Ka holomua nui: 500Wh/kg lithium metala pākaukau, hoʻokuʻu ʻia!

I kēia kakahiaka, hoʻolaha ʻo CCTV "Chao Wen Tianxia",he pākahiko lithium metala hoʻokūkū honuaUa wehe ʻia ka laina hana hana ma Hefei.ʻO ka laina hana i hoʻokuʻu ʻia i kēia manawa ua loaʻa i kahi holomua nui i kaka nui o ka ikehu o ka hanauna hou o na paikini metala lithiumo 500Wh/kg.Hoʻomaopopo ʻia ʻo ia ka laina hana mua i hoʻolaʻa ʻia no ka hana ʻana i ka pākaukau lithium metala ma Kina a me ka honua.

Ua ʻōlelo ʻo Professor Zhang Yuegang o ke Kulanui ʻo Tsinghua ma ke kahua me ka hoʻololi ʻana o ka ikehu honua a me ka hoʻonui ʻana, ke hoʻomau nei ka pilikia o ka "manaʻo hopohopo" i nā palena o ka ʻenehana ʻoihana, e koi ana i ka nui o ka ikehu pākaukau e hoʻomau i ka piʻi.Hoʻohana ʻia nā ʻeke metala Lithium i ka lithium metala maʻemaʻee like me ka electrode maikaʻi ʻole, me ka mana kikoʻī kikoʻī kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa loa, ka mea i manaʻo ʻia e hana ʻia nā pākahi metala lithium.ʻoi aʻe ma mua o ka papalua o ka holo ʻana o nā kaʻa uila. He ʻenehana hoʻomohala hou i ka ʻoihana pākaukau o kēia manawa. kuhikuhi hoʻomohala koʻikoʻi.

ʻO ka wehe piha ʻana o ka laina hana ʻenehana lithium metala ma Hefei e hōʻike ana ʻo Kina'O ka nui o ka hā'awi 'ana i ka mana o 500 Wh/kg ki'eki'e o ka ikehu-type mana huahana i alaka'i i ka honua, a 'ike i ka ulu 'ana o ka lithium metala 'ana mai ke kahua ho'okolohua (TRL3) a hiki i ka Breakthrough i ka pae ho'opuka o ka huahana. TRL6-8).I ka wā e hiki mai ana, manaʻo ʻia nā huahana e pāʻani nui i ka mokulele uila, nā kaʻa ikehu hou a me nā ʻoihana ʻē aʻe.ʻO kēia laina hana hoʻolaʻa i hoʻokomo ʻia ma Hefei e hoʻoikaika pū i ka hoʻomaikaʻi ʻana i ka ʻoihana a me ka hoʻomohala ʻana i ke kūlana kiʻekiʻe, e lawe mai ana i nā mea hou aʻe no ka hoʻoulu piha ʻana i nā hiʻohiʻona noi lalo o nā pihi mana ikehu hou.

Wahi a ka ʻike uila, ua ʻike ʻia ka laina hana kūikawā no 500Wh / kg i ka hana ʻana i ka pā uila lithium metala e Anhui Mengwei New Energy Technology Co., Ltd. aia ma Feiqidi Science and Technology City, Economic Development Zone, Hefei City.I ka mahina o Iune i ka makahiki i hala, ua hoʻokō ʻo Anhui Mengwei New Energy Technology Co., Ltd. i kahi holomua nui i ka nui o ka ikehu o kahi hanauna hou o nā pākahi metala lithium o 500Wh/kg.ʻO ka laina hana i hoʻolaʻa ʻia i kēia lā no ka hana ʻana i ka pākaukau lithium metala e hōʻike ana i ka 500Wh/kg lithium metala o ka hui.ua komo i ke kahua o ka hana lehulehu.

Wahi a ka ʻike uila,i Nowemapa 2021, Anhui Mengwei New Energy Technology Co., Ltd. a me Hefei Economic and Technological Development Zone ua kakau inoa i ka aelike hoʻopukapuka no ka papahana mana hou R&D a me ka papahana papahana hana, a me ka papahana mana o ka mana R&D a me ka papahana papahana kumu hanaʻo Mengweixin i hoʻonohonoho ponoʻia ma Hefei.Ma keʻano he meaʻimi i nā pāʻani lithium metala, ka hoʻomakaʻana o ka manapākaukauʻO R&D a me ka papahana kumu hana o Mengweixin system e hōʻailona ana i ka lithium alakaʻi honuae alakaʻi ana nā pā metala i ka hoʻokō ʻana i ka hana nui nui ma Hefei.

ʻO ka hui koʻikoʻi o Mengwei New Energy ka mea i haku ʻia i nā talena ʻepekema a me ka ʻenehana a me nā elite ʻoihana mai nā kulanui kaulana a me nā ʻoihana benchmarking ma ka home a ma waho e like me ke Kulanui ʻo Tsinghua, University of Science and Technology of China, Chinese Academy of Science, etc.Loaʻa i ka hui ka mana o ka ʻenehana ʻenehana lithium metala a me ka hana ʻana i nā huahana nui, a he nui nā ʻenehana alakaʻi hoʻokūkū honua ma nā kahua pili e like me ka lithium battery cathode a me ka anode material design, electrolyte optimization, diaphragm modification, cell manufacturing and intelligent. hana 'akomi. .

He aha ka manaʻo o 500 Wh/kg?Wahi a nā hōʻike, lawe i ka 2019 TeslaʻO ke kumu hoʻohālike S/X ka mana lōʻihi me ka huakaʻi holo lōʻihi loa i kēia manawa ke kūʻai aku nei ma ke ʻano he laʻana, ʻo ka nui o ka ikehu nui o ke kelepona pākaukau i hoʻohana ʻia ma kahi o 243 Wh/kg.ʻO ka nui o ka ikehu o ka pākaukau kokoke i 500 Wh/kg, he mea koʻikoʻi kūpono, ʻo ia hoʻi, hiki iā ia ke ʻaneʻane pālua i ka laulā holo o ka kaʻa uila o kēia manawa..

ʻO nā ʻōhua metala liʻiliʻi he ʻano hou o nā pā me ka lithium metala e like me ka electrode maikaʻi ʻole. ʻIke maʻamau ka ʻoihana e lilo nā ʻenehana paʻa paʻa i ka ʻenehana pākahi o ka hanauna e hiki mai ana, a hiki i nā electrolytes solid-state ke hoʻohana pono i ko lākou kiʻekiʻe ikehu kiʻekiʻe ke hui pū ʻia me nā electrodes ʻino lithium metal.Ua waiho mua ʻo Anhui Mengwei New Energy i ka hoʻolaha ʻana o nā pā hao lithium metala, ua wehe ʻia ka "mile hope" o ka hale hana a me nā noi ʻoihana, a hoʻolālā e hoʻomaka i ka hoʻolaha ʻana o ka ʻenehana paʻa paʻa e hāʻawi i nā mea kiʻekiʻe a me ka māmā. mana no ka electrification o nā mokulele a me nā kaʻa.Ma ke ano o ka palekana, i ka lehulehuʻO ka manaʻo nui loa, ʻo Mengwei New Energy's lithium metala pākahiko he hana maikaʻi loa.Inā paha e paʻakikī ana i nā palena o ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe o ka wela, a i ʻole nā ​​hoʻāʻo palekana e like me ke kui kila kila, ua hōʻea ʻo Mengwei New Energy i ka pae alakaʻi honua.
