7.2V 3000mAh Battery E lumellana le Euro Pro Shark XB1918, V1917, V1950, VX3

P: Betri ea NiMH ke eng?

A: Thepa ea anode ea betri ea nickel-metal hydride ke Ni (OH) 2 (e bitsoang NiO electrode), thepa e sebetsang ea electrode e mpe ke metal hydride, e tsejoang hape e le hydrogen storage alloy (electrode e bitsoa hydrogen storage electrode), 'me electrolyte ke 6mol / L hydroxide hydroxide solution. Mokhoa oa ts'ebetso oa lisebelisoa tse sebetsang ho theha sekhechana sa elektrode eleketrode haholo-holo e kenyelletsa mofuta oa sintering, mofuta oa slurry, mofuta oa foam oa nickel, mofuta oa faeba nickel le mofuta o kentsoeng, joalo-joalo, 'me li-electrode tse lokiselitsoeng ke lits'ebetso tse fapaneng li na le phapang e kholo ea bokhoni le ts'ebetso e phahameng ea hona joale, mme libeteri li hlahisoa ka kakaretso ho latela lits'ebetso tse fapaneng tlasa maemo a fapaneng. Bongata ba libeteri tsa sechaba tse kang likhokahanyo li sebelisa anode ea mofuta oa slurry le foam nickel type cathode ho etsa libeteri. Karabelo ea lik'hemik'hale tsa tefiso le ho tsoa ke tse latelang:

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

Electrode e mpe: M+H2O+e-=MHab+OH-

Kakaretso ea maikutlo: Ni(OH)2+M=NiOOH+MH

Tlhokomeliso: M: Alloy ea hydrogen; Hab: adsorption ea hydrogen; Ts'ebetso e tlohang ho le letšehali ho ea ho le letona ea foromo e sebetsang ke mokhoa oa ho tjhaja; Mokhoa o nepahetseng ho ea ho le letšehali oa karabelo ke mokhoa oa ho ntša.

Nakong ea ho tjhaja, Ni (OH) 2 le OH- ea cathode e itšoara ho theha NiOOH le H2O, 'me e-e lokolloa ka nako e le' ngoe ho hlahisa MH le OH-, 'me kakaretso ea karabelo ke Ni (OH) 2 le M ho theha NiOOH, le motsoako oa polokelo ea hydrogen o boloka hydrogen. Ho fapana le ho tsoa, ​​MH ab e lokolla H+, H+ le OH- ho hlahisa H2O le e-, le NiOOH, H2O le e- regenerate Ni(OH)2 le OH-. Matla a tloaelehileng a electromotive a betri ke 1.319V.
