Amaseli e-Voltaic: Inguquko Ezweni Lamandla
I-Pendahuluan
Izwe lanamuhla lithembele kakhulu kugesi cishe kuzo zonke izici zokuphila kwansuku zonke, kusukela ezidingweni zasekhaya kuya embonini enkulu. Ngakho-ke, ukuthuthukiswa kwemithombo yamandla esebenza kahle futhi eqhubekayo kubalulekile. Enye into entsha ethokozisayo emhlabeni wamandla yiseli le-Voltaic, eliphawule ingqophamlando ekuthuthukisweni kobuchwepheshe bokugcina amandla kagesi. Lesi sihloko sihlola umlando, izimiso zokusebenza, ukusetshenziswa, kanye nomthelela weseli le-Voltaic.
Umlando Nemvelaphi
Iseli le-Voltaic liqanjwe ngomsunguli walo, u-Alessandro Volta, isazi sefiziksi sase-Italy esaziwa ngocwaningo lwakhe ngamandla kagesi kanye namandla kagesi. Ngo-1800, u-Alessandro Volta wenza intuthuko enkulu ngokudala idivayisi eyaziwa ngokuthi "i-Voltaic Pile." Lokhu kusungulwa kwakuyibhethri lokuqala likagesi elikwazi ukukhiqiza ukugeleza okuqhubekayo kogesi oqondile (DC). Lokhu kusungulwa kwavula indlela yokuthuthukiswa kobuchwepheshe bukagesi njengoba sibazi namuhla.
UVolta wakha iseli kagesi ngokusekelwe ekutholeni kwakhe ekusebenzisaneni kwamakhemikhali phakathi kwezinsimbi ezimbili ezingafani ezibekwe esixazululweni se-electrolyte. Ukuhlola kwakhe kwaqala ngezinsimbi ezimbili, i-zinc nethusi, ngayinye ixhunywe ungqimba lwamanzi anosawoti. Imiphumela yokuhlolwa kwakhe yabonisa ukugeleza kukagesi okuqhubekayo, okufakazela ukuthi ukusabela kwamakhemikhali kungasetshenziswa ukukhiqiza amandla kagesi.
Isimiso Sokusebenza Seseli Le-Voltaic
Iseli le-voltaic liqukethe ama-electrode amabili enziwe ngezinsimbi ezahlukene, ngokuvamile i-zinc (Zn) nethusi (Cu), kanye ne-electrolyte esebenza njengendlela yokusabela kwamakhemikhali. Ukusebenza kwayo kulula kodwa kuyasebenza. Lezi zinsimbi zinamakhono ahlukene e-electrode, okubangela ukuthi ama-electron adlulele kusuka kwenye insimbi aye kwenye ngendlela yangaphandle, okudala ugesi.
1. I-Anode (i-Zinc): Ku-anode, insimbi ye-zinc idlula ku-oxidation, ikhulule ama-electron bese yakha ama-ion e-zinc (Zn²⁺). Ukusabela okwenzekayo yilokhu:
\[
\text{Zn} \rightarrow \text{Zn}^{2+} + 2\text{e}^-
\]
2. I-Cathode (Ithusi): Ku-cathode, ithusi lamukela ama-electron akhishwa yi-zinc, kanti ama-ion ku-electrolyte ayancishiswa. Esimweni esilula sokusebenzisa isixazululo se-CuSO₄ njenge-electrolyte, ukusabela okwenzekayo yilokhu:
\[
\text{Cu}^{2+} + 2\text{e}^- \rightarrow \text{Cu}
\]
3. I-Electrolyte: Isixazululo se-electrolyte sisebenza njengendawo evumela ama-ion ukuthi aqhube ukushaja phakathi kwe-anode ne-cathode, kuqedelwe isekethe futhi kuvunyelwe ugesi ukuthi ugeleze ngendlela yangaphandle.
Izicelo Zakuqala kanye Neminikelo Emhlabeni Wezesayensi
Ukusungulwa kweseli le-Volta kwaba nomthelela omkhulu emhlabeni wesayensi nobuchwepheshe. Ngaphambi kokutholakala kukaVolta, ucwaningo lukagesi lwalukhawulelwe kakhulu kugesi ongashintshi. Kodwa-ke, ngomthombo wamandla oqhubekayo, ososayensi bakwazi ukwenza izivivinyo ezazingenakwenzeka ngaphambili.
1. Ukuhlolwa Kwamakhemikhali: Ikhono lokulingisa ugesi lenze osokhemisi abanjengoHumphry Davy bakwazi ukuthola izakhi ezintsha ngenqubo ye-electrolysis. Isibonelo, uDavy waphumelela ekukhipheni i-potassium, i-sodium, i-calcium, i-barium, i-strontium, kanye ne-magnesium kumakhemikhali awo emvelo.
2. Ukuthuthukiswa Kwebhethri: Amaseli e-voltaic avule indlela yokuthuthukiswa kwamabhethri asebenza kahle kakhulu. Amaseli e-voltaic ayengabanduleli bamabhethri ahlukahlukene eseli amanzi nawomile esiwasebenzisayo namuhla.
