1. Nā Kūlana ʻenehana: Ka lanakila ʻana i nā Bottlenecks ʻOihana ʻO ke ala i ke kūʻai ʻana i nā ʻakika sodium -ion ua ʻākeʻakeʻa ʻia e ka hoʻokō ʻana-offs i nā mea nui. ʻO nā anodes kalapona paʻakikī, kahi mea koʻikoʻi, i kū i kahi kūʻē kūʻokoʻa ma waena o ka loaʻa ʻana o ka hiki ke hoʻohuli kiʻekiʻe, ka hoʻokō Coulombic mua, a me ka pā kiʻekiʻe. Ke hoʻopau nei kēia pilikia i kēia manawa. Ua hāpai kekahi hui i alakaʻi ʻia e Polofesa Yufeng Zhao ma Shanghai University i kahi hoʻolālā hou "Mass Transfer Enhanced Pre-oxidation". Ma ka hoʻoponopono kinetically i ke kaʻina hoʻoheheʻe oxygen, ua hoʻomaikaʻi maikaʻi lākou i nā ʻāpana kī nui ʻekolu o ke kalapona paʻakikī i ka manawa like, e hōʻailona ana i kahi pae nui i mua. Ma ke ʻano like, ua hoʻokumu kahi hui noiʻi i alakaʻi ʻia e Academician Tianshou Zhao ma ke Kulanui o ʻEpekema Hema a me ʻenehana i kahi moʻolelo kupaianaha. E like me ka mea i paʻi ʻia ma Energy & Environmental Science, ua hana lākou i kahi polyanion{10}}layered oxide heterostructure cathode material. Ua hōʻike ʻia kēia cathode i ka lōʻihi loa, e loaʻa ana ma luna o 100,000 mau pōʻai ma kahi -kiʻekiʻe kiʻekiʻe o 100C oiai e paʻa ana he 72.6% o kona mana-ma mua o ka lōʻihi o ke ola o nā pākahi lithium-iona pāʻoihana o kēia manawa a e hōʻike ana i ka hiki i nā polokalamu SIB{19}} lōʻihi ke ola. Ke wikiwiki nei nā hana noiʻi honua. Ua hōʻike nā kānaka ʻepekema ma Brown University i nā ʻike hou e pili ana i ka hana o ka sodium i loko o nā pila, e hāʻawi ana i kahi papa hana hoʻolālā hou no ka hoʻomaikaʻi ʻana i nā mea anode e hoʻomaikaʻi i ke kūpaʻa a me ka nui o ka ikehu. I kēia manawa, ua hoʻomohala ka poʻe noiʻi ma Western University ma Kanada i ka paʻa paʻa -state paʻa sodium me ka hoʻohana ʻana i ka sulfur a me ka chlorine-mea hana, e hoʻonui ana i ka sodium-ion conductivity a me ka palekana.
2. Hoʻonui ʻia: Loaʻa ke ʻano o ka hiki ke hana ʻia ma muli o kēia mau hanana R&D, e piʻi wikiwiki ana ka hana ʻana o nā pāpaʻi sodium{1}}ion. Ua holomua a hoʻomaka ʻo EVE Energy i kāna hana pāʻoihana o kāna -scale sodium{4}}ion pūnaewele mālama ikehu ma kona waihona Jingmen. Hoʻohana ka ʻōnaehana i nā pūnaewele NF155L sodium-iona ma muli o kahi ʻōnaehana NFPP (sodium iron phosphate), e kaena ana i ka palekana kiʻekiʻe, ka laulā wela o ka hana, ka hiki ke kiʻekiʻe, ke ola pōʻaiapuni lōʻihi, a me nā hoʻokuʻu kalapona haʻahaʻa. ʻO ka mea hou aku, ua kau inoa ʻo Guangde Qingna Technology Co., Ltd. i kahi ʻaelike e kūkulu i kahi pāhana hana pākaukau 20 GWh sodium-ion ma Suining, Sichuan. Me ka huina kālā he 6 biliona RMB, e kōkua kēia pāhana iā Suining i ka hoʻololi ʻana mai kahi "lithium-wale nō" i ka hoʻolālā "lithium{16}}sodium dual-drive". ʻOiai ua hoʻokumu ʻia ʻo ia ma ʻAukake 2023, ua hōʻike ʻo Qingna Tech i ka hoʻonui ikaika ʻana, e paʻa ʻole ana i nā kuleana ma ʻeiwa mau hui ma o kāna mau lālā a me ka hoʻopaʻa ʻana ma luna o 100 miliona RMB i kahi pōʻai kālā Pre-A alakaʻi ʻia e Yunhe Fangyuan Capital i Ianuali o kēia makahiki.
