Nui ka hiki ke mālama i ka mana a me nā kaʻa!

ʻO ke kumu kūʻai o nā pākahi sodium-ion e manaʻo ʻia e ʻoi aku ma mua o 20% ka liʻiliʻi ma mua o nā pākahi lithium hao phosphate.

Me ke kiʻekiʻe o ka lithium carbonate i koe, ʻo ka ulu ʻana o nā pāpaʻi sodium-ion ua lawe maoli i ka manaʻo nui.

Ma ka lā 29 o Nowemapa, ma ke kaulahao ʻoihana pākaukau sodium-ion a me ka ʻaha kūkā kamaʻilio holomua maʻamau, ua hōʻike nā hui ʻoihana i nā mea kūʻai aku a me nā mea kūʻai aku o nā pāpaʻi sodium-ion.

Ma ka ʻaha kūkā pūnaewele, ua ʻōlelo ʻo Huang Qisen, ka luna hoʻomalu o Ningde Times Research Institute, hiki i nā pākaona sodium-ion ke hoʻokō i nā koi o nā mana me ke ola pākaukau ma lalo o 400 mau kilomita. Eia nō naʻe, ma o ke ʻano o ka puʻupuʻu puʻupuʻu o ka ʻōpū, hiki i nā pāpaona sodium-ion ke hoʻokō i nā koi o nā hoʻolālā me ke ola pākaukau o 500 mau kilomita, a ke manaʻo ʻia hoʻi e uhi ʻia ma kahi o 65% o ka mākeke kaʻa kaʻa uila maʻemaʻe.

Manaʻo ʻo Chen Liquan, ka mea hoʻonaʻauao o ka Chinese Academy of Design, me ka hoʻomaikaʻi ʻana i ke kaulahao kalepa, ka hoʻomaikaʻi ʻana o ka ʻenehana ʻenehana hou a me ka hopena o ka hopena, ʻoi aku ka nui o ka uku o nā pākaona sodium-ion ma mua o 20% ka liʻiliʻi ma mua o nā pākahi lithium hao phosphate.

Ua wānana ʻo Baiscotec ma ka makahiki 2030, e ʻoi aku ka nui o ka mākeke o nā pākahi sodium-ion ma mua o 200 biliona yuan; i ka makahiki 2040, hiki i ka trillion-dollar scale.

Manaʻo ʻia e ʻoi aku ka nui o ka mana o ka lithium iron phosphate ma 2024

ʻO Zhongke Haina kahi ʻoihana nāna i hoʻokuʻu i nā pāpaʻi sodium-ion ma Kina ma mua. Ua hoʻokumu ʻia e kahi hui i alakaʻi ʻia e Chen Liquan, he mea hoʻonaʻauao o ka Chinese Academy of Design, a loaʻa pū kekahi puke ʻenehana hohonu a me ka mākaukau.

Ma hope o ka unuhi ʻana i ka mana hilinaʻi o ka hana mua, pili ka huahana electrode maikaʻi me 130mAh / g, a ʻo ka electrode maikaʻi ʻole e pili ana me 320 mAh / g. Ke hoʻohālikelike ʻia me nā ʻāpana lithium iron phosphate, aia nō kahi wahi kikoʻī

Ma ke ʻano o ka mānoanoa o ka ikehu, ua hoʻohana ʻia ka nui o ka ikehu volumetric o Li Shujun i hōʻailona koʻikoʻi no ka ʻokoʻa. No ka mea ma ke kahua o ka mālama ʻana i ka ikehu, ʻoi aku ka koʻikoʻi o ka ikehu volumetric a ʻoi aku ka maikaʻi.

ʻO ka mānoanoa o ka mana volumetric o ka lithium iron phosphate i kēia manawa e pili ana i 360Wh/L, a ʻo ka pā o ka sodium-ion he 280Wh/L. Ua manaʻo ʻia e hoʻonui i ka 330Wh / L i 2023. I ka makahiki 2024, ʻoi aku ka nui o ka ikehu o nā pā lithium hao phosphate i ka degere o kēia manawa, a ʻoiaʻiʻo nō e hiki ke ʻoi aku i kēia degere i ka wā e hiki mai ana. pae.

