Amabhethri e-NiMH: Ayini?

ngo kim Kubuyekezwe: July 9, 2022

Ayini amabhethri e-NiMH? Amabhethri e-nickel-metal hydride awuhlobo lwebhethri elishajekayo. Asetshenziswa kumishini eminingi ehlukene, kusukela ezimotweni kuya kumathoyizi Smartphones.

Zinezinzuzo eziningi kunezinye izinhlobo zamabhethri, futhi zithandwa kakhulu ngenxa yalokho. Kodwa ziyini ngempela?

Umlando Wamabhethri e-NiMH

I-Invention

Emuva ngo-1967, ezinye izinhlansi ezikhanyayo e-Battelle-Geneva Research Centre zaba ne-brainwave futhi zasungula ibhethri ye-NiMH. Isekelwe ekuhlanganisweni kwama-alloys e-Ti2Ni+TiNi+x ahlanganisiwe nama-electrode e-NiOOH. I-Daimler-Benz kanye neVolkswagen AG bazibandakanya futhi baxhasa ukuthuthukiswa kwebhethri eminyakeni engamashumi amabili ezayo.

Ukuthuthukiswa

Ngama-70s, ibhethri le-nickel-hydrogen lathengiswa ukuze lisetshenziswe ngesathelayithi, futhi lokhu kwavusa isasasa kubuchwepheshe be-hydride njengenye indawo yokugcina i-hydrogen enkulu. I-Philips Laboratories kanye ne-CNRS yase-France bathuthukise ama-alloys amasha ahlanganisa amandla aphezulu ahlanganisa izinsimbi ezingavamile zomhlaba ze-electrode engeyinhle. Kodwa lawa ma-alloys ayengaqinile ku-alkaline electrolyte, ngakho-ke ayengafanele ukusetshenziswa kwabathengi.

Ukuqhuma

Ngo-1987, uWillems noBuschow benza intuthuko ngomklamo wabo webhethri, owasebenzisa ingxube ye-La0.8Nd0.2Ni2.5Co2.4Si0.1. Leli bhethri ligcine u-84% womthamo walo wokushaja ngemva kwemijikelezo engu-4000 yokushaja–yokukhipha. Ama-alloys anamandla ngokwezomnotho asebenzisa i-mischmetal esikhundleni se-lanthanum athuthukiswa ngokushesha.

Ibanga Lomthengi

Ngo-1989, amaseli e-NiMH ebanga lomthengi lokuqala atholakala, futhi ngo-1998, i-Ovonic Battery Co. Ngo-2008, izimoto ezingama-hybrid ezingaphezu kwezigidi ezimbili emhlabeni wonke zakhiwe ngamabhethri e-NiMH.

Ukuduma

E-European Union, amabhethri e-NiMH athathe indawo yamabhethri e-Ni-Cd ukuze asetshenziswe umthengi ophathekayo. E-Japan ngo-2010, u-22% wamabhethri aphathekayo aphinde washajwa athengiswa kwakuyi-NiMH, futhi e-Switzerland ngo-2009, izibalo ezilinganayo zazicishe zibe ngama-60%. Kodwa leli phesenti liye lehla ngokuhamba kwesikhathi ngenxa yokwanda kokukhiqizwa kwamabhethri e-lithium-ion.

The Future

Ngo-2015, i-BASF yakhiqiza i-microstructure eguquliwe eyenza amabhethri e-NiMH ahlala isikhathi eside, okuvumela izinguquko ekwakhiweni kwamaseli okusindisa isisindo esikhulu futhi kwandise amandla athile ku-140 watt-amahora ngekhilogremu. Ngakho ikusasa lamabhethri e-NiMH libukeka liqhakazile!

Ikhemistry Engemuva Kwamabhethri e-Nickel-Metal Hydride

Iyini i-Electrochemistry?

I-Electrochemistry iwucwaningo lobudlelwano phakathi kukagesi nokusabela kwamakhemikhali. Isayensi engemuva kwamabhethri, futhi yindlela amabhethri e-Nickel-Metal Hydride (NiMH) asebenza ngayo.

