He aha ngā painga o te pākahiko rokiroki hiko?

Te ara hangarau o te umanga rokiroki pūngao o Haina – te rokiroki pūngao hikohiko: I tēnei wā, ko ngā rauemi katote noa o ngā pākahiko lithium ko te lithium cobalt oxide (LCO), te lithium manganese oxide (LMO), te lithium rino phosphate (LFP) me ngā rauemi ternary. Ko te lithium cobaltate te rauemi katote hokohoko tuatahi me te ngaohiko teitei, te kiato tap teitei, te hanganga pumau me te haumaru pai, engari he nui te utu me te iti o te kaha. He iti te utu me te ngaohiko teitei o te lithium manganate, engari he ngoikore tana mahi huringa, ā, he iti hoki tona kaha. Ka rerekē te kaha me te utu o ngā rauemi ternary i runga i te ihirangi o te nikara, te cobalt me ​​te manganese (hei tāpiri atu ki te NCA). He teitei ake te kiato pūngao whānui i te lithium rino phosphate me te lithium cobaltate. He iti te utu o te lithium rino phosphate, he pai te mahi huringa me te haumaru pai, engari he iti tana tūāpapa ngaohiko me te iti o tana kiato whakakī, ka hua ake he iti te kiato pūngao whānui. I tēnei wā, ko te rāngai hiko e whakahaerehia ana e te rino ternary me te lithium, ko te rāngai kai he lithium cobalt. Ka taea te wehewehe i ngā rauemi hiko kino ki ngā rauemi waro me ngā rauemi kore-waro: ko ngā rauemi waro ko te karāpeti horihori, te karāpeti tūturu, ngā porowhita waro mesophages, te waro ngohengohe, te waro mārō, me ētahi atu; ko ngā rauemi kore-waro ko te titanate lithium, ngā rauemi hanga-silicon, ngā rauemi hanga-tine, me ētahi atu. Ko te karāpeti tūturu me te karāpeti horihori ngā mea e whakamahia whānuitia ana i tēnei wā. Ahakoa he painga te karāpeti tūturu i te utu me te kaha motuhake, he iti tōna roa huringa, ā, he ngoikore tōna ōritetanga; Heoi, he taurite ngā āhuatanga o te karāpeti horihori, he pai te mahi tohanga me te hototahi pai ki te electrolyte. Ko te karāpeti horihori te nuinga e whakamahia ana mō ngā pākahiko hiko waka nui-kaha me ngā pākahiko lithium kaihoko teitei, ko te karāpeti tūturu ia e whakamahia ana mō ngā pākahiko lithium iti me ngā pākahiko lithium kaihoko whānui. Kei te rangahau tonu me te whakawhanake i ngā rauemi hanga-silicon i roto i ngā rauemi kore-waro. Ka taea te wehewehe i ngā wehewehe pākahiko lithium ki ngā wehewehe maroke me ngā wehewehe mākū i runga i te tukanga whakaputa, ā, ko te paninga kiriuhi mākū i roto i te wehewehe mākū te ia o te au nui. He painga me ngā ngoikoretanga o te tukanga mākū me te tukanga maroke. He iti, he ōrite te rahi o ngā pūwero o te tukanga mākū, ā, he angiangi te kiriata, engari he nui te haumitanga, he uaua te tukanga, ā, he nui te parahanga taiao. He māmā noa te tukanga maroke, he nui te uara tāpiri, ā, he pai ki te taiao, engari he uaua ki te whakahaere i te rahi me te pūwero o ngā pūwero, ā, he uaua ki te angiangi i te hua.

Ko te ara hangarau o te umanga rokiroki pūngao o Haina – te rokiroki pūngao hikohiko: te pākahiko waikawa mata te pākahiko waikawa mata (VRLA) he pākahiko ko tōna irahiko he mea hanga ki te mata me tōna waikura, ā, ko te irahiko he otinga waikawa whanariki. I roto i te āhua utu o te pākahiko waikawa mata, ko te wāhanga matua o te irahiko pai ko te hauhā mata, ā, ko te wāhanga matua o te irahiko kino ko te mata; I roto i te āhua tukunga, ko ngā wāhanga matua o ngā irahiko pai me kino ko te whanariki mata. Ko te kaupapa mahi o te pākahiko waikawa mata ko te pākahiko waikawa mata he momo pākahiko me te hauhā waro me te mata whakarewa hautai hei matū hohe pai me kino, me te otinga waikawa whanariki hei irahiko. Ko ngā painga o te pākahiko waikawa-mata ko te mekameka ahumahi kua tino pakari, te whakamahinga haumaru, te tiaki ngāwari, te utu iti, te roa o te ora ratonga, te kounga pumau, me ētahi atu. Ko ngā ngoikoretanga ko te tere utu puhoi, te iti o te kiato pūngao, te poto o te ora huringa, te ngāwari ki te whakapoke, me ētahi atu. Ka whakamahia ngā pākahiko waikawa-mata hei pūtake hiko tūmatanui i roto i ngā whakawhitiwhiti kōrero, ngā pūnaha pūngao rā, ngā pūnaha pana hiko, ngā taputapu whakawhitiwhiti kōrero, ngā pūtake hiko tārua iti (UPS, ECR, ngā pūnaha tārua rorohiko, me ētahi atu), ngā taputapu ohorere, me ētahi atu, me te hei pūtake hiko matua i roto i ngā taputapu whakawhitiwhiti kōrero, ngā waka whakahaere hiko (ngā waka hopu, ngā waka kawe aunoa, ngā waka hiko), ngā tīmatanga taputapu mīhini (ngā wiri kore aho, ngā taraiwa hiko, ngā reti hiko), ngā taputapu/taonga ahumahi, ngā kāmera, me ētahi atu.