Hāʻawi ka wā Ningde i ka ʻike maʻemaʻe o ka mana a me nā pahuhopu ulu. ʻO ka hanauna mua o nā huahana pākaukau sodium-ion i hoʻokuʻu ʻia e CATL ma 2021 he ikehu ka nui ma mua o 160Wh/kg; hiki i ka 200Wh/kg ka nui o ka ikehu o ka lua o ka lua o nā huahana pākaukau sodium-ion.

ʻO ke ola pōʻaiapuni kahi pōmaikaʻi o nā pāpaʻi sodium-ion. ʻO nā pākaʻi sodium-ion ke holo kaʻa i kēia manawa ma kahi o 3000-4000 mau manawa. Ua ʻōlelo ʻo Li Shujun, me ka hana nui ʻana o nā huahana a me nā pākaukau, ka palekana o nā huahana a me nā pila, a me ka hoʻomaikaʻi maikaʻi ʻana o ka ʻike pūnaewele o nā mea haumia. Hiki ke hoʻonui i ka helu o nā pōʻai i 6,000, a laila hoʻonui i ka 8,000 a me 10,000.

Eia naʻe, ua ʻae ʻo Li Shujun ʻaʻole i hui pū ʻia ka piʻi ʻana o ke ola pōʻai me ka piʻi ʻana o ka mānoanoa o ka mana. ʻO ka mea maʻamau, e emi iho ke ola pōʻaiapuni o nā cell me ka mānoanoa o ka ikehu kiʻekiʻe, e like me ka emi ʻana o ka mana o nā cell me ke ola pōʻai kiʻekiʻe.

Loaʻa ka nui o nā mea kūʻai aku i ka wahi mālama ikehu a me nā kaʻa

No ka mea, loaʻa ka ikehu uila paʻakai i nā ʻano o ka hana haʻahaʻa haʻahaʻa, ka hoʻolālā kemika paʻa, a me ka palekana pū kekahi, ʻo ka wahi e mālama ai i ka ikehu e lilo i kahua noi nui ma mua o ka lele ʻana i nā kaʻa a me nā kaʻa.

(1) Ka mālama ʻana i ka ikehu: ʻoi aku ka wikiwiki o ka holomua o ka mana uila sodium ma mua o nā ion lithium

ʻO ka mea maʻamau, ʻo ka wahi e mālama ai i ka ikehu ka mea o ka mākeke trillion e hiki mai ana, a ʻo ka nui o ka hoʻomohala ʻana o nā ion sodium. Wahi a ka wānana o ka Zhongguancun Energy Storage Space Market Modern Technology Partnership, ma lalo o kahi kūlana kuʻuna, ʻo ka nui o ka nui o ka nui o ka nui o ka nui o ka nui o ka hoʻopaʻa ʻana i ka ikehu hou e hiki i 48.5 GW i ka makahiki 2026, me ka nui o ka ulu ʻana o ka makahiki ʻelima o 53.3%. Ma kahi kūlana kūpono, hiki i ka 79.5 GW ka nui o ka hiki ke kau ʻia, me ke kumukūʻai hoʻomohala makahiki o 69.2%.

Wahi a Flavour Liang o ka Zhongguancun Power Storage Industry Innovation Partnership, ʻoi aku ka wikiwiki o ka hoʻohana ʻana i nā pihi sodium-ion i ka wahi mālama mana i ka wā e hiki mai ana ma mua o ka holo ʻana o nā pā lithium-ion i ka wā mua.

Ma ke ʻano o ke kulekele, ua wehe mua ʻia ka waha. I ka hoʻomaka ʻana o 2022, ʻo ka 14th Five-Year New Energy Storage Growth Implementation Plan i hoʻopuka ʻia e ka National Development a me Reform Compensation a me ka National Power Management i hōʻike maopopo ʻia he mea nui ia e hoʻolaha i ka ulu ʻana o nā mea hou, hoʻomohala i nā ʻenehana mālama ikehu e like me nā pā sodium-ion, a me ka hana ʻana i kahi hanauna hou o ka mālama ʻana i ka ikehu kiʻekiʻe. E hoʻokō i nā hōʻike hoʻokele papa o nā ala ʻenehana like ʻole, ka noiʻi noiʻi a me ka hoʻokō ʻana i nā hōʻike hoʻokele o ka hanauna hou o ka mānoanoa kiʻekiʻe kiʻekiʻe o ka ikehu hoʻopaʻa ʻana i nā ʻenehana hou e like me nā pākahi sodium-ion a me nā pākahi lithium-ion solid-state.

