Hele ka poʻe kipa i nā huahana pākaukau sodium ion mai kahi hui Kina ma ka China International Supply Chain Promotion Expo.I kā mākou hana a me ke ola, hiki ke ʻike ʻia nā pā lithium ma nā wahi āpau.Mai nā kelepona paʻa lima, laptops a me nā mea uila ʻē aʻe i nā kaʻa ikehu hou, hoʻohana ʻia nā pākahi lithium-ion i nā hiʻohiʻona he nui, me ka leo liʻiliʻi, ʻoi aku ka paʻa o ka hana a ʻoi aku ka maikaʻi o ka holo ʻana, e kōkua i ka poʻe e hoʻohana maikaʻi i ka ikehu maʻemaʻe.

I nā makahiki i hala iho nei, ua helu ʻo Kina i waena o ka poʻokela o ka honua i ka noiʻi ʻenehana koʻikoʻi a me ka hoʻomohala ʻana, ka hoʻomākaukau ʻana i nā mea waiwai, ka hana ʻana o ka pākaukau a me ka hoʻohana ʻana i nā pihi sodium ion.

Nui ka pono o ka mālama ʻana

I kēia manawa, e wikiwiki ana ka hoʻomohala ʻana o ka mālama ʻana i ka ikehu electrochemical i hōʻike ʻia e nā pā lithium-ion.Lithium ikehu ion pākaukau he kiʻekiʻe kiʻekiʻe kiko'ī ikehu, kiko'ī mana, hoʻopio a me ka hoʻokuʻu 'ana i ka pono a me ka puka uila, a me ka lōʻihi o ka lawelawe ola, liʻiliʻi iho-hoʻokuʻu, ia mea he ikehu mālama ikehu.Ke hāʻule nei nā kumukūʻai hana, hoʻokomo nui ʻia nā pā lithium-ion i loko o ka mālama ʻana i ka ikehu electrochemical, me ka ulu ikaika.

Wahi a ka Ministry of Industry and Information Technology, i ka makahiki 2022, ua hoʻonui ʻia ka nui o ka mālama ʻana i ka ikehu hou o Kina e 200% i kēlā me kēia makahiki, a ʻoi aku ma mua o 20100 mau papahana megawatt i hoʻopili ʻia i ka pahu, a ʻo ia ka mea e mālama ai i ka ikehu pākaukau lithium no 97% o ka. huina mea hou i hookomoia.

“ʻO ka ʻenehana mālama ʻenehana he loulou koʻikoʻi i ka hoʻokō ʻana a me ka hoʻokō ʻana i ka hoʻololi o ka ikehu hou.Ma lalo o ke kumu o ka hoʻolālā pahuhopu lua-carbon, ke ulu wikiwiki nei ka waihona ikehu hou ma Kina. Ke hōʻike nei ka waihona i kahi kūlana "litium dominant".

Ma waena o ka nui o nā ʻenehana mālama ikehu electrochemical, ua paʻa nā pākahi lithium-ion i kahi kūlana koʻikoʻi i nā mea uila uila a me nā kaʻa ikehu hou, e hana ana i kahi kaulahao ʻoihana piha piha.Akā i ka manawa like, ua hoʻopiʻi ka hopohopo i nā hemahema o nā pā lithium-ion.

ʻO ka liʻiliʻi waiwai kekahi o lākou.Wahi a ka poʻe akamai, ʻaʻole kūlike ka māhele honua o nā kumuwaiwai lithium, me kahi o 70 pakeneka ma ʻAmelika Hema, a he 6 pakeneka wale nō o nā kumuwaiwai lithium o ka honua.

Pehea e hoʻomohala ai i ka ʻenehana haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i hilinaʻi ʻole i nā kumuwaiwai kakaikahi?ʻO ka wikiwiki o ka hoʻomaikaʻi ʻana i nā ʻenehana mālama ikehu hou i hōʻike ʻia e nā pihi sodium-ion ke wikiwiki nei.

E like me nā pākahi lithium-ion, ʻo nā pānaʻi sodium-ion kahi pākaukau lua e hilinaʻi nei i nā ion sodium e neʻe ai ma waena o nā electrodes maikaʻi a maikaʻi ʻole e hoʻopau ai i ka hana a me ka hoʻokuʻu ʻana.Ua ʻōlelo ʻo Li Jianlin, ke kākau ʻōlelo nui o ka Energy Storage Standard Committee o ka Chinese Electrotechnical Society, ma ka honua holoʻokoʻa, ʻoi aku ka nui o ka sodium ma mua o ka lithium a hoʻolaha nui ʻia, a ʻo ke kumu kūʻai o nā pā ion sodium he 30-40% haʻahaʻa ma mua o ka. nā pākahi lithium.I ka manawa like, ʻoi aku ka maikaʻi o ka palekana a me ka hana haʻahaʻa haʻahaʻa o ka pāhana sodium, a me ke ola pōʻai kiʻekiʻe, ka mea e lilo ai ka sodium ion i ala ʻenehana koʻikoʻi e hoʻoponopono i ka ʻeha o "hoʻokahi lithium wale nō".