Ko te ara hangarau o te umanga rokiroki pūngao o Haina – te rokiroki pūngao hikohiko: ko te pākahiko rere wai me te pākahiko konutai whanariki he momo pākahiko ka taea te penapena hiko me te tuku hiko mā te tauhohenga hikohiko o te takirua hiko wairewa i runga i te irahiko kore mahi. Ko te hanganga o te monomer pākahiko rere wai noa ko: ngā irahiko pai me ngā irahiko kino; He rūma irahiko e karapotia ana e te diaphragm me te irahiko; Te tāke irahiko, te papu me te pūnaha paipa. Ko te pākahiko rere-wai he taputapu rokiroki pūngao hikohiko ka taea te whakatutuki i te huringa tahi o te pūngao hiko me te pūngao matū mā te tauhohenga waikura-whakaiti o ngā matū hohe wai, kia tutuki ai te rokiroki me te tukunga o te pūngao hiko. He maha ngā momo me ngā pūnaha motuhake o te pākahiko rere wai. I tēnei wā, e whā noa iho ngā momo pūnaha pākahiko rere wai e tino akohia ana i te ao, tae atu ki te pākahiko rere wai vanadium katoa, te pākahiko rere wai konutea-pūromine, te pākahiko rere wai rino-konupora me te pākahiko rere wai konutai polysulfide/pūromine. Ko te pākahiko konutai-whanariki he mea tito mai i te irahiko pai, te irahiko kino, te irahiko hiko, te diaphragm me te anga, he rerekē tēnei i te pākahiko tuarua whānui (pākahiko waikawa-mata, pākahiko nikara-karamiuma, me ētahi atu). Ko te pākahiko konutai-whanariki he mea tito mai i te irahiko rewa me te irahiko totoka. Ko te matū hohe o te irahiko kino ko te konutai whakarewa rewa, ā, ko te matū hohe o te irahiko pai ko te whanariki wai me te tote konutai polysulfide rewa. Ko te anode o te pākahiko konutai-whanariki he mea tito mai i te whanariki wai, ko te cathode he mea tito mai i te konutai wai, ā, ko te ngongo beta-konumohe o te rauemi uku kua wehea ki waenganui. Me pupuri te pāmahana whakahaere o te pākahiko ki runga ake i te 300 °C kia mau tonu ai te irahiko i roto i te āhua rewa. Ko te ara hangarau o te umanga rokiroki pūngao o Haina - te pūtau wahie: te pūtau rokiroki pūngao hauwai he taputapu e huri tika ana i te pūngao matū o te hauwai ki te pūngao hiko. Ko te kaupapa matua ko te hauwai e tomo ana ki te anode o te pūtau wahie, ka pirau hei porotana hau me ngā irahiko i raro i te mahi a te whakakorikori, ā, ko ngā porotana hauwai i hangaia ka haere mā roto i te kiriuhi whakawhiti porotana kia tae atu ki te katote o te pūtau wahie ka honoa ki te hāora hei whakaputa wai. Ka tae ngā irahiko ki te katote o te pūtau wahie mā roto i te ara iahiko o waho hei hanga i te iahiko. Ko te tikanga, he taputapu whakaputa hiko tauhohenga hikohiko. Ko te rahi o te mākete o te umanga rokiroki pūngao o te ao - kua rua te kaha hou kua tāutahia o te umanga rokiroki pūngao - te rahi o te mākete o te umanga rokiroki pūngao o te ao - ko ngā pākahiko lithium-ion tonu te momo rokiroki pūngao matua - he painga ngā pākahiko lithium-ion o te kiato pūngao teitei, te pai o te hurihanga teitei, te urupare tere, me ētahi atu, ā, ko rātou te ōwehenga teitei rawa atu o te kaha kua tāutahia engari ko te rokiroki papu. E ai ki te pepa ma mō te whanaketanga o te umanga pākahiko lithium-ion o Haina (2022) i tukuna tahitia e EVTank me Ivy Institute of Economics. E ai ki ngā raraunga o te pepa mā, i te tau 2021, ko te tapeke o ngā tukunga o ngā pākahiko lithium-ion puta noa i te ao ka eke ki te 562.4GWh, he pikinga nui o te 91% ia tau, ā, ko tōna wāhi i roto i ngā whakaurunga rokiroki pūngao hou o te ao ka neke atu i te 90%. Ahakoa kua tīmata te aro nui ki ētahi atu momo rokiroki pūngao pēnei i te pākahiko rere-vanadium, te pākahiko konutai-ion me te hau kōpeke i ngā tau tata nei, he nui tonu ngā painga o te pākahiko lithium-ion i runga i te mahi, te utu me te ahumahi. I roto i te wā poto me te wā waenga, ko te pākahiko lithium-ion te momo rokiroki pūngao matua o te ao, ā, ka noho tonu tōna wāhi i roto i ngā whakaurunga rokiroki pūngao hou ki te taumata teitei.

Ka arotahi a Longrun-energy ki te mara o te rokiroki pūngao, ā, ka whakauruhia te turanga ratonga mekameka tuku pūngao hei whakarato i ngā otinga rokiroki pūngao mō ngā āhuatanga o te whare me te ahumahi me te arumoni, tae atu ki te hoahoa, te whakangungu huihuinga, ngā otinga mākete, te whakahaere utu, te whakahaere, te whakahaere me te tiaki, me ētahi atu. He maha ngā tau o te mahi tahi me ngā kaihanga pākahiko rongonui me ngā kaihanga inverter, kua whakarapopototia e mātou te hangarau me te wheako whanaketanga hei hanga i tētahi turanga ratonga mekameka tuku whakauru.
