I-7.2V 3000mAh Ibhethri Ihambisana ne-Euro Pro Shark XB1918, V1917, V1950, VX3

Q: Liyini ibhethri le-NiMH?

A:Impahla ye-anode yebhethri ye-nickel-metal hydride yi-Ni(OH)2(ebizwa nge-NiO electrode), into esebenzayo ye-electrode engeyinhle i-metal hydride, eyaziwa nangokuthi i-hydrogen storage alloy (i-electrode ibizwa ngokuthi i-hydrogen storage electrode), kanti i-electrolyte iyisixazululo esingu-6mol/L se-potassium hydroxide. Imodi yenqubo yezinto ezisebenzayo ukwakha ucezu lwe-electrode electrode ikakhulukazi ihlanganisa uhlobo lwe-sintering, uhlobo lwe-slurry, uhlobo lwe-nickel foam, uhlobo lwe-fiber nickel nohlobo olushunyekiwe, njll. Amabhethri amaningi omphakathi afana nezokuxhumana asebenzisa uhlobo lwe-slurry anode kanye ne-foam nickel type cathode ukwenza amabhethri. I-chemical reaction of charge and discharge imi kanje:

I-Cathode: Ni(OH)2+OH-=NiOOH+H2O+e-

I-electrode engalungile: M+H2O+e-=MHab+OH-

Isamba sokusabela: Ni(OH)2+M=NiOOH+MH

Qaphela: M: Ingxubevange ye-Hydrogen; Hab: i-adsorption ye-hydrogen; Inqubo esuka kwesokunxele iye kwesokudla yefomula esebenzayo iyinqubo yokushaja; Inqubo esuka kwesokudla kuye kwesokunxele yokusabela yinqubo yokukhipha.

Ngesikhathi sokushaja, i-Ni(OH)2 ne-OH- ye-cathode isabela ekwakheni i-NiOOH ne-H2O, futhi i-e- ikhishwa ngesikhathi esifanayo ukuze kukhiqizwe i-MH ne-OH-, futhi ukusabela okuphelele kungu-Ni(OH)2 no-M ukuze kwakhiwe i-NiOOH, kanti i-hydrogen storage alloy igcina i-hydrogen. Ngokuphambene nokukhishwa, i-MH ab ikhipha i-H+, H+ ne-OH- ukuze ikhiqize i-H2O ne-e-, ne-NiOOH, H2O kanye ne-e- regenerate Ni(OH)2 kanye ne-OH-. Amandla ajwayelekile e-electromotive ebhethri ngu-1.319V.
