He aha ke kūlana hoʻomohala o ka ʻenehana ʻenehana lithium-ion titanium oxide ma ka home a me ka honua?

Mai ka hoʻomohala ʻana o nā ʻeke lithium-ion i ka makahiki 1991, ʻo ka graphite ka mea nui o ka electrode electrode no nā pā.Lithium titanate, ma ke ʻano he ʻano mea electrode maikaʻi ʻole no nā pā lithium-ion, ua loaʻa ka nānā ʻana i ka hopena o 1990s ma muli o kāna hana maikaʻi loa.No ka laʻana, hiki i nā mea lithium titanate ke mālama i kahi kiʻekiʻe o ka paʻa i ko lākou ʻano aniani i ka wā o ka hoʻokomo ʻana a me ka wehe ʻana i nā ion lithium, me nā hoʻololi liʻiliʻi o nā lattice mau (ka hoʻololi nui.
Hoʻonui nui kēia mea electrode "zero strain" i ke ola pōʻaiapuni o nā pā lithium titanate.Loaʻa i ka Lithium titanate kahi kānana lithium ion diffusion ʻekolu-dimensional me kahi ʻano spinel, nona nā mea maikaʻi e like me nā hiʻohiʻona mana maikaʻi loa a me ka hana wela kiʻekiʻe a haʻahaʻa.Ke hoʻohālikelike ʻia me nā mea electrode kalapona ʻino, ʻoi aku ka kiʻekiʻe o ka lithium titanate (1.55V ʻoi aku ka kiʻekiʻe ma mua o ka lithium metallic), ka mea i hopena i ka papa wai paʻa i ulu pinepine ʻia ma luna o ka ʻili o ka electrolyte a me ka carbon negative electrode ʻaʻole i hoʻokumu ʻia ma ka ʻili o ka lithium titanate. .
ʻO ka mea nui aku, he mea paʻakikī ke hana ʻia nā lithium dendrites ma luna o ka ili o ka lithium titanate i loko o ka pā uila o ka hoʻohana ʻana i ka pākaukau maʻamau.Hoʻopau nui kēia i ka hiki ʻana o nā pōkole pōkole i hana ʻia e nā lithium dendrites i loko o ka pā.No laila, ʻo ka palekana o nā pākahi lithium-ion me ka lithium titanate e like me ka electrode maikaʻi ʻole i kēia manawa ka mea kiʻekiʻe loa ma waena o nā ʻano pākahi lithium-ion a pau i ʻike ʻia e ka mea kākau.
Ua lohe ka hapa nui o ka poʻe i loko o ka ʻoihana i ke ola ʻana o ka pākaukau lithium o ka lithium titanate e hoʻololi ana i ka graphite ʻoiai ʻo ka mea electrode maikaʻi ʻole hiki ke piʻi i ʻumi kaukani mau manawa, ʻoi aku ka kiʻekiʻe ma mua o nā pākahi lithium-ion maʻamau, a e make ia ma hope o kekahi mau tausani mau pōʻai. .
Ma muli o ka nui o ka poʻe loea lithium-ion ʻoihana ʻaʻole i hoʻomaka maoli i ka hana ʻana i nā huahana pākaukau lithium titanate, a i ʻole i hana wale iā lākou i kekahi mau manawa a hoʻopau wikiwiki i ka wā e loaʻa ai nā pilikia.No laila, ʻaʻole hiki iā lākou ke ʻoluʻolu a noʻonoʻo pono i ke kumu e hiki ai i nā pākahi lithium-ion i hana maikaʻi ʻia ke hoʻopau i ke ola o 1000-2000 hoʻoiho a hoʻokuʻu ʻia?

ʻO ke kumu nui o ka pōkole pōkole o ke ola ʻana o nā pākahi lithium-ion kuʻuna ma muli o kekahi o kāna mau mea kumu - ke kaumaha hilahila o ka graphite negative electrode?Ke hoʻololi ʻia ka graphite negative electrode me kahi spinel type lithium titanate negative electrode, hiki ke hoʻokele ʻia ka ʻōnaehana kemika lithium-ion like ʻole he ʻumi kaukani a i ʻole haneli mau haneli.
Eia kekahi, ke kamaʻilio nui ka poʻe e pili ana i ka haʻahaʻa haʻahaʻa haʻahaʻa o nā pā lithium titanate, ʻaʻole lākou e nānā i kahi mea maʻalahi akā koʻikoʻi: ke ola holo lōʻihi loa, palekana kupaianaha, nā hiʻohiʻona mana maikaʻi loa, a me ka hoʻokele waiwai maikaʻi o nā pā lithium titanate.E lilo ana kēia mau hiʻohiʻona i pōhaku kihi koʻikoʻi no ka ʻoihana mālama mālama ikehu lithium-ion nui.
I nā makahiki he ʻumi i hala iho nei, ua ulu nui ka noiʻi ʻana i ka ʻenehana pākaukau lithium titanate ma ka home a me ka honua.Hiki ke hoʻokaʻawale ʻia kāna kaulahao ʻoihana i ka hoʻomākaukau ʻana i nā mea lithium titanate, ka hana ʻana o nā pā lithium titanate, ka hoʻohui ʻana o nā ʻōnaehana pākahi lithium titanate, a me kā lākou noi i ka kaʻa uila a me nā mākeke mālama ikehu.
1. Lithium titanate mea
Ma ke ao holoʻokoʻa, aia nā hui alakaʻi i ka noiʻi a me ka ʻenehana o nā mea lithium titanate, e like me Oti Nanotechnology mai ʻAmelika Hui Pū ʻIa, Ishihara Industries mai Iapana, a me Johnson&Johnson mai United Kingdom.I waena o lākou, ʻo ka mea lithium titanate i hana ʻia e ka titanium ʻAmelika he hana maikaʻi loa ma ke ʻano o ka helu, palekana, ola lōʻihi o ka lawelawe, a me nā mahana kiʻekiʻe a haʻahaʻa.Eia nō naʻe, ma muli o ka lōʻihi loa a me ka pololei o nā ʻano hana hana, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana, e paʻakikī ai ke kālepa a hoʻolaha.