He mea koʻikoʻi ka hoʻohana ʻana i nā pākahi sodium-ion.

Manaʻo nui ʻo Huang Qisen o Ningde e pili ana i kona holomua ʻana ma ke kahua o ka mālama ʻana i ka ikehu. Manaʻo ʻo ia he ʻoi aku ka nui o ka ikehu uila paʻakai no ka mālama ʻana i ka ʻōnaehana e hoʻomaʻamaʻa i ka hale, ke manaʻo ʻia ke kumukūʻai o ka mālama ʻana e hele ma mua o 80%, e hoʻohaʻahaʻa hou ʻia ke kumukūʻai, a ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka noi mākeke mau ma lalo o ka mōʻaukala o ke kalapona nonpartisanship.

ʻIke loa, ma muli o nā pōmaikaʻi o ke kumukūʻai a me ka hana haʻahaʻa haʻahaʻa, ua ʻike ʻia ʻo ka mana uila sodium e ʻoi aku ka nui o nā manawa e hoʻohana ʻia ai i ka mākeke lead-acid o 100 biliona yuan, a he wahi nō hoʻi ia i ka mākeke fractional o nā kaʻa a me ka mākeke wahi mālama mana āpau.

2) Kaʻa: Hiki ke uhi ʻia ka hui ʻana o ka lithium paʻakai ma kahi o 65% o ka mākeke.

ʻO ka ʻāpana kaʻa he ʻōlelo aʻoaʻo e hopohopo nui nei ka makahiki o Ningde. Maikaʻi i ka hoʻohana ʻana i nā kaʻa kaʻa, manaʻo ʻo Huang Qisen e hiki i nā pāʻani sodium-ion ke hoʻokō i nā koi o nā hiʻohiʻona me ke ola pākaukau ma lalo o 400 mau kilomita. Hoʻohui pū ʻia me ka hana hou o ka puʻupuʻu ʻiʻo o ka ʻōpū i hana ʻia e Ningde Times, ʻoi aku ka hoʻonui ʻia o ka mana o ka ʻōnaehana pākaukau ma o nā pono hoʻohui o ka lithium a me ka paʻakai. 'Ke manaʻo ʻia nei ka hoʻohana ʻana o nā pāpaʻi sodium-ion e hoʻokomo ʻia i ka pūʻulu o 500 mau kilomita o ke ola pākaukau, no laila e kuhikuhi ʻia e pili ana i ka 65% o ka mākeke, a me nā kūlana noi he ākea maoli.

He poepoe a huinaha ko Zhongke Haina

ʻO ka mea kikoʻī, hiki ke hoʻonui koke ʻia ka pahu cyndrical liʻiliʻi o Zhongke Haina 26700, e hoʻomaka ana me 3Ah, a hiki ke hoʻonui ʻia i ka 3.5-4Ah, a ʻo kona ola ʻana e pili ana me 3000-5000 mau manawa. Hoʻohana nui ʻia ia ma ke kahua o ka mana liʻiliʻi a me kahi wahi mālama mana liʻiliʻi.

ʻO nā kinikini liʻiliʻi liʻiliʻi, ʻo Zhongke Haina's cyndrical tube 32140, hoʻomaka ma kahi o 12Ah, a ma hope e hoʻonui wikiwiki i 15Ah. I ka wā e hiki mai ana, aia nā 46 series cylinders a me 60 collection cylinders, me ka mana hoʻokahi o 30Ah a me 50Ah, a me ke ola lawelawe o 3000-5000 mau manawa.

Ke manaʻoʻiʻo nei ʻo Li Shujun ʻo ka mea paahana a me nā cylinders nui ke ʻano kumu mua o nā cylinders i ka wā e hiki mai ana, a e loaʻa iā lākou ka nui o nā noi. Me ka mana liʻiliʻi a me ka mālama ʻana i ka ikehu liʻiliʻi, ʻo ke kaʻa A00-class, ka mālama ʻana i ka ikehu o ka hale, a me ka mālama ʻana i ka mana pāʻoihana a me nā mea kūʻai aku paha ka mea mua o ka wā e hiki mai ana.

