Kuleli zwe lanamuhla ugesi uwumthombo oyinhloko wamandla.Uma siqalaza indawo esihlala kuyo igcwele izinto zikagesi.Ugesi uthuthukise ukuphila kwethu kwansuku zonke ngendlela yokuthi manje sesiphila ukuphila okulula kakhulu uma kuqhathaniswa naleyo yamakhulu eminyaka ambalwa edlule.Ngisho nezinto eziyisisekelo ezifana nokuxhumana, ukuhamba nempilo kanye nemithi ziye zavela kangangokuthi cishe yonke into manje sekulula ukuyenza.Uma ukhuluma ngokuxhumana ezikhathini zangaphambili abantu babethumela izincwadi futhi lezo zincwadi zazithatha isikhathi esingaphezu kwezinyanga eziyisithupha noma unyaka ukufika lapho beya khona futhi umuntu owayezobhala lezo zincwadi azibuyisele kwakuthatha ezinye izinyanga eziyisithupha noma unyaka ukufinyelela umuntu owabhala incwadi ekuqaleni.Nokho-ke kulezi zinsuku lokhu akuyona into exakile noma ubani angakhuluma nanoma ubani ngosizo lwemiyalezo embalwa engathunyelwa kuyo nge-Facebook, WhatsApp nanoma iyiphi enye i-app yeselula.Awukwazi ukuthumela nje imiyalezo kuphela kodwa ungakwazi ukuxhumana ngosizo lwezingcingo zezwi ezingenziwa ezindaweni ezikude.Ngokufanayo nokuhamba, abantu manje sebeyakwazi ukuguqula amabanga abo okuhamba abe izindawo zesikhathi esifushane kakhulu.Isibonelo uma ngekhulu leminyaka elidlule kuthathe Uma kuthatha Usuku noma ezimbili ukufika endaweni kulezi zinsuku ungakwazi ukufinyelela kuyo leyo ndawo phakathi nehora noma ngaphezulu.Impilo nemithi nayo isithuthukile futhi konke lokhu kungenxa kagesi kanye nesimanjemanje kwemboni.
Ngakho liyini ibhethri kumele siqale siqonde ibhethri.Ibhethri idivayisi kagesi ekwazi ukuguqula amandla ekhemikhali agcinwe ngaphakathi kwayo ngendlela yokusabela.Ibhethri libhekana nokusabela okumbalwa okwaziwa ngokuthi ukusabela kwe-redox.Ukusabela kwe-redox kuhlanganisa ukusabela kwe-oxidation kanye nokusabela kokunciphisa.Ukusabela kokunciphisa kuwuhlobo lokusabela lapho ama-electron engezwa ku-athomu kuyilapho ukusabela kwe-oxidation kuwuhlobo lokusabela lapho ama-electron akhishwa e-athomu.Lokhu kusabela kuhambisana ngaphakathi ohlelweni lwamakhemikhali ebhethri futhi ekugcineni kuguqule amandla amakhemikhali abe ekagesi.Izingxenye zebhethri ziyafana kuzo zonke izinhlobo zamabhethri.Ibhethri liqukethe cishe izingxenye ezintathu ezibalulekile.Ingxenye yokuqala ebalulekile yaziwa ngokuthi i-cathode, ingxenye yesibili ebalulekile yaziwa ngokuthi i-anode futhi okokugcina kodwa hhayi ingxenye encane ebalulekile eyaziwa ngokuthi isixazululo se-electrolyte.I-oda lokuphuma liyisiphetho esinegethivu sebhethri futhi likhipha ama-electron ahamba aye ngasekugcineni kwebhethri ngakho-ke adale ukugeleza kwama-electron abalulekile ekukhiqizeni amandla amanje.
Isho ukuthini i-AGM kushaja yebhethri?