Ukusabela Ngaphakathi Kwebhethri le-NiMH

Amabhethri e-NiMH akhiwe ngama-electrode amabili, iphozithivu nenegethivu. Ukusabela okwenzeka ngaphakathi kwebhethri yikho okuyenza isebenze. Nakhu okwenzekayo:

• Ku-electrode engalungile, amanzi nensimbi kuhlangana ne-electron ukuze kwakhiwe i-OH- ne-hydride yensimbi.
• Ku-electrode eqondile, i-nickel oxyhydroxide yakheka lapho i-nickel hydroxide ne-OH- ihlangana ne-electron.
• Ngesikhathi sokushaja, ukusabela kuhamba ukusuka kwesokunxele kuye kwesokudla. Ngesikhathi sokukhipha, ukusabela kuhamba ukusuka kwesokudla kuye kwesokunxele.

Izingxenye Zebhethri le-NiMH

I-electrode eyinegethivu yebhethri ye-NiMH yenziwe ngenhlanganisela ye-intermetallic. Uhlobo oluvame kakhulu i-AB5, okuyingxube yezinto ezingavamile zomhlaba njenge-lanthanum, i-cerium, i-neodymium, ne-praseodymium, ehlanganiswe ne-nickel, i-cobalt, i-manganese, noma i-aluminium.

Amanye amabhethri e-NiMH asebenzisa amandla aphezulu e-electrode engasebenzi kahle esekelwe kuzinhlanganisela ze-AB2, okuyi-titanium noma i-vanadium ehlanganiswe ne-zirconium noma i-nickel, futhi ilungiswe nge-chromium, i-cobalt, insimbi, noma i-manganese.

I-electrolyte ebhethri ye-NiMH ivamise ukuba yi-potassium hydroxide, kanti i-electrode enhle i-nickel hydroxide. I-electrode engeyinhle iyi-hydrogen esesimweni se-interstitial metal hydride. I-Nonwoven polyolefin isetshenziselwa ukuhlukanisa.

Ngakho-ke usunakho! Manje uyazi i-chemistry ngemuva kwamabhethri e-NiMH.

Liyini Ibhethri Le-Bipolar?

Yini eyenza amabhethri e-Bipolar ahluke?

Amabhethri e-Bipolar ahluke kancane kunamabhethri akho ajwayelekile. Basebenzisa isihlukanisi sejeli se-polymer eqinile, esiza ukuvimbela ama-short-circuits ukuthi angenzeki ezinhlelweni ze-liquid-electrolyte. Lokhu kubenza babe ukukhetha okuhle ezimotweni zikagesi, njengoba zikwazi ukugcina amandla amaningi futhi ziwagcine ephephile.

Kungani Kufanele Ngikhathalele Amabhethri E-Bipolar?

Uma ufuna ibhethri elingagcina amandla amaningi futhi liwagcine liphephile, ibhethri le-bipolar lingase libe inketho elungile kuwe. Ziya ngokuya ziduma ezimotweni zikagesi, ngakho-ke uma ufuna eyodwa, kufanele nakanjani ucabangele ibhethri le-bipolar. Nasi isizathu:

• Zenzelwe ukuvimbela ama-short-circuits ukuthi angenzeki kumasistimu e-liquid-electrolyte.
• Ziyakwazi ukugcina amandla amaningi, okuzenza zilungele izimoto ezisebenza ngogesi.
• Ziya ngokuya ziduma, ngakho ungaqiniseka ukuthi uthola umkhiqizo wekhwalithi.

Ukushaja Amabhethri Akho e-NiMH Ngokuphephile

Ukushaja Ngokushesha

Uma ujahile futhi udinga ukushaja amaseli akho e-NiMH, kungcono kakhulu ukusebenzisa ibhethri elihlakaniphile ishaja ukugwema ukushajwa ngokweqile, okungalimaza amaseli. Nawa amanye amathiphu okufanele uwakhumbule:

• Sebenzisa umsinga ophansi ongashintshi, onesibali sikhathi noma ongenaso.
• Ungakhokhisi isikhathi esingaphezu kwamahora angu-10-20.