E pili ana i nā ʻāpana pākahi, ʻo Zhongkehaina wahi liʻiliʻi he 27 * 148 series, he maʻalahi loa a hoʻohana nui ʻia no ka mālama liʻiliʻi, me ka mana hoʻomaka. ʻOi aku ka maikaʻi o nā mea 60 * 160 no ka mana hoʻihoʻi i loko o ka lumi mālama mana ʻohana, ka pāʻoihana a me ka mālama mana ʻoihana, a me nā wahi pili pū kekahi.

ʻO ka pākaukau pāhaʻi nui, ʻo kekahi o ka mea maʻamau ʻo 72 * 173 * 207, hoʻohana maʻamau ʻia ka pākaukau lithium hao phosphate i ka wahi mālama mana uila. Hiki ke hoʻomaka nā pāpaʻi sodium-ion mai 240Ah, a laila e hoʻonui i ka 280Ah a i ʻole 300Ah, me ke ola pōʻai o 5,000-8,000 mau manawa, a e hoʻonui ʻia i ka nui ma mua o 10,000 mau manawa i ka wā e hiki mai ana. Hoʻohana maʻamau ia i ka mālama ʻana i ka ikehu uila, nā kaʻa kalepa a me nā kaʻa ʻoihana a me nā wahi ʻē aʻe.

Manaʻo ʻo Li Shujun e pili ana i ke ʻano huahana, e hōʻike ana i nā pākaukau lithium hao phosphate, ʻo ka cylindrical medium/nui-nui a me nā cell square ke kuhikuhi nui.

Kākoʻo nui ʻia nā hoʻolālā aupuni i ka ulu ʻana o nā pihi sodium-ion. I ʻApelila 2021, ua hāʻawi ka National Growth and Reform Compensation a me ka Energy Administration i nā alakaʻi no ka hoʻolaha ʻana i ka hoʻomohala ʻana i ka mālama ʻana i ka ikehu hou, ʻo ia hoʻi nā pāpaʻi sodium-ion, ʻo ia ka pepa mua loa i koʻu lāhui e hoʻomau i ka hoʻomohala ʻana i nā pākaona sodium-ion. I ka hopena, ua hoʻokomo ke aupuni i nā papahana kākoʻo he nui.

ʻO nā ʻoihana pākaukau a me nā ʻoihana waiwai ka makemake nui no ka mākeke pākaukau sodium-ion.

I kēia manawa, ua hana maoli nā ʻoihana pākaukau nui a me nā ʻoihana waiwai i nā hoʻonohonoho i ke kahua o nā ion paʻakai. Ma waho aʻe o Zhongke Haina a me Ningde Times, Zhejiang Nachuang, Zhenhua New Materials, Rongbai, Dangsheng a me Chengdu Baisco a me nā ʻoihana ʻē aʻe he hoʻolālā.

Hiki ke ʻike ʻia ma ka ʻaoʻao o ka ulu ʻana o nā pākahi sodium-ion i hōʻike ʻia e Li Xiang o Chengdu Baisige Technology Co., Ltd., ke manaʻo nei lākou e hiki i ka 2023, ʻoi aku ka nui o ka mākeke o nā pākahi sodium-ion ma mua o 3 biliona yuan; i ka makahiki 2025, ʻoi aku ka nui o ka 50 billion yuan, hiki ke hoʻololi ʻia i nā ʻāpana Lead-acid i hoʻohana ʻia i ka mana hoʻihoʻi kamaʻilio, ka mana hoʻihoʻi ʻike kikowaena, a me nā kaʻa uila; i ka makahiki 2030, ʻoi aku ka nui o ka mākeke ma mua o 200 biliona yuan, a e hoʻololi pū lākou i nā ʻāpana lithium manganese oxide, ʻo ia ka mea mua e hoʻohana ʻia i nā kaʻa haʻahaʻa; ʻO ka ikehu a me kekahi mau noi pākaukau mana, e hoʻololi ana i nā pākahi lithium hao phosphate.
