Pendahuluan
Ko te matū hikohiko he peka o te matū e ako ana i te whanaungatanga i waenga i ngā tauhohenga matū me te iahiko hiko. Ko te arotahi matua o tēnei mara ko te hurihanga o te pūngao matū ki te pūngao hiko, me te hurihanga anō hoki. He mea nui te matū hikohiko i roto i ngā āhuatanga maha o te ao hou, mai i ngā pākahiko me ngā pūtau wahie ki te whakamahine whakarewa me te hanga hikohiko o ngā matū. Ka arotakehia e tēnei tuhinga ngā kaupapa matua o te matū hikohiko, ōna mātāpono mahi, me ōna tono nui e whakarerekē ana i te āhua o tō tātou noho me te mahi.
Ngā Kaupapa Taketake o te Hikohiko
Tauhohenga Redox
He hononga tata te matū hiko ki ngā tauhohenga whakahāora-whakaiti (redox). I roto i ēnei tauhohenga, ka whakawhitia ngā irahiko mai i tētahi momo ki tētahi atu. Ko te momo e ngaro ana ngā irahiko ka kiia he whakahāora, ko te momo ia e whiwhi ana i ngā irahiko ka kiia he whakahāora. E rua ngā haurua-tauhohenga o ia tauhohenga redox: he haurua-tauhohenga whakahāora me te haurua-tauhohenga whakaiti.
Pūmanawa Hikohiko
He pūmanawa hiko motuhake tō ia haurua-tauhohenga, e ine ana i te āhua o te momo kia waikuratia, kia whakaititia rānei. Ka tautuhia ngā pūmanawa hiko paerewa e pā ana ki te hiko hauwai paerewa (SHE), e tautuhia ana he pūmanawa o te 0 volts.
Te Ture a Faraday
Ko ngā ture a Faraday e whakahaere ana i te matū hiko, e whakaatu ana i te whanaungatanga tauanga i waenga i te nui o te hiko e whakamahia ana me te nui o te matū kua whakaitihia, kua waikurahia rānei. E kī ana te ture tuatahi a Faraday ko te papatipu o te matū kua whakatakotoria, kua rewa rānei i te hikohiko he rite ki te nui o te utu hiko e tukuna ana i roto i te otinga. E kī ana te ture tuarua a Faraday mō te papatipu kotahi, ka rerekē te nui o te whakatakotoranga o te matū i runga i te maha o ngā irahiko e uru ana ki te tauhohenga redox o ia matū.
Ngā Pūtau Galvanic me ngā Pūtau Hikohiko
E rua ngā momo matua o ngā pūtau hiko e uru ana ki te matū hiko: ko ngā pūtau konukōre me ngā pūtau hikohiko. Ka hurihia e ngā pūtau konukōre te pūngao matū hei pūngao hiko, e kitea ana i roto i ngā pākahiko. He rerekē, ka whakamahia e ngā pūtau hikohiko te pūngao hiko hei akiaki i ngā tauhohenga matū kore-tūpono, ā, he maha ngā wā ka whakamahia i roto i te whakamahine whakarewa me te hanga hiko.
Ngā Whakamahinga Hikohiko
Ngā Pūhiko me ngā Pūhiko Whakaemi
Ko ngā pākahiko te tauira tino noa o te tono hikohiko. Ka mahi ngā pākahiko i runga i te kaupapa o te pūtau galvanic, ka puta he pūngao hiko i te tauhohenga redox ohorere. He maha ngā momo pākahiko, tae atu ki ngā pākahiko waikawa-mata (ngā kaiwhakaemi), ngā pākahiko lithium-ion, me ngā pākahiko kawakore. He painga me ngā ngoikoretanga o ia momo, me ngā tono motuhake. Hei tauira, he whānuitia te whakamahinga o ngā pākahiko lithium-ion i roto i ngā taputapu hiko kawe pēnei i ngā waea pūkoro me ngā pona nā te mea he nui te kaha o te pūngao me te tino pai o te whakahou.
Pūtau Wahie
He taputapu te pūtau wahie e huri ana i te pūngao matū o te wahie (te nuinga o te wā ko te hauwai) hei hiko mā te tauhohenga hiko me te hāora. He pai ake te mahi a ngā pūtau wahie i ngā tipu hiko tuku iho, ā, he iti ake ngā tukunga e puta mai ana. Kei te piki haere te whakamahinga o ngā pūtau wahie i roto i ngā waka hiko, ā, hei pūtake hiko rerekē hoki e pai ana ki te taiao.
