoʻoponopono i ka hana. "Ke kālele nei mākou i ka hoʻomākaukau ʻana i ka unahi uila hana kiʻekiʻe, ka hoʻohui ʻōnaehana a me ka pale ʻana a me ka kaohi palekana a me nā ʻenehana koʻikoʻi ʻē aʻe e hoʻokō i ka noiʻi, i hoʻokumu ʻia me nā kuleana waiwai kūʻokoʻa o ka hoʻomākaukau ʻana i ka pākaukau sodium-ion a me ka ʻenehana hoʻohui ʻōnaehana," i hoʻolauna ʻia e ke alakaʻi papahana, ʻo ka South China Grid Guangxi Grid Company, ka hope luna hoʻokele o ka 'Oihana Innovation ʻo Gao Lik.
ʻO ke kelepona pākahiko kiʻekiʻe ka ʻāpana kumu o ka ʻōnaehana mālama ikehu pākahiko sodium-ion holoʻokoʻa. Ma hope o hoʻokahi makahiki a me ka hapa o ka noiʻi, ua hoʻomohala ka hui papahana i ka pākahiko mālama ikehu sodium-ion 210Ah lōʻihi mua o ka honua, kahi mahana ākea, palekana kiʻekiʻe. "Mai ka manaʻo o ka hana, loaʻa i kā mākou ʻano pākahiko sodium-ion nā pono o ka wahi mahana hana ākea, ka hoʻouka wikiwiki a me ka lehulehu maikaʻi, a hiki ke hoʻouka ʻia a hiki i 90% i loko o 12 mau minuke," wahi a Hu Yongsheng, he mea noiʻi ma ka Institute of Physics, Chinese Academy of Sciences.
Ma ke ʻano he poʻe loea nui i ka papahana, ʻo ka SouthGrid Energy Storage Company Energy Storage Research Institute i ka hoʻohui ʻana o ka ʻōnaehana mālama ikehu pākahi lithium a me ka pale ʻana a me ka kaohi palekana ma ke kahua he nui ka ʻike noiʻi, e hana ana i ka papahana noiʻi koʻikoʻi aupuni a me ka hoʻomohala ʻana "litium-ion battery energy storage system life cycle application of safety technology". "ʻOiai ua like nā loina o ka hopena o nā pākahi sodium a me lithium, ʻo ka hoʻomohala ʻana i kahi ʻōnaehana mālama ikehu piha e hoʻohui i nā ʻano hoʻouka a me ka hoʻokuʻu ʻana o nā pākahi sodium e pono ai ke lanakila i nā pilikia hou he nui," wahi a Li Yongqi, he loea loea mai SouthGrid Energy Storage Company, me ka manaʻo.
Ma ka lawe ʻana i ka hoʻohui ʻōnaehana ma ke ʻano he laʻana, ua hoʻohana hou ka hui papahana i kahi hoʻolālā mālama ikehu i hoʻolaha ʻia e pili ana i ke ana kiʻekiʻe o nā pila sodium-ion, a hoʻohui ka ʻōnaehana holoʻokoʻa i 88 mau mea hoʻololi modular, e hoʻokō ana i kahi "pili hoʻokahi-a-hoʻokahi" me nā hui pila, ʻoiai ʻo ke ʻano hoʻolaha kuʻuna o ka ʻōnaehana mālama ikehu lithium-ion e pono wale nō e hoʻohui i nā mea hoʻololi he 40 a ʻoi aku. ʻO ke kumu koke o ka pāpālua ʻana i ka helu o nā mea hoʻololi, ʻo ia ka hoʻonui ʻana i ka loaʻa o ka mana a me ka pono o ka hoʻololi ʻana i ka ikehu. ʻOi aku ka pono o ka hoʻololi ikehu holoʻokoʻa o kēia ʻōnaehana mālama ikehu pila sodium ma mua o 92%, ʻoiai ʻoi aku ka liʻiliʻi o nā pila lithium ma mua o 90%, kahi i manaʻo ʻia e hoʻopiha a pani pono i nā pila lithium, a e hoʻopili ʻia i ka mālama ikehu electrochemical nui, nā kaʻa uila, nā mīkini kūkulu a me nā ʻoihana ʻē aʻe.
No ka pale ʻana a me ka kaohi ʻana i ka palekana, ua hoʻomohala ka hui i kahi hoʻolālā hoʻokele wela no ka ʻōnaehana hoʻoluʻu wai a me kahi hoʻonohonoho piha o nā ʻenehana pale ahi a me ka kaohi no ka ʻōnaehana mālama ikehu pākaukau sodium-ion, e like me ka pale wela pae module a me ke kinai ahi kiʻekiʻe.
Hoʻokele ʻia ka ʻokoʻa o ka mahana ma waena o nā cell pila sodium ma mua o 22,000 ma ka ʻōnaehana holoʻokoʻa i loko o 3 degere Celsius. ʻO ka hoʻohana ʻana i ka hoʻolaha wela a me ka pale pale wela.keʻokeʻo aniani fiber aerogelMa ke ʻano he mea pale wela ma waena o ke kumu uila, ʻo ka manawa hoʻolaha thermal o ka monomer pākahiko mai 30 mau minuke a i 2 mau hola, ua hoʻonui ʻia i 4 mau manawa, e hoʻomaikaʻi nui ana i ka palekana o ka module pākahiko.
Ua hoʻomohala ka hui i ka ʻenehana kinai ahi, hoʻoluʻu, a me ka anti-reignition wai nitrogen, hiki ke kinai i ke ahi pākahiko mua i loko o 5 kekona, e hana i 24 mau hola me ka ʻole o ka hoʻā hou ʻana a me ka pahū ʻana. "ʻO ka ʻenehana mālama ikehu lithium a me ka sodium o kēia manawa e paipai i ka hoʻomaikaʻi ʻana i nā ʻano o kekahi i kekahi, ʻike maopopo kēia pūʻulu o ka noiʻi ʻōnaehana mālama ikehu pākahiko sodium-ion a me ka ʻenehana kinai ahi, hoʻoluʻu, a me ka anti-reignition wai nitrogen ma o ka hoʻohana ʻana i ka ʻōnaehana mālama ikehu pākahiko lithium-ion no ke ola o ka hoʻololi ʻana i ka ʻenehana palekana ma ka lithium, ka hoʻonohonoho ʻana o ka ʻōnaehana mālama ikehu sodium no ka manawa mua ma ka noi ʻenekinia," wahi a LiYongQi.
Ianuali 28, 2024, e ka Chinese Academy of Engineering academician Jiang Jianchun, Chinese Academy of Sciences, Cheng Shijie academician, Zhang Yue academician, ka European Union Academy of Sciences Sun Jinhua academician a me nā loea ʻē aʻe o ke Komite Loiloi o ka China Machinery Industry Federation e pili ana i nā hopena o ka papahana e hana i kahi loiloi o ka loiloi: ʻo ka ʻenehana holoʻokoʻa o ka "10 MWh sodium ion battery storage energy system for electrical storage energy stations" i hoʻomohala ʻia e ka hui papahana ma ka pae alakaʻi honua.
