ngo kim Ukuhlaziywa: Julayi 9, 2022

Ziziphi iibhetri zeNiMH? Iibhetri ze-nickel-metal hydride luhlobo lwebhetri egcwalisekayo. Zisetyenziswa kwizixhobo ezininzi ezahlukeneyo, ukusuka kwiimoto ukuya kwizinto zokudlala smartphones.

Baneenzuzo ezininzi ngaphezu kwezinye iintlobo zeebhetri, kwaye zithandwa kakhulu ngenxa yoko. Kodwa ziyintoni ngokwenene?

Imbali yeebhetri zeNiMH

I-Invention

Emuva kwi-1967, ezinye iintlantsi eziqaqambileyo kwi-Battelle-Geneva Research Centre zine-brainwave kwaye zaqulunqa ibhetri ye-NiMH. Yayisekwe kumxube we-Sintered Ti2Ni+TiNi+x alloys kunye ne-NiOOH electrode. UDaimler-Benz kunye neVolkswagen AG babandakanyeka kwaye baxhasa uphuhliso lwebhetri kwiminyaka engamashumi amabini ezayo.

Uphuculo

Ngeminyaka yoo-70s, ibhetri yenickel-hydrogen yathengiswa kwi-satellite applications, kwaye oku kwavuselela umdla kubuchwepheshe behydride njengenye indawo yokugcina i-hydrogen enkulu. I-Philips Laboratories kunye ne-CNRS yaseFransi iphuhlise i-alloys entsha ene-high-energy hybrid edibanisa iintsimbi ezinqabileyo zomhlaba ze-electrode engalunganga. Kodwa ezi ngxubevange azizange zizinzile kwi-alkaline electrolyte, ngoko ke zazingafanelekanga ukuba zisetyenziswe ngabathengi.

Ukuphumelela

Ngomnyaka we-1987, uWillems noBuschow benza impumelelo kunye noyilo lwabo lwebhetri, olusebenzisa umxube weLa0.8Nd0.2Ni2.5Co2.4Si0.1. Le bhetri igcine i-84% yomthamo wayo wokutshaja emva kwe-4000 ye-charge-discharge cycles. Iialloyi ezisebenzisekayo ngakumbi kwezoqoqosho zisebenzisa i-mischmetal endaweni ye-lanthanum zaphuhliswa ngokukhawuleza.

IBanga labaThengi

Kwi-1989, iiseli ze-NiMH zokuqala zabathengi zafumaneka, kwaye kwi-1998, i-Ovonic Battery Co. Ngo-2008, ngaphezu kwezigidi ezibini zeemoto ezixutywe kwihlabathi jikelele zenziwe ngeebhetri ze-NiMH.

Ukuduma

KwiManyano yaseYurophu, iibhetri ze-NiMH zithathe indawo yeebhetri ze-Ni-Cd ukuze zisetyenziswe ngabathengi. EJapan kwi-2010, i-22% yeebhetri eziphathwayo ezithengiswayo zithengiswa yi-NiMH, kwaye eSwitzerland kwi-2009, i-statistic elinganayo yayimalunga ne-60%. Kodwa le pesenti iye yehla ngokuhamba kwexesha ngenxa yokwanda kokwenziwa kweebhetri ze-lithium-ion.

Ngelixa elizayo

Kwi-2015, i-BASF yavelisa i-microstructure eguquliweyo eyenza ukuba iibhetri ze-NiMH ziqine ngakumbi, zivumela utshintsho kwi-design yeseli eyagcina ubunzima obuninzi kwaye yandisa amandla athile kwiiyure ze-140 ngekhilogram. Ngoko ikamva leebhetri zeNiMH libukeka liqaqambile!

IKhemistri eNgemva kweebhetri zeNickel-Metal Hydride

Yintoni i-Electrochemistry?

Electrochemistry luphononongo lobudlelwane phakathi kombane kunye neekhemikhali. Yinzululwazi emva kweebhetri, kwaye yindlela iibhetri zeNickel-Metal Hydride (NiMH) ezisebenza ngayo.

Iimpendulo Ngaphakathi kwebhetri ye-NiMH

Iibhetri ze-NiMH zenziwe ngee-electrode ezimbini, i-positive kunye ne-negative. Iimpendulo ezenzeka ngaphakathi kwebhetri zizo eziyenza isebenze. Nantsi into eyenzekayo:

• Kwi-electrode engalunganga, amanzi kunye nentsimbi idibanisa ne-electron ukwenza i-OH- kunye ne-hydride yensimbi.
• Kwi-electrode elungileyo, i-nickel oxyhydroxide yenziwa xa i-nickel hydroxide kunye ne-OH- idibanisa ne-electron.
• Ngexesha lokutshaja, iimpendulo zihamba ukusuka ekhohlo ukuya ekunene. Ngexesha lokukhupha, iimpendulo zihamba ukusuka ekunene ukuya ngasekhohlo.

Amacandelo ebhetri ye-NiMH

I-electrode engalunganga yebhetri ye-NiMH yenziwe yi-intermetallic compound. Olona hlobo luxhaphakileyo yi-AB5, engumxube wezinto ezinqabileyo zomhlaba ezifana nelanthanum, cerium, neodymium, kunye nepraseodymium, kudityaniswe nenickel, cobalt, manganese, okanye ialuminium.

Ezinye iibhetri ze-NiMH zisebenzisa izinto eziphezulu ze-electrode ezimbi ezisekelwe kwi-AB2 iikhompawundi, eziyi-titanium okanye i-vanadium edityaniswe ne-zirconium okanye i-nickel, kwaye iguqulwe nge-chromium, i-cobalt, isinyithi, okanye i-manganese.

I-electrolyte kwibhetri ye-NiMH idla ngokuba yi-potassium hydroxide, kwaye i-electrode e-positive yi-nickel hydroxide. I-electrode engalunganga yi-hydrogen ngendlela ye-interstitial metal hydride. I-Nonwoven polyolefin isetyenziselwa ukwahlula.

Ngoko ke unayo! Ngoku uyazi ikhemistri emva kweebhetri zeNiMH.