3. Ka Pōmaika'i Ko'iko'i: Nā Pōmaika'i Kū'ai Mea Mako Nui Ke ulu nei ka hau'oli e pili ana i nā 'akika sodium -ion i ko lākou mau pono pono'ī. ʻO kahi pōkole ʻenehana hou mai ka International Renewable Energy Agency (IRENA) e hoʻonoho i nā SIB ma ke ʻano he mea hiki ke hoʻololi i nā LIB, hiki ke hōʻemi i ka hilinaʻi ʻana i nā minerala koʻikoʻi a me ka hoʻonui ʻana i ke kūpaʻa o ke kaulahao lako pākaukau honua. Aia ka waiwai nui i ka nui o ka waiwai a me ke kumukūʻai. ʻO 2.74% ka nui o ka lepo, ʻoi aku ka kiʻekiʻe ma mua o ka lithium 0.0065%. Hoʻolaha nui ʻia a maʻalahi hoʻi i ke kumu, e alakaʻi ana i nā kumu kūʻai paʻa a haʻahaʻa. Hōʻike ʻo EVE Energy, ʻoi aku ka haʻahaʻa o ke ola holoʻokoʻa-o kāna mau pūnaewele NF155L ma mua o ka 42% haʻahaʻa ma mua o nā ʻona lithium-ion. Kākoʻo nō hoʻi nā pūnaewele i ka laulā wela o ka hana ʻana mai -40 degere a +60 degere, no laila kūpono lākou i nā hiʻohiʻona mālama ikehu like ʻole. Manaʻo ka poʻe loiloi ʻoihana ma lalo o ka hana nui-nui, hiki ke lilo i 30-40% haʻahaʻa nā kumukūʻai pākaukau sodium{20}}ion ma mua o ko nā ʻokoʻa lithium-ion.
4. Nā Palena Lapaʻau: ʻO ka mālama ʻana i ka ikehu a me ka hoʻokele uila Ke ʻike nui ʻia nei ka palapala ʻāina no nā pāpaʻi sodium{1}}ion, e huli ana i ʻelua mau mākeke kumu: Large -Scale Energy Storage Systems (ESS): Manaʻo ʻia kēia he noi mua. Hōʻike ka poʻe hoʻokō ma EVE Energy i ka maikaʻi o nā SIB i ke kumu kūʻai kumu a me ka loaʻa ʻana o nā kumuwaiwai e kūpono iā lākou no ka -pūnaewele nui a me ka puʻunaue ʻana i ka ikehu. Nā Kaʻa Uila Haʻahaʻa (EV): Loaʻa kēia i nā huila ʻelua/ʻekolu -kaa, kaʻa liʻiliʻi, a me nā kaʻa kaʻa kaʻa haʻahaʻa. Ua hoʻokumu ʻo Qingna Tech i nā hui hoʻolālā me nā alakaʻi ʻoihana e like me Jinpeng Group a me Lima Vehicle Industry, me kahi ʻaelike kūʻai 1.75 GWh / makahiki me Jinpeng. Hāʻawi nā huahana "layered oxide + cylindrical cell" nui o Qingna i ka ikehu a hiki i ka 142 Wh/kg, ke ola pōʻaiapuni ma mua o 6,000 mau pōʻaiapuni, 5C hiki ke hoʻopiʻi/hoʻokuʻu, a ʻoi aku ma mua o 82% ka paʻa ʻana ma -40 degere. Ke hoʻonui nei ka pae honua. Ua hoʻouna ʻo Qingna Tech i nā laʻana a ua hoʻokō i nā manaʻo hui pū ʻana me ʻewalu mau hui ʻEulopa, e ʻimi ana i nā noi ma ka -wikiwiki haʻahaʻa, ka mana hoʻihoʻi noho/UPS, a me nā ʻōnaehana mana hoʻihoʻi aupuni . 5. Future Outlook: Technological Diversification and Industry Synergy. hoʻopili waiwai a pili kaiapuni i ka ʻenehana lithium-ion. E ʻike ka wā e hiki mai ana i ka ʻenehana SIB. Ke ʻimi nei nā ʻoihana e like me Qingna Tech i nā ala hoʻomohala like no nā ʻeke paʻakai paʻa, polyanion, a me -state sodium paʻa. Ke hoʻomau nei nā hui hoʻonaʻauao, e like me ka mea ma Western University, i ka hoʻoponopono ʻana i nā pilikia koʻikoʻi e like me ka neʻe ʻana o ka ion i loko o nā hoʻolālā mokuʻāina paʻa. Ma ka 'ano o ka 'oihana, 'a'ole i mana'o 'ia e ho'ololi loa i nā 'akika lithium-ion. Akā, e puka mai ana kekahi 'āina ho'ohui: hiki ke ho'omau 'ia ka lithium-ion i nā EV hana ki'eki'e, a'o ka sodium-iona e kalai i kona niche i ka ho'opa'a ikehu, nā EV ha'aha'a, a me nā huila 'elua. Panina Me ka holomua ʻana o ka ʻenehana a me nā kaulahao ʻoihana oʻo, ke komo nei nā ʻakika sodium{43}}ion i kahi wā gula o ka hoʻomohala ʻana. ʻO ka piʻi ʻana o kēia kahua ʻaʻole e hoʻololi wale i nā ala ʻenehana mālama ʻana i ka ikehu akā kōkua pū kekahi i ka hoʻohaʻahaʻa ʻana i ke kaomi ʻana i ke kaulahao lako pākaukau lithium-ion, e hoʻokomo i ka ikaika hou i ka hoʻololi ʻana o ka ikehu honua.