He maikaʻi ka wā e hiki mai ana ka ʻoihana

Hoʻopili nui ʻo Kina i ka noiʻi a me ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā pihi sodium ion.I ka makahiki 2022, e hoʻokomo ʻo Kina i nā ʻenekona sodium i loko o ka 14th Five-Year Plan for Science and Technology Innovation in the Field of Energy, a kākoʻo i ka ʻenehana ʻokiʻoki a me ka ʻenehana kumu a me nā mea hana o nā pā hao sodium.I Ianuali 2023, ua hoʻopuka pū ka ʻoihana a me nā keʻena ʻeono "e pili ana i ka hoʻomohala ʻana i ke alakaʻi ʻana i ka ʻoihana uila uila", e hoʻoikaika i ka noiʻi ʻenehana ʻenehana hoʻopaʻa ʻana i ka ikehu hou, ʻimi noiʻi ʻoi loa ka lōʻihi o ke ola kiʻekiʻe o ka ʻōnaehana pākaukau palekana, ka nui nui. ʻenehana kī nui e mālama i ka ikehu, e wikiwiki i ka noiʻi ʻana a me ka hoʻomohala ʻana i nā ʻenekini hou e like me ka pākaukau sodium ion.

Ua ʻōlelo ʻo Yu Qingjiao, ke kākau ʻōlelo nui o Zhongguancun New Battery Technology Innovation Alliance, ua kapa ʻia ʻo 2023 ka "makahiki mua o ka hana nui ʻana" o nā pāpaʻi sodium i loko o ka ʻoihana, a ke ulu nei ka mākeke pākaukau sodium o Kina.I ka wā e hiki mai ana, i loko o ʻelua a ʻekolu paha pōʻai o nā kaʻa uila, ka mālama ʻana i ka ikehu home, ka mālama ʻana i ka ikehu ʻenehana a me ka ʻoihana, nā kaʻa ikehu hou a me nā ʻāpana ʻē aʻe, e lilo ka pāpaʻi sodium i mea hoʻohui ikaika i ke ala ʻenehana ʻenehana lithium.

I Ianuali o kēia makahiki, ua hāʻawi ʻo JAC yttrium kaʻa kaʻa ikehu hou o Kina i ke kaʻa pākahi sodium mua loa o ka honua.I ka makahiki 2023, ua hoʻomaka mua ʻia ka hanauna mua o ka sodium ion cell cell.Hiki ke hoʻopaʻa ʻia ke kelepona ma ka lumi wela no 15 mau minuke ma ka lumi wela, a hiki i ka mana ke piʻi aku ma mua o 80%.ʻAʻole wale ka haʻahaʻa o ke kumukūʻai, akā ʻo ke kaulahao ʻoihana hoʻi e kūʻokoʻa a hiki ke kāohi.

I ka hopena o ka makahiki i hala, ua hoʻolaha ka National Energy Administration i kahi papahana hōʻike hoʻokele o ka mālama ʻana i ka ikehu hou.ʻO ʻelua o nā mea hope loa he 56 mau pahu sodium-ion.I ka manaʻo o Wu Hui, ka pelekikena o China Battery Industry Research Institute, ke ulu wikiwiki nei ke kaʻina hana ʻoihana o nā ʻona sodium ion.Ua manaʻo ʻia ma ka makahiki 2030, e piʻi ka noi honua no ka mālama ʻana i ka ikehu ma kahi o 1.5 terawatt hola (Twh), a manaʻo ʻia e loaʻa nā pākaona sodium-ion i kahi mākeke nui." , i ka mālama ʻana i ka ikehu home a me ka mālama ʻana i ka ikehu lawe lima, e hoʻohana nui ʻia nā huahana mālama ikehu holoʻokoʻa i ka uila sodium i kēia mua aku.” Wahi a Wu Hui.

Alanui noi a lōʻihi

I kēia manawa, hoʻokipa ka pākaukau sodium ion mai nā ʻāina like ʻole.Ua hōʻike ʻo Nihon Keizai Shimbun i ka lā ʻo Dekemaba 2022, ua ʻoi aku ka nui o Kina ma mua o 50 pakeneka o ka nui o nā patent i hoʻopaʻa ʻia i ka honua i nā ʻāpana sodium ion, ʻoiai 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 ka wikiwiki ʻana o Kina i nā ʻenehana ʻenehana a me ka hoʻohana nui ʻana i nā ʻāpana sodium ion, ua hoʻokomo pū kekahi mau ʻāina ʻEulopa a me ʻAmelika a me ʻAsia i nā ʻōhua sodium i loko o ka ʻōnaehana hoʻomohala ʻana i ka ikehu.

Ua ʻōlelo ʻo Di Kansheng, ka hope manakia nui o Zhejiang Huzhou Guosheng New Energy Technology Co., LTD., hiki i nā pākahi sodium ion ke aʻo mai ke kaʻina hana hoʻomohala o nā pā lithium, hoʻomohala mai ka huahana a hiki i ka ʻoihana, hoʻemi i nā kumukūʻai, hoʻomaikaʻi i ka hana, a hoʻolaha i nā hiʻohiʻona noi. ma na ano a pau.I ka manawa like, pono e kau ʻia ka palekana ma kahi mua, a pono e pāʻani ʻia nā ʻano hana o ka pākaukau sodium ion.

ʻOiai ʻo ka ʻōlelo hoʻohiki, ʻōlelo ka poʻe loea he lōʻihi loa nā pākaona sodium ion mai ka unahi maoli.

Ua ʻōlelo ʻo Yu Puritan, ʻo ka ulu ʻana o ka ʻenehana sodium i kēia manawa ke kū nei i nā pilikia e like me ka haʻahaʻa haʻahaʻa o ka ikehu, ʻo ka ʻenehana e oʻo, pono e hoʻomaikaʻi ʻia ke kaulahao lako, a ʻaʻole i hiki ke kiʻekiʻe o ke kumu kūʻai haʻahaʻa.Pono ka ʻoihana holoʻokoʻa e kālele i ka ʻenehana paʻakikī paʻakikī no ka hoʻolaha ʻana i ka ʻoihana pākaukau sodium i ka hoʻomohala kaiaola a me ka pae kiʻekiʻe.
