Wehe nā ʻōhua sodium ion i nā ala mālama ikehu hou

Loaʻa nā pākahi Lithium i kā mākou hana a me ke ola.Mai nā mea uila e like me nā kelepona paʻalima a me nā kamepiula a hiki i nā kaʻa ikehu hou, loaʻa nā pā lithium-ion i nā hiʻohiʻona he nui.Me ko lākou liʻiliʻi liʻiliʻi, ʻoi aku ka paʻa o ka hana, a ʻoi aku ka maikaʻi o ka hana hou ʻana, kōkua lākou i ke kanaka e hoʻohana maikaʻi i ka ikehu maʻemaʻe.
I nā makahiki i hala iho nei, ua komo ʻo Kina i mua o ka honua i ka noiʻi ʻenehana koʻikoʻi a me ka hoʻomohala ʻana, ka hoʻomākaukau ʻana i nā mea waiwai, ka hana pākaukau a me ka hoʻohana ʻana i nā pihi sodium ion.
Pono mālama mālama nui
I kēia manawa, ʻo ka mālama ʻana i ka ikehu electrochemical i hōʻike ʻia e nā pā lithium-ion ke wikiwiki nei i kona hoʻomohala ʻana.Loaʻa i nā pākahi Lithium ion ka ikehu kikoʻī kiʻekiʻe, ka mana kikoʻī, ka maikaʻi o ka hoʻokuʻu ʻana, a me ka uila puka, a he lōʻihi ke ola lawelawe a me ka hoʻokuʻu iho liʻiliʻi, e hoʻolilo iā lākou i ʻenehana mālama ikehu kūpono.Me ka ho'ēmiʻana i nā kumukūʻai hana, ua hoʻokomoʻia nā pākaukau lithium-ion ma kahi nui ma ke kahua o ka mālamaʻana i ka ikehu electrochemical, me ka ulu ikaika.
Wahi a ka ʻikepili mai ka Ministry of Industry and Information Technology, ua hoʻonui ʻia ka mana hou o ka mālama ʻana i ka ikehu hou ma Kina i ka 200% makahiki i ka makahiki 2022. ʻOi aku ma mua o 20 mau haneli megawatt pae papahana i hoʻokō i ka hana pili pūnaewele, me ka pākaukau lithium. ʻO ka hoʻopaʻa ʻana i ka ikehu he 97% o ka nui o ka mana i hoʻokomo ʻia.
"ʻO ka ʻenehana mālama ʻenehana kahi loulou nui i ka hoʻomaʻamaʻa ʻana a me ka hoʻokō ʻana i ka ʻenehana hou.I loko o ka pōʻaiapili o ka hoʻolālā pahu kalapona ʻelua, ua ulu wikiwiki ka mālama ʻana i ka ikehu hou o Kina.ʻO Sun Jinhua, he mea hoʻonaʻauao o ka European Academy of Sciences a he kumu aʻoaʻo ma ke Kulanui o ʻEpekema a me ʻenehana o Kina, i ʻōlelo maopopo loa ʻo ke kūlana o kēia manawa o ka mālama ʻana i ka ikehu hou e hoʻomalu ʻia e "hoʻokahi lithium".
Ma waena o nā ʻenehana mālama ikehu electrochemical, ua loaʻa i nā pā lithium-ion kahi kūlana koʻikoʻi i nā mea uila uila a me nā kaʻa ikehu hou, e hana ana i kahi kaulahao ʻoihana piha.Eia nō naʻe, i ka manawa like, ua hoʻohuli ʻia nā hemahema o nā pā lithium-ion.
ʻO ka liʻiliʻi o nā kumuwaiwai kekahi o lākou.Wahi a ka poʻe akamai, mai kahi hiʻohiʻona honua, ʻaʻole kūlike ka hāʻawi ʻana i nā kumuwaiwai lithium, me kahi o 70% i puʻunaue ʻia ma ʻAmelika Hema, a ʻo nā kumuwaiwai lithium o Kina he 6% o ka nui o ka honua.
Pehea e hoʻomohala ai i ka ʻenehana ʻenehana mālama ʻana i ka ikehu i hilinaʻi ʻole i nā kumu waiwai ʻole a he haʻahaʻa koina?Ke wikiwiki nei ka hoʻonui ʻana o nā ʻenehana mālama ikehu hou e hōʻike ʻia ana e nā pākiki sodium ion.
E like me nā pākahi lithium-ion, ʻo ka sodium ion batteries nā ʻāpana lua e hilinaʻi nei i nā ion sodium e neʻe ma waena o nā electrodes maikaʻi a maikaʻi ʻole e hoʻopau i nā hana hoʻouka a hoʻokuʻu.Ua ʻōlelo ʻo Li Jianlin, Kakauolelo Nui o ka Energy Storage Standards Committee o ka Chinese Electrotechnical Society, ma ka honua holoʻokoʻa, ʻoi aku ka nui o ka sodium i nā mea lithium a ua hoʻolaha nui ʻia.He 30% -40% ka ha'aha'a o ke kumu kū'ai o nā pākiki sodium ion ma mua o nā pā lithium.I ka manawa like, ʻoi aku ka maikaʻi o ka palekana a me ka hana haʻahaʻa haʻahaʻa o nā pāpaona sodium, a me ke ola pōʻai lōʻihi, e hana ana iā lākou i ala ʻenehana koʻikoʻi e hoʻoponopono ai i ka ʻeha o ka "hoʻokahi lithium i mana".
