7.2V 3000mAh baytari ku haboon Euro Pro Shark XB1918, V1917, V1950, VX3

S: Waa maxay baytari NiMH?

A: Maaddada anode ee batteriga nikkel-birta hydride waa Ni (OH) 2 (oo loo yaqaan NiO electrode), walxaha firfircoon ee korantada taban waa hydride birta, oo sidoo kale loo yaqaan 'aluminium kaydinta hydrogen (electrode waxaa loo yaqaannaa electrode kaydinta hydrogen), iyo electrolyte waa 6mol / L potassium hydroxide xal. Habka habka of wax firfircoon si ay u sameeyaan gabal electrode electrode inta badan ka mid ah sintering nooca, nooca slurry, nooca xumbo nikkel, nooca fiber nickel iyo nooca guntan, iwm Inta badan baytariyada madaniga ah sida isgaarsiintu waxay isticmaalaan nooca slurry anode iyo nooca nikkel cathode si ay u sameeyaan baytariyada. Falcelinta kiimikaad ee dallaca iyo dareeraha waa sida soo socota:

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

Elektroodh taban: M+H2O+e-=MHab+OH-

Wadarta falcelinta: Ni(OH)2+M=NiOOH+MH

Fiiro gaar ah: M: Daawaha hydrogen; Hab: adsorption of hydrogen; Habka bidix-ilaa-midig ee qaacidada fal-celintu waa habka dallacaadda; Habka midig-ilaa-bidix ee fal-celintu waa habka dheecaanka.

Inta lagu jiro dallacaadda, Ni (OH) 2 iyo OH- ee cathode waxay ka falceliyaan si ay u sameeyaan NiOOH iyo H2O, iyo e- ayaa la sii daayaa isku mar si loo dhaliyo MH iyo OH-, iyo guud ahaan falcelinta Ni (OH) 2 iyo M si ay u sameeyaan NiOOH, iyo daawaha kaydinta hydrogen waxay kaydisaa hydrogen. Si ka duwan sii daynta, MH ab waxay sii deysaa H+, H+ iyo OH- si ay u dhaliso H2O iyo e-, iyo NiOOH, H2O iyo e-soo-cusboonaysiinta Ni(OH)2 iyo OH-. Awoodda korantada ee caadiga ah ee batteriga waa 1.319V.