I-AGM imele i-absorbent glass mat.Ukuze siqonde ukuthi iyini i-glass mat emuncayo kufanele siqale siqonde ukuthi kuyini ukucushwa kwebhethri okuvamile.Ekucushweni kwebhethri okuvamile kwaziwa ngokuthi ukucushwa kwe-SLA.Ukucushwa kwe-SL kusho ibhethri le-asidi yomthofu evaliwe.Okuqukethe i-electrode esekelwe kumthofu kanye nesisombululo se-electrolyte esine-lead oxide.Ebhethrini elilula le-lead oxide kukhona ibhuloho likasawoti elikhona phakathi kwama-electrode amabili ibhuloho likasawoti lingenziwa ngosawoti owenziwe ngenhlanganisela ye-potassium noma i-chloride nanoma yiluphi olunye uhlobo lwamaminerali.Kodwa esimweni sebhethri ye-glass mat edonsayo lokhu kuhlukile.Ebhethrini le-mat yengilazi elimuncayo kune-fiberglass ebekwe phakathi kwe-negative kanye nama-electrode aqondile ebhethri ukuze ama-electron akwazi ukudlula ngendlela ecwengekile.Le ndoda inhle kakhulu ngoba isebenza njengesipontshi futhi uma isebenza njengesipontshi kukhona isixazululo se-electrolyte esikhona phakathi kwe-positive kanye ne-negative ekupheleni kwebhethri ayichithi ngaphandle kwebhethri kunalokho idonswa yi-fiberglass yethulwe ngaphakathi kwebhuloho elikhona phakathi kwama-electrode ebhethri ephozithivu nenegethivu.Ngakho-ke ibhethri le-AGM kufanele liphathwe ngokucophelela mayelana nenqubo yokushaja.Futhi ibhethri le-AGM lishaja cishe izikhathi ezinhlanu ngokushesha uma liqhathaniswa nebhethri elivamile.
Isho ukuthini i-AGM ngebhethri lemoto?
I-AGM ebhethrini lemoto isho umata wengilazi omuncayo.Futhi ibhethri likamata wengilazi elimuncayo liwuhlobo olukhethekile lwebhethri oluqukethe i-fiberglass ekhona phakathi kwama-electrode amabili.Lolu hlobo lwebhethri futhi ngezinye izikhathi lwaziwa ngokuthi ibhethri elomile ngoba i-fiberglass ngokuyisisekelo isipontshi.Okwenziwa yilesi sipontshi ukuthi sidonsa isixazululo se-electrolyte esikhona ngaphakathi kwebhethri futhi ngenxa yalokho sihlanganisa ama-ion noma ama-electron.Lapho isipontshi simunca isixazululo se-electrolyte ama-electron awabi nankinga yokusabela ngezindonga zebhethri futhi hhayi nje ukuthi isisombululo se-electrolyte ebhethrini ngeke sichitheke lapho ibhethri livuza noma kwenzeka into enjalo.
Isho ukuthini i-AGM ebandayo eshajani yebhethri?
I-AGM ebandayo eshajani yebhethri ngokuyisisekelo isho ukuthi iwuhlobo lweshaja eqondene namabhethri e-AGM kuphela.Lolu hlobo lweshaja luqondene ngqo nalezi zinhlobo zamabhethri kuphela ngoba lawa mabhethri awafani nebhethri elijwayelekile le-asidi yomthofu.Ibhethri elijwayelekile elinomthofu liqukethe i-electrolyte entanta ngokukhululekile phakathi kwama-electrode amabili futhi ayidingi ukushajwa ngeshaja yebhethri yohlobo lwe-EGM.Nokho ibhethri lohlobo lwe-AGM liqukethe ingxenye ekhethekile ekhona phakathi kwama-electrode amabili.Ingxenye ekhethekile yaziwa ngokuthi i-absorbent glass mat.Le mat yengilazi emuncayo iqukethe ukuhlinzeka ngemicu yengilazi ekhona ebhulohweni elixhumanisa ama-electrode amabili ndawonye.Ibhuloho libekwe ohlotsheni lwesisombululo se-electrolyte esimuncwa ibhuloho.Inzuzo enkulu ibhethri le-AGM elinalo ngaphezu kwebhethri elijwayelekile le-asidi eholayo ukuthi futhi ibhethri ye-AGM ayichithi ngokweqile.Inamandla okushaja ngokushesha uma kuqhathaniswa nebhethri elivamile le-asidi yomthofu.
