1. Ngā take poke i muri i te hangarua i te phosphate rino lithium
He nui te mākete hangarua pākahiko hiko, ā, e ai ki ngā umanga rangahau e tika ana, e matapaetia ana ka eke te tapeke o ngā pākahiko hiko kua reti o Haina ki te 137.4MWh i te tau 2025.
Te tango ngā pākahiko phosphate rino lithiumHei tauira, e rua ngā huarahi matua mō te hangarua me te whakamahi i ngā pākahiko hiko kua reti: ko tētahi ko te whakamahi i ngā papaaho, ko tētahi ko te wetewete me te hangarua.
Ko te whakamahinga o ngā pākahiko cascade e pā ana ki te whakamahinga o ngā pākahiko hiko lithium rino phosphate me te toenga kaha i waenga i te 30% ki te 80% i muri i te wetewete me te whakakotahitanga, ā, ka whakamahia ki ngā wāhi iti te mātotoru o te pūngao pēnei i te rokiroki pūngao.
E ai ki te ingoa, ko te wetewete me te hangarua ko te wetewete i ngā pākahiko hiko rino phosphate lithium ina iti iho i te 30% te kaha e toe ana, ā, ko te whakahokinga mai o ā rātou rauemi mata, pērā i te lithium, te phosphorus, me te rino i roto i te irahiko pai.
Mā te wetewete me te hangarua i ngā pākahiko lithium-ion ka taea te whakaiti i te keri i ngā rauemi mata hou hei tiaki i te taiao, ā, he nui hoki te uara ōhanga, ka tino whakaiti i ngā utu keri, ngā utu hanga, ngā utu mahi, me ngā utu tahora raina whakaputa.
Ko te arotahi o te wetewete me te hangarua i ngā pākahiko lithium-ion ko ngā mahi e whai ake nei: tuatahi, ko te kohikohi me te whakarōpū i ngā pākahiko lithium para, kātahi ka wetewete i ngā pākahiko, ā, i te mutunga, ka wehea me te whakapai ake i ngā konganuku. I muri i te mahi, ka taea te whakamahi i ngā konganuku me ngā rauemi kua whakahokia mai mō te hanga pākahiko hou, i ētahi atu hua rānei, ka nui te penapena utu.
Heoi, ināianei kei te pāngia katoatia e tētahi rōpū kamupene hangarua pākahiko, pērā i te apiti o Ningde Times Holding Co., Ltd., a Guangdong Bangpu Circular Technology Co., Ltd., tētahi take uaua: ka puta mai ngā hua paitini me ngā poke kino i te hangarua pākahiko. E hiahia ana te mākete ki ngā hangarau hou hei whakapai ake i te poke me te paitini o te hangarua pākahiko.
2. I kitea e LBNL ngā rauemi hou hei whakaoti rapanga parahanga i muri i te hangarua pākahiko.
Nō nā tata nei, i kī te Lawrence Berkeley National Laboratory (LBNL) i te Hononga o Amerika kua kitea e rātou tētahi rauemi hou ka taea te hangarua i ngā pākahiko lithium-ion para me te wai anake.
I whakatūria te Lawrence Berkeley National Laboratory i te tau 1931, ā, e whakahaerehia ana e te Whare Wānanga o California mā te Tari Pūtaiao o te Tari Pūngao o Amerika. Tekau mā ono ngā Tohu Nobel kua riro i a ia.
Ko te rauemi hou i hangaia e te Lawrence Berkeley National Laboratory e kiia ana ko te Quick-Release Binder. Ka taea te hangarua ngāwari i ngā pākahiko lithium-ion i hangaia mai i tēnei rauemi, he pai mō te taiao, ā, kāore he paitini. Me wetewete noa iho, ka maka ki roto i te wai kawakore, ka rūrū mārie kia wehea ngā huānga e hiahiatia ana. Kātahi ka tātarihia ngā konganuku i roto i te wai, ka whakamarokehia.
Ki te whakatauritea ki te hangarua lithium-ion o nāianei, arā, ko te haehae me te huri i ngā pākahiko, ā, muri iho ko te tahunga hei wehewehe i te konganuku me ngā huānga, he nui te paitini, ā, he ngoikore te mahi taiao. He rite tonu te rauemi hou ki te ao me te pō ki te whakataurite.
I te mutunga o Hepetema 2022, i whiriwhiria tēnei hangarau hei tētahi o ngā hangarau auaha 100 i whakawhanakehia puta noa i te ao i te tau 2022 e ngā Tohu R&D 100.
E mōhio ana tātou, he mea tito ngā pākahiko lithium-ion i ngā irahiko pai me ngā irahiko kino, he wehewehe, he irahiko hiko, me ngā rauemi hanganga, engari kāore anō kia tino mōhiotia me pēhea te whakakotahitanga o ēnei wāhanga i roto i ngā pākahiko lithium-ion.
I roto i ngā pākahiko lithium-ion, ko te piripiri he rauemi nui e pupuri ana i te hanganga o te pākahiko.
Ko te Quick-Release Binder hou i kitea e ngā kairangahau o te Lawrence Berkeley National Laboratory he mea hanga ki te waikawa polyacrylic (PAA) me te polyethylene imine (PEI), e honoa ana mā roto i ngā hononga i waenga i ngā ngota hauota kua utua pai i roto i te PEI me ngā ngota hāora kua utua kino i roto i te PAA.
Ina whakanohoia te Quick-Release Binder ki roto i te wai kawakore kei roto ko te konutai hauwai (Na+OH-), ka uru ohorere ngā katote konutai ki te pae piri, ka wehea ngā pūmua e rua. Ka rewa ngā pūmua kua wehea ki roto i te wai, ka tukuna ngā wāhanga hiko kua whakauruhia.
Mō te utu, ina whakamahia hei hanga i ngā irahiko pai me ngā irahiko kino mō te pākahiko lithium, ko te utu o tēnei piripiri he tata ki te kotahi-tekau o ngā mea e rua e whakamahia whānuitia ana.
