Hei wāhanga nui o ngā waka hiko, ka pāngia te taiao e ngā pākahiko lithium-ion i te wā e whakamahia ana. Mō tētahi tātaritanga pānga taiao whānui, i whiriwhiria ngā kete pākahiko lithium-ion, he 11 ngā rauemi rerekē, hei kaupapa rangahau. Mā te whakatinana i te tikanga aromatawai huringa ora me te tikanga taumaha entropy hei ine i te kawenga taiao, ka hangaia he pūnaha aromatawai taupū maha-taumata e hangai ana ki ngā āhuatanga o te pākahiko taiao.
He mea nui te tere o te whanaketanga o te umanga kawe waka1 ki te whanaketanga ōhanga me te whanaketanga pāpori. I taua wā anō, he nui hoki ngā wahie pūmua e pau ana, ka puta ai te parahanga nui ki te taiao. E ai ki te IEA (2019), tata ki te hautoru o ngā tukunga CO2 o te ao e ahu mai ana i te rāngai kawe waka. Hei whakaiti i te tono nui mō te pūngao me te taumahatanga taiao o te umanga kawe waka o te ao, ko te whakaurunga hiko o te umanga kawe waka tetahi o ngā mahi matua hei whakaiti i ngā tukunga parahanga. Nō reira, ko te whakawhanaketanga o ngā waka e pai ana ki te taiao me te pumau, inā koa ko ngā waka hiko (EV), kua waiho hei kōwhiringa whai hua mō te umanga motuka.
Mai i te Mahere Tau Rima 12 (2010-2015), kua whakatau te kāwanatanga o Haina ki te whakatairanga i te whakamahinga o ngā waka hiko hei whakapai ake i te haereere. Heoi, nā te raruraru ōhanga nui kua akiakihia ngā whenua ki te pāngia e ngā raruraru pēnei i te raruraru pūngao, te pikinga o ngā utu wahie pūmua, te kore mahi nui, te pikinga o te pikinga utu, me ētahi atu, ā, kua pāngia te hinengaro pāpori, te kaha o te kaihoko me te whakatau a te kāwanatanga. Nō reira, ko te iti o te whakaae me te whakaae ki ngā waka hiko ka aukati i te whakaurunga wawe o ngā waka hiko ki te mākete.
I te ritenga kē, i heke tonu te hoko o ngā waka wahie, ā, i puhoi haere te ia o te tipu o te tokomaha o ngā kaipupuri. Arā, nā te whakatinanatanga o ngā ture me te ara ake o te mōhiotanga taiao, kua rerekē te hoko o ngā waka wahie tuku iho i te hoko o ngā waka hiko, ā, kei te tere piki haere te tere o te urunga mai o ngā waka hiko. I tēnei wā, ko ngā pākahiko lithium-ion (LIB) te whiringa pai rawa atu i roto i te ao o ngā waka hiko nā te mea he mama, he pai te mahi, he nui te kaha o te pūngao me te nui o te putanga mana. Hei tāpiri, ko ngā pākahiko lithium-ion, hei hangarau matua mō ngā pūnaha rokiroki pākahiko, he nui hoki te kaha ki te whakawhanake i te pūngao pumau me te whakaiti nui i ngā tukunga waro.
I roto i te tukanga whakatairanga, i ētahi wā ka tirohia ngā waka hiko he waka kore-tukunga, engari he nui te pānga o te hanga me te whakamahinga o ā rātou pākahiko ki te taiao. Nō reira, kua aro nui ake ngā rangahau hou ki ngā painga taiao o ngā waka hiko. He nui ngā rangahau mō ngā wāhanga e toru o te hanga, te whakamahinga me te whakakorenga o ngā waka hiko, i tangohia e toru o ngā pākahiko lithium nickel cobalt manganese oxide (NCM) me te lithium iron phosphate (LFP) e whakamahia whānuitia ana i te mākete waka hiko Haina hei kaupapa rangahau, ā, i whakahaerehia he tātaritanga motuhake o ēnei pākahiko e toru i runga i te aromatawai huringa ora (LCA) o ngā wāhanga o te hanga, te whakamahinga me te hangarua o ngā pākahiko kukume. E whakaatu ana ngā hua he pai ake te mahi taiao o te pākahiko lithium iron phosphate i te pākahiko toru i roto i ngā āhuatanga whānui, engari ko te whai huatanga o te pūngao i te wāhanga whakamahinga kāore i te pai ki te pākahiko toru, ā, he nui ake te uara hangarua.
