Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana ikehu hou, ke ulu nei ka noi no nā pākahi lithium kiʻekiʻe. ʻOiai ʻo nā mea e like me ka lithium iron phosphate (LFP) a me ka lithium ternary e noho ana i kahi kūlana koʻikoʻi, ua kaupalena ʻia ko lākou wahi e hoʻonui ai i ka ikehu, a pono e hoʻomaikaʻi hou ʻia ko lākou palekana. I kēia mau lā, nā pūhui zirconium-based, ʻoi aku ka zirconium tetrachloride (ZrCl₄) a me kāna mau mea i loaʻa, ua lilo i wahi wela no ka noiʻi ʻana ma muli o ko lākou hiki ke hoʻomaikaʻi i ke ola pōʻaiapuni a me ka palekana o nā pā lithium.
ʻO ka hiki a me nā pono o ka zirconium tetrachloride
ʻO ka hoʻohana ʻana o ka zirconium tetrachloride a me kāna mau derivatives i nā pā lithium i hōʻike nui ʻia ma nā ʻano aʻe:
1.Improving ion transfer pono:Ua hōʻike ʻia nā haʻawina e hiki ke hoʻomaikaʻi maikaʻi i ka hoʻololi ʻana o nā ion lithium i nā mea hoʻohui metala metala organik framework (MOF) me nā pae Zr⁴⁺ haʻahaʻa. Hiki i ka pilina ikaika ma waena o nā pūnaewele Zr⁴⁺ a me ka sheath solvation ion lithium i ka neʻe ʻana o nā ion lithium, a laila e hoʻomaikaʻi ai i ka hana wikiwiki a me ke ola pōʻai o ka pā.
2.Enhanced interface paʻa:Hiki i nā derivatives zirconium tetrachloride ke hoʻoponopono i ka ʻōnaehana solvation, hoʻonui i ka paʻa o ka interface ma waena o ka electrode a me ka electrolyte, a hoʻemi i ka hanana ʻana o nā ʻaoʻao ʻaoʻao, a laila e hoʻomaikaʻi ai i ka palekana a me ke ola lawelawe o ka pākaukau.
Ke kaulike ma waena o ke kumu kūʻai a me ka hana: Ke hoʻohālikelike ʻia me kekahi mau kumu kūʻai electrolyte paʻa kiʻekiʻe, ʻoi aku ka haʻahaʻa o ke kumu kūʻai kumu o ka zirconium tetrachloride a me kāna mau derivatives. No ka laʻana, ʻo ke kumukūʻai maka o nā electrolytes paʻa e like me ka lithium zirconium oxychloride (Li1.75ZrCl4.75O0.5) he $11.6/kg wale nō, ʻoi aku ka haʻahaʻa ma mua o nā electrolytes paʻa kuʻuna.
Hoʻohālikelike me ka lithium iron phosphate a me ka lithium ternary
ʻO ka lithium iron phosphate (LFP) a me ka lithium ternary ka mea nui no nā pā lithium i kēia manawa, akā aia kēlā me kēia i kā lākou pono a me nā hemahema. ʻIke ʻia ka Lithium iron phosphate no kona palekana kiʻekiʻe a me ke ola pōʻai lōʻihi, akā haʻahaʻa kona ʻano ikehu; ʻO ka lithium ternary he kiʻekiʻe ka ikehu, akā nāwaliwali kona palekana. ʻO ka ʻokoʻa, hana maikaʻi ka zirconium tetrachloride a me kāna mau derivatives i ka hoʻomaikaʻi ʻana i ka pono o ka hoʻoili ʻana i ka ion a me ka paʻa o ka interface, a ke manaʻo ʻia e hoʻopau i nā hemahema o nā mea i loaʻa.
ʻO nā bottlenecks kālepa a me nā pilikia
ʻOiai ua hōʻike ʻo zirconium tetrachloride i ka mana nui i ka noiʻi ʻana i ke keʻena hana, ke kū nei kāna ʻoihana kūʻai i kekahi mau pilikia:
1. Kaʻina hana oʻo:I kēia manawa, ʻaʻole i oʻo piha ke kaʻina hana o ka zirconium tetrachloride a me kāna mau derivatives, a pono e hōʻoia hou ʻia ke kūpaʻa a me ka kūlike o ka hana nui.
2. Ka hoʻomalu koʻikoʻi:ʻOiai he haʻahaʻa ke kumu kūʻai o nā mea maka, i ka hana maoli, pono e noʻonoʻo ʻia nā kumu kumukūʻai e like me ke kaʻina hana synthesis a me ka hoʻopukapuka lako.
Ka ʻae ʻana o ka mākeke: Lithium iron phosphate a me ternary lithium ua noho mua i kahi māhele mākeke nui. Ma ke ʻano he mea e puka mai ana, pono ka zirconium tetrachloride e hōʻike i nā pono kūpono i ka hana a me ke kumukūʻai e loaʻa ai ka ʻike mākeke.