3. Ukufakwa kukagesi Kwasekuqaleni: Njengoba ihlinzeka ngomthombo kagesi ophathekayo nothembekile, inqwaba kaVolta yaba ithuluzi eliwusizo ekusungulweni kwezobuchwepheshe, okuhlanganisa nokuxhumana kwasekuqaleni njenge-telegraph.
Ukuthuthukiswa Kobuchwepheshe Bokugcina Amandla
Nakuba iseli le-Voltaic lithathelwe indawo ubuchwepheshe bebhethri besimanje, izimiso eziyisisekelo ezitholwe yi-Volta zisalokhu ziyisisekelo samadivayisi amaningi okugcina amandla namuhla. Kusukela kumabhethri alula e-alkaline kuya kumabhethri e-lithium-ion ayinkimbinkimbi asetshenziswa kumadivayisi kagesi nasezimotweni zikagesi, izimiso ezifanayo ze-electrochemical ziyasebenza.
1. Amabhethri e-Lithium-ion: Lawa angenye yentuthuko ebaluleke kakhulu kwezobuchwepheshe bebhethri lanamuhla. Njengoba amandla amaningi kanye nokuphila isikhathi eside komjikelezo, lawa mabhethri ashintshe kakhulu izimboni ze-elekthronikhi nezezimoto.
2. Amaseli Kaphethiloli e-Hydrogen: Athuthukiswe ngokusekelwe ezimisweni ezitholwe yi-Volta, kodwa esebenzisa i-hydrogen njengophethiloli, amaseli kaphethiloli anikeza izinzuzo ezibalulekile zemvelo, njengoba okuwukuphela kokukhishwa kwamanzi.
3. Ama-Supercapacitor: Nakuba ehluke ngezindlela eziningi kumabhethri endabuko, ama-supercapacitor asebenzisa izimiso ze-electrostatic kanye ne-electrochemical ukuze agcine amandla ngokushesha nangokusebenza kahle.
Imithelela Yezenhlalo Nezemvelo
Amaseli e-voltaic nawo anemiphumela emphakathini nakwezemvelo. Amandla awo okuhlinzeka ngomthombo kagesi ophathekayo nothembekile asekele intuthuko engenakubalwa kwezobuchwepheshe, kusukela kwezokwelapha kuya kwezokuxhumana. Kodwa-ke, ukuthuthukiswa kobuchwepheshe bokugcina amandla nakho kuletha izinselele zemvelo, ikakhulukazi ekulahleni nasekusetshenzisweni kabusha kwamabhethri.
1. Izinzuzo Zomphakathi: Ubuchwepheshe bebhethri buthuthukise kakhulu ikhwalithi yokuphila kwabantu. Ukusetshenziswa kwansuku zonke kwama-smartphone, ama-laptop, ngisho namadivayisi ezokwelapha kunegalelo elikhulu enduduzo nasempilweni.
2. Izinselele Zemvelo: Kodwa-ke, kukhona okubi. Ukulahlwa kwebhethri kuyinkinga enkulu ngoba kuqukethe amakhemikhali amaningi ayingozi angangcolisa imvelo. Ngakho-ke, ukutholakala nokuthuthukiswa kobuchwepheshe bokusebenzisa kabusha amabhethri kubalulekile.
Ikusasa Lobuchwepheshe Be-Voltaic Cell
Ukuthuthukiswa kobuchwepheshe bamaseli nebhethri kuzoqhubeka. Izinto ezintsha ezifana namabhethri e-solid-state, athembisa ukuminyana kwamandla aphezulu kanye nokuphepha okuthuthukisiwe, zingaphansi kocwaningo olunzulu. Ukwamukelwa kwezinto ezintsha, njenge-graphene kanye nezinto ezisetshenziswayo, kulindeleke ukuthi kuthuthukise kakhulu ukusebenza kahle kwebhethri.
1. Amabhethri Esimo Esiqinile: Ngokusebenzisa ama-electrode aqinile esikhundleni sama-electrode aketshezi, lawa mabhethri anikeza amandla amaningi kanye nokuphepha okwandisiwe, njengoba kungekho bungozi bokuvuza kwe-electrolyte okuvuthayo.
2. I-Nanotechnology: Ukusetshenziswa kwe-nanotechnology ezintweni zebhethri kungathuthukisa ukukhishwa kwamandla kanye nokusebenza kahle kwesitoreji, kwandise impilo yebhethri, futhi kunciphise isikhathi sokushaja kabusha.
Isiphetho
Ukusungulwa kuka-Alessandro Volta eminyakeni engaphezu kwamakhulu amabili edlule kwakuyisisekelo esibalulekile sentuthuko yezobuchwepheshe besimanje. Iseli le-Volta lalingelona nje kuphela ikhono lesayensi elisha, kodwa futhi laliyisisekelo esenza kwavela ukuthuthukiswa kwamadivayisi ahlukahlukene kanye nezinhlelo zokugcina amandla esizijabulelayo namuhla. Ngokuqhubeka nokuthuthukisa ezinyathelweni ze-Volta, singalindela ukubona ubuchwepheshe obuthuthukisiwe nobuqhubekayo esikhathini esizayo, bubhekana kangcono nezinselele zamandla zomhlaba wonke.
