Kei te piki haere te rongonui o ngā waka hiko puta noa i te ao i te mea e tipu haere ana te mōhiotanga ki te hiranga o te whakaiti i ngā tukunga hau kati kōtuhi me te aro atu ki te huringa āhuarangi. Ko tētahi o ngā wāhanga matua o te waka hiko ko te pākahiko. Ka matapakihia e tēnei tuhinga te mahi a ngā pākahiko waka hiko me ngā auahatanga hou o tēnei mara.
Te Mahi a ngā Pūhiko Waka Hiko
Ko ngā pākahiko waka hiko te pūtake pūngao matua mō ngā waka hiko. Ko te nuinga o ngā waka hiko o ēnei rā e whakamahi ana i ngā pākahiko lithium-ion (Li-ion) nā te mea he nui te kaha o te pūngao me te roa o te ora. Engari me pēhea te mahi a ēnei pākahiko?
Ngā Mātāpono Taketake
Ko te tikanga, e toru ngā wāhanga matua o te pākahiko Li-ion: he anode, he cathode, me te electrolyte. Ina utua te pākahiko, ka neke ngā ion lithium mai i te cathode ki te anode mā te electrolyte, ā, ka neke anō hoki ina tukuna te pākahiko. Ka puta he iahiko hiko i tēnei tukanga hei whakakaha i ngā motuka hiko.
Te Tukanga Utu me te Whakamahinga
1. Te Utu: I te wā e utu ana, ka rere te iahiko mai i tētahi pūtake o waho ki roto i te pākahiko, ka neke ngā iona lithium mai i te cathode ki te anode ka piri ki te rauemi anode. Ka whakaputahia e tēnei tukanga he pūngao i roto i te āhua o ngā matū i roto i te pākahiko.
2. Te Tukunga: Ina whakamahia te waka, ka hoki ngā iona lithium mai i te anode ki te cathode mā te electrolyte, ka puta he iahiko e whakakaha ana i te motuka o te waka.
