1. Nā pilikia haumia ma hope o ka hana hou ʻana i ka lithium iron phosphate
He nui ka mākeke hana hou ʻana o nā pila uila, a e like me nā ʻoihana noiʻi pili, e manaʻo ʻia ka huina hōʻiliʻili o nā pila uila i hoʻomaha ʻia o Kina e hōʻea i 137.4MWh ma ka makahiki 2025.
Ke lawe nei nā pila lithium hao phosphatee like me ka laʻana, ʻelua mau ala nui no ka hana hou ʻana a me ka hoʻohana ʻana i nā pila mana i hoʻomaha ʻia: ʻo kekahi ka hoʻohana ʻana i ka cascade, a ʻo kekahi 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 pila mana lithium hao phosphate me ke koena o ka mana ma waena o 30% a 80% ma hope o ka wehe ʻana a me ka hui hou ʻana, a me ka hoʻopili ʻana iā lākou i nā wahi haʻahaʻa haʻahaʻa e like me ka mālama ʻana i ka ikehu.
ʻO ka wehe ʻana a me ka hana hou ʻana, e like me ka inoa e hōʻike nei, e pili ana i ka wehe ʻana o nā pila mana lithium hao phosphate ke emi ka mana i koe ma mua o 30%, a me ka hoʻihoʻi ʻana o kā lākou mau mea maka, e like me ka lithium, phosphorus, a me ka hao i loko o ka electrode maikaʻi.
ʻO ka wehe ʻana a me ka hana hou ʻana o nā pila lithium-ion hiki ke hōʻemi i ka hana ʻeli ʻana o nā mea maka hou e pale i ke kaiapuni a loaʻa pū kekahi waiwai waiwai nui, e hōʻemi nui ana i nā kumukūʻai mining, nā kumukūʻai hana, nā kumukūʻai hana, a me nā kumukūʻai hoʻolālā laina hana.
ʻO ke kiko o ka wehe ʻana a me ka hana hou ʻana o nā pākahiko lithium-ion, ʻo ia hoʻi nā hana aʻe: ʻo ka mua, e hōʻiliʻili a hoʻokaʻawale i nā pākahiko lithium neoneo, a laila e wehe i nā pākahiko, a laila 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 pākahiko 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 ʻoihana hana hou ʻana i nā pila, e like me ka lālā ʻo Ningde Times Holding Co., Ltd. ʻo Guangdong Bangpu Circular Technology Co., Ltd., ke kū nei lākou a pau i kahi pilikia paʻakikī: e hoʻopuka ka hana hou ʻana i nā pila i nā huahana ʻawahia a hoʻokuʻu i nā mea haumia ʻino. Pono koke ka mākeke i nā ʻenehana hou e hoʻomaikaʻi i ka haumia a me ka ʻawahia o ka hana hou ʻana i nā pila.
2. Ua loaʻa iā LBNL nā mea hou e hoʻoponopono ai i nā pilikia haumia ma hope o ka hana hou ʻana o ka pila.
I kēia mau lā iho nei, 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 pila lithium-ion ʻōpala me ka wai wale nō.
Ua hoʻokumu ʻia ʻo Lawrence Berkeley National Laboratory i ka makahiki 1931 a ua mālama ʻia e ke Kulanui o Kaleponi no ke Keʻena ʻEpekema o ka US Department of Energy. Ua lanakila ia i 16 mau makana Nobel.
ʻO ka mea hou i hana ʻia e ka Lawrence Berkeley National Laboratory ua kapa ʻia ʻo Quick-Release Binder. Hiki ke hana hou ʻia nā pila Lithium-ion i hana ʻia mai kēia mea me ka maʻalahi, palekana i ke kaiapuni, a ʻaʻohe mea ʻawahia. Pono wale nō e wehe ʻia a hoʻokomo i loko o ka wai alkaline, a lūlū mālie ʻia e hoʻokaʻawale i nā mea e pono ai. A laila, kānana ʻia nā metala mai loko mai o ka wai a hoʻomaloʻo ʻia.
Ke hoʻohālikelike ʻia me ka hana hou ʻana o ka lithium-ion o kēia manawa, kahi e pili ana i ka haehae ʻana a me ka wili ʻana i nā pila, a ukali ʻia e ke ahi no ka hoʻokaʻawale ʻana i ka metala a me nā mea, he ʻawahia nui kona a he hana maikaʻi ʻole hoʻi i ke kaiapuni. Ua like ka mea hou me ka pō a me ke ao i ka hoʻohālikelike ʻana.
I ka hopena o Kepakemapa 2022, ua koho ʻia kēia ʻenehana ʻo ia kekahi o nā ʻenehana kipi 100 i hoʻomohala ʻia ma ka honua holoʻokoʻa i ka makahiki 2022 e ka R&D 100 Awards.
E like me kā mākou e ʻike nei, aia nā pākahiko lithium-ion i nā electrodes maikaʻi a me nā electrodes maikaʻi ʻole, kahi mea hoʻokaʻawale, electrolyte, a me nā mea kūkulu, akā ʻaʻole maopopo pehea e hui pū ʻia ai kēia mau ʻāpana i nā pākahiko lithium-ion.
I loko o nā pila lithium-ion, he mea koʻikoʻi ka mea hoʻopili e mālama i ke ʻano o ka pila.
ʻO ka Quick-Release Binder hou i ʻike ʻia e nā kānaka noiʻi o Lawrence Berkeley National Laboratory ua hana ʻia me ka polyacrylic acid (PAA) a me ka polyethylene imine (PEI), i hoʻopili ʻia e nā pilina ma waena o nā ʻātoma nitrogen i hoʻopiʻi maikaʻi ʻia ma PEI a me nā ʻātoma oxygen i hoʻopiʻi maikaʻi ʻole ʻia ma PAA.
Ke kau ʻia ka Quick-Release Binder i loko o ka wai alkaline i loaʻa ka sodium hydroxide (Na+OH-), komo koke nā ion sodium i kahi hoʻopili, e hoʻokaʻawale ana i nā polymers ʻelua. Hoʻoheheʻe ʻia 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 kumukūʻai, i ka wā e hoʻohana ʻia ai e hana i nā electrodes maikaʻi a me nā electrodes maikaʻi ʻole o ka pā lithium, ʻo ke kumukūʻai o kēia mea hoʻopili ma kahi o hoʻokahi hapaʻumi o nā mea ʻelua i hoʻohana pinepine ʻia
