Te Whakamahinga Ahumahi o te Pepa Parahi Hikohiko:

Hei tētahi o ngā rauemi taketake o te umanga hiko, ko te pepa parahi hikohiko te mea nui hei hanga papa ara iahiko tā (PCB), ngā pākahiko lithium-ion, e whakamahia whānuitia ana i roto i ngā taputapu kāinga, te whakawhitiwhiti kōrero, te rorohiko (3C), me te umanga pūngao hou. I ngā tau tata nei, kua hiahiatia he whakaritenga pakari ake, he whakaritenga hou ake mō te pepa parahi me te whanaketanga o te hangarau 5G me te umanga pākahiko lithium. Ko te pepa parahi tino iti (VLP) mō te 5G, me te pepa parahi tino angiangi mō te pākahiko lithium te mea nui rawa atu i te ahunga whanaketanga hou o te hangarau pepa parahi.

Te Tukanga Hanga o te Pepa Parahi Hikohiko:

Ahakoa he rerekē ngā whakatakotoranga me ngā āhuatanga o te pepa parahi hikohiko i ia kaihanga, he rite tonu te tukanga. I te nuinga o te wā, ka whakarewahia e ngā kaihanga pepa parahi hikohiko, te waea parahi para rānei, me te parahi hikohiko parakore rite tonu hei rauemi mata, ki roto i te waikawa whanariki hei whakaputa i te wairewa parahi whanariki. Whai muri i tēnā, mā te tango i te roera whakarewa hei katote, ka whakanohoia te parahi whakarewa ki runga i te mata o te roera katote tonu mā te tauhohenga hikohiko. Ka tihorea tonutia mai i te roera katote i te wā kotahi. E mōhiotia ana tēnei tukanga ko te tukanga whakaputa pepa whakarewa me te hikohiko. Ko te taha kua tangohia (te taha maeneene) mai i te katote ko te mea e kitea ana i runga i te mata o te papa whakakī, PCB rānei, ā, ko te taha whakamuri (e mōhiotia whānuitia ana ko te taha taratara) ko te mea e pāngia ana e te raupapa maimoatanga mata, ā, ka herea ki te kapia i roto i te PCB. Ka hangaia te pepa parahi taha-rua mā te whakahaere i te horopeta o ngā tāpiringa waro i roto i te hikohiko i roto i te tukanga whakaputa pepa parahi mō te pākahiko lithium.

I te wā o te electrolysis, ka heke ngā katione i roto i te electrolyte ki te cathode, ā, ka whakaitihia i muri i te whiwhinga i ngā irahiko i runga i te cathode. Ka waikurahia ngā anion i muri i te hekenga ki te anode me te ngaronga o ngā irahiko. E rua ngā irahiko e honoa ana i roto i te otinga parahi whanariki me te iahiko tika. Kātahi ka kitea kua wehea te parahi me te hauwai i runga i te cathode. Ko te tauhohenga penei:

Cathode: Cu2+ +2e → Cu 2H+ +2e → H2↑
Anode: 4OH- -4e → 2H2O + O2↑
2SO42-+2H2O -4e → 2H2SO4 + O2↑

I muri i te maimoatanga o te mata o te katote, ka taea te tihore i te paparanga parahi i whakatakotoria ki runga i te katote, kia whiwhi ai i tētahi matotoru o te pepa parahi. Ko te pepa parahi me ētahi mahi ka kiia ko te pepa parahi.
