He mea kupanaha ka CATL. Ua hoʻolauna ʻo ia i nā pūnaewele Na-ion (sodium-ion) a me kahi pākaukau e pili ana iā lākou
Haʻaheo ka CATL o Kina i ka hanauna mua o nā pūnaeau sodium-ion a me kahi pākahi prototype i hoʻohana ʻia e lākou. Ke hōʻike nei nā kikowaena noiʻi like ʻole i nā mana mua o nā cell no kekahi mau makahiki, a makemake ʻo CATL e hoʻomaka i kahi kaulahao lako no kā lākou hana ʻana ma 2023. No laila, manaʻo ʻo ia e hoʻomākaukau iā lākou no ka hana nui a lawe mai iā lākou i ka mākeke.
Lithium-ion a me Na-ion mau mea (Na+) ma ka mana CATL
ʻO nā pūnaewele sodium-ion - maopopo - ma kahi o ka lithium, hoʻohana lākou i kekahi lālā o ka hui alkaline, sodium (Na). ʻO ka sodium kekahi o nā mea nui loa i ka ʻōpala o ka honua, loaʻa nō hoʻi i ka wai kai a ʻoi aku ka maʻalahi o ka loaʻa ʻana ma mua o ka lithium. No laila, ʻoi aku ka maʻalahi o nā cell Na-ion i ka hana ʻana.ma ka liʻiliʻi loa i ka wā e pili ana i nā mea maka.
Akā, aia nō ka sodium i kona mau hemahema. Wahi a ka leka CATL, ka ikehu kūikawā o nā mea sodium-ion a hiki i ka 0,16 kWh / kg no laila, ʻaneʻane ka hapalua o nā pūnaewele lithium-ion maikaʻi loa. Eia kekahi, ʻo ka hoʻohana ʻana i ka sodium ʻo ia ka "koi koʻikoʻi" pono e pili i ke ʻano a me ke ʻano o nā cell. ʻO kēia ma muli o ka nui o nā ion sodium, ʻo ia ka 1/3 ʻoi aku ka nui ma mua o nā lithium ions a no laila e hoʻokaʻawale i ka anode - i mea e pale ai i ka pōʻino i ka anode, ua hoʻomohala ʻo CATL i kahi anode "paʻakikī paʻakikī".
He hanauna hou o nā pūnaewele Na-ion CATL ka ikehu ikehu o 0,2 kWh / kg a oi aku paha i manaoia e loaa, e hoʻomaka lākou e hehi i nā kuʻekuʻe wāwae o ka lithium iron phosphate (LiFePO4). Loaʻa i nā pūnaewele ion sodium uku lākou i ka 80 pakeneka i 15 mau minukeHe hopena maikaʻi loa ia - ʻo nā kelepona lithium-ion maikaʻi loa i kūʻai ʻia ma ke kiʻekiʻe o 18 mau minuke, a ma nā laboratories ua hiki ke hōʻemi i kēia waiwai.
Pono ka ʻenehana no ka hana ʻana i nā cell Na-ion me ka ʻenehana i ʻike ʻia no nā cell lithium-ion.No laila, hiki ke hoʻololi i nā laina hana mai ka sodium i ka lithium, nā memo CATL. Pono nā mea hou i ʻoi aku ka maikaʻi o ka hana ma nā haʻahaʻa haʻahaʻa a me nā ʻano wela, ma -20 degere Celsius pono lākou e mālama i ka 90 pakeneka (!) o ko lākou hiki muaEia nō naʻe, ʻo nā pāka LFP ma lalo o kēia mau kūlana he 30 pakeneka wale nō o ko lākou hiki ke hoʻāʻo ʻia ma ka lumi wela.
Ua hōʻike ʻo CATL i kahi pākaukau e pili ana i nā cell Na-ion a ʻaʻole ia e kāpae i ka lawe ʻana i nā hopena hybrid i ka mākeke i ka wā e hiki mai ana. ʻO ka hui pū ʻana o nā pūnaewele Li-ion a me Na-ion i hoʻokahi pūʻulu e ʻae iā ʻoe e hoʻohana i nā hopena ʻelua ma muli o nā kūlana lanakila.
Ka leka hoʻoponopono www.elektrowoz.pl: Ua hōʻike ʻia ka prototype mua o nā pūnaewele Na-ion i hoʻopaʻa ʻia i nā pūʻolo kalepa 18650 e ka French Atomic Energy and Alternative Energy Committee CEA ma 2015 (kumu). He 0,09 kWh / kg ko lākou ikehu.
