ʻO kahi hana wili e koi ana i ka nani o ka nanometer-level, ʻaʻole hiki ke hoʻohana i nā lei aniani a i ʻole ka alumina maʻamau. Pono ia i ka zirconia.

ʻO nā pēke Yttria-stabilized zirconia (YSZ) ka media wili seramika hana kiʻekiʻe loa i loaʻa i kēia mau lā. Me ka mānoanoa maoli ma kahi o 6.0 g/cm³, ʻoi aku ka paʻakikī o Vickers ma mua o 1,300 HV, a me ka paʻakikī Mohs o 9, noho lākou ma luna o ka pyramid media wili. ʻAʻole e like me ka zirconium silicate beads (i kapa pinepine ʻia "65 zirconia beads"), e lawelawe ana i nā noi koʻikoʻi koʻikoʻi, yttria-stabilized zirconia beads kahi i hiki ʻole ke hoʻololi i ka maʻemaʻe huahana a pono e hoʻonui ʻia ka pono o ka wili.

Ma hea lākou e hoʻohana ʻia ai?

 

ʻO ka cathode pākahiko Lithium a me nā mea anode - lithium iron phosphate (LFP), nickel manganese cobalt (NMC), a me nā electrolytes solid-state. Nā mea hoʻopaʻa uila - MLCC, nā pahu piezoelectric, nā alumina a me nā panina nitride silika.

ʻEhā mau waiwai i hoʻonohonoho ʻia i ka yttria-stabilized zirconia beads mai nā mea wili ʻē aʻe a pau.

ʻoʻoleʻa loa. Mohs hardness 9, Vickers >1,300 HV. ʻO kēia ka mea paʻakikī iā lākou e like me ka alumina ma ke ʻano o ke kūʻē ʻana, akā me ka ʻoi aku o ka ʻoi aku ka ʻoi aku o ka paʻakikī o ka haʻihaʻi - ma mua o 8 MPa·m¹/².

ʻO ka haku mele a me ka microstructure.Hoʻokumu ʻia nā lei zirconia i hoʻopaʻa ʻia i ka Yttria me ka zirconium oxide (ZrO₂) i hoʻopaʻa ʻia me 3–5% yttrium oxide (Y₂O₃). ʻO ka haku mele maʻamau: ZrO₂ 94.8–95.0%, Y₂O₃ 5.0–5.2%. Hoʻopaʻa ka yttria i ka māhele aniani tetragonal ma ka lumi wela, nona ke kuleana no ka ʻoi loa o ka ʻokiʻoki ʻana o ka mea. ʻO ka microstructure he ʻanoʻano maikaʻi, mānoanoa, a pore-free, me ka nui o ka palaoa ma lalo o 0.5 μm.

Kaʻina hana hana.Hoʻomaka ke kaʻina hana me ka pauka zirconium oxide maʻemaʻe kiʻekiʻe, i hoʻohālikelike pono ʻia me ka yttrium oxide stabilizer. Hoʻopili ʻia ka pauda e loaʻa i ka nui o nā ʻāpana like ʻole, a laila e hoʻomaloʻo ʻia.

He aha ka mea i hoʻokaʻawale iā Tecera.Hāʻawi nā mea hoʻolako he yttria-stabilized zirconia beads akā ʻokoʻa loa ka maikaʻi mai ka pūʻulu a i ka pūʻulu. Hoʻohana ʻo Tecera i ka mana sintering pololei a me ka hoʻokaʻawale ʻana no ka mālama ʻana i ka nui o ka bead i loko o ±0.1 mm, me ka sphericity ma mua o 97% no nā anawaena āpau. ʻO nā ʻili pele i hoʻomaʻamaʻa ʻia hoʻi e hōʻemi i ka ʻaʻahu ʻana i nā mea wili a hiki i ka 30%, e hoʻemi ana i nā kumukūʻai mālama o kāu mea kūʻai aku i ka wā e hoʻolōʻihi ʻia ai ke ola o ka media.

ʻO ka maikaʻi wili like ʻole.No ka mea, he 6.0 g/cm³ - oi aku ka nui o ka yttria-stabilized zirconia ma mua o ka papalua o ka pahu aniani (2.5) a me ka 60% ki'eki'e ma mua o ka alumina (3.6–3.9) - i kēlā me kēia hui 'ana e ho'ololi i ka ikehu kinetic i 'oi aku ka nui o ka ikehu kinetic i nā mea kiko. I loko o ka wili wili kiʻekiʻe, ʻo ia ke ʻano o ka manawa wili hoʻokahi e hana i nā ʻāpana ʻoi aku ka maikaʻi, a i ʻole e loaʻa ka maikaʻi like i ka manawa liʻiliʻi. No ka mea hana lithium battery cathode e hana ana i 10 tons o LFP i kēlā me kēia lā, e ho'ēmi ana i ka manawa pōʻaiapili wili e 30% unuhi pololei i ka hoʻonui ʻana a me ka emi ʻana o ke kumukūʻai ikehu no ka kilo.

Hoʻopau piha i ka hao.No ka mea, ʻaʻohe hao manuahi, ʻaʻohe kumu kila, a ʻaʻohe metala hiki ke hoʻoheheʻe ʻia, komo ka hao ʻole i ke kahawai huahana. I ka hana ʻana i ka pākaukau lithium, hiki i ka 10 ppm o ka hao mai ka media kila ke hoʻoikaika i nā hopena ʻaoʻao e hōʻemi i ka hiki a me ke ola pōʻai.

ʻO nā mea pākaukau Lithium (cathode a me anode).ʻO nā pahu zirconia i hoʻopaʻa ʻia ʻo Yttria ka media maʻamau no ka wili ʻana i nā mea cathode e like me LFP, NMC, a me nā mea hoʻohui conductive e like me ke kalapona ʻeleʻele. ʻO ka wili ʻana i ka nui ʻāpana sub-micron e hoʻomaikaʻi i ka ʻili a me ka nui o ka diffusion lithium ion, e pili pono ana i ka hiki o ka pākaukau a me ke ola pōʻai. Hoʻohana pū ʻia nā peʻa no ka wili ʻana i nā electrolytes solid-state a me nā anodes silika. Ua hōʻike kekahi mea hana pākaukau nui ma Kina, ʻo ka hoʻololi ʻana mai ka alumina a i ka 95% zirconia beads ua hoʻemi ʻia ka hao mai 25 ppm a i lalo o 5 ppm, e hoʻokō ana i nā kikoʻī paʻa o kā lākou mea kūʻai aku a hiki i kahi ʻaelike miliona miliona.