Te hikohiko
Ko te hikohiko te tukanga whakamahi i te iahiko hei whakaoho i tētahi tauhohenga matū kore-ā-pūmau. Ko tētahi whakamahinga kei roto i te umanga whakamahine whakarewa, pērā i te hanga konumohe mai i te konganuku bauxite. Ka whakamahia hoki te hikohiko hei whakaputa i te chlorine me te konutai hauwaiwai mai i te otinga konutai hauwaiwai, me te whakaputa hauwai mai i te wai.
Te Parenga Waikura me te Katorika
Ko tētahi o ngā raruraru nui i roto i te hangarau me te hanga ko te waikura, arā, te tukanga o te pirau o ngā rauemi nā ngā tauhohenga hikohiko me tōna taiao. Ka taea e te waikura te whakararu i ngā hanganga me ngā mate ōhanga. Ko te tiaki katotika he tikanga e whakamahia ana hei ārai i te waikura, e whakamahia ana he iahiko hei ārai i ngā tauhohenga redox e puta ai te waikura. He whānuitia te whakamahinga o tēnei tikanga hei tiaki i ngā paipa, ngā tāke, me ngā hanganga o raro i te wai.
Pūoko Hikohiko
Ka whakamahia ngā pūoko hikohiko hei kimi me te ine i te kukū motuhake o tētahi matū i roto i tētahi otinga. Ko ngā mita huka, e whakamahia ana e te hunga mate huka hei aroturuki i ngā taumata huka toto, he tauira o tētahi tono pūoko hikohiko. Ka mahi ēnei pūoko i runga i ngā huringa o te iahiko hiko i hangaia e te tauhohenga redox i waenga i te huka me te matū i te irahiko pūoko.
Te tukatuka para
He mea nui anō hoki te hangarau hikohiko i roto i te maimoatanga wai me te wai para. Hei tauira, ko te hikohiko whakapūmau he tikanga e whakamahi ana i te iahiko hiko hei whakaputa i ngā poke mai i te wai para. He tikanga whai hua tēnei mō te tango i ngā konganuku taumaha, ngā mea rauropi, me ngā moroiti mai i te wai.
Te Rokiroki Pūngao
I te mea kua piki haere te aro ki te pūngao hou, kua noho te rokiroki pūngao hei wāhanga nui o te rangahau. Ko ngā pākahiko rere-redoks he momo pākahiko e penapena ana i te pūngao i roto i ngā otinga irahiko e rua, e taea ai te rokiroki pūngao nui ake. He pai tēnei hangarau mō te penapena pūngao mai i ngā pūtake hou pēnei i te hiko o te rā me te hau.
Ngā Whanaketanga Hou
Kei te tere tonu te whanaketanga o ngā rangahau i roto i te matū hiko, me ngā kitenga hou e tuku ana i te pūmanawa nui mō te auahatanga. Ko tētahi wāhanga mahi ko te whakawhanake i ngā pākahiko haumaru ake, whai hua ake, me te pai ake ki te taiao. Kei te haere tonu te rangahau ki ngā rauemi katote hou, ngā irahiko totoka, me ngā hangarau takai modular.
Ko tētahi atu mara hou ko te rangahau i te nanoelectrochemistry, te wāhi e whakahaerehia ai ngā tauhohenga hiko i te tauine nanometer. Ka huaki ake tēnei i ngā pūmanawa hou mō ngā pūoko, ngā taputapu hiko iti, me te whakamahinga pūngao whai hua ake.
Whakamutunga
Ko te matū hiko, me ōna mātāpono taketake me ōna whakamahinga whānui, he mahi nui ki te whakatairanga i te ahunga whakamua hangarau me te whakapai ake i te kounga o tō tātou oranga. Mai i ngā pākahiko e whakakaha ana i ā tātou taputapu hiko ki ngā pūtau wahie e oati ana i te heke mai o te pūngao ma, mai i ngā hangarau maimoatanga wai ki te tiaki i ngā hanganga mai i te waikura, ka pā te matū hiko ki ngā āhuatanga maha o ō tātou oranga. I te haere tonu o te rangahau me te auahatanga ki te ahu whakamua, ka taea e tātou te tumanako atu ki ētahi atu putanga hou e whakamahi ana i te kaha o te matū hiko ki te aro atu ki ngā wero o te ao ā muri ake nei.