Manao e hiki mai ana
ʻO Zirconium tetrachloride a me kāna mau mea i loaʻa i nā manaʻo hoʻohana ākea i nā pā lithium. Me ka holomua mau o ka ʻenehana, manaʻo ʻia e hoʻonui ʻia kāna kaʻina hana a e emi mālie ke kumukūʻai. I ka wā e hiki mai ana, manaʻo ʻia ka zirconium tetrachloride e hoʻopiha i nā mea e like me ka lithium iron phosphate a me ka lithium ternary, a hiki i ka hoʻokō ʻana i ka hoʻololi hapa i kekahi mau hiʻohiʻona noi.

Pehea e hoʻomaikaʻi ai ʻo ZrCl₄ i ka hana palekana i nā pila?
1. Kāohi i ka ulu ʻana o ka lithium dendrite
ʻO ka ulu ʻana o nā lithium dendrites kekahi o nā kumu koʻikoʻi no ka pōkole pōkole a me ka holo ʻana o ka wela o nā pā lithium. Hiki i ka Zirconium tetrachloride a me kāna mau derivatives ke kāohi i ka hoʻokumu ʻana a me ka ulu ʻana o nā lithium dendrites ma o ka hoʻoponopono ʻana i nā waiwai o ka electrolyte. No ka laʻana, hiki i kekahi mau mea hoʻohui ZrCl₄ ke hana i kahi papa kuhikuhi paʻa no ka pale ʻana i nā dendrites lithium mai ke komo ʻana i ka electrolyte, a laila e hōʻemi i ka pilikia o ke kaapuni pōkole.
2. Hoʻonui i ka paʻa wela o ka electrolyte
Hiki ke hoʻoheheʻe ʻia nā electrolytes wai maʻamau i nā wela kiʻekiʻe, e hoʻokuʻu ana i ka wela, a laila e holo ka wela.Zirconium tetrachloridea hiki i kāna mau mea hoʻohui ke hui pū me nā mea i loko o ka electrolyte e hoʻomaikaʻi i ka paʻa wela o ka electrolyte. ʻOi aku ka paʻakikī o kēia electrolyte i hoʻomaikaʻi ʻia e decompose i nā wela kiʻekiʻe, ma laila e hōʻemi ai i nā pilikia palekana o ka pākaukau ma lalo o nā kūlana wela kiʻekiʻe.
3. E hoʻomaikaʻi i ka paʻa o ka interface
Hiki i ka Zirconium tetrachloride ke hoʻomaikaʻi i ka paʻa o ka pilina ma waena o ka electrode a me ka electrolyte. Ma ka hana ʻana i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka electrode, hiki iā ia ke hōʻemi i nā ʻaoʻao ʻaoʻao ma waena o ka mea electrode a me ka electrolyte, e hoʻomaikaʻi ai i ka paʻa holoʻokoʻa o ka pā. He mea koʻikoʻi kēia paʻa paʻa i ka pale ʻana i ka hoʻohaʻahaʻa hana a me nā pilikia palekana o ka pākaukau i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana.
4. E ho'ēmi i ka flammability o ka electrolyte
ʻO nā electrolytes wai kuʻuna maʻamau he mea wela loa, e hoʻonui ai i ka pilikia o ke ahi pākaukau ma lalo o nā kūlana hoʻomāinoino. Hiki ke hoʻohana ʻia ʻo Zirconium tetrachloride a me kāna mau derivatives e hoʻomohala i nā electrolytes paʻa a i ʻole semi-solid electrolytes. ʻO kēia mau mea electrolyte maʻamau he haʻahaʻa haʻahaʻa haʻahaʻa, a laila e hōʻemi nui i ka hopena o ke ahi a me ka pahū.
5. E hoʻomaikaʻi i ka hiki ke hoʻokele wela o nā pila
Hiki i ka Zirconium tetrachloride a me kāna mau derivatives ke hoʻomaikaʻi i ka hiki ke hoʻokele wela o nā pā. Ma ka hoʻomaikaʻi ʻana i ka conductivity thermal a me ke kūpaʻa wela o ka electrolyte, hiki i ka pākaukau ke hoʻopau maikaʻi i ka wela i ka wā e holo ai i nā haʻahaʻa kiʻekiʻe, a laila e hōʻemi i ka hiki ke holo i ka wela.
6. Kāohi thermal runaway o nā mea electrode maikaʻi
I kekahi mau hihia, ʻo ka holo wela o nā mea electrode maikaʻi kekahi o nā kumu nui e alakaʻi ai i nā pilikia palekana pālolo. Hiki i ka Zirconium tetrachloride a me kāna mau derivatives ke hōʻemi i ka hopena o ka holo ʻana o ka wela ma o ka hoʻoponopono ʻana i nā waiwai kemika o ka electrolyte a me ka hōʻemi ʻana i ka hopena decomposition o ka mea electrode maikaʻi i nā wela kiʻekiʻe.
