Te Mahi a ngā Pūhiko Lithium-Polymer
Ko te pākahiko lithium-polymer he momo pākahiko lithium-ion e whakamahi ana i te electrolyte polymer hei reo kawe-ion. Ko te tikanga, ko ēnei pākahiko he cathode (he mea hanga i te lithium cobalt oxide, LiCoO2), he anode (he mea hanga i te graphite), me te electrolyte polymer. He mea nui tēnei electrolyte nā te mea ka āwhina i te nekehanga o ngā katote lithium i waenga i te anode me te cathode i te wā e utu ana, e wete ana hoki.
I te wā e utu ana, ka neke ngā iona lithium mai i te cathode ki te anode mā te electrolyte. Ina whakamahia te pākahiko, ka hoki ngā iona lithium mai i te anode ki te cathode, ka whakaputa i te iahiko hiko e whakamahia ana e te pona. Mā ngā electrolyte polymer ka taea te neke iona kia pai ake i ngā electrolyte wai, ā, ka pai ake te mahi a te pākahiko.

4. Huringa Ora Roa Ake
Ko te roa o te ora e pā ana ki te maha o ngā wā ka taea te whakakī anō i te pākahiko i mua i te tīmatanga o te hekenga nui o tana mahi. He roa ake te ora o ngā pākahiko lithium-polymer i ngā pākahiko nickel-cadmium (Ni-Cd) me te nickel-metal hydride (Ni-MH), arā, he roa ake te ora, ā, he iti ake te hiahia ki te whakakapinga.
5. Wā Utu Tere
Ko te tikanga, ka tere ake te utu o ngā pākahiko lithium-polymer i ētahi atu momo pākahiko. He tino whai hua tēnei mō ngā kaiwhakamahi pona e hiahia ana ki te nekeneke tere, ā, kāore e hiahia ki te roa o te wā utu.
