1.Polution pilikia ma hope o recycling lithium hao phosphate
He nui ka mākeke hoʻololi ʻana i ka pā uila, a e like me nā keʻena noiʻi kūpono, manaʻo ʻia ka nui o ka nui o ka puʻu mana o Kina i ka 137.4MWh e 2025.
Lawe ana ʻo nā ʻanuʻu lithium hao phosphatee like me ka laʻana, ʻelua mau ala no ka hana hou ʻana a me ka hoʻohana ʻana i nā pihi mana hoʻomaha e pili ana: ʻo ka hoʻohana ʻana i ka cascade, a ʻo ka wehe ʻana a me ka hana hou ʻana.
ʻO ka hoʻohana ʻana i ka Cascade e pili ana i ka hoʻohana ʻana i nā pihi mana lithium iron phosphate me ke koena o ka mana ma waena o 30% a 80% ma hope o ka wehe ʻana a me ka hoʻohui hou ʻana, a hoʻopili iā lākou i nā wahi haʻahaʻa haʻahaʻa e like me ka mālama ʻana i ka ikehu.
ʻO ka weheʻana a me ka hana houʻana, e like me ka inoa e hōʻike nei, e pili ana i ka weheʻana i nā pāhana mana lithium iron phosphate i ka emiʻana o ka mana i koe ma mua o 30%, a me ka hoʻihoʻiʻana i kā lākou mau mea maka, e like me ka lithium, phosphorus, a me ka hao i ka electrode maikaʻi.
ʻO ka wehe ʻana a me ka hana hou ʻana o nā pā lithium-ion hiki ke hōʻemi i ka ʻeli ʻana o nā mea maka hou no ka pale ʻana i ke kaiapuni a loaʻa pū kekahi waiwai waiwai nui, e hōʻemi nui ana i nā kumukūʻai mining, nā kumukūʻai hana, nā koina hana, a me nā kumukūʻai hoʻonohonoho laina hana.
ʻO ka manaʻo nui o ka wehe ʻana a me ka hana hou ʻana o ka pā lithium-ion i kēia mau ʻanuʻu: ʻo ka mua, e hōʻiliʻili a hoʻokaʻawale i nā ʻōpala lithium ʻōpala, a laila e hoʻopau i nā pā, a hope e hoʻokaʻawale a hoʻomaʻemaʻe i nā metala.Ma hope o ka hana ʻana, hiki ke hoʻohana ʻia nā metala a me nā mea i hoʻihoʻi ʻia no ka hana ʻana i nā pihi hou a i ʻole nā huahana ʻē aʻe, e mālama nui ana i nā kumukūʻai.
Eia nō naʻe, i kēia manawa me kahi hui o nā hui hoʻoheheʻe pākaukau, e like me Ningde Times Holding Co., Ltd. ʻo Guangdong Bangpu Circular Technology Co., Ltd., ke kū nei nā mea a pau i kahi pilikia ʻoi: .Pono koke ka mākeke i nā ʻenehana hou e hoʻomaikaʻi i ka haumia a me ka ʻawaʻawa o ka recycling pākaukau.
Ua loaʻa iā 2.LBNL nā mea hou e hoʻoponopono ai i nā pilikia haumia ma hope o ka hana hou ʻana i ka pākaukau.
I kēia mau lā, ua hoʻolaha ʻo Lawrence Berkeley National Laboratory (LBNL) ma ʻAmelika Hui Pū ʻIa ua loaʻa iā lākou kahi mea hou e hiki ke hana hou i nā ʻōpala lithium-ion me ka wai wale nō.
Ua hoʻokumu ʻia ʻo Lawrence Berkeley National Laboratory ma 1931 a mālama ʻia e ke Kulanui o Kaleponi no ka US Department of Energy's Science Office.Ua lanakila ʻo ia i nā makana Nobel 16.
ʻO ka mea hou i haku ʻia e Lawrence Berkeley National Laboratory i kapa ʻia ʻo Quick-Release Binder.Hiki ke hoʻohana hou ʻia nā pākahi Lithium-ion i hana ʻia mai kēia mea, pili i ke kaiapuni, a ʻaʻohe mea ʻawaʻawa.Pono lākou e hoʻokaʻawale a hoʻokomo i loko o ka wai alkaline, a hoʻoluliluli mālie e hoʻokaʻawale i nā mea pono.A laila, kānana ʻia nā metala mai ka wai a maloʻo.
Ke hoʻohālikelike ʻia me ka hana hou ʻana o ka lithium-ion i kēia manawa, e pili ana i ka ʻoki ʻana a me ka wili ʻana i nā pihi, a ukali ʻia e ka puhi ʻana no ka metala a me ka hoʻokaʻawale ʻana, he ʻona koʻikoʻi a maikaʻi ʻole ka hana kaiapuni.ʻO ka mea hou e like me ka pō a me ke ao i ka hoʻohālikelike.
I ka hopena o Kepakemapa 2022, ua koho ʻia kēia ʻenehana ma ke ʻano he 100 o nā ʻenehana kipi i hoʻomohala ʻia ma ka honua ma 2022 e ka R&D 100 Awards.
E like me kā mākou e ʻike ai, ʻo nā pā lithium-ion he mau electrodes maikaʻi a maikaʻi ʻole, kahi mea hoʻokaʻawale, electrolyte, a me nā mea hana, akā pehea ka hui ʻana o kēia mau mea i loko o nā pā lithium-ion ʻaʻole maopopo.
I loko o nā pākahi lithium-ion, kahi mea koʻikoʻi e mālama ai i ke ʻano o ka pākaukau ʻo ia ka mea hoʻopili.
ʻO ka Quick-Release Binder hou i ʻike ʻia e Lawrence Berkeley National Laboratory noiʻi, ua hana ʻia me ka polyacrylic acid (PAA) a me ka polyethylene imine (PEI), i hoʻopili ʻia e nā mea paʻa ma waena o nā ʻātoma nitrogen i hoʻopiʻi maikaʻi ʻia i ka PEI a me nā ʻātoma oxygen i hoʻopiʻi maikaʻi ʻia i PAA.
Ke hoʻokomo ʻia ʻo Quick-Release Binder i loko o ka wai alkaline i loaʻa ka sodium hydroxide (Na+OH-), komo koke nā ion sodium i ke kahua hoʻopili, e hoʻokaʻawale ana i nā polymers ʻelua.Hoʻoheheʻe nā polymers i hoʻokaʻawale ʻia i loko o ka wai, e hoʻokuʻu ana i nā ʻāpana electrode i hoʻokomo ʻia.
Ma ke ʻano o ke kumu kūʻai, i ka wā i hoʻohana ʻia ai e hana i ka pākaukau lithium maikaʻi a me nā electrodes maikaʻi ʻole, ʻo ke kumukūʻai o kēia adhesive e pili ana i hoʻokahi hapaʻumi o nā mea ʻelua i hoʻohana pinepine ʻia.