ʻO nā kūlana ʻoihana maikaʻi
Hoʻopili koʻikoʻi ʻo Kina i ka noiʻi a me ka hoʻohana ʻana i nā pihi sodium ion.I ka makahiki 2022, e hoʻokomo ʻo Kina i nā ʻenekia sodium i loko o ka 14th Five Year Plan for Science and Technology Innovation in the Energy Field, e kākoʻo ana i ka noiʻi a me ka hoʻomohala ʻana i nā ʻenehana ʻokiʻoki a me nā lako ʻenehana koʻikoʻi no nā pā hao sodium.I Ianuali 2023, ua hoʻopuka pū ka Ministry of Industry and Information Technology a me nā keʻena ʻeono i nā manaʻo alakaʻi no ka hoʻolaha ʻana i ka hoʻomohala ʻana o ka Energy Electronics Industry, e wehewehe ana i ka hoʻoikaika ʻana o nā ʻenehana ʻenehana i ka hana ʻana o nā pākaukau mālama ikehu hou. ʻenehana e like me ka ultra long life and high safety battery system, large-scale, large capacity, and efficient energy storage, a me ka wikiwiki i ka noiʻi ʻana a me ka hoʻomohala ʻana i nā ʻano ʻano pākaukau hou e like me nā ʻona sodium ion.
Ua ʻōlelo ʻo Yu Qingjiao, Kakauolelo Nui o ka Zhongguancun New Battery Technology Innovation Alliance, ua ʻike ʻia ʻo 2023 ʻo ka "makahiki mua o ka hana nui ʻana" o nā pākahi sodium i loko o ka ʻoihana, a ke ulu nei ka mākeke pākī sodium Kina.I ka wā e hiki mai ana, e lilo nā pāpaona sodium i mea hoʻohui ikaika i ka ʻenehana pākahi lithium ma nā ʻāpana he nui e like me ʻelua a ʻekolu paha kaʻa uila huila, mālama ʻana i ka ikehu hale, mālama ʻenehana a me nā ʻoihana, a me nā kaʻa ikehu hou.
I Ianuali o kēia makahiki, ua hāʻawi ʻo Jianghuai Yttrium kaʻa kaʻa ikehu hou o Kina i ka kaʻa pākahi sodium mua loa o ka honua.I ka makahiki 2023, ua hoʻokuʻu ʻia a pae ʻia ka hanauna mua o ka sodium ion battery cell o CATL.Hiki ke hoʻopaʻa ʻia ke kelepona pākaukau ma ka lumi wela no 15 mau minuke, me ka mana o ka pākaukau ma luna o 80%.ʻAʻole wale ka haʻahaʻa o ke kumukūʻai, akā e hoʻokō pū ka kaulahao ʻoihana i ka hoʻopiʻi kūʻokoʻa a hiki ke kāohi.
I ka hopena o ka makahiki i hala, ua hoʻolaha ka National Energy Administration i ka papahana hōʻike hoʻokele o ka mālama ʻana i ka ikehu hou.Ma waena o nā papahana 56 i koho ʻia, aia ʻelua mau papahana pākaukau sodium ion.I ka manaʻo o Wu Hui, ka Pelekikena o ka China Battery Industry Research Institute, ke ulu wikiwiki nei ke kaʻina hana ʻoihana o nā pā uila sodium.E like me ka helu ʻana, ma 2030, e piʻi ka noi honua no ka mālama ʻana i ka ikehu ma kahi o 1.5 terawatt hola (TWh), a manaʻo ʻia nā pākaona sodium ion e loaʻa i kahi mākeke nui."Mai ka mālama ʻana i ka ikehu pae kiʻekiʻe a hiki i ka mālama ʻana i ka ikehu ʻoihana a me ka ʻoihana, a laila i ka mālama ʻana i ka ikehu hale a me ka lawe lima, e hoʻohana nui ka huahana mālama ikehu holoʻokoʻa i ka uila sodium i ka wā e hiki mai ana," wahi a Wu Hui.
Ala noi lōʻihi
I kēia manawa, ke loaʻa nei ka manaʻo o nā pākaona sodium ion mai nā ʻāina like ʻole.ʻO ka Nihon Keizai Shimbun i hōʻike mua ʻia ma ka lā ʻo Dekemaba 2022, ua ʻoi aku ka nui o nā patent a Kina ma ke kahua o nā pāpaona sodium ion ma mua o 50% o ka nui o nā patent pono o ka honua, a ʻo Iapana, ʻAmelika Hui Pū ʻIa, South Korea a me Palani i ka lua a i ka lima.Ua ʻōlelo ʻo Sun Jinhua, ma waho aʻe o Kina e wikiwiki ana i ka holomua a me ka hoʻohana nui ʻana o ka ʻenehana ʻenehana sodium ion, ua hoʻokomo pū nā ʻāina he nui o ʻEulopa, ʻAmelika a me ʻAsia i nā pā hao sodium i loko o ka ʻōnaehana hoʻomohala ʻana i nā pihi mālama ikehu.
